All rights reserved.A field experiment was conducted during the winter (rabi) seasons of 2017–18 and 2018–19 Udaipur, Rajasthan, to study the nutrient status of plant and soil as influenced under integrated nutrient management in barley (Hordeum vulgare L.). The experiment was laid out in randomized block design (factorial), comprising combinations of 6 fertility levels and 4 liquid bio-inoculants. The results indicated that, application of 125% recommended dose of fertilizers (RDF) in conjunction with 5 t farm yard manure (FYM)/ha had significant effect on yields (grain, straw and biological yield) which was at par with 100% RDF + 5 t FYM/ha. However, both these fertility levels significantly increased the grain weight/ear over application of 75% RDF + 5 t FYM/ha, 125% RDF, 100% RDF and 75% RDF during both years. Both 125% RDF + 5 t FYM/ha and 100% RDF + 5 t FYM/ha fetched net returns of ?66,492 and 64,933 with benefit: cost ratio 2.15 and 2.14, respectively. The barley crop under the influence of conjoint inoculation with liquid bio–fertilizers, consisting combination of Azotobacter + Azospirillum + phosphates solubilizer + plant growth-promoting rhizobacteria (PGPR) recorded significantly higher grain, straw and biological yields and was found at par with inoculation of Azotobacter + PSB inoculation, and both these treatments significantly influenced the grain, straw and biological yields. Inoculation of barley seed with liquid bio inoculant consisting combination of Azotobacter + Azospirillum + Phosphates solubilizer + PGPR recorded maximum net returns (67,906) and benefit: cost ratio 2.44 closely followed by seed inoculation with liquid bio inoculant Azotobacter + PSB with net returns of 65,006 and benefit: cost ratio of 2.31, registering significantly higher over inoculation with Azotobacter and PSB alone.
