EVALUATION OF WATER QUALITY FOR IRRIGATION IN

Given the quest for sustainable development and rational use of resources natural, the implementation of irrigation systems becomes a necessity in regions of seasonal scarcity of water and great agricultural productivity, as in case of Paraná. Thus, the objective was to evaluate the parameters Physico-chemical water quality in the city of Salto do Lontra –Paraná. The Physical-chemical analysis included: pH, Electrical Conductivity (EC), Total Solids Soluble (STS), nitrate (N-NO3), RAS, Sodium (Na++), chlorine (Cl-) and bicarbonate (HCO3), being held in 40 properties, according to APHA (1998). The analysis Statistical surveys were performed using the Minitab 15 software. The results in the study period, showed average values in the range limits recommended by FAO for the use ofirrigation water considering all parameters measured and there was no restrictions on water use in irrigation.
