Role of Weather Parameters on Forecasting of Rice Crop in Eastern Uttar Pradesh, India | Chapter 10 | Current Research Progress in Agricultural Sciences Vol. 5

Rice is the major crop of Uttar Pradesh, which covers about 36.5 per cent area of the total gross-cropped area in Uttar Pradesh. Weather is one of the most important factors influencing crop growth. The effect of weather parameters at different stages of the growth of crops may help in understanding their response in terms of final yield and also provide a forecast of crop yields in advance before the harvest. The present study mainly deals with the effect of weather variables. The study was made for rice crops in the district of Faizabad, Uttar Pradesh, India in 2015. Weekly weather data on the weather variables of the Faizabad district of Uttar Pradesh during the different growth phases of rice crops have been obtained from the Department of Agro Meteorology, N.D. University of Agriculture & Technology, Kumarganj, Faizabad (U.P.), India. The data on three weather variables viz. rainfall, wind velocity and sunshine hours have been used in the study. The present study is formulated to determine the individual and joint effects of weather variables on rice yield. The prediction models have been also developed for rice crops through individual and joint weather variables. On the basis of R², it was found that individually sun shine (hr) is more important at 67.57% followed by wind velocity and rainfall at 48.63% and 46.74%, respectively. The joint effect of weather variables also plays an important role in the case of rice crops. According to R², the most important combination is rainfall & wind velocity with 82% followed by rainfall & sunshine hr and wind velocity & sun shine hr at 63% and 53.8, respectively. As far as is concerned with the individual effect of weather variables, it has been found that all the weather variables have made a significant impact on rice yield.
