Abstract:
A field experiment was conducted during Rabi 2020 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U. P). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36%), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The treatments which are T₁: control, T₂: Azotobacter + 100 kg/ha N, T₃: Azotobacter + 120 kg/ha N, T₄: Azotobacter + 140 kg/ha N, T₅: Azospirillum + 100 kg/ha N, T₆: Azospirillum + 120 kg/ha N, T₇: Azospirillum + 140 kg/ha N, T₈: Azotobacter + Azospirillum + 100 kg/ha N, T₉: Azotobacter + Azospirillum + 120 kg/ha N, T₁₀: Azotobacter + Azospirillum + 140 kg/ha N used. The experiment was laid out in Randomized Block Design with ten treatments each replicated trice. The results showed that application of Azotobacter + Azospirillum + 140 kg/ha N was recorded significantly higher plant height (86.07 cm), number of tillers/plant (6.34), dry weight (19.58 g/plant), number of effective tillers/m² (296.16), length of the spike (11.25 cm), test weight (46.93 g), number of grains/spike (58.11), grain yield (5.63 t/ha) and straw yield (13.20 t/ha), whereas harvest index (33.1%) was recorded maximum with Azotobacter + 120 kg/ha N.
