Influência da palhada obtida através do consórcio de feijão Guandu e brachiaria para a produtividade da cultura da soja

Abstract

The crop-livestock integration is favorable for the productive system, so as to improve the parameters of water availability and nutrient cycling, in this work the Guandu bean was intercropped with Brachiaria Paiaguas, in different populations of pigeon peas per plot and the same population for brachiaria in all treatments. The objective of this work was to evaluate the productivity of the soybeans sown in a consortium of pigeon pea and brachiaria in different bean populations per linear meter, as well as to determine the nutrient stock provided by the consortium straw, the populations used were 0, 3 , 6, 9, 12 and 15 plants of pigeon pea per linear meter, 12 kg ha-1 (VC = 60%) were used. For the determination of dry matter a sample was collected in each plot of 2.25 square meters of the fresh matter and taken to greenhouse to obtain the respective dry matter, and to obtain the respective contents of each nutrient a bromotological analysis of a sub sample thereof. The soybean planting in succession of the brachiaria consortium with pigeon pea beans results in good soil cover, nutrient cycling, nitrogen fixation. Having as treatments they stood out with 15 and 12 pigeon bean plants per linear meter.
