As espécies de forrageiras, em especial as do genêro Urochola tem sido uma importante alternativa para utilização no Sistema de Plantio Direto (SPD) devido a boa produção de biomassa e alta relação C/N. Essas características favorecem a persistência da palhada na área, principalmente em regiões como o Cerrado, onde as condições climáticas aceleram a decomposição da palhada. Contudo, para o bom desenvolvimento da cultura subsequente, deve-se realizar a dessecação dessas forrageiras de maneira eficiente, com a utilização de herbicidas. Deste modo, objetivou-se nesse trabalho a investigação da cinética de morte das forrageiras Urochola brizantha cv.Piatã, a U. brizantha cv. BRS Paiaguás, U. spp cv. Ipyporã e U. ruziziensis submetidas a diferentes doses do herbicida glifosato. Os tratamentos consistiram na combinação de quatro espécies forrageiras (Urochloa brizantha cv. BRS Paiaguás, U. ruziziensis, U. brizantha cv. Piatã e U. spp. cv. Ipyporã) submetidas à aplicação de quatro doses do herbicida glifosato (250; 500; 1000 e 2000 g de equivalente ácido de glifosato ha-1). Foram realizadas avaliações visuais do efeito fitotóxico aos 7, 14, 21 e 28 dias após a aplicação (DAA) do herbicida. Os resultados demonstram que as espécies possuem sensibilidade diferente ao herbicida glifosato, sendo que as U. brizantha cv. BRS Paiaguás e U. ruziziensis as mais susceptíveis ao herbicida. A cinética de morte das forrageiras é afetada pela dose aplicada do herbicida.

ABSTRACT Cerrado biome is responsible for part of Brazilian food production. However, due to inadequate soil management practices, large areas of crop and forage are degraded, leading to environmental and economic losses. A crop-livestock-forest system (CLFS) is a sustainable production strategy that integrates different cultivations. This objective of this study was to evaluate agronomic characteristics and maize (Zea mayz L.) yield when consorciated with Panicum maximum cv. Tamani, cultivated between rows of eucalypts clones. The statistical design used was randomized blocks, constituted by the following treatments: Maize + AEC 043; Maize + AEC 007; Maize + AEC 2111; and Maize + AEC 2034. The analyzed variables included: spikes length, number of rows, number of grains per row, number of grains per spike, and grain yield. Based on the obtained data, it is possible to conclude that trees did not affect maize yield in a CLFS. Considering that only 66% of the area was used for agriculture, maize yield was higher than when it is planted in total area.

http://dx.doi.org/10.5902/198050989278This study was conducted in a 27 year Pinus taeda stand in Cambará do Sul, Rio Grande do Sul state and aimed to estimate the biomass production, nutrient stock and to evaluate the nutritional impact in different forest harvesting intensities. Biomass was estimated through regression equation adjustments, with the cut of 15 trees distributed in 5 diametric classes. Nutrients stock was obtained through the product between the average content of nutrients in each biomass component and the number of trees per diametric class per hectare. Pinus taeda above ground biomass was estimated in 266.08 Mg ha-1, being 69.1% of wood, 17.1 of live branches, 6.7% of bark, 3.8% of dead branches and 3.4% of needles. Nutrients stock in biomass (kg ha-1) was estimated in: 511.96 of N, 44.39 of P, 174.27 of K, 310.77 of Ca, 103.80 of Mg, 115.36 of S, 2.94 of B, 0.62 of Cu, 17.34 of Fe, 36.70 of Mn and 4.46 of Zn. Nutrients stock relative distribution in Pinus taeda biomass components showed the following sequence: wood (43.6%), live branches (24.8%), needles (19.0%), bark (8.7%) and dead branches (3.9%). Total above ground biomass harvest, when compared to only wood removal, leads to nutrients export increase that can vary from 58.0% to 127.4%, depending on the chemical element, while biomass removal increases 40.8%.

This study had as objective to quantify biomass and nutrients, in an 18 months Eucalyptus urograndis stand in southeastern mountain range, Piratini-RS. Twenty-four (24) plots (15.0 m x 22.5 m) were allocated; after that, one tree (with diameter at breast height) was felled in each plot. The tree was fractionated in the following fractions of above ground biomass: wood, bark, branches and leaves. Total biomass was 18.5 Mg ha-1, being the wood the fraction with highest biomass (37%), followed by branches (34.2%), leaves (21.3%) and bark (7.6%). Leaves showed highest nutrients concentrations, being statistically superior to other fractions (p N > K > Mg > P > S, and for micronutrients was Mn > Fe > B > Zn > Cu. Highest amount of nutrients is contained on leaves component, due to the highest nutrients concentration, excepted for Ca, Mg and Cu that are located in large quantities in the branches.Objetivou-se quantificar a biomassa e os nutrientes, em povoamentos de Eucalyptus urograndis, aos 18 meses de idade na serra do sudeste, Piratini-RS.

This study, conducted in a 27-year-old Araucaria angustifolia stand in the municipality of Quedas do Iguaçu (PR) county, aimed to estimate tree components, understory and accumulated litter biomasses. Biomass was estimated through regression equation adjustments, with 21 trees felled, distributed among 7 diametric classes, and with litter and understory based on known sample unit areas. Total stand biomass was 241.92 Mg ha-1, with 82.2% composed of Araucaria angustifolia, 9.6% composed of understory and 8.2% composed by litter. Considering only Araucaria angustifolia, the biomass was of 198.62 Mg ha-1, composed of wood (51.5%), bark (14.7%), roots (13.0%), lives branches (11.8%), aciculated branches (6.6%) and dead branches (0.5%). Relative biomass production for the wood component may be low, when compared to other forest species, mainly due to the high allocation in the bark component.

