- Abstract
The use of treated wastewater in the irrigation of agricultural crops is indicated as an alternative to mitigate the problem of water scarcity. Thus, this study aimed to evaluate the growth and phytomass of sweet potatoes irrigated with treated wastewater. The study was conducted in a greenhouse belonging to the academic unit of agricultural engineering at the Federal University of Campina Grande, in a randomized block design and 3x2 factorial scheme, with five replications. The factors consisted of three water qualities (T1 = water from a cistern; T2 = water treated by wetland and T3 = water treated by UASB + wetland), and two sweet potato cultivars (Campina and Granfina). At the end of the cultivation cycle, the number of leaves (NF), number of branches (NR), leaf area (AF), stem diameter (DC), fresh leaf phytomass (FFF), fresh branch phytomass (FFR), dry leaf phytomass (FSF) and dry branch phytomass (FSR) were evaluated. The results obtained show that the variables (NF), (NR), (AF), (FFF), (FSF) and (FSR) were significantly influenced by the cultivars. Wastewater treated for irrigation of sweet potatoes can be used without loss of growth and phytomass characteristics.
