O Sistema Plantio Direto (SPD) tem sido adotado em grandes culturas econômicas as quais são quase totalmente mecanizadas nos dias atuais, entretanto, para o ramo das hortaliças tal sistema ainda tem sido pouco utilizado e um dos fatores tem sido a falta de pesquisas especificas na área. Em razão disso, o presente trabalho teve por objetivo avaliar os atributos físicos de um Argissolo Vermelho Amarelo em implantação de SPD cultivado com hortaliças e adubos verdes. O experimento foi desenvolvido em área experimental da Faculdade de Ciências Agrárias e Tecnológicas (FCAT/UNESP), sediada no município de Dracena - SP. Foram realizados dois cultivos de hortaliças em rotação de cultura com coberturas vegetais durante 2 anos. O experimento foi conduzido em duas épocas, uma no outono/inverno (Tremoço, Mix, Aveia, Repolho e Alface) e outro na primavera/verão (Estilosantes, Mix, Milheto e Pepino), instalados em delineamento de blocos casualizados com parcela subdividida e quatro repetições. Foram realizadas avaliações dos seguintes atributos físicos: Distribuição e estabilidade de agregados; Porosidade e Densidade do solo; Infiltração de água no solo; Resistência mecânica a penetração e umidade do solo. Distribuição e estabilidade de agregados em água – houve um aumento no tamanho dos agregados tendendo assim a uma possível melhora na estrutura do solo. Porosidade do solo – em consequência do revolvimento do solo houve aumento na macroporosidade, e mesmo o SPD também se observa um pequeno aumento. Densidade do solo (DS) – o SPD se mostrou com maiores valores de DS previsto pelo não revolvimento do solo. Infiltração de água no solo – os valores médios decresceram significativamente. Resistência do solo à penetração – o solo da área estudada já possuía valores positivos no início das coletas, pois os valores médios encontrados estão abaixo de 2Mpa. Os dados obtidos no presente trabalho se mostram consistentes e positivos, sendo muito interessante a continuidade do estudo do sistema em formação. The preservation of agricultural soils through the adoption of adequate systems of use and management is essential for their conservation, contributing to the maintenance of crop productivity. The no-tillage system (NTS) has been widely applied in major economic crops which are almost completely mechanized nowadays, however, for the field of vegetables such system has still been a little used and one of the factors has been the lack of specific research in the area. For this reason, this study aimed to evaluate the physical attributes of a Ultisol under NTS implantation cultivated with vegetables and green manures. The experiment was developed in the experimental area of the College of Agricultural and Technological Sciences/São Paulo State University (FCAT/UNESP), headquartered in Dracena-SP. Two vegetable crops were grown in crop rotation with vegetable coverings for 2 years. The experiment was carried out in two seasons, one in autumn/winter (lupine, mix, oats, cabbage and lettuce) and another in spring/summer (Styling, Mix, millet and cucumber), installed in a randomized block design with split plot and four reps. Assessments of the following physical attributes were carried out: Distribution and stability of aggregates; Soil Porosity and Density; Soil water infiltration; Mechanical resistance to penetration and soil moisture. Distribution and stability of aggregates in water - there was a increase in aggregate size thus tending to an improvement in soil structure. Soil porosity - as a result of soil disturbance there was an increase in macroporosity, and even the SPD is also observed a slight increase. Soil density - the SPD shows the highest values of DS predicted by the non-revolving soil. Soil water infiltration - mean values decreased patients. Soil resistance to penetration - the soil in the studied area already had positive values at the beginning of the collections, as the mean values found are below 2Mpa. The data collected in this work are consistent and positive, and it is very interesting to continue the study of the system in formation.

