Extensive cattle ranching had been the most common farming practice in northwestern Paraná State (Brazil), where soils originate from the Caiuá Sandstone. But this reality is changing with the growing cultivation of grain crops, especially soybeans. This study aimed to evaluate different soybean cropping systems in terms of yield components, plant dry matter, and soil chemical properties. The soil is classified as a dystrophic sandy Red Argisol, which derived from the Caiuá Sandstone, in northwestern Paraná State (Brazil). The experiment was carried out in the city of Umuarama (PR), Brazil, under a no-till system for three years. Treatments consisted of the following crop rotation systems: T1: congo grass/soybeans, congo grass/soybeans, congo grass/soybeans; T2: black oats + rye/soybeans, black oats + radish/grain sorghum, black oats + rye/soybeans; T3: triticale/corn, grain sorghum/soybeans, triticale/ soybeans; T4: crambe/grain sorghum, canola/corn, safflower/soybeans; T5: lupine/corn + congo grass, beans/corn, buckwheat/black oats/congo grass. The experiment was arranged in a randomized block design, with four replications and 300-m2 plots. The data were subjected to analysis of variance, and means were compared by the Tukey’s test at 5% significance. The highest grain yield was obtained when soybeans were sown after white oats harvesting. Plant dry matter increased in the system with lupine/corn + congo grass, beans/corn, buckwheat/white oats/soybeans. However, none of the systems had an effect on soil chemical properties during the three crop years. O sistema de produção agropecuário mais comum na região noroeste do Paraná em solos originários do Arenito Caiuá é a pecuária bovina extensiva. Porém, esta realidade está mudando com o crescente cultivo de grãos, principalmente da cultura da soja. Componentes de produção da soja, matéria seca vegetal e atributos químicos do solo em sistemas de produção de soja foram avaliados em ARGISSOLO VERMELHO Distrófico arênico originado do Arenito Caiuá no Noroeste do Paraná. O experimento foi conduzido em Umuarama-PR, em sistema plantio direto durante três anos. Os tratamentos (T1: braquiária/soja, braquiária/soja, braquiária/soja; T2: aveia preta + centeio/soja, aveia preta + nabo/sorgo granífero, aveia preta + centeio/soja; T3: triticale/milho, sorgo granífero/soja, triticale/soja; T4: crambe/sorgo granífero, canola/milho, cártamo/soja; T5: tremoço/milho + braquiária, feijão/milho, trigo mourisco/aveia preta/soja) foram instalados em delineamento experimental de blocos ao acaso com quatro repetições, com 300 m2 por parcela. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey a 5% de significância. A soja tem maior produtividade de grãos após a cultura da aveia branca. O sistema de produção com tremoço/milho+braquiária, feijão/milho, trigo mourisco/aveia branca/soja, aumenta o aporte de matéria seca vegetal. Os atributos químicos do solo não são alterados pelos sistemas de produção avaliados, após três anos de cultivo.

An experiment was conducted at the Agronomic Institute of Parana – IAPAR, at the Experimental Station of the municipality of Santa Tereza do Oeste – PR, in Hapludox of clayey soil. Studies with the use of plants cover crops with vigorous root system in different systems of soil management systems are needed, in order to have a diversity of species capable of producing different amounts of crop residues which by decomposing, can alter the physical attributes and consequently, the productivity of the successor culture. The objective of this study was to evaluate the effect of crambe crop and plant cover crops in succession on the physical characteristics of a Haplortox under no-tillage system. The experimental area has been cultivated under no-tillage system for 18 years. The experimental area consisted of 15 plots, each plot with 20x25 m. In 12 plots, plant cover crops were planted, six species of summer and six of winter and the last three consisted of plots with no-tillage system with gypsum application, no-tillage system with scarification and traditional no-tillage (control) in a completely randomized design. The physical attributes of this soil were soil density (DS), total porosity (PT), microporosity (Micro), macroporosity (Macro) and saturated hydraulic conductivity (Ksat) of the soil in the periods of 2014 (initial characterization of the soil) and 2015 (after crambe culture). The microporosity (0.0-0.1 m layer) and Ksat (all soil layers) presented significant differences between treatments in the period of 2015. Microporosity was lower in the pigeon pea coverage (PP) (36.08%), while the largest occurred in the coverage of crambe C5 (45.38%). The Ksat was higher in the dwarf pigeon pea (DPP) (298.20 mm h-1) and sunn hemp (SH) (163.39 mm h-1) coverage in the 0.0-0.1 m layer. The highest Ksat was observed for crambe C9 (96.81 mm h-1), C8 (74.13 mm h-1), velvet bean (70.95 mm h-1) and C5 (53.94 mm h-1) respectively, in the soil layer of 0.1-0.2 m. Key words: Soil management, soil structure, residues.

