Abstract:

Irrigation Scheduling is a prime requirement for optimizing the use of water resources in irrigated agriculture. The majority of irrigation projects in India perform at a low overall efficiency of 30% (Sarma and Rao, 1997), which provides an opportunity for meeting the increasing water demands by adopting efficient methods of water management. The National Commission on Integrated Water Resources Development (NCIWRD, 1999) has projected that India’s surface irrigation systems will work at only 40, 50 and 60% efficiency levels in 2010, 2025 and 2050, respectively. This demands for optimization of canal irrigation Scheduling. With this in view the present study has been carried out for kharif crop in the Right bank canal command area of Shahid Veer Narayan Singh Dam. In present study after analyzing water requirements during the entire growth period of Paddy crop (Main Kharif crop of the study area), data on seasonal water discharge, soil data, meteorological data have been collected and irrigation scheduling of Paddy crop was carried out through the application of CROPWAT 8.0 Software with the aim to maximize crop cultivation area and Optimum utilization of Water resources. The designed discharge capacity of water in the study area of Right bank canal at head is 6.65 cumecs and after analysis it was found that in practice 19.92 Mm3 of water is supplied in the study area. During the Kharif season, crop water requirement (CWR) scheme supply requires only 8.95 Mm3 after optimization through CROPWAT 8.0 software, which is only 44.92 % of actual supplied water. Therefore saving of 5.01 Mm3 of water is supplied as surplus quantity which can be saved by reducing the canal regulation days.
