Abstract

                                A pot experiment was conducted to study the influence of well decomposed organic manures, zine enriched (ZnE) organic manures, different levels of Zn on ADT-36 rice yield and organic carbon and available Zn content in post-harvest soils. Two types of soils were used for the pot experiment. The experiment was conducted adopting completely factorial randomised design. The results revealed that grain and straw yield of rice was associated with the application of ZnE organic manures I tha than the recommended level of organic manure @ 12.5 t ha-1. The enrichment of organic manures @ 1.25 mg Zn kg-1 increased the grain and straw yield to the tune of 26 per cent over on Zn application which showed the possibility of reducing fertilizer Zn rates. Among the ZnE organic manures, FYM+ GLM enriched with 1.25 mg Zn Kg increased grain yield markedly over organic manures @ 12.5 t.ha-1.
