Influence of Biofertilizers and Nitrogen on the Growth and Yield of Barley (Hordeum vulgare L.)

Abstract

The field experiment entitled “Influence of Biofertilizers and Nitrogen on the Growth and Yield of Barley (Hordeum vulgare L.)" 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 study included biofertilizers and three levels of Nitrogen (60, 80 and 100 kg/ha) and 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), EC (0.56 dS/m), 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 + Azospirillum and N 100 kg/ha produces higher plant height (95.10 cm), maximum number of tillers/running row meter (72.00) and higher dry weight (25.53g), maximum number of effective tillers/m2 (201.33), maximum number of grains/spike (51.20), higher grain yield (4.34 t/ha), straw yield (5.34 t/ha).
