Ajeet Kumar, AK Singh, Amit Kumar, RK Aryan and Kali Deen
The average rainfall for the El Nino years (strong and moderate El Nino) calculated and compared with the normal rainfall for the years 1981 to 2016 during the four different seasons and also computed for the seasons in different districts. Present study data revealed that the average rainfall during the S-W monsoon season during the El Nino years was less than the normal rainfall in all the district of Eastern UP. The average annual rainfall or S-W monsoon season rainfall were less than normal rainfall during the years with El Nino. Production and productivity of Chickpea crop were decline during El-Nino years as compared to normal. Maximum decline in production of Chickpea (33.1%) was recorded in Bahraich district, Maximum production of Rice crops were decline during (9.7%) in Varanasi district, Maximum decline in production of wheat (4.5%) was recorded in Bahraich district and Maximum departure in production of maize (23.3%) in Mirzapur. Agricultural production and productivity of the region during the El Nino years, As the S-W monsoon rainfall and annual rainfall are likely to less than normal in the region Duhan at al. (2017).. Short duration crops and varieties as main crops/intercropping system can be adopted in the region. Productivity of rabi crops can be improved by judicious use of fertilizers and adoption of insect pest & diseases control during the early stages of its growth. Plantation crops like fruit and timber plants are likely to yield decline due to decrease of pre- monsoon rainfall and therefore moisture conservation practices need to be adopted
