The objective of this paper was to evaluate the influence of shading during the period of floral buds development on the growth and maturation of coffee fruits, production and grain size of Coffea arabica L. The experiment was carried out in Londrina, PR, Brazil. Plots of adult coffee plants were shaded monthly in April, May, June, July and August of 2004 using shading screens with 50% of porosity. The coverings were removed simultaneously at the beginning of October of the same year. The interception of 50% of incident radiation over the coffee canopy in different periods of floral buds development did not alter fruit growth and development. Fruit maturation was anticipated due to high temperatures and water deficit, however without significant differences on maturation periods among treatments. Grain yield and size were not affected by shading in the different periods. [ABSTRACT FROM AUTHOR]

Os sistemas integrados de produção agropecuários (SIPA), tem como finalidade a diversificação, rotação, consorciação e/ou sucessão de atividades agrícolas, possibilitando que cada atividade contribua positivamente e beneficie a atividade em sucessão ou simultânea. O objetivo deste trabalho foi avaliar a produtividade do milho submetido a níveis de adubação nitrogenada em sucessão ao consórcio formado por ervilhaca, aveia-preta e azevém e à resposta a inclusão da ervilhaca na cultura do milho, assim como o efeito do pastejo em um sistema de integração lavoura pecuária. O trabalho foi desenvolvido na Universidade Tecnológica Federal do Paraná (UTFPR), onde na parcela principal foram alocadas a combinação de espécies forrageiras: aveia + azevém e aveia + azevém + ervilhaca. Utilizou-se como adubação de base 32 kg ha-1 de N, 80 kg ha-1 de P2O5 e 60 kg ha-1 de K2O. Nas subparcelas as cinco doses de nitrogênio, na forma de ureia, aplicado em cobertura no milho (0, 75, 150, 225 e 300 kg ha-1) nas áreas com pastejo, e (0, 150 kg ha1 nas subparcelas sem pastejo.Avaliou-se a produção de silagem (kg ha-1 de MS),rendimento de grãos de milho (kg ha-1), população de plantas (plantas ha-1) e os componentes de rendimento, fileiras por espiga, grãos por fileira, grãos por espiga, massa de mil grãos (g), nitrogênio absorvido (kg ha-1) e no tecido (g kg-1)de plantas de milho.Nos componentes rendimento de grãos de milho e produção de silagem foram superiores nas áreas com cultivo de ervilhaca e apresentou uma resposta até a dose 250 kg ha-1 de N, enquanto que nas áreas sem ervilhaca no cultivo anterior, a resposta foi linear até a dose máxima utilizada. A utilização da ervilhaca consorciada com aveia e azevém em áreas é uma alternativa para diminuir o uso da adubação nitrogenada na cultura de milho cultivada em sucessão no sistema de integração lavoura pecuária, tanto para produção de silagem quanto para produção de grãos, além de propiciar um aumento nos teores de nitrogênio no tecido de plantas de milho. The integrated agricultural production systems (SIPA) has the purpose of diversification, rotation, intercropping and / or succession of agricultural activities, allowing each activity to contribute positively and benefit the activity in succession or a simultaneous one. The objective of this paper was to evaluate the productivity of corn submitted to nitrogen fertilization levels in succession to the consortium of vetch, oat and ryegrass and addressing the inclusion of vetch in maize, as well as the effect of grazing on a livestock farming integration system. The study was conducted at the Federal Technological University of Paraná (UTFPR), where in the main plot were allocated the combination of forage species: oat + ryegrass and oats + ryegrass + vetch. A base fertilizer of 32 kg ha-1 N, 80 kg ha-1 P2O5 and 60 kg ha-1 K2O was used. In the subplots, five levels of nitrogen, in the form of urea, were applied to cover the corn (0, 75, 150, 225 and 300 kg ha-1) in areas with grazing, and (0, 150 kg ha1) in subplots ungrazed . We evaluated the production of silage (kg ha-1 DM) yield of corn grain (kg ha-1), plant population (plants ha-1) and yield components, rows per ear, kernels per row, grains per ear, thousand grain weight (g) absorbed nitrogen (kg ha-1) and tissue (g kg-1) of corn plants. In the components, yield of corn grain and silage production were higher in areas with vetch cultivation and responded until the dose of 250 kg ha-1 N, while in areas without vetch in the previous crop, the response was linear up to the maximum dose used. The use of vetch intercropped with oats and ryegrass in areas is an alternative way to reduce the use of nitrogen fertilizer in corn grown in succession in livestock farming integration system, both for silage and for grain production, as well as providing an increase in nitrogen concentration in the tissue of maize plants.
