Title : Growth and yield performance of wheat (Triticum aestivum L.) varieties under different sowing times

Abstract :

The present investigation was carried out during the Rabi season of 2016-17 at the research farm of Wheat & Barley Section, Chaudhary Charan Singh Haryana Agricultural University, Hisar. The experiment was laid out in a split plot design with four sowing times (5th November, 15th November, 25th November, 5th December) in main plots and four wheat varieties (WH 1105, HD 2967, HD 3086, DBW 88) in subplots with three replications. A delay in sowing time from 5th November to 5th December significantly reduced the growth parameters in terms of plant height, dry matter accumulation and number of tillers. Among wheat varieties, the maximum number of tillers and dry matter accumulation were registered in HD 3086 whereas, the maximum plant height was in HD 2967. Sowing of wheat on 5th November resulted in significantly higher yield attributes viz. effective tillers, grains per earhead and 1000 grain weight resulting in 27.4 and 9.7 per cent higher grain yield and harvest index, respectively as compared to 5th December sowing. Among wheat varieties, the highest numbers of effective tillers and 1000 grain weight were recorded with HD 3086 whereas, the maximum number of grains per earhead was recorded in WH 1105. Maximum grain yield (5822 kg/ha) and biological yield (14023 kg/ha) were obtained from HD 3086.
