The district wise monthly rainfall data for various districts of Eastern Uttar Pradesh recorded during the years 1981 to 2016. The rainfall seasons were computed year wise for various districts of Eastern U.P. Average area, production & productivity of the crops in the El Nino years were worked out and comparison with overall average normal value. was worked out during the period considered for present study from 1981 to 2016, 10 moderate and strong and two weak El Nino events out of 36 years. The average rainfall for the El Nino years was calculated and compared with the normal rainfall for the years 1981 to 2016 during the four different seasons.
