Abstract:
The field experiment was conducted during Rabi season of 2020 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P). The soil of the experiment plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.82%), available N (291.24 kg/ha), available P (32.85 kg/ha) and available K (264.78 kg/ha). The experiment was laid out in randomized block design with ten treatments and were replicated thrice. The treatments consisted of different biofertilizers combination (Azotobacter, Azospirillum and Azotobacter + Azospirillum) and three zinc levels (Zinc @ 25 kg/ha (Soil application), Zinc @ 0.5% (5 g/l) (Foliar application) at 25 and 50 DAS and Zinc @ 1% (10 g/l) (Foliar application) at 25 DAS) and one control plot, respectively. Results obtained that maximum plant height (102.43 cm), number of tillers (11.07/plant), dry weight (22.32 g/plant), crop growth rate (28.11 g/m²/day), relative growth rate (0.0164 g/g/day), grains (43.47/spike), spikes (402.00/m²), test weight (54.26 g), grain yield (5.93 t/ha), straw yield (9.37 t/ha) and harvest index (39.72%) were recorded with application of Azotobacter + Azospirillum + 0.5% Zn (Foliar) at 25 and 50 DAS.
