However, it depends on a better understanding of the nutritional requirements of these species. It aims to assess the nutritional aspects and effects of nutrients in the absence of development of Caryocar brasiliense Camb. An experiment was conducted in pots, red-yellow Oxisol substrate of low fertility in the greenhouse. 12 treatments were employed under the technique of the missing nutrient in fully randomized block design with eight replicates. The following treatments were applied: 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 air shoot and root system. Samples were dried at70 ° C, weighed and determined the levels of nutrients in shoot dry matter. According to the results concluded that the omission of Zn, Mg and K do not affect height growth of Caryocar brasiliense seedlings; during the absence of nutrients affect the development of plants in diameter Caryocar brasiliense, the total dry matter is not affected by the omission of nutrients; root / shoot ratio shows that the species is adapted to soils with low pH and low phosphorus levels; Caryocar brasiliense species show low nutritional requirements during formation process of seedlings, although the results may have been masked by the reservations contained in the seeds; nutrient content in pequi shoot dry biomass is low, indicating low nutritional requirements of the species. |
