1. Coberturas de solo e desempenho de híbridos de tomateiro na implantação do sistema de plantio direto / Soil cover and tomato hybrid performance for notillage system implementation
O objetivo do trabalho foi avaliar o efeito de diferentes coberturas de solo sobre o desempenho de quatro híbridos de tomateiro rasteiro (AP 529, AP 533, Katia e Sicílio) na implantação do sistema de plantio direto, bem como o efeito da cobertura na fertilidade do solo. As características agronômicas avaliadas foram produtividade, massa média, produç

2. Manejo da cultura da soja e plantas invasoras sob cobertura vegetal de aveia preta e consÃrcio de aveia preta, ervilhaca comum e nabo forrageiro
The adjustment of a cover crop to the agricultural system, with species whose chemical composition has substances able to control weeds, is a promising alternative to decrease herbicides application in agriculture. So, this trial aimed at analyzing the interference of black oats residues as well as black oat, common vetch and forage turnip consortium on weed

3. Uso de resíduos vegetais em solos ácidos sob sistema de plantio direto
The Brazilian soils are characterized by low natural fertility, where the main chemical limitations are high acidity and low basic exchangeable cation saturation that can affect the majority of cash crop productions. Liming is the principal practice to reduce soil acidity and to increase basic cations in these soils with high pH-dependent cation exchangeable

4. Microclimate and gerbera growth under different greenhouse covers. / Microclima e produção de gérbera em ambientes protegidos com diferentes tipos de cobertura.
The objective of this work was to evaluate the influence of white polyethylene as a greenhouse cover and its association with different shading screens (thermal screen and black screen) on the following environmental elements: incoming solar radiation (Qg), photosynthetically active radiation (PAR), temperature (T), relative humidity (RH) and evapotranspirat

5. Variabilidade interanual de campos atmosféricos totais e zonalmente assimétricos / Interannual variability of total and zonally asymmetric atmospheric fields
Interannual variability of total and zonally asymmetric atmospheric fields is studied through analyses of variances and Empirical Orthogonal Function (EOF) patterns as well as using correlation maps between principal component time series and filtered anomalous time series of some variables for DJF and JJA periods. The period of study spans from 1979 to 1995
