Abstract
During the Rabi season of 2021-22, a field trial was carried out in micro plots within the 'pot culture house' at the Department of Soil Science & Agricultural Chemistry, Chandra Shekhar Azad University of Agriculture and Technology in Kanpur. The study involved nine treatment combinations arranged in a randomized block design with three replications, aiming to assess the impact of nitrogen (N), phosphorus (P), potassium (K), and Azotobacter on the wheat variety K-1317. Based on the findings obtained from the study, it can be deduced that concerning the growth parameters maximum plant height is 77.51 cm, maximum number of tillers plant-1 is 6.00 were associated with the treatment T6 [125 % RDF + Azotobacter]. Similarly, among the yield components and productivity parameters maximum values in relation to length of ear (12.75 cm), number of grain ear-1 (57.67), fresh weight plant-1 (156.24 g), dry weight plant-1 (25.25 g), grain yield (52.00 q ha-1), straw yield (65.80 q ha-1) and biological yield (101.96 q ha-1) were also found in the treatment T6 [125 % RDF + Azotobacter]. While the minimum value of growth, yield attributes and yield parameters were also found under the treatment T1 [Control].