We aim to determine the growth performance of two 20-year-old silvopastoral systems comprising two timber trees, a palm tree), a short-lived perennial shrub, a forage and livestock; and to investigate fibre features and certain physical and mechanical properties of two timber trees (Myracrodruon urundeuva and Peltophorum dubium) in two plantation systems. The first system is called MP with two timber trees and the second one is called MPS with two timbers and a palm tree. The studied systems showed that it was possible to successfully combine fast-growing species, animals, forage and woody tree species, with a production cycle of more than 50 years of different goods and services (e.g., ornamentals, palm hearts, landscaping, fruits, seeds, bee pasture, meat, and wood). The height, diameter and volume for M. urundeuva trees in the MP system were greater than in the MPS system, whereas no difference between the systems was observed for P. dubium. By comparison, the growth and volume in P. dubium were greater than in M. urundeuva. For wood properties, it was shown that both systems can be used successfully, but the MPS system performed better than the MP system, in the aim of wood production of high mechanical strength and calorific value. In addition, the MPS intercropping system can yield more goods and services than the MP system, both systems bring returns with short-term (bean seed, forage, pasture), medium-term (forage, palm products, pasture, wood), and long-term (wood) financial returns. Nuestro objetivo fue determinar el desempeño de dos sistemas silvopastoriles de 20 años que comprenden dos árboles maderables, una palma, un arbusto de hoja perenne de vida corta, un forraje y ganado; e investigar las características de la fibra y algunas propiedades físicas, mecánicas y energéticas de Myracrodruon urundeuva y Peltophorum dubium. Sistema 1 se llama MP con dos árboles maderables y Sistema 2 se llama MPS con dos árboles maderables y una palma. Los sistemas mostraron que era posible combinar con éxito especies de rápido crecimiento, animales, forrajes y especies de árboles leñosos, con un ciclo de producción de más de 50 años de diferentes bienes y servicios (p. ej., ornamentales, palmito, jardinería, frutas, semillas, pasto de abejas, carne y madera). La altura, diámetro y volumen de los árboles de M. urundeuva en el sistema MP fueron mayores que en el sistema MPS, mientras que no se observaron diferencias entre los sistemas para P. dubium. En comparación, el crecimiento y el volumen en P. dubium fueron mayores que en M. urundeuva. En cuanto a las propiedades de la madera, se demostró que ambos sistemas se pueden utilizar con éxito, pero el sistema MPS presentó mejor desempeño que el sistema MP, en el objetivo de producir madera con alta resistencia mecánica y poder calorífico. Además, el sistema de consorcio MPS puede generar más bienes y servicios que el sistema MP, ambos sistemas traen retornos a corto plazo (semilla de frijol, forrajes, pastos), medio plazo (forrajes, palma, pastos, madera) y retornos financieros a largo plazo. instrumentos (madera). Objetivamos determinar o desempenho de dois sistemas silvipastoris com 20 anos de idade compreendendo duas espécies madeireiras, uma palmeira, um arbusto perene de vida curta, uma forrageira e gado; e investigar características das fibras e algumas propriedades físicas, mecânicas e energéticas de Myracrodruon urundeuva e Peltophorum dubium. O primeiro sistema é denominado MP com duas árvores madeireiras e o segundo é denominado MPS com duas árvores madeireiras e uma palmeira. Os sistemas estudados mostraram que foi possível combinar com sucesso espécies de rápido crescimento, animais, forrageiras e espécies arbóreas lenhosas, com um ciclo de produção de mais de 50 anos de diferentes bens e serviços (por exemplo, ornamentais, palmitos, paisagismo, frutas, sementes, pasto apícola, carne e madeira). A altura, diâmetro e volume das árvores de M. urundeuva no sistema MP foram maiores do que no sistema MPS, enquanto nenhuma diferença entre os sistemas foi observada para P. dubium. Em comparação, o crescimento e o volume em P. dubium foram maiores do que em M. urundeuva. Para as propriedades da madeira, foi demonstrado que ambos os sistemas podem ser usados com sucesso, mas o sistema MPS apresentou melhor desempenho do que o sistema MP, no objetivo de produção de madeira de alta resistência mecânica e poder calorífico. Além disso, o sistema consorciado MPS pode render mais bens e serviços do que o sistema MP, ambos os sistemas trazem retornos de curto prazo (semente de feijão, forragem, pasto), médio prazo (forragem, palmeira, pasto, madeira) e retornos financeiros de longo prazo (madeira).

