in this research, amount of evaporation and transpiration and water requirement of wheat plant for marvdasht town (representation station: zaraghan) during 17-years statistical duration from 1989-2005 and properties of plant and soil are calculated using cropwat software. at the first, trends of dry and wet periods for mentioned station were determined using long-term average of climatic data (...

Background: The increasing population and need for higher quantity of food grain production necessitates efficient use limited water in the country, as agriculture sector alone uses 78% resources India. During rabi season, mostly crops are grown with irrigation southern Odisha. There is no enough information on requirement maize, sorghum pearl millet region, which necessitated this study. Metho...

Abstract The study is conducted to examine the climate change impact on rice Crop Water Requirement (CWR) and Net Irrigation (NIR) using NASA Earth Exchange Global Daily Downscaled Projection (NEX-GDDP) coupled with CROPWAT 8.0 model. maximum temperature (Tmax), minimum (Tmin), rainfall projections for baseline (years 1981–2015) future 2030 2040) under Representative Concentration Pathway (RCP)...

By using the GIS technologies, we interpolate the site-based meteorological data into climatic surface data, which are the main input parameters for the CropWat model, used to estimate the reference evapotranspiration (ET0). And then by combining the ET0 with the information on share of cultivated land decoded from the Landsat TM/ETM digital imagines covering the entire case study area, the Hua...