Esta pesquisa investigou a relação entre o incremento de espécies arbóreas nativas do bioma Cerrado e o porte inicial das mudas plantadas, em função de irrigação e aplicação de polímero hidroretentor nas covas de plantio. O experimento foi instalado em uma área degradada pela exploração mineral de areia quartzítica, no Distrito Federal. Foram delineados quatro blocos de quatro parcelas de 20 x 50 m, com 10 indivíduos de cada uma das 11 espécies de Cerrado selecionadas por parcela, totalizando 110 mudas em cada parcela. Foram feitas avaliações de crescimento, medindo-se os Diâmetros à Altura do Coleto e as alturas totais das plantas em fevereiro de 2010 e em agosto de 2011. Os resultados indicaram variação entre e dentro de espécies no crescimento em altura (H) e diâmetro à altura do coleto (DAC), mas sem associação com os tratamentos de irrigação e aplicação de polímero. O crescimento relativo médio em altura e diâmetro foram maiores nas espécies que apresentavam os menores portes iniciais, e diminuíram na medida em que o porte inicial das mudas era maior. Dessa forma, conclui-se que o porte inicial não foi fator limitante ao desenvolvimento das plantas no campo.

Brazilian savanna (Cerrado) trees present high diversity, whether they are being used by fauna and traditional populations as food or medicine. However, little research has been done to evaluate the nutrient composition of different species relevant to society, which may highlight new uses of these species. The objective of this study was to characterize nutritional aspects of the leaves of different Cerrado native species. Bromatological analyses (i.e. dry matter (DM), total digestible nutrients (TDN), crude protein (CP), ether extract (EE), crude fiber (CF), mineral matter (MM), and nutrient concentration were performed on five native tree species (Inga cylindrica; Platymiscium floribundum, Piptadenia gonoacantha, Anadenanthera macrocarpa, and Dipteryx alata) that presented potential for animal feed, according to farmer’s reports. The chemical characteristics of the leaves of Cerrado trees were characterized and compared between them. All five species evaluated in this study showed nutritional characteristics that suggest their potential use for animal feed, especially the P. floribundum, I. cylindrica, and P. gonoacantha for their high protein value.

Plant Science ,Agronomy and Crop Science - Abstract
Intercropping imidazolinone resistance crops, resistant to herbicides imazapyr + imazapic, with forage species may be a viable alternative to recover degraded pasture areas. This practice requires herbicides to slow down development of the forage and avoid reduced rice yield. However, as it is a relatively new technology, the proper management of this herbicide to control forage is not known. The objective of this study was to determine the susceptibility of forages Urochloa ruziziensis, U. brizantha cv. Paiaguás, and U. brizantha cv. Marandu, submitted to the pre-emergence application of the herbicides [imazapyr + imazapic]. The experimental design was completely randomized in a 3×5+3 factorial scheme with five replications. Treatments consisted of the combination of the three species (Urochloa ruziziensis, U. brizantha cv. Paiaguás, and U. brizantha cv. Marandu) and five intervals between herbicide application in the soil and forage sowing (0; 5; 10; 15; and 20 days after its application), in addition to three control treatments, without herbicide application. This study found that application of herbicide on the day of forage sowing for intercropping with imidazolinone resistance crops is not feasible. Increasing the time interval between herbicide application and forage sowing provides increased development of U. brizantha cvs. Marandu and Paiaguás. The species U. ruziziensis is more susceptible to pre-emergence application imazapyr + imazapic. According to the results, U. brizantha cvs. Marandu and Paiaguás are more suitable to be managed by imidazolinone herbicides to recover degraded pasture areas

Forage species, mainly those from the Urochloa genus, have been an essential alternative for utilization in no-tillage systems (NTS) due to their high biomass production and C/N ratio. However, for adequate development of the subsequent crops, the desiccation of forage plants must be efficient using herbicides. This study aimed to investigate the death kinetics of forage species from the Urochloa genus submitted to different levels of glyphosate. The treatments consisted of four forage species (Urochloa brizantha cv. BRS Paiaguás, U. ruziziensis, U. brizantha cv. Piatã, and U. spp. cv. Ipyporã) submitted to four doses of glyphosate (250; 500; 1,000 and 2,000 g a.e. ha-1). Visual assessments about the phytotoxic effect were made on 7, 14, 21, and 28 days after application (DAA). The evaluated species have different sensitivities to glyphosate and U. brizantha cv. BRS Paiaguás and U. ruziziensis are the most susceptible to this herbicide. The doses of herbicide affect the death kinetics of these forage species. Higher doses of glyphosate reduce the desiccation time of these forage plants. As espécies de forrageiras, em especial as do genêro Urochola tem sido uma importante alternativa para utilização no Sistema de Plantio Direto (SPD) devido a boa produção de biomassa e alta relação C/N.

