“…In the present study, the use of wastewater was associated with nutrient supply, especially nitrogen (Al-Jaboobi et al, 2014;Gatta et al, 2015;Medeiros et al, 2017Medeiros et al, , 2018, as all growth rates were higher in nitrogen associated with wastewater than in nitrogen with irrigation water, at the vegetative stage. Similar results were observed with pepper, since the use of wastewater together with nitrogen favored the growth of the plants in height, number of leaves, and leaf area (Iqbal et al, 2015). In addition to its direct effect, wastewater favored plants by releasing other nutrients such as, Mg, P, and K and increased the soil organic matter (Al-Jaboobi et al, 2014;Gatta et al, 2015;Medeiros et al, 2015).…”

“…Of late, among the several strategies, the use of wastewater in the cultivation of different agricultural crops has been widely studied (Tak, Babalola, Huyser, & Inam, 2013;Iqbal et al, 2015;Kummer, Grassi Filho, Lobo, & Lima, 2017;Medeiros et al, 2017;Medeiros et al, 2018). This type of water, when adequately treated, becomes a viable alternative, as it allows the maintenance of agricultural production and the economics of surface water in regions with water scarcity, besides providing macro and micronutrients to the plants, mainly nitrogen (Pedrero, Kalavrouziotis, Alarcón, Koukoulakis, & Asano, 2010;Iqbal et al, 2015;Medeiros, Nobre, Ferreira, Araújo, & Queiroz, 2015).…”

Water is one of the most important natural resources, especially for semiarid regions where it is very limited. Thus, some alternatives to preserve water are necessary. In this sense, we aimed to evaluate the effect of irrigation with post-treated domestic wastewater associated with different nitrogen rates on the growth of okra in the semiarid region of Brazil. The experiment was performed in the municipality of Pombal, state of Paraíba, Brazil. It was used a randomized block design with six nitrogen rates (N1 = 0, N2 = 40, N3 = 80, N4 = 120, N5 = 160, and N6 = 200 kg ha-1) and wastewater corresponding respectively to 0; 25; 50; 75; 100; and 125% of the fertilization recommendation for the okra crop. In addition to these treatments, a control was added and the plants received 100% of the recommended dose of nitrogen and they were irrigated with water (IW). The control was compared with the treatments that were irrigated with wastewater and received the minimum (0%) and the recommended (100%) doses of nitrogen fertilization. The use of treated wastewater is an excellent technique for the reuse of water in semiarid regions, but it does not fully meet the okra nitrogen requirements.

“…We verified in this study that the relative growth of plant height was influenced by the fertilization of nitrogen and phosphorus associated to wastewater, only at the vegetative stage, while leaf growth was affected at the beginning of fruiting. The plant growth was probably due to nitrogen supply, involved in cell division and stretching (Iqbal et al, 2015), and phosphorus, promoting root respiration, increasing plant growth when adequately supplied (Melo et al, 2018).…”

“…Tak, Ahmad, Babalola, and Inam (2012) report that wastewaters have a large concentration of essential nutrients to maintain soil fertility, as well as to increase growth and plant productivity. The concentration of nutrients of wastewater is important for agriculture, and when used correctly, can meet the needs of water by plants and reduce the demand for fertilizers contributing to the preservation of the environment (Iqbal et al 2015;Medeiros et al, 2018b).…”

“…Eggplant produces satisfactorily 6.41 kg of fruits per plant, using 690.04 mm during the cycle (Lima et al, 2012), what is a relatively high water volume regarding the crop cycle. A way to mitigate this problem is the use of wastewater for irrigation of plants, as reported in several studies involving different crops, such as eggplant , tomato (Gatta et al, 2015), okra (Khaleel et al, 2013;Medeiros et al, 2018a, b) and sweet pepper (Iqbal et al, 2015).…”

Wastewater use has become an alternative for agriculture in arid and semi-arid areas due to water scarcity besides providing nutrient for plants. This work aimed to evaluate the effects of the interaction of nitrogen and phosphorus doses associated with wastewater on the growth rate of eggplants in the stages of vegetative growth and beginning of fruiting in the semi-arid of Brazil. The wastewater was previously treated using sand filter with intermittent flow. The experiment consisted of a randomized block design in a 4 × 4 + 1 factorial scheme, with four replications. The factors consisted of four nitrogen doses (N1 = 0.22, N2 = 0.39, N3 = 0.56 and N4 = 0.72 g dm-3 of soil), four doses of phosphorus (P1 = 0, P2 = 1.68, P3 = 2.40 and P4 = 3.12 g dm-3 of soil), both using wastewater, and a control treatment (100% nitrogen and phosphorus using drinking water). The interaction of wastewater with nitrogen and phosphorus doses influenced all growth rates at the vegetative stage, except for the relative number of leaves. We found interaction for the relative rates of stem diameter and number and area of leaves at the beginning of the fruiting stage. Nitrogen and phosphorus doses associated with wastewater were excessive even below the recommendation for eggplant cultivation, however, in the absence of wastewater the plants reduce the growth rates of stem diameter and leaf area in the initial period of the fruiting.
