RODRIGUES, Maria Geralda Vilela; RUGGIERO, Carlos; NATALE, William  e  PACHECO, Dilermando Dourado. 'Prata-anã' banana plant nutrition and production fertilized with zinc and boron via rhizoma. Rev. Bras. Frutic. [online]. 2007, vol.29, n.3, pp.645-651. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452007000300042.

It was installed one experiment in Jaíba-MG in a 6.6 year-old banana plantation, conducted for three consecutive productive cycles, aiming to evaluate the effect of different proportions of zinc and boron applied directly in the cut off seedling, under the nutrition of the plants and in the production of 'Prata Anã' banana plant. It was used the "lurdinha" cut off to extract the apical vital point of a germination, which was cut near the soil, in such a way that it remained an opening where the fertilizer was applied. It was utilized the entirely casual experimental delineation, with 10 repetitions of one plant, and with 20 resultant treatments of a complete factorial between 5 proportions of Zinc (0; 2.5; 5.0; 7.5 and 10.0 g of year-1 plant-1 Zinc) x 4 proportions of boron (0; 0.68; 1.36 and 2.04 g year-1 plant-1 Boron). The fertilizers promoted some alterations in the foliar contents of nutrients, however it happened without enough magnitude to alter the nutritional condition when it is considered the bands of sufficiency. Although the Zinc interfered in the production, this was in statistics the same when compared to the evidence (zero proportion) and the biggest proportion.
