Screening of timly sown wheat (Triticum aestivum L.) varieties in relation to climate change in central plain zone of Uttar Pradesh

Abstract

The field experiment was conducted during rabi season of 2017-18 at Student’s Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (UP) India to screen out timely sown varieties of wheat on the basis of their growth characters, yield attributes and yield under agroclimatic situation of Central Plain Zone of Uttar Pradesh. The treatments consisted ten wheat varieites viz. K307, K402, K607, K1006, HD-2733, DBW-17, HD2967, PBW-343, PBW-502 and PBW-550, laid out in Randomized Block Design replicated three times. The varieties were sown on 17th November 2017 and harvested of Physiological maturity ranged 130 days to 142 days after sowing. The inputs were given timely at recommended rates. The results exhibited that the performance of HD2967 and PBW-343 was found significantly superior over other varieties in terms of growth, yield attributes and yield. The variety HD-2967 recorded maximum grain yield (5590.0 kg ha-1), Harvest index (42.23%), net income (Rs. 80490ha-1) and B:C ratio (2.89) followed by PBW 343 recorded grain yield (5277.0 kg ha-1), harvest index (35.67%), net income (Rs. 65358-00 ha-1) and B: ratio (2.53) was recorded under PBW 502.
