Description A field experiment was carried out during Rabi season 2015-16 at Indira Gandhi Krishi Vishwavidyalaya, Raipur to validate the results of crop-weather relationship of different wheat varieties grown under different sowing environments.
In 50% flowering stage maximum temperature and rainfall was significantly correlated with grain yield and milking stage was observed significant correlation with maximum temperature. At CRI stage and tillering stage, relationship found non significant positive correlation with maximum temperature, minimum temperature, rainfall and sunshine while during tillering stage non significant negative correlation with minimum temperature. Has been found in non significant correlation with maximum temperature, minimum temperature, rainfall and sunshine, ear emergence and physiological maturity stage. In dough stage we found non significant positive correlation with rainfall and sunshine while maximum and minimum temperature are found to have non significant negative correlation with wheat yield.
In multiple linear regression maximum temperature have significantly to has been found influenced the grain yield of Kanchan variety of wheat during all stages except the Maximum temperature at maturity. The maximum temperature of Kanchan variety (based on probability values associated with t statistics) during 50% flowering stage and it was followed by milk stage. The highest positive significant effect of rainfall was observed during 50% flowering. Rainfall at crucial phases of CRI, tillering, emergence, 50% flowering, milking and dough stages is helping to meet the crop water requirement which includes maintaining soil moisture status and evapo-transpirational losses.
50 % flowering and milking stages were found significant for predicting yield in wheat. Rainfall and maximum temperature for different decades of 50 % flowering and milking stages are found predictors for the final yield. A multiple linear equation has been determined for wheat yield prediction in the Raipur condition.
