Abstract

The micronutrientes Zn and B are frequently in deficient concentrations in banana plantations in the Brazil and world . Nitrogen is an important nutrient in the manuring of the banana plantation in production. To minimize that problem, the supply of B is recommended (boric acid) in the rhizome of the thinned sprout, to improve the nutrition and to increase the production of the banana 'Prata-Anã', under irrigation. Then the fertilizers can be supplied by occasion of the rough-hewing of the banana plantation, through perforation done with the 'lurdinha' apparathus. In hypothesis, the applied nutrients in the open hole to thin the sprout not wanted enter in contact with the plant-mother's rhizome and, through this, they are absorbed and they start to circulate in the system of all the plants of the 'family' that be interconnected. In spite of already to be recommended in practice this method of manuring of the banana plantation, there is still no confirmation of the hypothesis in the which the technique is based. The isotope methodology is an useful tool that can confirm or to refute the hypothesis, because it allows to verify the distribution of the nutrient in the banana plant. (AU)
