Abstract:
The experiment entitled “Effect of integrated nutrient management on the performance of barley (Hordeum vulgare L.)” was carried out in Randomized Block Design (RBD) with four replications at Agronomy Research Farm, Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) during Rabi season 2016-17 with the objective of 1) Effect of combined use of organic manures and inorganic fertilizers on growth, yield attributes and yields of barley 2) Effect of various treatments on the nutrients uptake and quality of barley 3) Economics of various treatment combination. The experiment containing six treatments viz. 100% R.D.F (60 kg N + 30 kg P₂O₅ ha^-1), 75% R.D.F + 25% N through FYM, 50% R.D.F + 50% N through FYM, 75% R.D.F + 25% N through Vermicompost, 50% R.D.F + 50% N through Vermicompost, 50% N through FYM and 50% N through Vermicompost on silt loam soils having low organic carbon (3.8 g kg^-1), nitrogen (145.9 kg ha^-1), medium phosphorus (16.60 kg ha^-1) and potassium (250.20 kg ha^-1). All the growth and yield parameters increased significantly with75% R.D.F + 25% N through Vermicompost. The growth characters like plant height, dry matter accumulation, number of shoots, leaf area index were significantly higher under 75% R.D.F + 25% N through Vermicompost as compared to other nutrient combinations. The yield components like spike length (cm), number of grains spike^-1, spike weight (g), grain yield (kg ha^-1) and straw yield (kg ha^-1) were significantly higher under 75% R.D.F + 25% N through Vermicompost. Harvest index and 1000-grain weight (g) were not influenced significantly due to different nutrient combinations The nitrogen and protein content in grain were obtained higher with 75% R.D.F + 25% N through Vermicompost which was significantly higher than rest of treatments. The maximum net return (Rs.29020.00 ha^-1) and B-C ratio (1.30) were obtained at 100% R.D.F. Thus, it can be concluded that a dose of 75% R.D.F + 25% N through Vermicompost may be most suitable nutrient combination for achieving higher yield and economics of barley.
