Previous issue date: 2017-03-31 / Avaliou-se a produtividade, a biofortificação e a trofobiose nas espécies de feijão Phaseolus vulgaris L. e Vigna unguiculata (L) Walp., cultivadas com efluente e lodo de uma Estação de Tratamento de Esgotos Domésticos (ETE). A ETE é formada por reator UASB seguido de lagoa de polimento e filtros de pedra. O experimento com 10 tratamentos e 3 repetições cada, foi montado em blocos inteiramente casualizados no sistema fatorial 10 x 2. Os tratamentos T0, T1, T2 e T3 consistiram, respectivamente, na irrigação com água de abastecimento, água + adição de fertilizantes (NPK), água + inoculação com bacteria Rhizobium e água + inoculação com Rhizobium + PK. Os tratamentos T4, T5 e T6 consistiram, respectivamente, na irrigação com efluente da ETE, efluente + Rhizobium e efluente + Rhizobium + PK. Os tratamentos T7, T8 e T9 consistiram no uso de lodo do UASB, lodo + Rhizobium e lodo + Rhizobium + PK. Cada vaso contendo 10 kg de solo foi usado para cultivar 2 plantas, com irrigação controlada por peso. Dentre os tratamentos que apresentaram os melhores resultados de produtividade, biofortificação e baixo teor de substâncias solúveis nas folhas (combatendo a incidência de pragas), o tratamento T7 (somente com lodo) foi o grande destaque. O tratamento T4 (somente com efluente) obteve resultados bem melhores que o tratamento testemunha T0. Dessa forma, o uso do lodo e efluente apresentaram grande viabilidade no cultivo das espécies de feijão P. vulgaris L. e V. unguiculata. / The productivity, the biofortifying and the trofobiose were analyzed on two beans species: Phaseolus vulgaris L. and Vigna unguiculata (L) Walp, were cultivated with domestic sewage effluent and sludge from a treatment plant which is composed by an UASB reactor, a polishing pond and stone filters. The experiment consisted of ten treatments with three repetitions each, and was conducted in completely randomized resulting in a factorial system of 10 x 2. Treatments T0, T1, T2 and T3 consisted of using water supply, water + fertilizing (NPK), water + Rhizobium bacteria inoculation and water + Rhizobium + PK, respectively; treatments T4, T5 and T6, of effluent, effluent + Rhizobium and effluent + Rhizobium +PK, respectively; and treatments T7, T8 and T9, of UASB sludge, sludge + Rhizobium and sludge + Rhizobium + PK), respectively. Each vase, filled with 10 kg of soil, was used to cultivate two plants, with controlled irrigation by weight. Among the treatments that presented the best results of productivity, biofortification and low content of soluble substances in the leaves combating the incidence of pests, T7 treatment with sludge alone was of the best performance. The T4 with effluent alone showed better results than the T0 treatment. Therefore, the use of sludge and effluent showed to be very viable on the cultivation of the two beans, P. vulgaris L. and V. unguiculata.
