Growing, Production and Quality of Thornless Cactus Irrigated With Dairies Effluent

摘要

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.
