| This work aimed to evaluate the performance of six genotypes of sunflower under two spatial distributions between plant rows, and verify the cause effect relation between growth features. The experiment was carried at experimental area of Federal Technological University of Paraná (Campus Dois Vizinhos), evaluating six sunflower cultivars and two spatial distributions (40 and 80 cm between rows), remaining the total plant population similar, 55.000 plants by hectare. It was performed a path analysis, identifying the features that have most influence on sunflower grain yield and one hundred grain weight, also multiple regression analysis was used to estimate the equation for grain yield and one hundred grain weight. It was verified that sunflower genotypes... |

| The aim of this work was to evaluate the effect of nitrogen fertilization and aerial part cuts on yield components, grain yield and quality of the grains for dual-purpose wheat cultivars. The experiment was carried out between May and November 2007 and the experimental design was randomized complete blocks with three replications. The main causes of variation were dual-purpose wheat cultivars (BRS Figueira, BRS Umbu, BRS Guatambu and BRS Tarumã), nitrogen doses (0, 45, 90, 135 and 180 kg ha-1) and cut systems. Each plot was subdivided by cut management (without cut, one cut and two cuts). Spike mass, number of spikelets per spike, number of grains per spikelet, grain yield and hectoliter weight were evaluated. Nitrogen fertilization did not affect the... |
