Abstract

In the semi-arid region of Brazil due to water scarcity, the use of alternative water sources is of vital importance, such as the use of saline waters and treated sewage effluents. Therefore, in the present work, the growth of sunflower plants irrigated with tap water and treated domestic sewage effluent, associated with organic fertilization was evaluated. The research was carried out in a protected environment at the Federal University of Campina Grande, Campus I, Campina Grande, PB. A completely randomized experimental design with factorial arrangement was used (4 x 2) + 2, with 5 repetitions. the treatments consisted of organic manure dosages (7.5, 10, 12.5 and 15% of manure on a weight basis) and two water sources (supply water and treated domestic sewage effluent). According to the results obtained, it can be indicated that the use of domestic sewage effluent for sunflower irrigation increased sunflower growth in relation to the use of water supply. The application of manure doses of 12.5 and 15% improved the early growth of the sunflower, with significant increases in the growth variables.