O delineamento estatístico foi o inteiramente casualizado, disposto em esquema fatorial 5 x 7, com 3 repetições, onde o primeiro fator corresponde aos tratamentos: Testemunha; Bandejas rígidas de poliestireno revestidas com filme poliolefínico de 0,015mm (PD955); Bandejas rígidas de polietileno tereftalato (PET); Bandejas de poliestireno recobertas com filme de cloreto de polivinila (PVC) de 0,014mm; e Imersão em quitosana a 0,5%. O segundo fator foi o tempo de armazenamento, 0 (inicial); 4; 8; 12; 16; 20 e 24 dias, a 5 ºC (94 %UR). Cada parcela foi composta por 8 frutos, sendo que os tratados com quitosana foram contidos em bandejas rígidas de poliestireno, sem filme. Os resultados obtidos permitiram concluir que a proteção com filmes plásticos reduziu significativamente a perda de massa por lichias mantidas sob refrigeração, com redução na intensidade do escurecimento dos frutos. O tratamento com quitosana a 0,5%, em ácido tartárico a 10%, pH 0,8, mostrou-se efetivo na manutenção da coloração vermelha e na prevenção ao escurecimento, conservando a aparência dos frutos. The objective of the study was to evaluate the effectiveness of a modified atmosphere, by the use of plastic covers packaging and chitosan coverage in lychee postharvest storage. The experimental design was completely randomized in a factorial 5 x 7, with 3 replications, where the first factor corresponds to the treatments: control; rigid polystyrene trays (22.4cm x 14.8cm) coated with a 0.015mm (PD955) polyolefin film (PF); 500ml transparent rigid polyethylene terephthalate (PET) trays with lid; polystyrene trays covered with 0.014mm polyvinyl chloride (PVC) film; and immersion in 0.5% chitosan. The second factor was the storage time, 0 (initial), 4, 8, 12, 16, 20 and 24 days at 5 ° C, 94% RH. Each plot consisted of eight fruits, and those treated with chitosan were placed in rigid polystyrene trays without film. The results showed that the modified atmosphere reduced significantly the mass loss of fruits stored under refrigeration, especially with PVC film. Chitosan 0.5% proved to be more effective in maintaining the red color and preventing browning, keeping the fruits more attractive.

In this context, the objective of this work was to evaluate the growth, dry matter production, nutrient content and nutrients accumulation in sugarcane plants grown in nutritious solution, submitted to macronutrients omission, and to describe the visual symptoms of such omission. The experiment was carried out at the School of Agrarian and Veterinarian Sciences - Jaboticabal Campus, São Paulo, Brazil, with seven treatments (complete and with the omission of N, P, K, Ca, Mg and S), arranged in a completely randomized design, with three replications. Eleven weeks after the transplant to the nutrient solutions, the tiller number the fully developed leaves number, the height, the tillers diameter, the plant dry matter and the shoot and root macronutrient content of sugarcane were evaluated. N and P were the nutrients that limited the growth of sugarcane plants the most, with reductions of 91 and 57 %, respectively. However, regarding the root growth, the omission of N and Ca resulted in the greatest limitations, reducing the root growth in 83 and 48%, respectively.

