Abstract
Aims: This field experiment was conducted to find out the effect of integrated nitrogen management on growth and yield of kharif maize.
Study Design: In the experiment, five nitrogen management treatments were taken in Randomized Block Design (RBD).
Place and Duration of Study: This field experiment was conducted for consecutive two kharif seasons in 2022 and 2023 at Agronomy Farm of B. A. College of Agriculture, Anand Agricultural University, Anand.
Methodology: In the experiment, five nitrogen management treatments were taken in Randomised Block Design (RBD) viz T1:100% Recommended Dose of Nitrogen (RDN) through chemical fertilizer, T2:100% RDN through farm yard manure (FYM), T3:75% RDN through FYM + 25% through chemical fertilizer, T4:50% RDN through FYM + 50% through chemical fertilizer and T5:50% RDN through FYM + 25% through chemical fertilizer + Bio NPK consortium with four replications.
Results: The various nitrogen management treatments significantly affected growth plant height at 30, 60 DAS and at harvest, grain yield and straw yield. Application 100% RDN through inorganic fertilizer (T1) to recorded significantly higher grain yield and straw yield, it was remained statistically at par with T4 (50% RDN through FYM + 50% RDN through chemical fertilizer) and T5 (50% RDN through FYM + 25% RDN through chemical fertilizer + Bio NPK consortium) in both the years and in pooled analysis.
Conclusion: Application 100% RDN through inorganic fertilizer (T1) gave the highest plant height, grain yield and straw yield, closely followed by a 50% RDN from FYM + 50% from chemical fertilizer.