Integrated systems are sustainable alternatives, where agricultural, forestry, and/or livestock components occupy a given area through consortium, rotation, or succession. Considering this importance, this work had as objective to quantify the stock of above-ground biomass (wood, leaves, bark, and branches) of 6 years Eucalyptus urograndis in a crop-livestock-forest integration system (CLFS). It also involved calculation of the nutrient utilization in biomass conversion through the Biological Utilization Coefficient (BUC) and design of different export scenarios of these nutrients through the harvest in order to calculate the reduction in the demand for inputs. Nutrient stock was determined from the biomass sampled in the field and from the plant tissue analysis. It is verified that the highest concentrations of macronutrients are present in wood component, except for Ca. The concentration gradient of micronutrients was: Leaves> Fe> Mn> B> Cu> Zn; Branches and Bark: Fe> Mn > B> Zn> Cu; and wood: Mn > Fe > Zn > Cu > B. Considering BUC conversion rate decline, it presented the following order: S> P> Mg> Ca> N> K for macronutrients and B> Cu> Zn> Fe> Mn for micronutrients. The most appropriate export scenario was to harvest only timber component to minimize the nutritional export. The nutritional dynamics within the eucalyptus are altered according to the diametric structure of the trees. The nutritional elements are concentrated in different compartments according to the availability and need of the plants.

Cerrado biome is responsible for part of Brazilian food production. However, due to inadequate soil management practices, large areas of crop and forage are degraded, leading to environmental and economic losses. A crop-livestock-forest system (CLFS) is a sustainable production strategy that integrates different cultivations. This objective of this study was to evaluate agronomic characteristics and maize (Zea mayz L.) yield when consorciated with Panicum maximum cv. Tamani, cultivated between rows of eucalypts clones. The statistical design used was randomized blocks, constituted by the following treatments: Maize + AEC 043; Maize + AEC 007; Maize + AEC 2111; and Maize + AEC 2034. The analyzed variables included: spikes length, number of rows, number of grains per row, number of grains per spike, and grain yield. Based on the obtained data, it is possible to conclude that trees did not affect maize yield in a CLFS. Considering that only 66% of the area was used for agriculture, maize yield was higher than when it is planted in total area.

Aims: This study performed the adjustment of volumetric models, and determined the biomass of Eucalyptus grandis x Eucalyptus urophylla hybrid cultivated in a crop-livestock-forest integration system (CLF). Study Design: The experimental area consists of a crop-livestock-forest integration system where trees are hybrids clones of seven year old Eucalyptus grandis x Eucalyptus urophylla. Place and Duration of Study: This work was carried out at Fazenda Santa Brígida, Ipameri, Goiás (Brazil). Methodology: A forest inventory of the area was carried out in October 2015 when the tree component was fully developed. Diameter at breast height (DBH) (at 1.30 m) and total height (H) of trees were measured in the field and categorized according to 4 classes. Afterwards, 12 trees were felled, which were cubed and compartmentalized to determine the volume and biomass of their components. The volumetric models developed by Schumacher & Hall and Ogaya were applied to obtain determination coefficients. Results: The average DBH was 18.28 cm and the average H was 23.47 m. The highest volumes of wood were observed in the diametric classes that presented the largest number of individuals, however in the class of higher DBH an average individual volume of 0.36 m3 of wood was observed. The total biomass of Eucalyptus was 56.64 Mg ha-1, being 83.70% wood, 6.52% in branches, 6.37% in bark and 3.40% in leaves. Conclusion: The volumetric models developed by Schumacher and Hall as well as Ogaya were found to be applicable for estimating the volume of wood in CLF systems, where both showed a determination coefficient of 0.866.

O objetivo deste estudo foi avaliar a produção de biomassa e estoque de nutrientes na serapilheira acumulada em plantios de quatro clones de eucalipto (AEC-2034 (Eucalyptus camaldulensis x E. grandis) x E. urophylla)), AEC-2111 (E. urophylla x (E. camaldulensis x E. grandis)), AEC-007 (E. toreliana x E. citriodora) e o AEC-0043 (E. citriodora x E. toreliana) aos quatro anos e meio, em sistema integrado de Lavoura-Pecuária-Floresta (ILPF), em Inaciolândia – Goiás. Para a coleta de serapilheira (folhas, galhos, casca e miscelânea) foi utilizado um gabarito de área de 0,0625 m². Foram coletadas 20 amostras de serapilheira aleatoriamente em cada clone, totalizando 80 amostras. Em laboratório, todo material foi processado através de secagem, pesagem e moagem para determinação de biomassa e análises de teor nutricional. O acúmulo na produção média total de serapilheira acumulada foi de 6,07 Mg ha-1 para o clone AEC-2034, 5,20 Mg ha-1 para o clone AEC-2111, 3,41 Mg ha-1 para o clone AEC-007 e 3,23 Mg ha-1 para o clone AEC-0043. O componente folha apresentou o maior acúmulo total de nutrientes em todos os clones. O nitrogênio (N) foi o elemento com maior estoque na serapilheira acumulada em todos os clones. O maior acúmulo de biomassa de serapilheira ocorreu no clone AEC-2034 e o componente mais representativo foi a folha. O clone AEC-2034 apresentou maior estoque de nutrientes na serapilheira e o clone AEC-0043 o menor estoque. O macronutriente com maior acúmulo nos componentes avaliados foi o nitrogênio (N) e o micronutriente foi o ferro (Fe). Com base no acúmulo de serapilheira e devolução de nutrientes, o clone mais indicado em sistema ILPF nessa região é o clone AEC-2034.

