Abstract:

The water conservation is vital to maintain agricultural production in areas of small rainfall or jagged rain sharing. Under this situation, surface and Sub-surface drip irrigation   may play a momentous role in overcoming the paucity of water and economic production of vegetable crops, particularly in water shortage areas. Drip irrigation is the most efficient slow, even application of low-pressure water to soil and plants using plastic tubing placed near the plants' root zone. But Clogging is one of the most important problems encountered in this irrigation system which significantly reduce the efficiency of the system which consequently may encounter severe economical consequences in terms of the system operation, maintenance and the ultimate goal for sustainable crop production. The experiment was conducted at the Soil and Water Engineering Laboratory under the Faculty of Agricultural Engineering, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal during the period of 2015-16. The lateral contained 94 emitters of nominal discharge 4.0lph. However, the newly used emitters gave the average discharge of 4.18 lph at 1.05kg/cm2 pressure. The emitters were nonstop operated for 29 days and the reduction of discharges for clogging for each and every emitter was determined at 0, 8, 15 and 29 days interval. Chlorination was performed by injecting bleaching powder in a 300 ml of water for 30 minutes. After performing chlorination, the discharges were measured at 1, 3, 6 and 9 days interval to evaluate the performance of chlorination on clogging. The improvements of discharges of the emitters were found about 14 and 23% in 3 and 6 days respectively after chlorination. It was also found that there is no improvement of chlorination after 6 days.
