Abstract
Under the present investigation the span of 34 years data have been used to find out the effect of individual and joint effects. Four weather parameters (Maximum Temperature, Wind Speed, Rainfall and Bright Sun Shine) taken only according to their importance. The work has been carried out for rice crop in Ayodhya District of Eastern Uttar Pradesh. The correlation and multiple regression tech has been used to find out the effect of individual and joint effect. The maximum R2 60.7% showing in Maximum Temperature, followed by Rainfall with 56.2% R2, Wind Speed with 53% R2 and Bright Sun Shine with 52.7% R2. Similarly the joint effect of two weather parameters maximum R2 in Maximum Temperature and Wind Speed that is 64.8%, followed by Maximum Temperature & Rainfall and Rainfall & Bright Sun Shine with the R2 value 64.7% and 63.9% respectively. The minimum effect in joint combined variables showing in Wind Speed & Bright Sun Shine with 53.2% R2. This stage wise classified weeks and the effect of weather variables on yield has not been taken under the investigation earlier. This work will help for the scientists for future research on district wise data.