Tecnologias que possam controlar o escurecimento do pericarpo são valiosas, e é o foco principal da pesquisa na área de pós-colheita. O objetivo deste trabalho foi avaliar a vida útil de lichias 'Bengal', armazenadas a 20 ºC e 82 %UR após o tratamento hidrotérmico e/ou imersão em solução de HCl. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 4 x 7, com 3 repetições, onde o primeiro fator correspondeu aos tratamentos: testemunha; imersão em HCl a 1%, por 6 minutos; tratamento hidrotérmico, com imersão em água a 52 ºC por 1 minuto, seguido de resfriamento em água a 10 ºC, por 6 minutos; e tratamento hidrotérmico, seguido de resfriamento em HCl a 1%, a 10 ºC, por 6 minutos. O segundo fator foram os períodos de armazenamento: 0; 1; 2; 3;6; 9 e 12 dias. A combinação entre tratamento hidrotérmico (52 ºC por 1 minuto) e resfriamento em HCl a 1% permite conservar a coloração das lichias 'Bengal' por até dois dias. Mesmo assim há escurecimento em 25% da superfície. One of the biggest problems in postharvest litchi pericarp browning is, the color red becomes totally dark in 48 hours at 25 º C. Technologies that can control the browning of the pericarp are valuable, and is the main focus of research in post-harvest. The aim of this study was to evaluate the shelf life of lychee 'Bengal', stored at 20 ° C and 82% RH after the hydrothermal treatment and/or immersion in HCl solution. The experimental design was completely randomized in a 4 x 7, with three replications, where the first factor was the treatment: control, immersion in HCl 1%, for 6 minutes; hydrothermal treatment, soaking in water at 52 ° C for 1 minutes, followed by immersion in water at 10 º C for 6 minutes, and hydrothermal treatment and subsequent cooling in 1% HCl, 10 ° C for 6 minutes. The second factor was the storage periods: 0, 1, 2, 3, 6, 9 and 12 days.

Mangas da cultivar Tommy Atkins produzidas em Livramento de Nossa Senhora, Bahia, foram analisadas com o objetivo de verificar a influência da aplicação pré-colheita de cloreto de cálcio na vida útil pós-colheita e em relação ao distúrbio fisiológico. As pulverizações de CaC1(2) foram realizadas em três épocas: 35; 65 e 95 dias após o florescimento. Os tratamentos foram concentrações de cloreto de cálcio: 0,0%; 2,0%; 3,5%; 5,0% e 6,5%. Frutos foram colhidos, transportados para o Laboratório de Biotecnologia da UESB, armazenados em câmara fria a 10ºC e 90% UR e avaliados por período de 35 dias. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 5 x 6 (concentração x tempo de armazenamento), com 3 repetições e 2 frutos por parcela. Os parâmetros analisados foram: perda de massa, firmeza, acidez titulável, pH, sólidos solúveis, relação sólidos solúveis/acidez, incidência e severidade de colapso interno. Durante o período de armazenamento, observou-se que, a partir do 28º dia de armazenamento, a perda de massa dos frutos foi menor em doses maiores de cloreto de cálcio. A firmeza e o teor de sólidos solúveis foram influenciados em maiores concentrações de CaC1(2), enquanto as demais características não foram influenciadas significativamente. A incidência e a severidade do colapso interno dos frutos não foram afetadas com uso de cloreto de cálcio. Verificou-se que a aplicação pré-colheita de cloreto de cálcio, em doses maiores (> 3,5%), aumenta a vida útil pós-colheita da manga, contudo não reduz a incidência do colapso interno. The fruits produced in Livramento de Nossa Senhora, Bahia, had been analyzed with the objective to verify the influence of spraying application of calcium chloride in pre-harvest period on shelf life of 'Tommy Atkins' mangoes. The sprayings of CaC1(2) were made three times: 35, 65 and 95 days after mango flowering. The used treatments were composed of the following concentrations of calcium chloride: 0.0%; 2.0%; 3.5%; 5.0% and 6.5%. The fruits were harvested, transported to the Laboratory of Biotechnology of Bahia Southwest State University, stored at 10ºC and 90% RH and evaluated during 35 days. The statistical design was an entirely randomized, using a factorial scheme 5 x 6, with 3 repetitions and 2 fruits/plot. The analyzed parameters were: loss of mass, firmness, titratable acidity, pH, soluble solids, soluble solids and titratable acidity ratio, incidence and severity of internal breakdown. During the period of fruit storage it was observed that in relation to the loss of mass, the fruits presented inferior loss when higher concentration of calcium chloride were used, from the 28th day of storage. For soluble solids and firmness they were also influenced in higher concentrations. For the other characteristics no differences were observed among them. No effects were verified in incidence and severity of internal breakdown in mangoes. From the results it can be concluded that the application of high concentrations of calcium chloride (>3,5%) in mango tree in pre-harvest period, increase shelf-life after 28 days of fruit storage, however it does not reduce the incidence of internal breakdown.