Cachaça is a typical Brazilian spirit of significant economic and social relevance. The spirit may contain organic and inorganic contaminants that impair its quality, such as ethyl carbamate (EC), which is potentially carcinogenic. The study of factors that cause EC incidence is extremely important to produce cachaça with good physicochemical and sensory quality and for public health reasons. Therefore, this study aimed to analyze and quantify nitrogen (N) in sugarcane juice and correlate it with the EC levels, with copper (Cu) as precursor, in cachaça from stills, produced from the sugar of three different sugarcane varieties (RB857515, RB966928 and RB855453). We used the plantation systems without fertilization and with organic and conventional fertilization. The EC and Cu levels were below the legislation threshold and the N levels were correlated with EC formation in different planting systems.

Arrowroot is a plant originated in Latin America that has aroused interest in the food industry due to its high starch content, with differentiated characteristics and high commercial value. However, information on the management of arrowroot are scarce, precluding its commercial competition with other similar species, being necessary further studies with the crop. Thus, the objective of the present study was to characterize extracted starch from arrowroot grown under different agronomic management. Three agronomic factors were studied: planting systems (PS), forms of water management (WM) and planting density (PD). The experimental analyses were performed in a completely randomized design (CRD) with three replicates, being evaluated the extraction yield, percent composition, quantity of starch, pH, titratable acidity, swelling power, solubility and electron microscopy analysis. In general, the analyzed extracted starches deriving from different agronomic treatments have low crude fiber, besides typical characteristics of arrowroot extracted starch such as texture, color, shape and size of granules, without any other apparent particle than the starch itself, indicating extraction efficiency. However, the planting density may have contributed to influence some parameters of the chemical composition of the extracted starch, such as the content of starch, ash, ether extract, protein and carbohydrate fraction.

Introduction. Arracacha (Arracacia xanthorrhiza Bancroft) a promising crop due to its nutritional and gastronomic relevance. Population density is an agronomic practice that increases water and radiation use efficiencies, maximizes the yield, and crop profitability. However, the selection of the optimal population density based on physiological, agronomic, and economic criteria for arracacha has not been studied. Objective. To describe the effect of different population densities on the physiology, yield, and profitability of arracacha. Materials and methods. The experiment was conducted in Cajamarca, Colombia in 2019. There, the soil water potential, relative chlorophyll content, photosynthesis, stomatal conductance, water use efficiency, leaf temperature depression, photosynthetic reflectance index, leaf area index, the fraction of light interception, light extinction coefficient, cracking index, yield, and profitability were evaluated. Results. The results showed that high population densities did not generate water deficit because there were no significant differences for the soil water potential, leaf temperature depression, and photosynthetic reflectance index. Furthermore, no nutritional deficiencies were evidenced because the relative chlorophyll content (

The increase in the demand for almonds, the development of novel self-fertile and late-flowering varieties, and the establishment of plantations in new irrigated areas have led to significant progress in the productive techniques of almond tree cultivation. One of the most important has been the increase in planting density, due to the development of dwarfing rootstocks. This paper presents a comparison between two training systems with &lsquo, Soleta&rsquo, almond cultivar: a super high density (SHD) system using Rootpac-20 dwarfing rootstock versus an open-center training system using GF-677 rootstock. To this end, several parameters related to chlorophyll content (fluorescence and SPAD) and light interception (from photosynthetically active radiation (PAR) measurements) were monitored throughout two vegetative cycles, and other productive conditions (flowering, fruit set and production) were tracked at specific times of the cycle. The open-center system resulted in higher PAR interception than the SHD system, but also in the presence of poorly illuminated fractions of the canopy. Differences were observed between both systems in terms of average fruit weight and yield per canopy volume. Lower yields were obtained in SHD system than in open-center, which may be significantly increased by adapting the inter-row spacing. However, the degree of efficiency in the use of resources or productive inputs, such as irrigation, was favorable to the new SHD training system, so its potential to become a reference system in modern plantations (using over-the-row harvesters similar to those used for vine and olive trees) seems promising.

