Agronomic behavior of gladiolus in organic substrates with wastewater reuse

Ítalo Dourado Teixeira, Sérgio Oliveira Pinto de Queiroz, Carlos Alberto Aragão, Alessandro Carlos Mesquita


This study aimed to assess the technical feasibility of effluent reuse and recycling of organic substrates in the production of gladiolus. We adopted a completely randomized design in a split-plot, and the plots three qualities water (river water with Hoagland’s solution; treated effluent in stabilization pond; treated effluent in stabilization pond and disinfected) and the subplots organic substrates (pine bark, coir, bagasse), repeated five times. Were characterized physico-chemical water and each substrate, the beginning and end of two growing seasons. The variables evaluated were: number of tillers, plant height, total production; flower stem length, number of flowers, time to first harvest, total cycle time, fresh and dry mass of the area. The reuse of effluent resulted in agronomic performance equal or superior to that obtained by the use of nutrient solution and the substrate base bagasse promoted agronomic performance inferior to the other substrates evaluated.
