Resumo
The crop-livestock integration in no-tillage system (CLI-NTS) have emerged as a proposal of
conservationist production that promote improvements in soil attributes and, consequently, an
increase in crop productivity. Thus, the objective of this study was to evaluate the contribution
of between grasses and legumes in the pasture phase on the chemical and biochemical attributes
in CLI-NTS at the Mato Grosso and the performance of the soybean crop in succession. The
soybean crop was sown in the summer with harvest in February, with subsequent insertion of
the treatments with two grasses gramíneas (Urochloa ruziziensis e U. brizantha cv. BRS
Paiaguás) Cultivated single or intercropped with cowpea beans (Vigna unguiculata) cv. BRS
Tumucumaque and with pigeon peas (Cajanus cajan) cv. BRS Mandarim. With the use of
legumes, there was an increase in the total N stocks in the pasture stage, also observed for the
carbon and nitrogen of the microbial biomass and β-glucosidase demonstrating that the pasture
phase consortia decrease the stress conditions that the biomass undergoes. These results
culminated in the higher productivity of soybean in the treatments with consortium between
grasses and legumes, mainly with the use of cowpea beans, in pasture phase in CLI-NTS
promotes improvements in soil attributes and increases soybean accumulated productivity after
two years of system deployment.