No. of bitstreams: 0 Previous issue date: 2018-03-01 Agricultural use and management systems in tropical soils of the Brazilian Cerrado may directly influence its chemical properties, in the conventional cultivation systems with pastures or grains, as well as in areas with a crop-livestock-forest integration system. Thus, the objective was to evaluate the chemical attributes of the soil under different use and management systems. The research was carried out at Boa Vereda Farm, in the state of Goiás, Brazil. The experimental design was completely randomized with a 5 x 3 factorial arrangement divided into five production systems: (1) among the rows of Eucalyptus (CLFI), (2) within the rows of Eucalyptus (CLFI), (3) in conventional agricultural monoculture, (4) pasture, and (5) - natural Cerrado (control treatment). Samples were collected in three soil depths (0-0.5; 0.5-0.1 and 0.1-0.2 m), with four replicates each. Among the chemical properties of the soil studied, the organic matter, calcium, magnesium and potassium contents, base saturation, and cation exchange capacity, are higher in the soil with natural Cerrado. The area of agricultural monoculture showed the highest levels of phosphorus and copper, but has the lower levels of organic matter in the soil. The chemical properties of the soil were similar in the CLFI system, regardless of the evaluation point (within or among rows). The chemical properties of the soil evaluated were similar between the pasture cultivated in CLFI and the conventional system. Therefore, the land use and management system do not directly influence the chemical properties of the soils evaluated.

The crop-livestock-forest integration systems are a form of sustainable production, creating a consortium between the cultivation of crops and forest production and the creation of pastures for livestock breeding, seeking a synergy between the system components. Therefore, integrating agricultural crops with tree species provides countless benefits to the components, such as the maintenance and increase in nutrient cycling. Therefore, the objective of this study was to evaluate the biomass and nutritional stock of Brachiaria pasture and accumulated litter in a silvopastoral system with tree species of the Cerrado. Three silvopastoral systems, formed with the forage species Urochloa decumbens (Brachiaria) integrated with three tree species, namely Dipteryx alata (baru tree), Caryocar brasiliense (pequi) and Eugenia dysenterica (cagaita), were evaluated. Litter and pasture were collected in each system at different sample distances from the tree. The amount of biomass and the nutritional contents of both components were evaluated by chemical analysis. The largest amount Brachiaria pasture biomass and largest amount of litter was found in the silvopastoral system with baru trees. The pasture differed nutritionally. The pastures associated with baru trees and to pequis have higher amounts of macronutrients. There are nutritional differences with respect to the sampling positions. Key words: Brachiaria, Baru, Pequi, Cagaita, CLFi, Cerrado, Brazil.

The reuse of organic byproducts in agroforestry systems is a sustainable proposal, since, in addition to preserving the natural resources, it has allowed the fertilization of the soils, obtaining a reduction of costs with mineral fertilizers. Therefore, the objective of this research was to evaluate the chemical attributes of the soil after two years of successive fertilizations using cattle manure and sewage sludge in agroforestry systems. The study was conducted in Goiânia, state of Goias, Brazil. The experimental design used randomized blocks on a 2 x 4 factorial (cultivation systems and fertilizations), with four repetitions. The cultivation systems were: agroforestry and monoculture systems. The fertilizations used were: cattle manure, sewage sludge, mineral fertilizer and control (no fertilization). Regardless of the cultivation system, the fertilizations with sewage sludge increases the calcium, phosphor and zinc contents of the soil, as well as the pH values, sum of bases and cation exchange capacity, at 0-10cm depth. However, the potassium contents are lower in relation to the use of mineral fertilizers, both at 0 to 10 cm depth and at 0 to 20 cm. Teak plants in agroforestry systems presents similar heights to the monoculture plants, and they are higher on fertilizations with sewage sludge. The soybean grain productivity in the agroforestry system presents similar outputs in relation to the use of sewage sludge and mineral fertilizers. Therefore, it is recommended for farmers to adopt agroforestry systems and the organic fertilization practice with sewage sludge, associating the quality of the chemical attributes of the soil, the growth of forest species and soybean grain yields. Key words: Tectona grandis, sewage sludge, cattle manure, intercropping systems, soybeans.

The influence of the forest component in the crop-livestock-forest integration system depends on several factors, among which are the plant species used and the row spacing established in system deployment. Therefore, the objective of this study was to characterize the tree component dendrometrically using Eucalyptus grandis x urograndis individuals from the CLFI system and to determine the model fit with volumetric models of homogeneous stands. The study area consists of a six year old CLFI system of Eucalyptus grandis x urophylla, located at the municipality of Cachoeira Dourada – GO. Forest inventory and volume measurement were carried out through the Smalian method. The hypsometric relations of Eucalyptus urograndis were adjusted to seven volumetric models. The arrangement proposed in the crop-livestock-forest integration system (CLFI) was efficient. The models tested (Naslund, Ogaya, Schumacher & Hall, Spurr logarithmic, Honner, Takata and Husch) showed adjustments above 87%, where the models Naslund (99.53%) and Ogaya (99.17%) had the best fit.

