Abstract: newline Drought is universally recognized as a water scarcity phenomenon. Proper assessment of newlinerainfall and vegetation is an essential requirement to reduce drought intensity. During the newlinecurrent study, 40-year monthly rainfall data were used for the calculation of meteorological newlinedrought frequency by using the Rainfall anomaly index (RAI) and standardized precipitation newlineindex (SPI), While Agricultural drought has been monitored by the MODIS NDVI newlineVegetation Condition Index (VCI) over Upper Gangetic Plains. Spatial and temporal newlinevariations in meteorological and vegetative droughts in the Upper Gangetic Plains have been newlineanalyzed and correlated for monsoon month. The results revealed that RAI and SPI showed newlinethe similar drought event from the study period while the VCI maps indicate that vegetation newlinegrowth is dependent on water supply through rainfall and irrigation. These indices have been newlinefurther compared with wet year (2013) and drought year (2015). Most of the eastern and newlinecentral areas of the study were dry. The study shows that a combination of different indices newlineshowed a good understanding of drought in order to define potential sites for reducing risk in newlinethe future. The present study was planned to determine the phenology and heat unit newlinerequirement of promising wheat varieties under different crop growing environment of newlinePrayagraj, India. Delay in sowing of wheat results into reduction in the grain yield as the newlinecrop exposes to high temperature at phenological stages. A field experiment on wheat newline(variety PBW-502) was conducted at the farm nursery, College of Forestry, SHUATS, newlinePrayagraj during rabi seasons of 2018-19 and 2019-20. The experiment was conducted in newlinefactorial randomized block design and replicated thrice with three dates of sowing and five newlineirrigation levels. The yield attributes (grain and biological yield) were significantly newlineinfluenced by sowing dates and irrigation levels. The significantly highest grain and newlinebiological yield were recorded in crop sown on 15th November as compare
