The Climatic Variability during Kharif Season in Prayagraj and Varansi District for Last One Decade. International Journal of Environment and Climate Change. 2023 Aug; 13(8): 1440-14462581-8627https://imsear.searo.who.int/handle/123456789/229175The present study attempts to know the trend of selected weather parameters and to analyse the impact of weather parameters on Yield of rice in Prayagraj and Varanasi district. The secondary data of weather parameters for the study was obtained from Sam Higginbottom University of Agriculture, Technology and Sciences (SHUATS).The weather data of Varanasi were obtained from Banaras Hindu University (BHU), Varanasi for the period from 2008 to 2018. The parameters consider viz., maximum temperature, minimum temperature, sun shine hour, rainfall and rice yield for the study. The variability terms (SD and CV) were computed over seasonal and annual periods for Maximum and Minimum Temperature, Rainfall of Prayagraj and Varanasi districts during 2008 to 2018.The long term trend in maximum, minimum temperature and rainfall, solar radiation has been calculated on monthly, seasonal and annual for Prayagraj and Varanasi. Trend was studied in 10 years period seasonal trend was observed for five seasons i.e. summer (March to May), south west monsoon (June to September), post monsoon (October and November), winter (December to February) and Kharif (June to november.) by using liner trend analysis. The linear trend value. The trend analysis revealed that the maximum temperature and minimum temperature showed a positive trend at Prayagraj whereas and rainfall and solar radiation showed a negative trend and the trend over a period during study period 2008-2018.Trend of one decades (2008-2018) was showed a decrease in Maximum Temperature, Minimum Temperature and Rainfall at Varanasi .The yield of Rice in Varanasi was positively correlated with rainfall; however negatively and significantly correlated with maximum temperature and minimum temperature and bright sun shine.Weather parameterstrendvariabilityMaximumminimum temperaturerainfallJournal ArticleIndiaDepartment of Environmental Science and Natural Resource Management, College of Forestry, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj 211007, IndiaDepartment of Environmental Science and Natural Resource Management, College of Forestry, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj 211007, IndiaDepartment of Environmental Science and Natural Resource Management, College of Forestry, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj 211007, India
