Ravishankar, Devesh Pandey, AK Pali and AK Sahu
The present study was carried out to assess existing and alternative water supply and demand scenarios of the Nawagarh Distributary of Hasdeo Bango Irrigation Project, Chhattisgarh, India. The selected model uses the FAO (1992) Penman-Montieth method for calculating the reference crop evapotranspiration. These estimates are used in crop water requirements and irrigation scheduling calculations. In this study, assessing the supply and demand scenario for the summer rice and alternative rabi
crops (considering three most commonly grown crops is wheat, gram and sunflower). The seasonal applied canal water depth during the study period was about 112.52% (2012) and 138.25% (2013) more than the seasonal demands for the served area (SA). Therefore, more area can be brought under summer rice cultivation. The model estimated irrigation requirement for summer rice was in close agreement with the experimentally determined value of the region and thus, the selected model can be used as a tool for determining stagger irrigation requirement.
