Substitution of nitrogen requirement of maize through leaf biomass of Leucaena leucocephala: agronomic and economic considerations

Substitution of nitrogen requirement of maize through leaf biomass of Leucaena leucocephala:... In a 3-year field study, the effects of substitution of nitrogen requirement of maize through Leucaena leaves were studied on runoff, soil loss, maize and wheat yield and economic returns. The treatments were (1) 80 kg N ha-;1 all through Leucaena leaves (80 L), (2) 40 kg N through Leucaena leaves + 40 kg N ha-;1 through fertilizer (40 L + 40 F), (3) 20 kg N through Leucaena leaves + 60 kg N ha-;1 through fertilizer (20 L + 60 F), (4) 80 kg N ha-;1 all through fertilizer (80 F), and (5) control (No fertilizer). Green Leucaena leaf biomass (containing 3.3% N on dry basis) was incorporated every year in 15 cm top soil two weeks before sowing of summer maize. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Agroforestry Systems Springer Journals

The treatments were (1) 80 kg N ha-;1 all through Leucaena leaves (80 L), (2) 40 kg N through Leucaena leaves + 40 kg N ha-;1 through fertilizer (40 L + 40 F), (3) 20 kg N through Leucaena leaves + 60 kg N ha-;1 through fertilizer (20 L + 60 F), (4) 80 kg N ha-;1 all through fertilizer (80 F), and (5) control (No fertilizer). Green Leucaena leaf biomass (containing 3.3% N on dry basis) was incorporated every year in 15 cm top soil two weeks before sowing of summer maize.