In this study, it was aimed to compare 6 various commercial strawberry cultivars (‘Kabarla’, ‘Sweet Ann’, ‘Rubygem’, ‘Festival’, ‘Amiga’, ‘Florida Fortuna’) based on their some fruit quality characteristics in Diyarbakır region (south-eastern) of Turkey. The frigo and fresh plants of 6 strawberry cultivars were compared during the 2015-2016 growing year period. Some important fruit quality characteristics such as total soluble solid content (TSS%), titratable acidity, fruit colour, fruit firmness (Lb) were compared and some phenological characteristics such as first blooming, 50% flowering and full flowering time were also compared. Most of the cultivars have advantage when they are cultivated with frigo plant type in terms of first flowering date except ‘Festival’ and ‘Sweet Ann’. Most quality parameters were affected by cultivar, plant type and their interaction such as TSS, TTA and, L* value. When using the fresh plant type there are more advantages for certain quality parameters (acidity % and TSS %) and brightness (L*). The other parameters were observed better for the frigo plant type. ‘Sweet Ann’ was detected the most preferable one among the experimental cultivars for Diyarbakır ecologic conditions of the eastern part of Turkey. © 2019 International Society for Horticultural Science.

The study was conducted in a Wiregrass Model Tunnel House to evaluate the response of two sweetpotato cultivars (“Carver” and “TU-1892”) and two different planting methods (Conventional and Trellised) at S & B Farm in Eufaula AL., during the summer of 2015. Sweetpotato varieties were the main plots and planting methods were the subplots, each treatment combination was replicated four times. Results indicated that there were significant interactions between sweetpotato varieties and planting methods for US#1, Canners, and total marketable yield. There were also significant differences between varieties and planting methods for Canners and between varieties and total marketable yield. The results indicated that the response of sweetpotatoes under tunnel house conditions maybe varietal related, and influenced by high ambient temperature prevalent in tunnel houses during the summer months. Further studies will be required to test other varieties of sweetpotatoes and to evaluate impact of heat stress on root production.

Soybean has been the main crop used in rotation with irrigated rice in Rio Grande do Sul. However, soybean cultivation in lowland represents a high-risk activity due to stresses that generally occur in this environment. These stresses may significantly reduce growth and development of soybean plants by limiting important physiological processes such as photosynthesis and biological nitrogen fixation. In view of the above, the thesis work aimed to determine the influence of different cropping and irrigation systems on root growth, nodulation, oxidative stress, photosynthesis, soil water holding capacity, water use efficiency and grain yield of soybean in lowlands. Two experiments were carried out under field conditions and one under greenhouse conditions in the Várzea Experimental area of the Federal University of Santa Maria, RS, during 2014/15 and 2015/16 growing seasons. For the burndown timing of ryegrass experiment, applications were carried out between 20 and 90 days before soybean planting on raised seedbeds. The experiment 1 involving cropping systems and irrigation consisted of combinations between raised seedbeds flat planting with or without the practice of irrigation. The experiment 2, was carried out under greenhouse condictions and was characterized by the implementation of 10 days water deficit during V6 (six expanded trifoliate), R2 (full flowering) and R5 (grain filling) growth stages. Based on the main results, it was observed that desiccation and sowing intervals of soybean less than 60 days or quantities of ryegrass straw remaining on the soil surface higher than 1000 kg ha-1 significantly increase soil moisture retention at the sowing time. Growing soybeans using raised seedbeds increase crop yield and reduce irrigation water use when compared to flat-planting of soybean in a rice-soybean rotation. Water shortage during the grain filling period significantly reduces grain yield of soybean in lowlands. A soja tem sido a principal cultura utilizada em rotação com o arroz irrigado no Rio Grande do Sul. No entanto, o cultivo da soja em terras baixas constitue-se em uma atividade de alto risco devido aos estresses que geralmente atuam neste ambiente. Estes estresses podem reduzir significativamente o crescimento e desenvolvimento das plantas de soja através da limitação de processos fisiológicos importantes como por exemplo, a fotossíntese e a fixação biológica de nitrogênio. Em vista do exposto, o trabalho de tese teve como objetivo determinar a influência de diferentes sistemas de implantação e de irrigação no crescimento do sistema radicular, nodulação, estresse oxidativo, fotossíntese, armazenamento de água no solo, eficiência do uso de água e rendimento de grãos de soja em terras baixas. Foram realizados dois experimentos em condições de campo e um em casa de vegetação na área Experimental de Várzea da Universidade Federal de Santa Maria, RS, durante os anos agrícolas de 2014/15 e de 2015/16. O experimento1 consistiu de épocas de dessecação do azevém, as quais foram realizadas entre 20 e 90 dias antes da semeadura da soja em camalhões. O experimento envolvendo sistemas de implantação e irrigação constituiu-se das combinações entre camalhões e sem camalhões com ou sem irrigação suplementar. O experimento 2 foi realizado em casa de vegetação e caracterizou-se pela implementação de 10 dias de deficit hídrico nos estádios fenólóficos V6 (seis trifólios expandidos), R2 (florescimento pleno) e R5 (enchimento de grãos). Com base nos principais resultados, observou-se que intervalos de dessecação e semeadura da soja menores de 60 dias ou quantidades de palha de azevém remanescente na superfície do solo superiores a 1000 kg ha-1 aumentam signicativamente a retenção de umidade no momento de semeadura. O uso de camalhões para o cultivo da soja aumenta o rendimento de grãos e reduz o uso de água para irrigação comparado ao sistema sem camalhões. A deficiência hídrica durante o período de enchimento de grãos reduz significativamente o rendimento de grãos de soja em terras baixas.

