Short CommunicationIn the production of plantains and bananas, as in most of agricultural production systems, large amounts of residues or waste are generated, such as reject fruits, pseudo-stems, leaf litter and rachis, mainly. In this regard, investigations carried out in Cuba, considering an average value into the percentage of rachis weight (11%) and its representativeness at the annual level production of plantains and bananas in the country (675,405.1 t), can mean values of 74,294.6 t of cluster rachis. These data reaffirm that the production of plantains and bananas in Cuba, causes a considerable amount of organic waste, which are not properly used and they could be reused [1].The Food and Agriculture Organization of the United Nations (FAO) promotes experiences in Latin America and the Caribbean, focused at reducing food loss and waste, and the use of by-products or residues, which contribute to the improvement of environmental health conditions in the context of integrated and efficient productive systems [2]. Leachates from edible musaceae (plantains and bananas) are plant extracts, obtained by decomposition of harvest residues [3,4]. The rachis leachate (flower peduncle, also known as pinzote or stem, has a helical shape and it is the responsible for the support of clusters), as it is a product of the same plant, it has essential nutrients (N, K, Fe, Mn, Na, Cu) that can be reused for the crop itself [5][6][7]. These plant extracts applied to banana seedlings under nursery conditions, have proven to be effective in the growth of them, with a significant increase in the variables (height, number of leaves, as well as the total length and fresh and dry weight of the roots) [8,9]. Besides the nutritional value of this extract of plants, its potential as a pest and pathogen controller has been studied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
