Abstract:

A field experiment was conducted during autumn season of 2016-17 and 2017-18 to study the effect of micro climatic regimes and nitrogen management on growth, yield attributes and yield of direct seeded rice. The experiment was laid out in factorial randomized block design with three replications. The treatment consisted of four micro climatic regimes i.e., M1, M2, M3, M4 and N management (N1: 100 % RDF of N as inorganic; N2: 75% N as inorganic + 0.5 t/ha vermicompost (V.C.); N3: 50 % N as inorganic + 1.0 t/ha V.C.; N4: 25% N as inorganic + 1.5 t/ha V.C.). The crop sown early on 1 April (M1) showed significantly superior in growth parameters than the crop sown late on 15 May (M4). Application of 50% N as inorganic along with vermicompost@ 1.0 t/ha resulted significantly highest yield attributes and grain as well as straw yield as compared to other nitrogen management practices.
