Influence of Biofertilizer and Zinc on Yield and Economics of Barley (Hordeum vulgare L.)

The field experiment "Influence of Biofertilizer and Zinc on Yield and Economics of Barley" was carried out during the Rabi season of 2022 at Crop Research Farm in the Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh. The treatment consisted of Biofertilizers [Azotobacter, PSB and Azotobacter + PSB], Zn (20, 25 and 30 kg/ha) and control. The experiment was designed using Randomized Block Design (RBD) and reproduced three times. The soil in the experimental area was sandy loam with a pH of 8.0, 0.62% organic carbon, 225 kg/ha available nitrogen, 38.2 kg/ha available phosphorus, and 240.7 kg/ha available potassium. Azotobacter + PSB + Zn 30 kg/ha increases grain production (4.29 t/ha), straw yield (6.72 t/ha), gross return (108675 INR/ha), net return (78555 INR/ha) and B:C (2.61).
