Biomass production and macronutrients quantity of millet, jack bean, guandu single and in intercropping

The object of this work was to evaluate the biomass production and the macronutrients quantity of millet (Pennisetum typhoides (Burm.) Stapf), jack bean (Canavalia ensiformes (L.) DC.), guandu (Cajanus cajan, (L.) Millsp.) dwarf cultivar, and the millet with leguminous consortiums to straw production in no-tillage system. The experiment was carried in experimental area at Agriculture Department of the Federal University of Lavras (Lavras, Minas Gerais state, Brazil). The experimental design was randomized blocks, with five treatments and four replications. For biomass production, only the guandu presented smaller fresh and dry biomass yield than the other treatments. In general, the leguminous presented the greatest N and Ca quantities and millet the greatest quantities of S. Only jack bean presented minor P quantity. For K the greatest quantities were verified for single milett and its incropping with leguminous and jack bean in intercroppin with millet. The minor quantities of Mg were observed for guandu.
