“…The dose of 692.4 m 3 ha -1 of DWW (T4) significantly increased the PROD, FM, DM and PH variables, resulting in a major of 28.17 Mg ha -1 , 2.82 kg m -2 , 0.21 kg m -2 and 0.45 m, and an increasing of 459, 460, 429 and 149%, respectively, about the thornless cactus responses under control treatment (T1). Mathiyarasu et al (2017) used an 800 mm -1 blade water of slaughterhouse and domestic sewage wastewater, and obtained the productivity of 8.4 and 4.4 Mg ha -1 DM of sunflower and alfalfa, respectively. While Bezerra et al (2017) obtained a productivity of 2.28 Mg ha -1 DM of Marandu grass (Brachiaria brizantha cv.…”

The environmental pollution coming from dairies industries are the most hazardous of the economy sector due to the great amount of garbage produced. This work aimed it evaluating the dairies effluent on the morphometric, productive, bromatological, and nutritional effects of the thornless cactus. One trial was carried out it the Water Reuse Experimental Station during the period from April to December 2015. The experiment was carried out in randomized blocks design, with five treatments and five replications, totaling 25 experimental units. The treatments were irrigation with water of well (T1), irrigation with 10% of annual dose plus water of well (T2), irrigation with 20% of annual dose plus water of well (T3), irrigation with 30% of annual dose plus water of well (T4), and irrigation with 40% of annual dose plus water of well (T5). The growth parameteres determinations parameteres (production and quality) of thornless cactus were achieved at 240 days after planting. The highest productivity (28.2 Mg ha-1) was achieved with the treatment T4. The nitrogen concentrations were significative to thornless cactus, whereas the treatment T4 increased mostly the Nitrogen content in the plants. Then, the T4 treatment predominated, since it enhanced the crop productivity about crude protein and Nitrogen contents.

Using wastewater in agriculture is a desirable alternative source of irrigation and is gaining attraction worldwide. Therefore, this study was designed to assess the effect of treated municipal wastewater (TWW) and groundwater (GW), along with half and full doses of the recommended NPK dose on the plant growth, total biomass, gross energy, and macro- and trace element content and uptake of safflower (Carthamus tinctorius L.), canola (Brassica napus L.), and triticale (X Triticosecale Wittmack) grown in old and virgin soil as potential bioenergy crops. The results showed that crops planted in old or virgin soil irrigated with TWW had higher values of plant height, leaf area per plant, total chlorophyll content, total biomass, and gross and net energy contents compared to those irrigated with GW grown in virgin soil. Similarly, crops grown in old soil irrigated with TWW showed higher concentrations in dry matter and uptake for both macronutrients (N, P, and K) and trace elements (B, Zn, Mn, Cu, Cd, Pb, and Ni) compared to those planted in virgin soil and irrigated with GW. Furthermore, the application of the recommended half dose of NPK in old and virgin soil irrigated with TWW showed occasionally comparable results to that of a full recommended dose of NPK for most of the measured parameters. Importantly, the recommended half dose applied to old soil irrigated with TWW resulted in a significant improvement in all measured parameters compared to virgin soil irrigated with GW, along with a full recommended dose of NPK. Briefly, TWW can be used to irrigate crops grown for bioenergy purposes, since it did not pose any harmful effect for energy crops. In addition, it provides additional nutrients to soil and thus decreases the required rate of synthetic fertilizer by up to 50% without any significant decreases in the final production of crops.
