A field experiment was conducted on crop Residue and Nitrogen Management under Rice-Wheat cropping System to determine the influence of Nitrogen and rice straw management on growth, yield, and yield attributes of wheat crop at farmer’s field near VKSCOA, Dumraon, Buxar during the Kharif season of 2020-21 and 2021-22. The experiment was laid out in split plot Design with sixteen treatment Combinations and three replications in which there were four levels of rice straw management (S1-Straw Incorporated (SI), S2-Straw Incorporated + EM 1% Spray (SIE), S3- Straw Retention & Surface Mulching (SR), S4-Straw Retention & Surface Mulching + EM 1% Spray (SRE) and four levels of Nitrogen (N1-Control (No Nitrogen), N2-75% RD of N, N3- 100% RD of N, N4-125% RD of N). Among the rice straw management significantly highest plant height (97.4cm), no. of tillers (325 per m2),no. of grain per ear head (318) and wheat yield (38.75 q/ha) under Straw Retention & Mulching +EM 1% and under Nitrogen Management yield was significantly found higher (43.18) in 125% RD of N.
