Abstract

This study was carried out to determine the effects of fertigation on clogging of emitters and DRIP IRRIGATION systems performances. The experiment was done in the water scinces Engineering lab, university of shahid chamran, ahvaz, from 2010 to 2011. In the experiment, three different emitters (on-line and 2 type in-line) and three different fertilizer (urea 46%N) Treatments (no-fertilizer, concentration 0.05 gr/l and 0.08 gr/l) are used. In control treatment f0, showed emitters A, B and C respectively %17.9, %19.9 and %11.38 discharge rate decrease. In treatment f1, showed emitters A, B and C respectively %22.8, %26.48 and %17.14 discharge rate decrease. In treatment f2, showed emitters A, B and C respectively %25.25, %33.67 and %19.16 discharge rate decrease. The results showed that the increasing of fertigation concentration, results in increasing clooging emitters. Clooging emitters decrease emission uniformity (Eu), Christiansen, s uniformity coefficient (Uc) and increasing of emitter discharge variations coefficient. Emitters that have the lowest flow rates had the lowest performance. These changes were different for all three type of emitters. The results showed thowed that emitters with code B were most sensitive to fertigation. Overally, sensitiveness to fertigatiuon were decreasing for emitters B, A and C respectively. Increase in concentration of irrigation fertilizer has a strong effect on the discharge of emitters and coefficient of discharge.
