The banana tree is cultivated in a total area of 456 thousand hectares in Brazil, distributed among all the Federative Units, reaching a production of 6.63 million tons. The planted area varies between 174 ha in the Federal District and 64.9 thousand ha in the State of Bahia and the productivity between 24.8 tons per ha in the state of Rio Grande do Norte and 7.9 tons per ha in the State of Rio de Janeiro.

According to a survey by the IBGE, in the State of Amapá in 2017, among the 3,038 thousand agricultural establishments that had 50 or more feet of permanent crops, a total of 1,460 thousand had the banana product as a permanent crop. The banana tree is a culture of significant importance for the State of Amapá, given that it is a product that is recurrently observed in fairs, supermarkets and homes. In fact, it can be said with relative certainty that bananas are present in approximately 100% of the places mentioned.

Being a crop with high nutritional requirements, requiring an annual supply of around 200 kg ha of nitrogen, 200 kg ha of potassium and 50 kg ha of phosphorus in the production phase, the optimization of banana nutrition is
permanently relevant. In this context, the overall objective of the project is to assess the symbiotic efficiency of nitrogen-fixing bacteria and their compatibility with organic and organomineral fertilization in banana plantations. The project has financial support from the Agrisus Foundation and will run from 2022 to 2024.
