In modern agricultural systems, chemical-based weed control is becoming difficult to ignore (usage of herbicides) in weed management because of its effectiveness to accomplish weed control and at the same time, increases yield largely. However, both economic and ecological attention the application of herbicide should be optimum. Keeping in view, the laboratory experiment was conducted and the performance of selected hydraulic energy nozzle through discharge rate,uniformity coefficient, the width of spray and angle of spray were measured and analyzed with a pressure range of 20 to 50 psi at an interval of 10 psi.Results of laboratory investigation show that the discharge rate, the width of spray, angle of spray and operating pressure viz., 0.98 lit/min, 32.5 cm, 63.5 deg and 40 psi of N1 (0.5 mm of orifice size) was found to be optimum for herbicide application in a cotton field.
