Utilization of juçara seed as source of substrate in the production of vegetable seedlings

Abstract

The objective of this paper was to evaluate the use of juçara seed, as source of substrate to production of vegetable seedlings. The experiments were conducted in a completely randomized design with four treatments and four repetitions for each treatment. The treatments were: fermented triturated juçara seed, compound based on triturated juçara seed and cattle manure; triturated carbonized juçara seed; and Basaplant commercial substrate. The vegetable tested were: a) fruits vegetable: okra (Abelmoschus esculentus) e tomato (Lycopersicon esculentum); b) flower vegetable: cauliflower (Brassica oleracea var. botrytis); c) leafy vegetable: lettuce (Lactuca sativa). The evaluations were: number of leaves, leaf area, fresh and dry weight of shoot, root and the total number of vegetable seedlings produced. The substrate 1 (fermented triturated juçara seed) was the best for production of tomato seedlings, okra and cauliflower, while the substrate 2 (compound based on triturated juçara and manure) showed the best results in the production of lettuce seedlings.
