Abstract
The present study aimed to determine the Sowing dates and varieties of wheat can affect yield, nutrient content in grain, straw and soil after crop harvest. A field experiment was conducted during Rabi season (2015-16) at Instructional Farm, Department of Agronomy, College of Agriculture JAU, Junagadh to evaluate the identification of the suitable date of sowing and variety of wheat (Triticum aestivum L.) for South Saurashtra, Gujarat under changing climatic conditions. The experiment consisted of 12 treatment combinations of four dates of sowing in main plots (05th November, 15th November, 25th November and 05th December) and three varieties in sub plots (GW 322, GW 366 and GW 173) was carried out in split-plot design with three replications. Significantly maximum grain yield, N, P and K in grain and straw was recorded with sowing on 15th November and with the sowing of GW 366. Higher available N, P2O5 and K2O in the soil after harvest was found on 05th December and GW 173.
