Abstract: The study of water deficit in crops is of paramount importance, since water is a scarce resource. As well as the use of wastewater. The present investigation aimed to study the growth of the daisy under different doses of irrigation with wastewater. The study was implemented in a greenhouse, in the experimental area of the Agricultural Engineering course at the Federal University of Pampa – Campus Alegrete/RS. The experimental design was completely randomized, bifactorial (irrigation doses X concentrations of swine wastewater). There were 3 irrigation doses (100%, 70% and 30% of the vessel capacity) and 5 effluent concentrations: 100% Effluent, 50% Effluent + 50% H2O, 100% H2O, 25% Effluent + 75% H2O and 75% Effluent + 25% H2O. Each concentration consisted of four replicates. The following were evaluated weekly: stem diameter, number of nodes, number of leaves and leaf area. The best plant responses occurred for water depths around 70% of CV. The plants submitted to irrigation with effluent concentrations showed the best results. It is concluded that the use of wastewater in irrigation provided greater development for the crop under study.
