Abstract

A two-year experiment was conducted on sandy clay loam soil of Indo-Gangetic plain to investigate the effect of summer green manuring and nitrogen management on unpuddled transplanted hybrid rice (Oryza sativa L.) during its log phase of growth. The experiment was laid out in split plot design with four green manuring treatment in main plot viz. fallow, water hyacinth, Sesbania aculeata, sudan grass and three treatments in sub plot viz. 60 % RDN, 80 % RDN, and 100 % RDN with three replications. The results reported that the higher growth parameters viz. plant height, number of tillers/m2, dry matter accumulation, and number of leaves were recorded under Sesbania aculeata as compared to sudan grass and fallow, however, it was statistically at par with water hyacinth during both the years of experimentation. Among nitrogen management treatments, 100% RDN recorded higher growth parameters which was followed by 80% RDN during both the years. These results also imply that use of chemical fe

Conclusion

The results of two years of field study indicated that Sesbania aculeata incorporated at 45 DAS in soil recorded significantly higher growth attributes viz. plant height, number of tillers/m2, number of leaves/running meter, dry matter accumulation/hill, dry matter of leaves/hill, and dry matter of shoot/hill as compared to other green manuring treatments. Among all nitrogen management treatments, 100 % RDN (50 % nitrogen through FYM and 50 % nitrogen through inorganic) recorded significantly higher growth attributes as compared to other nitrogen management during both the years. The results clearly indicated the need of integrated use of green manuring in addition to chemical fertilizers to meet the nutrient need for optimum growth of rice.
