Abstract
The reported study was conducted to assess the impact of prolonged annual canal closure on wheat production. The duration of canal closure usually, notified 18 days under study areas was prolonged to 54 days during rabbi season. As a result, 43.7% of total wheat area could not get 1st irrigation in time. In addition, the variability, inadequacy and unreliability in water supply proved to be key obstacle in increasing wheat yield per hectare. Consequently, a decrease of 4600 tons of wheat yield was estimated tone on the tail reach areas of all distributaries/minors in Punjab. The farmers of study area have to bear a loss Rs.13.77 million in terms of local market rate and the nation has to manage US$ 1.025 million for importing wheat for this area. If similar situation had prevailed on all the tail reaches, then a national loss of Rs.2100 million would have occurred and an amount of US$ 172.80 million would be added in the debt of nation as a result of indigenous canal operational system.
