BRS platinum banana trees grown with macaxisto rock powder

Abstract

The banana (Musa spp.) is one of the fruits most consumed by the population and has great importance in fruit growing. It is a very nutritionally demanding crop and depends on an adequate ratio of nutrients for its development. The objective of the research was to evaluate the development and productivity of the banana tree "BRS Platina" with the use of micaxiste rock powder (soil remineralizer) in the first cultivation cycle. The experiment was conducted at the Federal Institute of Goiano – Campus Morrinhos (-17◦48'50.4" S, 49◦12'16.5'' W, altitude of 902 meters) in a randomized block design. The treatments consisted of fertilization with and without micaxiste rock powder, with seven plants per plot and 12 replications. The plants of the first cycle (mother) were evaluated at 230, 275 and 320 days after transplanting the seedlings. Plant height, pseudostem circumference and number of leaves were measured. When they entered the productive phase and reached the point of harvest, the mass of the bunch, the number of feathers and bananas were evaluated, performing manual counting. The fertilization with micaxiste rock powder favored the vegetative development of the plants, but did not significantly influence the productivity of banana trees "BRS Platina".
