Abstract

The growing concern for the preservation of water quality associated with large water demand by irrigated crops has led researchers to search for alternative sources for production. Irrigation with wastewater is an alternative to replace quality water, allows the maintenance of soil moisture, can be a source of nutrients, and prevent the risk of contamination of water resources.The processing of animal products and vegetable by agribusiness generates liquid waste rich in organic matter, nutrients and salts that although post-treatment, still have potential for pollution to waters, mainly by the presence of sources of nitrogen and phosphorus.Providing these effluents to crops must be evaluated in terms of nutritional and microbiological testing to ensure productivity and bacteriological quality of the plants.The goal of this research is to evaluate the end product of beet cultivation in protected cultivation under drip irrigation with effluent generated at the dairy USP Pirassununga School, post-treatment, as their production characteristics, microbiological quality and technology. The treatments are: (i) Irrigation with treated wastewater by anaerobic sequencing batch reactors (ii) irrigation with treated wastewater by aerobic reactor operated in sequencing batch (iii) surface water. Three different depths of effluent will be applied to each of the treatments (50%, 100% and 150% of evapotranspiration). The cultivation is carried out in two different seasons, spring-summer and autumn-winter. (AU)
