4. Forage mass and stocking rate of elephant grass pastures managed under agroecological and conventional systems
The objective was to evaluate elephant grass (Pennisetum purpureum Schum.) pastures, under the agroecological and conventional systems, as forage mass and stocking rate. In the agroecological system, the elephant grass was established in rows spaced by 3.0 m from each other. During the cool season ryegrass (Lolium multiflorum Lam.) was established between th

8. Effect of green manure species and their sowing dates on common bean crop.
Nitrogen is the most required nutrient by common bean (Phaseolus vulgaris L.). Although common bean can obtain this nutrient from atmosphere by the biological nitrogen fixation (BNF) process, the fixed amounts are not enough to supply all plant necessities. Under agroecological production systems, part of the required N could be supplied by green manures as
