Abstract
A field experiment titled âEffect of Nitrogen levels and inoculation of Biofertilizers on growth and yield of Wheatââ was conducted during Rabi 2022-23 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The treatments consists of three different levels of Nitrogen-100%, 75% and 50% with combination of different levels of Azotobacter and Azospirillum. The experiment was laid out in Randomized Block Design with ten treatments which are replicated thrice.The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 6.9), low in organic carbon (0.112%), available N (278.93 kg/ ha), available P (10.8 kg/ha), and available K (206.4 kg/ha). The results obtained that combined application of Nitrogen 100% -150 kg/ha along with Azotobacter10g/kg and Azospirillum10g/kg seed (Treatment-3) significantly increased higher plant height (85.00 cm), number of tillers/hill (8.2), plant dry weight (21.00 g), number of effective tillers/hill (6.03), number of grains/spike (50.06), grain yield (4.96 t/ha) and straw yield (7.00 t/ha).
