Abstract Advances in production systems always aim at finding alternatives to improve crop productivity. One of the recent practices adopted in commercial banana and plantain plantations refers to the application of liquid fertilizers in bunches in order to increase productivity. This research aimed at verifying whether the use of biofertilizers based on pure vinasse or associated with other chemical fertilizers would provide morphophysiological changes in fruits or increase the productivity of ‘Terra Maranhão’ plantain cultivars. In order to carry out this project, a randomized block design with 6 treatments and 3 replicates was set up in a commercial crop and the postharvest production and quality characteristics of ‘Terra Maranhão’ plantain fruits were evaluated. The results showed that the morphophysiological characteristics of freshly harvested fruits that impact productivity such as the fruit weight and bunch weight were affected by treatments, as the postharvest characteristics of ripe fruits were little affected by the application of fertilizers in bunches, except for the SST content. It could be concluded that the crop yield increased significantly by 17% when using mixture of vinasse, potassium chloride and urea; however, this treatment caused significant reduction of 1.3 ºBrix compared to control.
