Abstract
A Field experiment was conducted during the Rabi season of 2023-24 at crop research center of ITM University Gwalior, (M.P.) India, to investigate the âEffect of integrated nutrient management practices on yield and economics of barley (Hordeum vulgare L.)â. The experiment followed a Randomized block design (RBD) with three replications. The experiment consisting of twelve treatments combinations viz., T1- Control, T2- 100% RDN, T3- 125% RDN, T4-100% RDN + Seaweed (foliar app.), T5-100% RDN + Seaweed (soil Treat.), T6-100 % RDN + Azotobacter + Azospirillum, T7-100 % RDN + seaweed (Soil treat.) + Seaweed (Foliar Appl.), T8-100 % RDN + PSB + PGPR, T9-75 % RDN + Azotobacter + seaweed (Foliar appl.), T10-75 % RDN + Azotobacter + seaweed (soil treat.), T11-75 % RDN + Azotobacter + PSB + seaweed (Foliar app), T12-50 % RDN + Azotobacter + PSB + Sea weed (Soil treat.) + Sea weed (Foliar app). The results revealed that the application of 100 % RDN with the seed treatment of Azotobacter and Azospirillum exhibited significantly higher spike length and grains/spike and yield of barleycrop, over rest of the treatments, except125% RDN (T3) and 100 % RDN + PSB + PGPR (T8). However, the application of 100 % RDN and seed treatment with Azotobacter and Azospirillum was recorded higher growth and yield of barley. Whereas the highest net returns (Rs. 58999.74) and benefit-cost ratio (1.48) was calculated with the treatment of T6 (100 % RDN + Azotobacter + Azospirillum).
