Venturi injector is a commonly used device for fertilizer application through drip irrigation. The injection rate of venturi mainly depends upon the suction created due to difference between its upstream and downstream pressures. A commercially available was evaluated under range operating pressures from 1.0 2.0 kg.cm-2 using normal irrigation water solution. Maximum with 106.4 l.h-1 at pressure kg.cm-2. (105.8 l.h-1), when urea dissolved in ratio 0.25:1 (urea: water) 0.1 kg.cm-2, respectively. However, muriate potash (MOP) 1:1 (MOP: water), minimum 1.44