O experimento foi dividido em três etapas, sendo que em duas foram avaliadas a qualidade silvicultural e as variáveis dendrométricas (diâmetro do colo, diâmetro à altura do peito e altura da planta). Essas etapas ocorreram nas cidades de Bocaiúva, MG, onde se conduziu o experimento sob quatro tratamentos com cinco repetições, em que cada repetição era constituída por 60 mudas do híbrido Eucalyptus urophylla x Eucalypytus camaldulensis. A segunda etapa foi realizada em Telêmaco Borba, PR, onde se implantaram dois tratamentos com oito repetições, constituídos de 60 mudas de Pinus taeda e a última etapa, referente ao estudo econômico do plantio de Eucalyptus urophylla x Eucalyptus grandis em dois espaçamentos 3 × 1 m e 3 × 1,5 m utilizando o conjunto plantador, ocorreu em Lençóis Paulista, SP. Para as análises de comparações entre os tratamentos da qualidade silvicultural e as variáveis dendrométricas foi utilizado o teste LSMeans, do procedimento Genmod, por meio do software estatístico SAS – Statistical Analysis System. Os custos das máquinas foram calculados de acordo com a metodologia desenvolvida pela European COST Action, resultando em duas unidades: Euro por hora efetiva da máquina (€ h-1) e euro por muda (€ muda-1). As avaliações silviculturais da qualidade dos plantios evidenciaram que nas variáveis de substrato totalmente exposto e plantio inclinado não houve diferenças significativas nos sistemas de plantio mecanizado e manual de Eucalyptus urophylla x Eucalyptus camaldulensis e para Pinus taeda as análises não apresentaram diferença estatística para as variáveis de substrato parcialmente exposto, substrato totalmente exposto e plantio inclinado para os dois sistemas de plantio. As variáveis dendrométricas de diâmetro à altura do peito e altura de plantas obtiveram maior desenvolvimento aos doze meses após o plantio, no sistema de plantio mecanizado de Eucalyptus urophylla x Eucalyptus camaldulensi. Enquanto que para o plantio de Pinus taeda os maiores desenvolvimentos em diâmetro de colo das plantas foram observados no sistema manual aos doze meses após o plantio. A avaliação econômica teve como resultado que o maior espaçamento, 3 × 1,5 m, apresentou 11,9 % a mais no custo final em relação ao menor espaçamento de 3 × 1 m. The study evaluated the quality of planting in two different systems, mechanized using the Bracke Forest P11.a device and manual (conventional), besides to present an economic vision for the first experience of using this device in Brazil. The experiment was divided into three stages, and two were evaluated silvicultural quality and dendrometric variables (stem diameter, diameter at breast height and plant height). These stages occurred in the cities of Bocaiúva, MG, where the experiment was conducted under four treatments with five repetitions, in each repetition consisted of 60 seedlings of the hybrid Eucalyptus urophylla x Eucalypytus camaldulensis. The second stage was executed in Telemaco Borba - PR where implanted two treatments with eight replications, made up of 60 seedlings of Pinus taeda and the last stage, referring to the economic study of the planting of Eucalyptus urophylla x Eucalypytus grandis in two spacings 3 × 1 m 3 × 1.5 m using the planter group, occurred in Lençóis Paulista - SP. For the analysis of comparisons between treatments silvicultural quality and dendrometric variables was used LSMeans test, the Genmod procedure, using the statistical software SAS - Statistical Analysis System. The operation costs were calculated according to the methodology developed by the European COST Action, resulting in two units: Euro per hour effective machine (€ h-1) and euro for seedlings (€ seedlings-1). The evaluations of the silvicultural quality of the plantings resulted that the variables fully exposed substrate and the inclined planting there were no significant differences in the mechanized and manual planting systems of the Eucalyptus urophylla x Eucalypytus camaldulensis and the Pinus taeda analyzes showed no statistical difference in the variables of partially exposed substrate, fully exposed substrate and planting inclined to the two planting systems. The dendrometric variables of the diameter at breast height and plant height had higher development at the twelve months after planting in the mechanized planting system of the Eucalyptus urophylla x Eucalypytus camaldulensi. While for the Pinus taeda planting the higher developments in the stems diameters of the plants were observed in the manual planting system at the twelve months after planting. The economic evaluation had as resulted that in the wider spacing, 3 × 1.5 m, showed 11.9% more in the final cost in relation to the narrower spacing of 3 × 1 m.

