COMPETIÇÃO DE CULTIVARES DE SOJA EM ÁREA DE REFORMA DE PASTAGEM, ANO AGRÍCOLA 2006/07

Abstract

The abundance of soybean cultivars in the market, due to the intense work of the plant breeders, offers to the producers wide diversification of options, fitting the once again researches the determination of those more recommended for each soil type and the local climatic conditions of an area. Thus, it was objectified to evaluate the agronomic performance of the soybean cultivars in the area of Colina-SP, in area of pasture reform, in the agricultural year 2006/07. The experimental design was the randomized block, with four replications. Each plot consisted by four row of 5 meters in length, considering as useful plot the two central row. The rows were spaced 0.5 m. The data were submitted to the variance analysis by the test F, being the averages compared by the test of Tukey at 5%. It was verified that cultivars them they behaved as precocious. With relationship to the productivity, she stood out the cultivar CD 201. The medium values of plant height and insert of the first pod, loyding, number of seeds, pods, branches and nodes for most of the you cultivars were appropriate as the demands for the succession pasture/soybean, demonstrating the potential of those cultivars, for grown in the area of Colina-SP.