O objetivo deste trabalho foi determinar os efeitos do 1-MCP na qualidade de goiabas 'Paluma' minimamente processadas, armazenadas a 3ºC. O delineamento estatístico utilizado foi o inteiramente casualizado, em esquema fatorial 3 x 5, com 3 repetições, em que o primeiro fator correspondeu aos tratamentos: testemunha, aplicação de 1.000nL.L-1 de 1-MCP sobre o fruto intacto, antes do corte, e aplicação de 1.000nL.L-1 de 1-MCP no produto processado. O segundo fator foi o tempo de armazenamento (0; 3; 6; 9 e 12 dias) a 3ºC. Cada parcela foi composta por 10 metades. O 1-metilciclopropeno (1-MCP) não afetou a qualidade de goiabas 'Paluma' minimamente processadas e armazenadas a 3ºC, durante 12 dias, na concentração e no período de exposição estudados. The objective of this work was to determine the effects of 1-MCP in the quality of guava 'Paluma' minimally processed, stored at 3ºC. The experiment was carried out in a completely randomly design, in a 3 x 5 factorial scheme, with 3 replicates, in which the first factor corresponded to the treatments: witness, application of 1000nL.L-1 of 1-MCP on the intact fruit, before cutting and application of 1000nL.L-1 of 1-MCP in the processed product. The second factor was the period of storage (0, 3, 6, 9 and 12 days) at 3ºC. The experimental units were built up with 10 halves of fruits. The 1-MCP did not affect the quality of 'Paluma' guava minimally processed and stored at 3ºC during 12 days, in the studied concentration and period of exposition.

Palmer tratadas com 1-metilciclopropeno (1-MCP) mantidas sob armazenamento refrigerado e sob armazenamento refrigerado associado à exposição à temperatura ambiente por quatro dias. O delineamento experimental foi inteiramente casualizado, em fatorial 3 x 6, sendo 3 níveis do fator dose de 1-MCP (0 -testemunha, 100 nL.L-1 e 150 nL.L-1) e 6 níveis do fator tempo de armazenamento (0; 7; 14; 21; 28 e 35 dias de armazenamento refrigerado, no experimento 1, e 0; 7 + 4; 14 + 4; 21 + 4; 28 + 4 e 35 dias de armazenamento refrigerado + 4 dias sob condição ambiente, no experimento 2), com 3 repetições. Cada parcela experimental foi composta por 2 frutos. O uso de 1-MCP em mangas 'Palmer' mantidas sob refrigeração reduz as perdas de massa e ácido ascórbico, retardando, mas não impedindo o amadurecimento. O tratamento com 150 nL.L-1 não é mais eficiente que o com 100 nL.L-1, pelas características químicas analisadas. As mangas 'Palmer' expostas à condição ambiente por quatro dias apresentam expressivo murchamento e perda de qualidade, com base nas análises de sólidos solúveis, açúcares solúveis e acidez titulável. The objective of this work was to verify the behavior of mangoes cv. Palmer treated with 1-methylcyclopropene (1-MCP) stored under refrigeration and under refrigeration associate in exposure for four days at room temperature. The experiment was carried out in a completely randomly design, 3 x 6 factorial, with 3 levels of the factor concentration of 1-methylcyclopropene (0 nL.L-1- witness, 100 nL.L-1 and 150 nL.L-1) and 6 levels of the factor period of storage (0, 7, 14, 21, 28 and 35 days of cool storage, on the set up 1, and 0, 7 + 4, 14 + 4, 21 + 4, 28 + 4 and 35 days of cool storage + 4 days of room storage, on the set up 2), with 3 replicates. The experimental units were built up with 2 fruits. The use of 1-methylcyclopropene on the fruit kept under refrigeration reduces the weight and ascorbic acid losses, delaying but not avoiding the ripening. The treatment with 150 nL.L-1 is not more efficient than that with 100 nL.L-1, in accord to the analysed chemical characteristics. The increased weight loss of fruits stored under environmental conditions promoted expressive shriveling and loss of quality, on the basis of analyses of soluble solids, soluble sugars and titratable acidity.

