The guava is a plant originary from tropical region of Americas and although it is a rustic plant it is demanding in nutrients. During the phase of vegetative growth the sequence of requirement of the macronutrients is N, P, K and Ca. This way, an experiment was carried out in order to evaluate the influence of substrate and phosphorus fertilization on the initial growth and mineral composition of `Paluma' guava seedling. It were evaluated 18 substrate, resultants of the combination of soil varying from 0% to 100%, sand from 0% to 100% and manure from 0% to 60%, which were fertilized with three doses of simple superphosphate (0, 6 and 12 g dm-3). The treatments were distributed in randomized block design, with three repetitions and each plot was constituted of two bags containing two seedling. It was evaluated each 30 days the height of the seedling and the stem diameter. At the end of the experiment it was evaluated the shoot and root growth. The substrate consisting of 68% of soil and 32% of manure, with 12 g dm-3 of simple superphosphate, proved to be more efficient for the seedling formation of `Paluma' guave.Keywords: Psidium guajava, mixtures, manure bovine, phosphorus. |
