Treated industrial waste water from food processing plant was applied to tomato (Lycopersicum esculentum) crop through drip irrigation under different treatments. Effect of different treatments on the biometric parameter of tomato rivaled that irrigation sources have caused variation in plant height. Higher plant height was recorded under Bore Well Fresh Water (BWFW) at 15, 30, 60 and 90 DAP as compared to Treated Fruit Waste Water (TFWW). Interaction between irrigation sources and emitter did not affect plant height. Higher number of branches have been recorded under BWFW at 30, 60 and 90 DAP as compared to TFWW and under S1 type of emitter. The number of flower cluster per plant at different stages of crop growth was influenced by different irrigation treatments and different emitter type. Numerically higher number of fruit clusters per plant was recorded under BWFW as compared to TFWW. Interaction between irrigation sources and emitter did not affect the number of fruit cluster per plant as it was non significant at all the time periods. The weight per fruit of tomato was not affected by irrigation source and type of emitter. The study concluded that treated waste water could be used safely for tomato crop under drip irrigation.
