Influência das fontes hídricas nas características agronômicas e microbiológicas da cultura do repolho roxo (Brassica oleracea var. capitata f. rubra) irrigado com água de abastecimento humano e efluente tratado

Abstract

The scarcity of the planet's water has been provoking debates and research in the search for alternatives to face this problem. The use of treated wastewater for irrigation has been shown to be a viable alternative, as it presents significant results in relation to water consumption and in the awakening of the collective consciousness for the responsible treatment of the planet's finite goods. Thus, this work aims to analyze the use of effluents in agronomic characteristics and to verify the microbiological characteristics of cabbage (Brassica oleracea var. Capitata f. rubra) and the viability for human consumption. The research was developed in a protected environment, located at the Federal University of Sergipe. The experimental design was in Entirely Randomized (DIC), consisting of 3 treatments (T1: irrigated 100% with drinking water from the Sanitation Company of Sergipe – DESO; T2: irrigated with 50% of drinking water from the Sergipe Sanitation Company – DESO and 50% with effluent; T3: 100% irrigated with effluent) and 15 replicates of each treatment totaling 45 pots. It was observed that the use of wastewater influenced the agronomic characteristics of the cabbage crop (fresh mass and dry mass), with the exception of the variable head diameter. The results of the microbiological characteristics met the standards with absence for Salmonella and values below for Escherichia coli.
