Abstract
The field experiment was conducted at the agronomy research farm of Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya, Uttar Pradesh to access the effect of optimization of nutrient management practices on yield and nutrient uptake of maize during kharif season of 2023 and 2024. The experiment was laid out in factorial randomized block design (FRBD) with 3 replications and consists three RDF Levels 50% RDF (NPK), 75% RDF (NPK) and 100% RDF (NPK)) and five Bio-agent enriched FYM and micronutrient (Zn @ 5 kg ha-1 + B @ 1kg ha-1, Enriched FYM @ 5 t ha-1, Enriched FYM @ 10 t ha-1, Zn @ 5 kg ha-1 + B @ 1kg ha-1 + Enriched FYM @ 5 t ha-1, Zn @ 5 kg ha-1+ B @ 1kg ha-1+ Enriched FYM @ 10 t ha-1). Results indicate that among the RDF levels crop fertilized with 100% RDF (NPK) recorded the maximum grain yield (44.07 q ha-1) and nutrient uptake by crop. Among the Bio-agent enriched FYM and micronutrient application of Zn @ 5 kg ha-1 + B @ 1kg ha-1 + Enriched FYM @ 10 t ha-1recorded significantly the highest grain yield (48.07 q ha-1) and nutrient uptake by crop during both the years.
