Effects of Different Nutrient Management Methods on Growth and Yield of Barley (Hordeum vulgare L.)

Abstract

A field experiment was conducted during the Rabi season of the year 2022-2023 at the KVK Farm, Mahendergarh of CCS Haryana Agricultural University, Hisar during Rabi season 2022-23 with the objective to study the effect of different nutrient management practices on growth and yield of barley. The experiment containing eleven treatments viz. Control, 100% RDF (60 kg N + 30 kg P2O5 + 15 kg K2O ha-1, 100% RDF) + Azotobactor + PSB, 50% RDF + Azotobactor + PSB, 50% RDF + 50% RDN through Vermicompost, 50% RDF + 50% RDN through Vermicompost+ Azotobactor + PSB, 75% RDF + Azotobactor + PSB, 75% RDF + 25% RDN through Vermicompost, 75% RDF + 25% RDN through Vermicompost + Azotobactor + PSB, 100% RDN through vermicompost and 100% RDN through vermicompost + Azotobactor + PSB. All the growth and yield parameters increased significantly with75% R.D.F + 25% N through Vermicompost. The growth characters like plant height (cm) and number of tillers/mrl were significantly higher under 75% R.D.F + 25% N through Vermicompost + Azotobactor + PSB as compared to other nutrient combinations. The yield components like spike length (cm), number of grains spike-1, grain yield (kg ha-1) and straw yield (kg ha-1) were significantly higher under 75% R.D.F + 25% N through Vermicompost+ Azotobactor + PSB. 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 + Azotobactor + PSB which was significantly higher than rest of treatments. Thus, it can be concluded that a dose of 75% R.D.F + 25% N through Vermicompost + Azotobactor + PSB may be most suitable nutrient combination for achieving higher growth and yield of barley.
