One of the potential advantages of drip irrigation is allowing the use of fertilizer and poison with irrigation water. In this study, the effect of fertilizers on clogging dripper and drip irrigation system performance has been investigated. This study in a randomized block design framework was done that its factors were three treatment of fertilizer (ammonium phosphate) includes treatment F0 (control), and two F1 and F2 treatments with concentrations of 0.05 g/l and 0.08 g/l, respectively, and three dropper treatment (the in line long path and two outline long path). Dropper with codes A, B and C were named. In order to investigating dropper clogging, reduce discharge rate, efficiency of uniform distribution, Kristiansen uniformity coefficient and coefficient of discharge variation was calculated. The results were shown increasing concentration of irrigation fertilizer caused increasing dropper clogging and have a significant effect on discharge variation.
