Effect of Seed Hardening and Irrigation on Growth and Yield of Wheat (Triticum aestivum L.)

The experiment was conducted at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences (SHUATS) Prayagraj (U.P.) located at 25˚ 24' 42" N latitude, 81˚ 50' 56" E longitude and at an altitude of 98 m above mean sea level during the rabi season 2019-2020 to evaluate the performance of various seed hardening chemicals viz. Distilled water, KNO₃ at 1000mg/l, PEG at 15% and GA₃ at 450 mg/lin late sown variety of wheat (Triticum aestivum L.).The plant height was highest in GA₃ at 450 mg/l + Three Irrigations at crown root initiation, jointing and anthesis (81.27 cm), the maximum dry weight was noted in PEG at 15%+Three Irrigations at crown root initiation, jointing and anthesis stage (24.00 g). The no. of total effective tillers/m² (402), straw yield (45.15t), grain yield (3.52t) and harvest index (5.82) was observed in the treatment PEG at 15%+Three Irrigations at crown root initiation, jointing and anthesis stage.
