Effect of Integrated Nutrient Management (INM) on Growth and Yield of Mustard (Brassica juncea L.)

Abstract

The present study was conducted at Crop Research Centre (CRC), School of Agriculture, ITM University, Gwalior (MP) to investigate the effect of integrated nutrient management (INM) on growth, yield and quality of mustard (Brassica juncea L.). The experiment was laid out in the randomized block design with three replications and each replication was comprised of eleven treatment combinations comprising FYM (Farm Yard Manure) and Azotobacter with recommended dose of N, P, K and S (80: 60: 30: 30). These treatments were investigated for different morphophysiological, yield and quality attributes of miaze crop. Significant improvement in different morpho-physiological attributes viz., plant height, number of branches per plant and dry matter at 30, 60 and 90 days after sowing (DAS), was recorded with T5 treatment. The seed yield was recorded highest (11.33 q/ha) with T5 treatment (100% RDF + FYM @ 15 t/ha + Azotobacter @ 5kg/ha). Maximum harvest index (25.54 %) was also calculated highest for T5 treatment followed by T3 treatment (18.77%) (100% RDF + FYM @ 15 t/ha). Comparatively, the improvement in protein (34.67%) and oil content (39.30%) in mustard cake was maximum for T5 treatment to other treatments. The results of the study revealed that T5 treatment had the maximum significant effect on yield and quality of the mustard crop.
