Uso de água residuária doméstica associada a esterco caprino no desenvolvimento de mudas de mamoeiro.

Abstract

The reuse of wastewater can provide sustainable irrigated agriculture, minimizing the consumption of drinking water and also providing nutrients for plants, enabling the reduction of chemical fertilizer applied to the soil, becoming an economical, practical and viable strategy for water conservation and production of fruit species seedlings, contributing to a balanced production system with a tendency towards environmental sustainability. Thus, the development of papaya seedlings of the cultivar formosa irrigated with treated domestic wastewater, well water and fertilization with different proportions of goat manure in a protected environment was evaluated. The experimental units were distributed in a randomized experimental design in a 5 x 2 factorial scheme, with 3 replications, being five doses of goat manure (0%, 20%, 40%, 60% and 80%), and two qualities of water from irrigation (well water - AP and treated domestic wastewater - AR). At 20 days, the initial seedling development variables (plant height, stem diameter, number of leaves, root length and leaf area) were analyzed. The satisfactory development of papaya seedlings occurred when domestic treated wastewater was applied. The substrate containing the doses of 60% and 80% provided better development of papaya seedlings.
