RESUMO:

The banana stands out as one of the leading fruits in world agricultural production and trade. Brazil is the world's fourth largest producer of this fruit, accounting for about 5.8% of production. However, it is not known how much of this total corresponds to the varieties of the Terra (plane tree) group. In commercial crops the spacing used has been from 3.0 x 4.0 m (833 plants ha-1) to 3.0 x 2.0 m (1,666 plants ha-1). The modification of the management system with high density planting has proved to be profitable, reducing production costs due to higher yields due to the greater number of bunches harvested per unit area, providing favorable results to the farmer. Therefore, the objective of this work was to evaluate the productivity, fruit quality and profitability of the banana Farta Velhaco under different planting densities. The experiment was conducted in the experimental area of fruit growing at the State University of Mato Grosso - Unemat, in Tangará da Serra - MT. The experimental design used was randomized blocks, with four treatments and four replications. The treatments consisted of four double row row spacing, being 4.0x2.0x1.0m (3,333 plants ha-1), 4.0x2.0x1.5m (2,222 plants ha-1), 4.0x2.0x2.0m (1,666 plants ha-1) and 4.0x2.0x2.5m (1,333 plants ha-1). The plants were evaluated in the flowering phase, through the characteristics of plant height, circumference of the pseudostem, number of active leaves, percentage of increase in plant height and circumference of the pseudostem. The phenological characteristics correspond to the duration of the vegetative, productive and total cycle. At harvest, productivity was evaluated and after ripening the clusters, the quality of the fruits. In addition to these characteristics, the production costs and profitability of the banana crop during the entire crop cycle were determined. At flowering, it was found that the planting spacing did not influence the characteristics of the pseudostem circumference, number of active leaves, number of days from planting to flowering, percentage of plant height and pseudostem circumference. It only showed a significant difference for the plant height characteristic, where there was an increase in the height values, as the planting spacing was reduced. Regarding the total cost of production (CTP) estimated for the banana, it was R $ 19,727, 46 (1,333 plants ha-1) to R $ 31,744.66 (3,333 plants ha-1), with the highest CTP values in the denser planting, with 3,333 plants ha-1, thus requiring greater financial investment by the banana grower. However, at this stage of the research there is still no data on bunches production and fruit quality, so there is still no revenue, only costs.
