Emitter clogging is the common and serious problem associated with drip irrigation. An attempt was made to study drip emitter clogging with the objective of comparing relative emitter discharge, reduction of mean discharge, emission uniformity, and percentage of completely clogged emitters. Experiments were conducted at different concentration of clay viz. 5% and 10% and at different operating pressures viz. 0.6 kg/cm2, 0.8 kg/cm2 and 1 kg/cm2. mitter perfomances under different treatments were analysed. Emitter discharge variation with operating pressures for online and inline drip emitters were studied. Clogging was maximum in case of inline drip emitters at higher pressures and at lower pressures few online drip emitters were also clogged. At higher operating pressure, online drip emitters work satisfactorily without clogging. Similarly, mean discharge reduction of inline drip emitters were more at higher operating pressure and at lower pressures discharge of online drip emitters were less. Percentage of completely clogged inline drip emitters was 25%, whereas that of online drip emitters was 5 % only.
