The objective of this study was to evaluate the effect of ice cream raw effluent doses on consumption and vegetative development of cherry tomato under hydroponic system. The experiment was conducted in completely randomized design with six treatments and four replications. Treatments consisted of 5 different levels of effluent (0, 25, 50, 75 and 100%) complemented with the amount of nutrient recommended for growing tomatoes and 100% of effluent without nutrient complementation. Increasing doses of effluent provided linear reduction in water consumption.Addition of effluent in proportion of 25% provided best production results. Addition up to 50% ice cream effluent to nutrient solution allowed growth of cherry tomato without yield reduction providing better efficiency of water use in terms of dry weight of shoots and fruit production as well as maximum substitution of soluble mineral fertilizers in nutrient solution.
