Requerimentos nutricionais de mudas de Favela, Pequi, Marolo e Barbatimão

Abstract

The establishment of fruit and medicinal species of native cerrado may soften the negative environmental aspect arising from deforestation, and improve their utilization which today is restricted to local populations. However, depends on a better understanding of the nutritional requirements of these species. Aiming to assess the nutritional aspects and effects of nutrients in the absence of development of Dimorphandra mollis Benth., Caryocar brasiliense Camb., Annona crassiflora Mart., e Stryphnodendron adstringens (Mart.) Coville. An experiment was conducted in pots, red-yellow Oxisol substrate of low fertility in the greenhouse of the Department of Forest Sciences of UFLA. 12 treatments were employed under the technique of the missing nutrient in fully randomized block design with eight repetitions. We applied the following treatments: Complete 1 (C1-fertilized with N, P, K, S, B, Cu, Fe, Zn and lime), complete 2 (C2-fertilized with N, P, K, S, Ca, Mg , B, Cu, Fe, Zn, without lime), omitting treatments complete when each of the relevant nutrients (complete 1, complete 1-K, complete -S, complete 1-P, complete 1 - B, complete 1 - Zn, complete 1 - lime, complete 2-Ca, complete 2 - Mg) and control. The plants were harvested and separated into shoot and root system. Samples were dried at 70 ° C, weighed and determined the levels of nutrients in shoot dry matter. According to the results concluded that: 1) The absence of Ca, S, the Mg and K did not affect the quality of seedlings of Favela. 2) The Pequi is a species not very demanding in their seedling stage of training, so do not require fertilizer during their training. 3) The marolo is a species that responds well to use of lime. 4) The barbatimão is a plant of slow growing and adapted to acidic environments and low-Ca do not need to set the ground for training of their seedlings.
