Influence of Biofertilizers and Zinc on Growth and Yield of Barley

Abstract

The field experiment entitled “Influence of Biofertilizers and Zinc on Growth and Yield of Barley" was conducted during Rabi season, 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 a control. The experiment was layout in Randomized Block Design (RBD) with 10 treatments and replicated thrice. The soil in the experimental area was sandy loam with pH (8.0), Organic Carbon (0.62%), Available N (225 kg/ha), Available P (38.2 kg/ha) and Available K (240.7 kg/ha). Application of Azotobacter + PSB and Zn 30 kg/ha recorded growth parameters and yield attributes like, highest plant height (107.63 cm), maximum number of tillers/running row meter (66.32), higher Plant dry weight (22.31 g), maximum number of effective tillers/m2 (278.85), maximum number of grains/spike (52.27), higher grain yield (4.29 t/ha) and straw yield (6.72 t/ha).
