摘要: A preliminary investigation was conducted in 1 m2 microplots using two stem nodulatedAeschynomene species,A. afraspera andA. nilotica, to evaluate their beneficial effects as green manure on the yield and nitrogen content of rice.A. nilotica yielded 7.5 9.2 kg m−2 fresh matter, (42.3 53.2 g N respectively) 7 weeks growth. Green manuring increased grain by more than 80% over control 45% rice fertilized with 10 N-urea m−2. The straw significantly higher treatments Aeschynomene other treatments.
