Impact of integrated nutrient management on growth parameters of Indian mustard (Brassica juncea L.) in the Prayagraj region

Abstract

The impact of integrated nutrient management on the growth and yield of Indian mustard (Brassica juncea L.) in the Prayagraj region was investigated through a field experiment, variety RH 725 at the Agriculture College Research Farm, Prof. Rajendra Singh (Rajju Bhaiya) University, Prayagraj (U.P.), during rabi season, 2024-25. The experimental field's soil had a sandy loam texture, an alkaline pH of 8.25, a low organic carbon content of 0.42%, and abundant amounts of nitrogen (181.60 kg/ha), phosphorus (16.50 kg/ha), potassium (230.47 kg/ha), and sulphur (7.38 kg/ha). Ten treatments using various nutrition management techniques include (T1) Control, (T2) 100% RDF, (T3) 75% RDF + FYM @ 5.0 t ha-1, (T4) 75% RDF+ vermicompost @ 1.5t ha-1, (T5) 75%RDF+ humic acid @ 5.0 kg ha-1, (T6) 75% RDF+ poultry manure @ 1.5t ha-1, (T7) 50% RDF + FYM @ 10.0 t ha-1, (T8) 50% RDF+ vermicompost @ 3.0 t ha-1, (T9) 50% RDF + humic acid @ 10. kg ha-1, (T10) 50% RDF + Poultry manure 3 t ha-1. were examined using three replications and a randomised block design. According to the experimental findings, the maximal growth parameters (plant height, dry matter accumulation and branches plant-1), yield attributes (siliqua length and siliqua plant-1), were recorded with application of 75%RDF+ humic acid @ 5.0 kg ha-1 higher than the rest of the treatments. Integrated nutrient management improves the soil health and sustains the productivity of Indian mustard.
