Abstract
The present investigation was carried out during Rabi season of 2022-23 at Students' Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur. The experiment was designed with two factors, viz. wheat varieties (DBW-187 and PBW-723) in the main plots and plant growth promoters (PGPs) viz., micronutrients (Zn, Fe, B, Cu) @ 0.5%, nitrobenzene @ 3 ml l-1, gibberellic acid @ 2 ml l-1, seaweed extract liquid @ 625 ml ha-1, seaweed extract solid @ 25 kg ha-1, UPL Macarena (Fermented extract nutrient 15%) @ 625 ml ha-1, Humesol (humic acid 18 %, fulvic acid 15 %) @ 1250 ml ha-1, and Amino Booster G (30 % amino acid solution) @ 5 ml l-1 were selected in sub-plots. These treatments were compared with a control treatment. The experiment was laid out in a Split Plot Design and replicated three times. The results revealed that significant variations were noticed in different treatments. The wheat variety DBW-187 exhibited superior growth and yield attributes, with a grain yield of 4601.8 kg ha-1, surpassing other variety. Among plant growth promoters the blend of micronutrients (Zn, Fe, B, Cu) @ 0.5% foliar spray at tillering stage resulted in the significant maximum plant height (86.55 cm), crop growth rate (0.243 g m-2 day-1), at 45 to 90 DAS, number of tillers (425.13 m-2) at maturity, grain yield (4572.17 kg ha-1) and straw yield (7072.20 kg ha-1). The gibberellic acid @ 2ml l-1 and seaweed extract liquid @ 625 ml ha-1 also showed significant results.