A serapilheira e o principal componente que mantem a produtividade da floresta, com a ciclagem dos nutrientes. Este trabalho teve por objetivo quantificar o acumulo de serapilheira e suas compartimentalizacoes em quatro tipos de vegetacao, sendo uma area de Cerrado sentido restrito, uma mata de galeria, um plantio de eucalipto e outro de pinus. Em cada area foram coletadas 30 amostras aleatorias de serapilheira utilizando uma moldura de madeira de 25cm x 25cm. As amostras foram pesadas secas e depois separadas em compartimentos (folha/aciculas, galhos, casca, material reprodutivo e miscelânea). A fracao folhas/aciculas e a que mais contribui para a formacao da serapilheira, seguido dos galhos, devido a senescencia e reposicao de novas folhas. O pinus possui maior quantidade total de serapilheira, devido ao plantio ser mais antigo e a decomposicao de aciculas serem mais lenta. As formacoes florestais apresentam o mesmo padrao quantidade e compartimentalizacao de serapilheira.

1 recurso en línea (páginas 425-435)., El uso inapropiado de agroquímicos es perjudicial para las abejas que visitan los cultivos agrícolas, lo que reduce la producción por la afectación de la polinización y son pocos los estudios sobre este tema. El objetivo de este estudio fue verificar la incidencia de diferentes fungicidas sobre la visita de abejas en cultivos de tomate y sus efectos sobre la deposición de granos de polen en el estigma, número de semillas, masa y tamaño del fruto. Los experimentos consistieron en 10 tratamientos que fueron: (T1) tratamiento control sin agroquímicos; (T2 y T3) Bacillus subtilis en diferentes frecuencias de aplicación; (T4) hidróxido de cobre; (T5) B. subtilis e hidróxido de cobre; (T6) acibenzolar-S-metilo; (T7) trifloxistrobina+tebuconazol y B. subtilis; (T8) hidróxido de cobre + Mancozeb; (T9) propineb+(-trifloxistrobina+tebuconazol); (T10) trifloxistrobina+tebuconazol)+B. subtilis+hidróxido de cobre. Se determinó la presencia de la marca de polinización en la flor, la carga de polen en los estigmas, el número de semillas por fruto, y el tamaño y masa de los frutos en cada tratamiento. Posteriormente, se estimó la tasa de mortalidad de Melipona quadrifasciata expuesta a cuatro fungicidas (trifloxistrobina+tebuconazol, manganeso y zinc, hidróxido de cobre, Bacillus subtilis). La tasa de mortalidad de M. quadrifasciata en 24 horas de evaluación fue mayor en los tratamientos con hidróxido de cobre y trifloxistrobina+tebuconazol (75 y 50%, respectivamente). La tasa de mortalidad fue menor en los tratamientos con manganeso y zinc, Bacillus subtilis y el tratamiento de control. Los tratamientos con trifloxistrobina y tebuconazol redujeron la presencia de marcas de mordida y granos de polen en el estigma de las flores. Los frutos de los tratamientos control y con B. subtilis e hidróxido de cobre fueron más grandes y tuvieron mayor masa. Por lo tanto, un mayor número de aplicaciones de pesticidas en las plantas de tomate reducen las tasas de visitas de abejas en las flores y en consecuencia, la cantidad de granos de polen depositados en los estigmas afectando también la producción de los frutos., The use of agrochemicals is harmful to bees visiting agricultural crops, reducing production gains from pollination, but the effect of fungicides on these bees is not known. The objective of this study was to verify the effect of bee visitation influenced by different fungicides on the tomato crop and on the deposition of pollen grains on the stigma, number of seeds, mass and fruit size. The experiment was conducted with 10 treatments: (T1) control treatment, without application of agrochemicals; (T2 and T3) Bacillus subtilis in different application frequencies; (T4) copper hydroxide; (T5) B. subtilis and copper hydroxide; (T6) acibenzolar-S-methyl; (T7) (trifloxystrobin+tebuconazole) and B. subtilis; (T8) copper hydroxide+Mancozeb; (T9) propineb+(trifloxystrobin+ tebuconazole); (T10) (trifloxystrobin+tebuconazole)+B. subtilis+copper hydroxide. The presence of the pollination mark on the flower, the pollen load of the stigmas, the number of seeds per fruit, and the size and mass of the fruits were determined in each treatment. Subsequently, the mortality rate of Melipona quadrifasciata (Hymenoptera, Apidae) exposed to four fungicides (trifloxystrobin+tebuconazole; manganese and zinc; copper hydroxide; Bacillus subtilis) was estimated. The mortality rate of M. quadrifasciata over 24 h of evaluation was higher in the treatments with copper hydroxide and trifloxystrobin+tebuconazole (75 and 50%, respectively). The mortality rate was lower in the treatments with manganese and zinc and Bacillus subtilis and in the control treatment. The treatments with trifloxystrobin+tebuconazole reduced the presence of bite marks on the flowers and of pollen grains on the flower stigma. The fruits of the control treatments and treatments with B. subtilis and copper hydroxide were larger and had greater mass, as compared to other agrochemicals. Thus, a higher number of pesticide applications on the tomatoes reduced bee visitation rates to the flowers and, consequently, reduced the amount of pollen grains deposited on the stigmas, also reducing the fruit production., Bibliografía: páginas 434-435

