ABSTRACT
The study was carried out in one of the districts of Nangarhar province located in Eastern Afghanistan between latitude 34.25o N and longitude 70.50o E. Nangarhar has huge ground and surface water resources. There are 78 irrigation canals in the province having an overall length of 365 km. Behsud Canal is located in the Behsud district of Nangarhar province of Afghanistan. The results showed that the highest crop water requirements were found for the month of July in Behsud Canal. Similarly, water application efficiency ranged recorded from 34% to 65.2%. Average evapotranspiration was found to be 49% in the present canal. The irrigation water demand increased with the increased size of the agriculture field for the production of crops in the Behsud Canal of Nangarhar province.
