The present study is based on the secondary sources of information on temperature, rainfall and Productivity of two major cereals (Rice and Wheat) in Azamgarh district of Eastern Uttar Pradesh. A total of 20 years data (2000-2020) on yield of crops, annual total rainfall, annual mean Maximum temperature and annual mean minimum temperature is analysed. The suitability analysis of crops shows that all the two cereals found to be suitable for cultivation in temperature range of Azamgarh district, whereas irrigation is required in addition to recorded rainfall in case of rice and wheat. The analysis of correlation coefficient shows that maize yield and minimum temperature have strong positive correlation (0.7755). At individual climatic factors level, yield of maize and wheat were significantly related with annual mean minimum temperature. The yield of these crops can be increased by crop management mainly by altering the planting time, varieties and irrigation practices.
