Soybean after the consortium corn with tropical forages in the savannah / Soja após consórcio de milho com forrageiras tropicais no cerrado

ABSTRACT

The biggest limitation to sustainable tillage in the Savannah region is the low biomass accumulation during autumn up to spring, due to low water availability and high temperatures characterizing these regions as having a warm and dry winter. The consortium of grains crops with tropical forages mainly of the genus Panicum and Urochloa is an alternative, to this situation. This study aimed to evaluate the effect of the straw production of Panicum and Urochloa after consortium with corn in the crop-livestock integration system on the soybean crop irrigated in succession. The experiment was conducted at the Farm for Teaching, Research and Extension, Faculty of Engineering - UNESP, Ilha Solteira in an Oxisol in Savannah conditions, being in no-tillage for 8 years (previous corn crop). The experimental design was a randomized block with four replications and four treatments Panicum maximum cv. Tanzania sown during the nitrogen fertilization (CTD) of the corn; Panicum maximum cv. Mombasa sown during the nitrogen fertilization (CMD) of the corn; Urochloa brizantha cv. Xaraés sown during the occasion of nitrogen fertilization (CBD) of the corn; Urochloa ruziziensis cv. Comum sown during the nitrogen fertilization (CRD) of the corn. After harvesting the corn and forages cuts, soybean was planted with seeds inoculated with Bradyrhizobium japonicum (Turfy with 600,000 viable cells/seed),
