Drip system of irrigation provides enhanced water use efficiency and water application efficiency up to 90% whereas it is about 70% for sprinklers and 45% for flood method of irrigation. In this method as water is supplied directly to crop root zone through drippers, water losses in distribution and conveyance are far lower than those under flood irrigation. A case study was conducted regarding performance evaluation of drip irrigation system used for growing brinjal in the village Shivpur, district Mungeli in Chhattisgarh. The study was conducted in 50 ha area of farmer’s field, irrigated with drip irrigation. The emitter discharge was found to be 0.85 lph. The number of emitters installed in brinjal field in 1 ha area was 90. In all 5 pumps were supplying water to different crops, out of which 4 were electric operated, each of 3 hp whereas one pump of 5 hp was operated with solar power. On an average the uniformity coefficient of surface and sub-surface drip irrigation system for brinjal was found to be 83.6% and 73.2% respectively. The plugged emitters in sub surface drip irrigation were the main causes of lower uniformity coefficient.
