Development and nutritional quality of hancornia speciosa seedlings cultivated in mixture containing coconut fiber and fertilized with phosphorus

In order to produce good quality seedlings it is necessary to use a mixture that presents appropriate physical, chemical and biological properties, which supplies the necessary conditions for the germination and the seedling's establishment. This experiment was carried out at the Agricultural Sciences Center, Paraíba Federal University (Brazil), whose objective was to evaluate the growth and the mineral composition of Hancornia speciosa seedlings in substrata composed by concentrations of coconut fiber from 0% to 40%, manure bovine from 0% to 25%, soil from 25% to 70%, sand 15% and triple superphosphate between 0 and 11 g dm-3. The soil and coconut fiber had beneficial effects on the H. speciosa seedlings with the increase of its concentrations in the mixture. The addition of the manure and the doses of triple superphosphate provoked a decrease in the matter and in the foliate area in the H. speciosa seedlings. There was an increase of the nutrients content in the seedlings in which there was an increase of the manure concentration in the mixture. It is recommended to use the concentrations of 14% of manure, 56% of soil, 15% of coconut fiber, 15% of sand and 4 g dm-3 of triple superphosphate, for the maximum estimated values of growth and nutritional composition.
