Drip fertigation is the technique of application of suitable quality of water for irrigation purpose along with fertilizer to provide water and fertilizer efficient condition for growth and development of plants. A study on field evaluation of drip fertigation system for Okra crop was conducted under sandy loam soil conditions of Ludhiana district of Punjab state (India). There were nine treatments consisting of combination of three fertilizer levels (60%, 80% and 100% of RDF) and three irrigation levels (0.6, 0.8 and 1.0 of IW/CPE ratio). Emitter discharge measured at 15 days interval for the entire crop season was used to check the performance of drip fertigation system by evaluating Christiansen Uniformity Coefficient (CUC) and Lower Quartile Distribution Uniformity (LQDU).Emitter discharge, CUC and LQDU varied from 0.81 lph to 1.2 lph, 92.1% to 95.6% and 83.1% to 88.7% respectively. It was observed that there was non-significant variation of emitter discharge, CUC and LQDU within the treatments although Emitter discharge, CUC and LQDU decreased with time intervals.
