Growth Characteristics, Yield Components and Yield of Wheat (Triticum aestivum L.) as Affected by Integrated Nutrient Management on under Central Plain Zone of Uttar Pradesh

Abstract

Field experiments were carried out at Chandra Shekhar Azad University of Agriculture & Technology, Kanpur, to investigate the influence of integrated nutrient management on wheat growth metrics, yield components, and yield during the rabi seasons of 2021-22 and 2022-23.The trial included 11 treatment combinations in a randomised block design with three replications and each treatment combination likely involves different combinations of inorganic fertilizers, organic manure, and biofertilizers. Wheat variety HD-2967 was grown with the using prescribed agronomic practices. According to investigation results the maximum plant height at maturity is 99.85 cm and 102.79 cm, the maximum number of effective tillers is 101.45 cm and 104.83, and the maximum ear length is 11.29 cm and 11.76 cm are associated with the treatment T10 [100 % NPK + S40 + Zn5 + Fe10 + Azotobacter + PSB + 5 tonne FYM] during both years of experimentation. Similarly, among the yield components and productivity parameters maximum values with regard to the number of spikelet ear-1 (22.64 and 22.95), grain ear-1 (43.11 and 46.03), 1000 grain wt. (41.17 and 42.13 gm), grain yield (48.60 and 49.93 q ha-1) and straw yield (63.15 and 67.53 q ha-1) have been observed in the treatment T10 [100 % NPK + S40 + Zn5 + Fe10 + Azotobacter + PSB + 5 tonne FYM] during both the years of the experimentation. The objective of the study to understand how different combinations of inorganic fertilizers, organic manure, and biofertilizers affect the growth and productivity of wheat, specifically the HD-2967 variety, when grown using recommended agronomic practices.
