Effect of Sowing Dates and Varieties of Wheat Crop (Triticum aestivum L.) on Growth and Productivity under Changing Climate

The field experiment was conducted at Crop Research Station Masodha, Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhaya (U.P) during Rabi season November, 2017-April, 2018. In the environment, growth wheat greatly influenced by temperature changes associated with sowing dates. productivity is highly vulnerable to climate change. laid out in Split plot design (SPD) 3 replication and four different dates (05th November,25th 15th December, 05th January) a main against six varieties Wheat crop (HD-3086, HS-562, HI-1544, WR-544, MACS-6222 HD-2967) sub plot.. Growth parameters were higher early sown crops as compared late crops. Among HD-3086 on 25th November obtained highest parameter HD-2967, WR-544. yield potential or variety are outcomes genomic, environmental agronomic interactions. Due reduction tillering period increased risk hot weather grain filling, planting results linear yield. it may be concluded that optimum time compare wheat. most promising variety.
