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