Abstract

The field experiment was carried out during the Kharif season of 2024-25 and 2025-26, at Student Instructional Farm, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya U.P. The experimental site is situated in the middle Gangetic plain’s agro-climatic zone, which is distinguished by rich soil and ideal weather conditions for transplanted rice. The field experiment was carried out using randomized block design with three replication and twelve treatments, consisting of Farmyard manure (FYM), Pressmud, Plant growth promoting rhizome, and Super absorbent polymer, are applied in field conditions in different treatment combinations. In this research work we observed the crop performance and its interaction with different treatment combinations under the field conditions. The result revealed that the maximum Plant height (cm), Number of tiller per m2 and Dry matter accumulation were improved by the incorporation of organic sources of amendments with the inorganic amendments and microbial population like soil microbial count bacteria (105CFU g-1), Actinomycetes (106CFU g-1) and fungi (104CFU g-1) was observed at harvest stage and showed significantly the highest in treatment combination having three organic sources which improve the soil fertility as well as crop productivity.
