Evaluation of the developed strategy at field level to enhance crop water productivity in Sirsa District

The study was carried out in Sirsa, the north western district of Haryana State. The soil texture in the belt along Ghaggar River varies from silt loam to silty clay loam. About 90% of the net area sown is irrigated against the State average of about 81% and national average of about 40%. Of the total net area irrigated in the district, about 80% receives supply from the canal irrigation system. The conclusion shows the probability of getting average annual rainfall (300- 350 mm) is at 50% chance. Probability (P) and Recurrence Interval (RI) of annual one-day maximum runoff series based on 15 years of data (N). The average relative water supply RWS (ratio of water supply and water demand over a period of time) was observed to be 0.72 in summer and 0.65 in winter at the head reach and 0.58 in summer and 0.50 in winter at the tail reach of watercourses. At present, wheat in the Rabi season and cotton or rice in the Kharif season are the main crops.The amount of inflow and outflows components and balancing of irrigation components based on the monthly deficiency and storage of water. The depth of water application to field is 0.1016 m., and tube well discharge is 135.46 m3/hr. There are a large numbers of tanks and ponds in the district which act as water conservation structures and ground water recharge structures in the district.
