摘要

A field experiment on integrated management of green manure (GM) and straw incorporation with inorganic fertilizers in rice-wheat cropping system was conducted. The apparent nitrogen recovery by rice was lower than that of wheat in the first year but reverse trend was observed in second years. The relative apparent nutrient recovery of N, P and K by rice and wheat in the both years was in the order: GM > GGSI > no GM or GGSI. In the second year, average apparent nitrogen recovery by rice in chemical fertilizer treated plot was 24.8%, which increased to 26.4 and 34.1% with the incorporation of straw of summer green gram and green manuring, respectively.
