TLDR
In this paper, green manuring in situ with sunnhemp (Crotalaria juncea) and dhaincha (Sesbania aculeata) significantly improved growth and yield of transplanted rice.Abstract:
Green manuring in situ with sunnhemp (Crotalaria juncea) and dhaincha (Sesbania aculeata) significantly improved growth and yield of transplanted rice. Giving the green manure crops 15 kg N/ha or 15 kg N and 30 kg P2O5/ha further increased yield. Interaction between green manuring and N fertilizer revealed that a considerable quantity of fertilizer N (45–60 kg N/ha) applied to rice could be replaced by incorporation of green manure crops to which a small amount of fertilizer had been applied. Residual fertility in terms of organic carbon and available N, P and K increased under green manuring, whereas N fertilizer made no impact on fertility build up. Grain yield of wheat and gram increased when grown after rice in plots which had grown green manure.read more

Nitrogen Dynamics And Management In Rice-Legume Cropping Systems
R. J. Buresh,S. K. De Datta +1 more
TL;DR: This chapter reviews nitrogen (N) dynamics in lowland rice fields with emphasis on how N dynamics are influenced by typical soil drying and wetting cycles, the influence of legumes on soil N transformations and N accretion in rice-based cropping systems, the N contribution of legumed to rice, and the integrated management of legume N and industrial fertilizer N for rice.

Efficient Management Of Leguminous Green Manures In Wetland Rice
TL;DR: In this paper, the agronomic advantages of applying green manures to wetland rice as a source of both nitrogen and organic matter are discussed. But the most studied benefit of leguminous green manure is its contribution to N nutrition of the rice crop.
