Abstract
The experiment was conducted to study the performance of various seed hardening chemicals in late sown variety of wheat (Triticum aestivum L.) at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences (SHUATS), Prayagraj (U.P.) The experiment comprise of 13 treatment within 3 replication laid out in a randomized block design to evaluate the performance of various seed hardening chemicals viz. Distilled water, KNO3 at 1000mg per liter, PEG at 15% and GA3 at 450 mg/ liter. The highest straw yield (45.15t), grain yield (3.52t) and harvest index (7.27) was observed in the treatment PEG at 15%+Three Irrigations at crown root initiation, jointing and anthesis stage. The highest cost of cultivation (₹50894.00), gross return (₹59678.00), net return (₹36801.00) and B:C ratio (1.723) is also observed inT9, respectively.
