Abstract
A field experiment was conducted at Acharya Narendra Deva University of Agriculture & Technology (ANDUAT), Ayodhya, U.P., duringthe 2024 kharif season on a silty loam soil toinvestigate the effect of inorganic fertilizer in combination with organic sources viz., vermicompost, poultry manure, FYM and biofertilizer such as Azolla on the yield attributes and yield of rice. RiceâSarjoo 52â showed significantly higher values of yield attributes (panicles m-2, panicle length, effective tillers per m², and test weight) under 50% RDN combined with FYM 5 t ha-¹, vermicompost 2.5 t ha-¹, poultry manure 1 t ha-¹, and Azolla 0.5 t ha¹. Maximum grain yield (5.79 t ha-1) and straw yield (7.47 t ha-1) were with 50% RDN combined with FYM 5 t ha-¹, vermicompost (2.5 t ha-¹), poultry manure (1 t ha-¹), and Azolla (0.5 t ha-¹). Integrated nutrient approach ensures a constant nitrogen supply during critical growth phases, enhancing nutrient uptake, promoting effective translocation of assimilates to the grains, and enhancing soil fertility as well as the plant growth. The results will highlight the benefits of integrated nitrogen management over the use of inorganic fertilizers alone in enhancing rice productivity
