Abstract

Several problems are associated with drip irrigation system. Clogging of emitters appears to be one of the aimed most annoying problems related to drip irrigation. This research aimed to study the effect of injector types, irrigation requirements and nitrogen treatments on drippers clogging. To attain this target, three types of fertilizer injectors were investigated: by-bass pressurized mixing tank (J1), venture (J2), and positive displacement pump (J3). Three irrigation treatments were used 50 (I1), 75 (I2), and 100 (I3) % of ETc, and three levels of N- fertilizer (NH4)2SO4 namely 60 (N1), 90 (N2), and 120 (N3) kg/fed. The emitter clogging percentage was measured for the drip irrigation system at the beginning and the end of garlic growing season 2006 / 2007. According to clogging percent, the used injectors were arranged in the ascending order: J3 > J2 > J1. Differences in clogging percent among the used injectors were significant at the 5% level. Emitter clogging increased with increasing nitrogen application, and decreasing the irrigation rate. The maximum and minimum values of clogging percent were (17.79, 22.8; 27.9) and (13.24, 15.81; 18.9) under the condition of   (J3, J2; J1), (I1 × N3) and (I3 × N1), respectively.
