- Abstract
Since agriculture is the activity that consumes most water, there is a need to reuse water in this practice. The objective of this work was to evaluate the influence of the application of different percentages of wastewater treated by solar radiation (AR-TRS) in scallion 'all-year' culture and to quantify E. coli in the culture. The experiment was conducted at the Department of Rural Engineering of FCA / UNESP, Botucatu-SP. The statistical design was randomized with five replicates and five treatments, 0, 25, 50, 75 and 100% of AR-TRS in the total irrigation depth, completing treatments with 100, 75, 50, 25 and 0% of supply water (AAF). The results demonstrate the influence of ARD-TRS in the parameters studied: plant height, number of stalks, diameter of the largest stem, number of tillers, diameter of the largest till, diameter of the clump, mean fresh and dry matter, except for E. coli, which showed no influence, but a possible cross-contamination in a sample was observed. In conclusion, the use of ARD-TRS is welcome because it brings productive increases to the culture, moreover, its E. coli values are within the standards defined by the World Health Organization.