Porém somente após sua introdução na Flórida passou a ser mais conhecido e procurado, principalmente pelos latino-americanos. Para diversas fruteiras, a distinção entre variedades pode ser realizada com base em características dos frutos, permitindo a diferenciação dessas plantas. Diante disso, realizou-se o presente trabalho, verificando a possibilidade da distinção de plantas de mamey pertencentes à coleção do Banco Ativo de Germoplama, da FCAV, Câmpus de Jaboticabal-SP, através de características físicas e químicas dos frutos. Foram avaliadas: massa (g), comprimento (cm), diâmetro (cm), rendimento de polpa (%), acidez titulável (AT), sólidos solúveis (SS), ácido ascórbico (AA), pH e relação sólidos solúveis/acidez titulável de frutos de treze plantas de mamey. Com base nos resultados obtidos, pode-se concluir que existem diferenças significativas para todas as variáveis avaliadas entre as diferentes plantas de mamey, possibilitando a seleção de matrizes promissoras, para implantação de pomares comerciais. The mamey sapota (Pouteria sapota) is original from Mexico and Central America, but it is quite common in Cuba, North of South America and the West Indies. However, only after its introduction in Florida, mamey has become well-known and sought especially by Latin Americans. The distinction among varieties can be done based on fruit characteristics, what permits the differentiation of these plants. In this context, the present research was accomplished, verifying the possibility to distinguish plants from mamey sapota belonging to the collection of the Active Germoplasm Bank, in the FCAV, Campus of Jaboticabal, São Paulo State, Brazil, by physical and chemical characteristics of the fruits. It was evaluated: weight, length, width, pulp percentage, soluble solid (SS), titratable acidity (TEA), ascorbic acid (AA), pH and SS/TEA ratio for thirteen plants of mamey sapota. There was a statistical difference between all the mamey sapota plants studied, making possible the selection of promising plants for the implantation of commercial orchards, and distinguishing the plants whose fruits present desirable characteristics for industrial use.

As mangas foram tratadas com 1-MCP nas concentrações de 0, 100 e 150nL.L-1, durante 12 horas à 22ºC. em seguida, foram armazenadas em câmara fria a 10 ± 1ºC e 80 a 90% de UR, por um período de 35 dias. A cada 7 dias foram retirados 6 frutos de cada tratamento para as seguintes avaliações: firmeza, pectina total, percentagem de solubilização de pectinas, atividade da pectinametilesterase, poligalacturonase e â-D-galactosidase. O tratamento com 1-MCP, associado à refrigeração mostrou ser eficiente em prolongar a vida útil dos frutos. Os frutos tratados com 150nL.L-1 apresentaram menor percentagem de solubilização de pectina e mais firmes no final do armazenamento, quando comparados aos outros tratamentos. Após 35 dias de armazenamento refrigerado, todos os frutos estavam aptos para o consumo, indicando que outros estudos deverão ser realizados aumentando o tempo de armazenamento. The objective of this work was to evaluate the effect of the 1-MCP in the firmness of mangos ´Palmer' stored under refrigeration. The mangos were treated with 1-MCP in concentrations of 0, 100 and 150nL.L-1, during 12 hours at the 22ºC.

