A field experiment was conducted to investigate the effect of drip irrigation, spacing and nitrogen fertigation on yield of chilli (Capsicum annuum L.). The results revealed that drip irrigation enhanced the fruit yield, net income and minimized the time, weeds and diseases of the crop. Closer spacing at 30 cm produced higher yield (58.77%) and net income as compared to 45 cm spacing. Fertigation resulted in maximum yield (10.20 kg/m2), minimal disease and saved water and total irrigation time as compared to top dressing. The drip irrigation had significantly increased yield (10.50 kg/m2) and net income (60.30%) as compared to flood irrigation.
