Abstract

A field experiment was conducted at Regional Agricultural Research Station, Vijayapura, during the rabi season 2023-24, to study the response of wheat genotypes to different growing environments. The experiment was laid out in Randomized Complete Block Design (factorial concept) with three replications. There were twelve treatment combinations,which consist of four sowing windows viz., II fortnight of October, I fortnight of November, II fortnight of November and I fortnight of December and three genotypes viz., UAS 304, UAS 334 and UAS 375. Significantly higher grain yield(2534.72 kg ha-1) and straw yield (4915.12 kg ha-1) was recorded when wheat was sown during II fortnight of October, it wasfollowed by I fortnight of November sowing with grain yield of 2166.74 kg ha-1 and straw yield of 4244.29 kg ha-1. Similarly,significantly higher yield attributes viz., number of panicles, panicle weight and grain weight per metre row length and testweight were recorded under II fortnight of October sowing. Among the genotypes, UAS 334, recorded significantly highergrain yield of 2138.71 kg ha-1, which was on par with genotype UAS 375. Different combination of treatments hadsignificant influence on wheat yield. Sowing of genotype UAS 334 during II fortnight of October recorded significantlyhigher grain yield of 2684.95 kg ha-1, maximum gross returns (`117035 ha-1), net returns (`67933 ha-1) and B:C (2.38).
