Abstract:
An Experiment was conducted to check the effect of fertility levels and weed management practices on the Weed Dynamics, yield and Economics of Transplanted Rice (Oryza sativa L.) at Agricultural Research Station, Faculty of Agricultural Sciences, Institute of Agricultural Sciences, Siksha ‘O’ Anusandhan Deemed to be University, Binjhagiri, Chatabar, Khordha, Odisha during kharif, 2019. The experiment was conducted in a Factorial RBD design having twelve treatments each of three replications, which consisting of three levels of fertility (100% RDF, 75% RDF and 50% RDF) and four weed control methods (Almix @ 4g /ha, Bispyribac sodium @ 25 g/ha, Hand weeding at 20&40 DAT and weed check). Sahabhagi Dhan variety was used for the experiment. From this experiment, we found that the combination of 100% RDF with post emergence application of Bispyribac sodium @ 25 g/ha recorded highest plant growth attributes, yield attributes, grain yield (3.63 t/ha), straw yield (4.76 t/ha) and reducing the cost of cultivation and also recorded the maximum net return (Rs.31, 746/ha) and return per rupee investment (1.81).