No. of bitstreams: 0 Previous issue date: 2012-03-01 The use and inadequate exploitation of natural resources is restricting the occurrence of aroeira (Myracrodruon urundeuva F.F. & M.F. Allemão), which now is on the FAO list of endangered species. This exploitation causes a decrease in the genetic base of M. urundeuva populations, which makes it difficult to find genotypes with stability and adaptability to different growing conditions. This study aimed at estimating the genetic variation and productivity, stability and adaptability of progenies of a M. urundeuva natural population, from the Ecological Station of Paulo de Faria-SP, under different planting systems. DBH (diameter at breast height) was evaluated in four progeny tests of M. urundeuva: i) planted with Anandenanthera falcata and Guazuma ulmifolia (TP-AMA); ii) single (TP-ASO); iii) planted with annual crops (TP-SAF) and iv) planted with Corymbia citriodora (TP-EUCA), installed in Selvíria-MS. The experimental design consisted of complete randomized blocks with three replications and a variable number of plants per plot in each of the four planting systems. From the joint analysis of the planting systems studied, it was found that: i) there were variations among planting systems particularly in TP-SAF; ii) only in TP-EUCA it was possible to detect variations among the progenies; iii) the effects of the genotype x environment interaction were not significant. Thereby, the harmonic mean of genotypic values (MHVG), the relative performance of genotypic values from the mean of each site (PRVG) and the harmonic mean of the relative performance of genotypic values (MHPRVG) for DBH showed, respectively: progenies with greater stability, adaptability, and stability and simultaneous adaptability within different planting systems. The use of these selection criteria provided a more refined selection of the best progenies of M. urundeuva under the different planting systems studied.