Estudos sobre estoque de nutrientes na serapilheira são importantes para consolidar informações sobre a ciclagem de nutrientes e produtividade em ecossistemas florestais. O objetivo deste estudo foi caracterizar o estoque de nutrientes na serapilheira acumulada em quatro tipos de vegetação no Cerrado, no estado de Goiás. A coleta da serapilheira acumulada foi realizada de forma aleatória em quatro tipos de vegetação (Área de Preservação Permanente, Cerrado Sentido Restrito, povoamento com Eucalyptus e povoamento com Pinus), utilizando uma moldura com 25 cm x 25 cm (0,0625 m2) de dimensão. A serapilheira foi triada nas frações folhas/acículas, galhos, cascas, materiais reprodutivos e miscelânea, com posterior determinação de massa seca, teor e estoque de nutrientes. O maior estoque de nutrientes foi encontrado na serapilheira acumulada na Área de Preservação Permanente, onde o cálcio é o elemento acumulado em maior quantidade quando comparado aos demais macronutrientes. Na serapilheira acumulada nos demais tipos de vegetação, o nitrogênio esteve estocado em maior quantidade. O nitrogênio é um nutriente de suma importância no metabolismo da planta, sendo essencial à fotossíntese. Para os micronutrientes, o elemento mais acumulado foi o manganês, na serapilheira produzida em todos os tipos de vegetação. O manganês tem função importante para as plantas, pois atua no desenvolvimento das raízes e na síntese de clorofila. Os elementos estocados em menores quantidades são o fósforo e enxofre. O gradiente de magnitude de estoque dos nutrientes variou de acordo com a fração da serapilheira e com o tipo de vegetação, não apresentado um padrão.

Em razão da escassez de informações sobre adubação em acácia-negra, no presente estudo, objetivou-se avaliar o crescimento de plantas de acácia-negra em função de diferentes níveis de adubação com nitrogênio, fósforo e potássio, após seis anos da implantação. O delineamento utilizado foi de blocos ao acaso, com distribuição trifatorial (doses de fertilizantes). Avaliou-se a altura total (m), diâmetro a altura do peito (DAP) (cm) e volume de madeira com casca (m³ ha-1). A acácia-negra apresentou resposta positiva e significativa, de crescimento às adubações com N e P (interação) e ausência de resposta ao K. Para a obtenção do máximo crescimento da acácia-negra, para a condição edafoclimática estudada, deve-se utilizar a dose máxima de nitrogênio (40,0 kg ha-1 de N) e 78,9 kg ha-1 de fósforo, não sendo necessária a adição de potássio via fertilizantes. Due to the lack of information about Black-wattle fertilization, this study evaluated black-wattle plants growth in response to different fertilization levels of nitrogen, phosphorus and potassium six years after implantation. The statistical design used was a randomized blocks with trifatorial distribution. Total height (m), diameter at breast height (DBH) (cm) and stem volume with bark (m³ ha-1) were evaluated. Black-wattle showed a positive and significant growth response to N and P (interaction) fertilizations and absence for K. m To obtain the maximum development of black-wattle, for the soil and climate condition studied, it is required the use of the maximum dose of nitrogen (40.0 kg ha-1 N) and 78.9 kg ha-1 phosphorus, not requiring the addition of potassium.

This study had as objective to quantify biomass and nutrients, in an 18 months Eucalyptus urograndis stand in southeastern mountain range, Piratini-RS. Twenty-four (24) plots (15.0 m x 22.5 m) were allocated; after that, one tree (with diameter at breast height) was felled in each plot. The tree was fractionated in the following fractions of above ground biomass: wood, bark, branches and leaves. Total biomass was 18.5 Mg ha-1, being the wood the fraction with highest biomass (37%), followed by branches (34.2%), leaves (21.3%) and bark (7.6%). Leaves showed highest nutrients concentrations, being statistically superior to other fractions (p N > K > Mg > P > S, and for micronutrients was Mn > Fe > B > Zn > Cu. Highest amount of nutrients is contained on leaves component, due to the highest nutrients concentration, excepted for Ca, Mg and Cu that are located in large quantities in the branches.Objetivou-se quantificar a biomassa e os nutrientes, em povoamentos de Eucalyptus urograndis, aos 18 meses de idade na serra do sudeste, Piratini-RS. Alocaram-se 24 parcelas de 15,0 m x 22,5 m, após abateu-se uma árvore em cada, sendo esta, a que possuía o diâmetro médio a altura do peito. A árvore foi fracionada nos seguintes componentes da biomassa acima do solo: madeira, casca, galhos e folhas. A biomassa total foi 18,5 Mg ha-1, sendo a madeira a fração que apresentou maior percentual (37,0 %), seguida pelos galhos (34,2 %), folhas (21,3%) e casca (7,6 %). As folhas apresentaram as maiores concentrações de nutrientes, sendo estatisticamente superior as demais frações (p N > K > Mg > P > S e Mn > Fe > B > Zn > Cu, para os micronutrientes. A maior quantidade de nutrientes estava contida no componente folhas, devido a sua maior concentração de nutrientes, com exceção ao Ca, Mg e Cu que estão alocados em maiores quantidades nos galhos.

