“…Freitas et al [13] employed wastewater in cultivating cowpea (Vigna unguiculata (L.) Walp.) and found a high yield of 935.8 kg ha −1 in treatments irrigated with treated domestic sewage, which was significantly different from the treatments irrigated with well water, 842.4 kg ha −1 .…”

“…Sousa Neto et al [38] found that treated domestic effluent completely replaced mineral fertiliser when growing cotton. Freitas et al [13], growing cowpea (Vigna unguiculata (L.) Walp.) irrigated with treated domestic sewage, pointed out that it can replace commercial fertilisers by up to 100%.…”

“…Freitas et al [13] showed that the use of wastewater has a positive influence on the production variables of cowpea (Vigna unguiculata (L.) Walp.). Hermman et al [44] reported that sunflower was more productive when fertilised with treated domestic sewage than with NPK mineral fertiliser.…”

“…As such, the use of wastewater in agriculture to reduce the consumption of drinking water and the environmental impact of inappropriate waste disposal is a worldwide trend. Freitas et al [13], in research with wastewater associated with mineral fertiliser in cowpea (Vigna unguiculata (L.) Walp.) cultivation, demonstrated the possibility of completely replacing mineral fertilisers.…”

The bean is an important crop in feeding the global population. In the northeast of Brazil, it is of particular importance, since it is a staple food, which also generates employment and income. The low productivity of the northeast in recent years due to the water crisis combined with the cost of energy has compromised technical and economic viability. This study aimed to evaluate production parameters of cowpea (Vigna unguiculata (L.) Walp.) under different alternative production systems in the northeast of Brazil. The study was carried out in the experimental area of the sewage treatment plant (STP) in the district of Tianguá, Ceará. The experiment comprised six production systems (treatments) divided into split plots distributed in a completely randomised design with fifteen replications. The systems irrigated with wastewater and amended with different of fertilisers were no fertiliser (S2A0), mineral fertiliser (S2A1) and organic fertiliser (S2A2), as well as systems irrigated with drinking (S1A0, S1A1 and S1A2). It was found that under the systems irrigated with wastewater, the average productivity was 1468.8 kg ha−1, whereas under the systems irrigated with drinking water, it was 984.1 kg ha−1. The production systems that used wastewater (S2A0, S2A1 and S2A2) resulted in greater productivity compared to the production models irrigated with drinking water with organic fertiliser (S1A2) and with no fertiliser (S1A0). All the production models irrigated with wastewater yielded similar results to the conventional system with mineral fertiliser, showing that treated wastewater contains sufficient nutrients to potentially replace mineral fertilisers in cowpea production in the northeast of Brazil. The use of treated domestic effluent increases the productivity of irrigated crops.

O reuso de água apresenta-se como alternativa viável ambiental e economicamente na produção agrícola. Nesse contexto objetivou-se avaliar a produtividade do maracujazeiro amarelo, bem como as alterações proporcionadas no solo em função de diferentes níveis de reposição da evapotranspiração da cultura, utilizando como fontes hídricas o esgoto doméstico tratado e água de poço. O experimento foi conduzido em delineamento de blocos ao acaso (DBC) com esquema de parcelas subdivididas com quatro repetições. As parcelas foram constituídas de duas fontes hídricas (efluente de esgoto doméstico tratado e água de poço artesiano) e, nas subparcelas, cinco lâminas de irrigação baseadas na evapotranspiração da cultura (50; 75; 100; 125 e 150% da ETc). A massa fresca do fruto e diâmetro de fruto aumentaram significativamente em função do uso de água de poço como fonte hídrica. O aumento da disponibilidade hídrica proporcionou incrementos no número de frutos e na produtividade média da cultura. A utilização de efluente de esgoto doméstico tratado não promoveu alterações indesejáveis nos parâmetros químicos avaliados, possibilitando produtividade satisfatória e ambientalmente viável, podendo ainda substituir parcialmente a adubação química.

The water deficit in arid and semiarid regions and the high cost of fertilizers are factors for the study of application of sewage on agricultural crops. Therefore, the objective of this study was to evaluate the effect of application of different doses of treated sewage from the tertiary treatment (TS-3), and mineral fertilizer on the yield and production components of common bean plants. The experiment was conducted in Janaúba, MG, Brazil, using a randomized block design, with four repetitions, in a split-plot scheme, with five treatments in the plots consisting of potassium (K2O) applications at the dose required by common bean plants via clear water + 40 kg ha-1 of K2O mineral (Control), and TS-3 applications supplying 20, 40, 60 and 80 kg ha-1 of K2O, and two cultivars in the subplots, BRS-MG-Madreperola and Ouro Negro. The cultivar Ouro Negro was more responsive than the cultivar BRS-MG-Madreperola to the different TS-3 doses and mineral fertilizer regarding their leaf, stem, and shoot dry weights, and their ratios. However, the highest doses of K2O via TS-3 affected negatively the grain yield in common bean plants. The dose of 20 kg ha-1 of K2O via TS-3 is the best dose for common bean plants.