Visando estudar um sistema de cultivo para o consórcio do milho (Zea mays L.) com feijão (Phaseolus vulgaris L.) e milho com o caupi (Vigna unguiculata (L.) Walp), foram conduzidos experimentos durante os anos de 1995 e 1996, em Rio Branco, Acre. Quatro diferentes arranjos (uma, três, cinco e sete fileiras de feijão ou caupi para uma fileira de milho) foram testados no delineamento de blocos ao acaso com quatro repetições. A produtividade do feijão e do caupi, no arranjo de linhas 1:1, foi significativamente inferior aos demais, evidenciando que as leguminosas foram afetadas pela competição com milho. A produtividade do milho decresceu linearmente de acordo com o arranjo, devido as menores populações de plantas utilizadas. O sistema consorciado mais promissor, demonstrado pela produção equivalente, foi o arranjo composto por uma fileira de milho para três fileiras das leguminosas. To study the arrangement of mixtures of maize (Zea mays L.) with beans (Phaseolus vulgaris L.) or cowpea (Vigna unguiculata (L.) Walp), mixed cropping experiments were planted in 1995 and 1996, in Rio Branco, Acre. Four different arrangements (one, three, five, seven rows of beans or cowpeatone row maize) were tested in a randomized block design with four replications. The productivity of the beans and the cowpea in the 1:1 arrangement proved to be significantly inferior to the others, showing that the legumes were effected by the competition with the maize. The productivity of the maize decreased linearly in accordance with the arrangement owing to lower population densities. The most promising mixture, demonstrated by equivalent productivity, was composed of a row of maize to three rows of legumes.

In this study three strawberry cultivars (Dorit, Douglas and Cruz) were tested on different growing media in walk-in tunnel sack culture during 1994-95 growing season at the Alata Horticultural Research Institute. The main purpose of the experiment was to compare one year used and fresh growing media of peat+sand and sand+FYM. However to the sand+FYM used media, some FYM was added before its second year usage. All the media were solarized. Two types of planting system, summer planting (SP) and fresh runners rooted in pots (FRRP) in early summer months, were used and all the plants were planted at the beginning of August 1994. In the experiments the effects of growing media and planting system on precocity, yield and quality were investigated. According to the experimental results, the highest yields were obtained with 'Douglas' (753.92 g/plant) and 'Dorit' (684.40 g/plant). The yield of solarized newly prepared peat+sand media was 838.44 g/plant. It is followed by solarized newly prepared and reused sand + FYM media (701.28-710.32 g/plant, respectively). Both SP (721.80 g/plant) and FRRP (676.88 g/plant) were found to be high yielding systems. The first fruits were harvested on 3 November 1994 from 'Dorit'. The earliest fruits were produced by the FRRP planting system. The mean fruit size of 'Dorit' and 'Douglas' were superior to 'Cruz'. The fruits were larger in all growing media and with the summer plantings. The highest soluble solid content and sweetest fruit was produced by 'Dorit'.

Allemão), which now is on the FAO list of endangered species. This exploitation causes a decrease in the genetic base of M. urundeuva populations, which makes it difficult to find genotypes with stability and adaptability to different growing conditions. This study aimed at estimating the genetic variation and productivity, stability and adaptability of progenies of a M. urundeuva natural population, from the Ecological Station of Paulo de Faria-SP, under different planting systems. DBH (diameter at breast height) was evaluated in four progeny tests of M. urundeuva: i) planted with Anandenanthera falcata and Guazuma ulmifolia (TP-AMA); ii) single (TP-ASO); iii) planted with annual crops (TP-SAF) and iv) planted with Corymbia citriodora (TP-EUCA), installed in Selvíria-MS. The experimental design consisted of complete randomized blocks with three replications and a variable number of plants per plot in each of the four planting systems. From the joint analysis of the planting systems studied, it was found that: i) there were variations among planting systems particularly in TP-SAF; ii) only in TP-EUCA it was possible to detect variations among the progenies; iii) the effects of the genotype x environment interaction were not significant. Thereby, the harmonic mean of genotypic values (MHVG), the relative performance of genotypic values from the mean of each site (PRVG) and the harmonic mean of the relative performance of genotypic values (MHPRVG) for DBH showed, respectively: progenies with greater stability, adaptability, and stability and simultaneous adaptability within different planting systems. The use of these selection criteria provided a more refined selection of the best progenies of M. urundeuva under the different planting systems studied.
