A technical report was conducted for checking performance assessment of drip irrigation system which was used for cultivating tomato in premises of the Centre of Excellence Protected Cultivation, Raipur (Chhattisgarh). A uniformity coefficient was found for drip irrigation system which ranges from 73.2 % to 83.6%. The coefficient of variance varies between 0.0055 to 0.0068 for the measured discharges of four laterals laid in the field. It shows that there is the least variation between the obtained flow rates of different laterals under study. The application efficiency of four different lateral lines operating at a pressure of 1.25 kg/cm2 was calculated and it found to be more than 90.00 %, excluding lateral line (L2). Almost same amount of flow variation (8-9%) is found in lateral lines L1, L3 and L4, although Lateral line (L2) discharges 11.00 % more water among others. The maximum flow variation was found for the lateral line (L3) and the least flow variation was for the lateral line (L1). The distribution efficiency of all the laterals was found more than 97.45 %.