Urban trees can influence from landscape factors to microclimatic, affecting human well-being. This study had as objective to characterize two different sectors in Goiânia, Goias, Brazil and to verify how urban trees influence the microclimate. Two different areas, 1 km long each one, in two avenues from the city (Goias Av. and Planicie Av.). In each area, a census from all trees was conducted and the following variables were measured: temperature (oC), relative humidity (%), wind speed (km/h) and light intensity (lux). Descriptive analysis with absolute and relative frequency of tree species, Mann-Whitney (95%) test for comparing abundance among species, T Test (95%) for microclimate variables comparison among full sun and shaded areas in each one of the avenues and the last procedures were a principal components analysis (PCA) and a correspondence analysis (CCA) to verify the influence of environmental variables between full light and shaded areas. In areas shaded by trees crowns, temperatures, light intensity and wind speed showed lower values than shaded areas, while relative humidity showed higher values in these environments than in places without trees. Urban trees contribute to microclimatic conditions improvement in urban landscapes, positively influencing human well-being in urban centers.

Este trabalho, realizado em um povoamento de Araucaria agustifolia de 27 anos de idade no município de Quedas do Iguaçu (PR), teve como objetivos: estimar a biomassa nos diferentes componentes das árvores, no sub-bosque e na serapilheira acumulada sobre o solo. A biomassa foi estimada por meio do ajuste de equações de regressão, com coleta de 21 árvores distribuídas em sete classes diamétricas, serapilheira e o sub-bosque com base em unidades amostrais de área conhecida. A biomassa total do povoamento foi de 241,92 Mg ha-1, sendo 82,2% de Araucaria angustifolia, 9,6% de sub-bosque e 8,2% de serapilheira. Considerando apenas a biomassa de Araucaria angustifolia, 198,62 Mg ha-1, madeira do tronco (51,5%), casca do tronco (14,7%), raiz (13,0%), galhos vivos (11,8%), grimpas (ramos aciculados) (8,6%) e galhos mortos (0,5%). A produção relativa de biomassa no componente madeira do tronco pode ser menor, quando comparado com outras espécies florestais, sobretudo por causa da elevada alocação no componente casca do tronco.

Os objetivos do trabalho foram quantificar e comparar a densidade e a biomassa de raízes finas (≤ 2,0 mm) na serapilheira e nas camadas de 0-10, 10-20, 20-30, 30-40 cm ao longo do perfil de solo, em um povoamento de Pinus taeda L., com 15 anos de idade, e em uma área de campo adjacente. A obtenção das amostras de raízes, foi realizada partindo da escavação de monolitos. As raízes foram separadas do solo por meio de lavagem e catação e, na sequência, foram distribuídas sobre uma folha de papel branca, em que, com o auxílio de uma câmera digital, foram obtidas imagens. Com o auxilio do software Image Tool for Windows version 3.00© as imagens foram processadas para quantificação do comprimento das raízes. Após, as raízes foram secas e, depois, pesadas para determinação da biomassa. A vegetação presente na área de campo apresenta uma densidade de raízes finas 234,28% maior que a área adjacente onde encontra-se o povoamento de Pinus taeda L.

A importância da serapilheira se dá pelo retorno da matéria orgânica acumulada e nutrientes para o solo, representando grande parte da restauração da fertilidade deste, sendo essencial para a manutenção da capacidade produtiva da área. Em sistemas consorciados, como o ILPF, a decomposição da matéria orgânica é uma forma de sinergismo e complementaridade que beneficia a ciclagem de nutrientes possibilitando maior eficiência para meios de produção. O objetivo desse trabalho foi avaliar a produção de biomassa nas estações seca e chuvosa da serapilheira de um plantio de Eucalyptus urograndis em sistema integrado de lavoura-pecuária-floresta (ILPF) aos 5 (cinco) anos de idade. O estudo foi realizado no município de Cachoeira Dourada, em um sistema integrado de lavoura-pecuária-floresta, na Fazenda Boa Vereda, ao sul do Estado de Goiás, GO, Brasil. Para a coleta de serapilheira acumulada foram utilizados quatro renques com dois tratamentos – um entre plantas e um entre linhas de eucalipto. Foram coletadas 50 amostras aleatoriamente nos renques, sendo 25 amostras entre plantas e 25 entre linhas. Para a coleta da serapilheira acumulada utilizou-se um gabarito de madeira com área de 0,0625 m2). Após secagem do material em estufa de circulação e renovação de ar por 72 horas a 65°C, foi separado em cada componente (folha, galho/casca, miscelânea) e obtido seu peso total. Os valores obtidos no estudo realizado foram: 11,16 Mg ha-1 no período chuvoso e 12,66 Mg ha-1 no período seco, com um incremento de 1,49 Mg ha-1 (13,43%) na biomassa total acumulada. As maiores quantidades absolutas foram da porção galho/casca, porém o maior incremento foi da porção miscelânea seguido da porção folha. Houve maior porcentagem de deposição da fração folha e miscelânea entre plantas e da fração galho/casca e miscelânea entre linhas. O período seco apresentou a maior acúmulo de biomassa, principalmente pelo percentual de biomassa acumulada da fração folhas e galho/casca.

