Produtividade de soja com dupla finalidade e manejos de cultivo em Garanhuns-PE

Abstract

In Agreste Pernambucano, soybean production can bring great financial benefits for local producers and significant contribution to the dairy industry through his employment as an alternative source of protein for the flock, but the absence of technological equipment and technical incentive for its production is that this crop is not exploited. Aimed to study the recommendation of soy cultivation techniques for the Pernambuco Agreste. The experiment was conducted in field conditions during the growing season of 2013, the Federal Rural University of Pernambuco, Academic Unit of Garanhuns. The effect of the presence and absence of fitoestimulante was observed in different crop densities (12, 14, 18 and 22 plants per meter) is also carried cut at 45 days after emergence. Was installed in a randomized block design, split plot (4x2) schema. The density of 22 pl.m-1 promotes initial growth of plants. Density of 14 pl.m-1 estimulate ® increases the yield. Density of 22 pl.m-1 without estimulate® enhances biological productivity, the rate of crop growth and yield of straw. 12 pl.m-1 with estimulate® favors the harvest index. When done cutting, planting density of 22 pl.m-1 promotes germination speed index and the presence of estimulate ® increases the first count, biomass productivity at the time of harvest, final biomass and total biomass of soybean matched against the absence of stimulating® increases grain yield, harvest index and grain filling rate, this density. The densities of 14 and 18 pl.m-1 estimulate® reduces the mortality of plants. The use of estimulate® stimulates the growth of the crop and straw yield a density of 22 pl.m-1.
