Biomass production of green manure cultivated in agroforestry systems

Abstract

The objective of this work was to evaluate the green and dry biomass production of aerial part of green manure grown in an  SAF of IFPE/Campus Barreiros. The green manures were planted in lines and between lines of perennial crops, in four quadrants: IPA 206 cowpea, jack bean, sorghum and bean guandu, at a spacing of 0.5 x 0.5 m, with three seeds per in a total population of 120,000 plants / ha. Four random samples were collected in each quadrant, and these were composed of three plants cut in full bloom at 10 cm from the soil. Sorghum and guandu bean showed better yields of dry shoot biomass of 31 t ha^-1 and 19 t ha^-1, respectively. The species selected have developed well in the region, however, the choice of a green manure species will depend on the specific objectives of each farmer, which also involves seed availability, crop rotation, species adaptation, among others.