Ion input via rainfall alone and after interception by the forest canopy, constitutes an important path of biochemical cycling, although few studies have provided information on the subject so far. The objective of this work is to quantify ion inputs, via rainfall, in the southwestern region of Rio Grande do Sul state, Brazil. Ten rain gauges were mounted in a field area. The quantification of stored water volume, along with sample collection for determination of nitrate, nitrite, ammonium, phosphorus, sulfur, chlorine, calcium, magnesium, potassium and sodium contents, was done fortnightly from September 2006 to August 2008. Local annual average precipitation in the relevant period was 1,588.3 mm. The concentration of chemical elements in rainwater was found to vary throughout, being inversely correlated with the increase in rainfall, while potassium, ammonium, phosphate, sulfate, chloride and sodium were found to have a significant mutual correlation (p

There are few studies on the effects of fire on the seasonal semideciduous forest of the Cerrado region. This study aimed to assess the effect of fire on Semideciduous forest fragments located in the Altamiro Moura Pacheco State Park (AMPSP). The study area is located in the central state of Goias. A total of 10 plots (50 x 20 m; 1,000 m 2 ) were drawn in the remaining forests seeking to portray two areas: area which underwent forest fire (burned area; B) and unburned area (unburned; UB). A total of 771 individuals with DBH (≥ 5 cm) were identified. A total of 303 individuals were recorded in the burned area (B), comprising 28 families, 41 genera and 47 species, while the unburned area (UB) had 468 individuals comprising 25 families, 43 genera and 50 species. The species Anadenanthera colubrina (Vell.) Brenan, Emmotum nitens (Benth.), Zanthoxylum rhoifolium Lam, Tapirira guianensis Aubl., Myracrodruon urundeuva Allemao and Luehea candicans Mart. had the highest Importance Value Index (IVI) values and occur in both areas. The percentage of dead trees differed between the areas, where the burned area had a mortality of 12.69% and the unburned area of 7.29% in regards to the number of individuals. Density per plot was the only parameter that differed between the areas, where the burned area (B) had the lowest values. The fire affected all diameter classes, demonstrating the fragility of this vegetation type in regards to fire. The fire had a greater effect on trees in the smaller diameter classes, reducing the frequency of individuals in the burned area and changing height distribution, which may have favored the establishment of lianas and invasive species.

A diversificada e importante aplicação do lenho das plantações de eucalipto de rápido crescimento exige a análise do efeito dos fertilizantes minerais na qualidade do lenho. Dessa forma, objetivou-se, neste trabalho, avaliar as características anatômicas e a densidade aparente do lenho de árvores de Eucalyptus grandis, plantadas no espaçamento 3m x 2m e fertilizadas com potássio e sódio (no plantio, no 6º e no 12° mês). Foram selecionadas 15 árvores (5 árvores/tratamento) com 6 anos das quais foram cortadas amostras do lenho a 1,3 m de altura (DAP), para a análise das características anatômicas (fibras e vasos) e física (densidade aparente). Os resultados apontaram que as árvores de eucalipto que receberam aplicação de fertilizantes minerais não sofreram alterações significativas na densidade aparente média do lenho, com modelos dos perfis radiais comuns nos três tratamentos, caracterizados pelo aumento dos valores da região próxima à medula em direção à casca. A fertilização mineral influenciou as características anatômicas do lenho das árvores de eucalipto: o tratamento com sódio foi responsável pela diminuição na espessura da parede e pelo aumento no diâmetro do lume; no tratamento com potássio foram detectados vasos de maior diâmetro tangencial. The diverse and important use of wood from fast growth eucalyptus plantations requires the analysis of the effect of mineral fertilizers on wood quality. The objective of this study was to evaluate the anatomical characteristics and wood density from Eucalyptus grandis trees (3 m x 2 m spacing) fertilized with potassium and sodium (at planting, 6 th and 12th month). Fifteen (15) 6 years old eucalyptus trees were selected (5 trees/treatment), cut and wood samples at DBH (1,3 m) were taken for anatomical characteristics (fiber and vessels) and wood density analysis. Results showed that eucalyptus trees treated with mineral fertilizers did not show significant alteration in average wood density, with radial profile model common to all three treatments, characterized by a values increase in the region next to the pith, toward to bark. Mineral fertilization influenced wood anatomical characteristics: treatment with sodium was characterized by thinner walls and lumen larger diameter; in treatment with potassium, larger vessels were detected.

Este estudo foi realizado em um sistema de produção integrado lavoura-pecuária-floresta no município de Cachoeira Dourada, Goiás, Brasil. A pesquisa colabora para um melhor entendimento da interação planta-ambiente, esta foi realizada com o objetivo de analisar a entrada de luz em dois períodos diferentes (estação seca e chuvosa). Para a coleta da Densidade de Fluxo de Fótons (DFF) (µmol.m-2.s-1) foi utilizado dois sensores de quanta LI-250 A, Li-cor Inc., USA, na faixa fotossinteticamente ativa. A coleta foi realizada de hora em hora, com início às 9h45min e término às 17h45min. Coletou-se o DFF controle - a pleno sol, e as demais coletas foram realizadas em quatro pontos: (1- no centro do renque de árvores, 2 - a 5m do renque, 3 - a 10m do renque e 4- a 15m do renque), sendo que em cada ponto se obteve mais 4 repetições. De acordo com os resultados obtidos se verificou que houve diferenças entre os pontos escolhidos, sendo o ponto 10 e 15 metros com maior recebimento de faixa de Radiação Fotossinteticamente Ativa (RFA). Portanto, o sistema Integrado Lavoura-Pecuária-Floresta (ILPF) não reduziu a Densidade de Fluxo de Fótons (DFF). A maior DFF foi verificada no período de seca, porém, a maior variação da DFF foi encontrada no período chuvoso. Quanto maior à distância em relação aos renques, com eucaliptos, maior à incidência de radiação solar.