O objetivo deste trabalho foi verificar a possibilidade de produção de goiaba de boa qualidade comercial, em diferentes épocas do ano, de acordo com podas realizadas em setembro e dezembro de 2003, março e junho de 2004. Utilizaram-se goiabeiras, cultivar Pedro Sato, com os ramos podados a 30 cm da base, sem desfolhamento, com quatro anos de idade, em delineamento de blocos ao acaso. Avaliaram-se: número de frutos produzidos, produção por planta, firmeza, sólidos solúveis (SS), acidez titulável (AT), relação SS/AT, pH e açúcares solúveis totais. Observou-se que as épocas de poda afetaram de maneira expressiva as características avaliadas. A produção de frutos por planta variou de 269,8 a 500,8 e foi inversamente proporcional ao peso dos frutos (186,9 a 205,5 g). A produção foi entre 55,5 e 93,6 kg por planta. O período de poda também influenciou as características físico-químicas dos frutos, mas não afetou a firmeza. É possível a produção de frutos de boa qualidade ao longo de nove meses do ano, com o manejo das podas. The objective of this work was to verify the possibility of fruit production at different periods, according to the pruning time (September and December 2003 and March and June 2004). The experimental design was a randomized blocks with guava plants of cultivar Pedro Sato per repetition, with four-years old, no defoliation, and branches prunned with 30 cm length. Evaluations consisted of: number of fruits per plant, plant yield, firmness, soluble solids (SS), titratable acidity (AT), SS/AT ratio, pH and total soluble sugars. It was observed that the pruning periods affected these characteristics. The fruit number per plant varied from 269.8 to 500.8. Fruit weight (186.9 to 205.5 g) was inversely proportional to the yield per plant. The total yield weight of fruits varied from 55.5 to 93.6 kg per plant. The pruning period also influenced significantly physio-chemical characteristics of the fruits, but not the fruit firmness. It is possible to produce high quality guava fruits during nine months of the year by prunning plants in the periods above mentioned.

Os produtos hortícolas apresentam vida útil pós-colheita limitada, devido às reações bioquímicas de natureza catabólica, que aumentam com a senescência, causando a morte dos tecidos. Avaliou-se o uso de películas de fécula de mandioca e PVC na manutenção da qualidade pós-colheita de pimentões (Capsicum annuum L.) armazenados em condições ambiente. Pimentões cv. Ikeda foram submetidos a 4 tratamentos: PVC, biofilmes nas concentrações de 3,5%, 4% e 4,5% de fécula de mandioca. Como testemunha foram utilizados frutos sem recobrimento de filme. As análises químicas foram realizadas a cada 2 dias, durante 8 dias de armazenamento, sendo avaliados a perda de massa, firmeza, acidez titulável (AT), pH, sólidos solúveis (SS), pectina total e pectina solúvel, coloração da casca e clorofila. O delineamento experimental foi inteiramente casualizado, em esquema fatorial com 25 tratamentos, 3 repetições e 2 frutos por parcela. Em todos os tratamentos, a firmeza e o pH diminuíram, enquanto a AT e os SS aumentaram no final do período de armazenamento em condições ambiente. Os tratamentos utilizados não ocasionaram alterações significativas no teor de pectina total durante o período de armazenamento, entretanto, menor teor de pectina solúvel foi observado nos frutos envoltos em PVC. Os frutos recobertos com biofilmes a 4 e 4,5% de fécula de mandioca apresentaram descamação da película a partir do sexto dia de armazenamento. A aplicação de PVC foi efetiva na manutenção da qualidade de pimentões cv. Ikeda, armazenados em condições ambiente por 8 dias. Horticultural products present limited post-harvest life due to catabolic biochemical reactions, which increase with age. The use of cassava starch films and PVC on the maintenance of post-harvest quality of bell peppers cv. Ikeda stored at room temperature was evaluated. The bell peppers (Capsicum annuum L.) were submitted to 4 modified atmospheres: PVC, edible coatings at 3.5%, 4% e 4.5% of cassava starch. Fruits submitted to regular atmosphere were used as control. Mass loss, firmness, titratable acidity (TA), pH, soluble solids (SS), total pectin, soluble pectin, peel color and content chlorophyll were evaluated every 2 days, over 8 days storage period. The experimental design was completely randomized block in factorial scheme with 25 treatments. Fruit firmness and pH decreased while TA and SS increased, at the final of storage period at room temperature, in spite of modified atmosphere. The treatments did not promote significant changes in the total pectin content during the storage period, although lower soluble pectin content was observed in the fruits covered with PVC. The edible coatings containing at 4 and 4.5% of cassava starch scaled from 6th day of storage. PVC covering was effective in the maintenance of quality of bell peppers cv. Ikeda, stored for 8 days under room temperature.
