• Abstract:

  The banana (paradise muse) is one of the most important foods in the world and plays a relevant role in the food security and sovereignty of more than 400 million people, its versatility and adaptability have allowed it to be raw material for various industries, however, this crop in The rural areas of Buenaventura, Colombia are cultivated under agroforestry systems in subsistence agriculture, in slightly acidic soils and favorable environmental conditions for the presence and proliferation of pests and diseases. The objective of this work was to evaluate the effect of two fertilizers on production and phytosanitary aspects in banana (Musa paradisiaca) cultivation in Buenaventura, Colombia. Chemical fertilizer 15-15-15 was used at a dose of 100 grams/plant and the dose was increased after each application until reaching a dose of 300 grams/plants and chicken manure-based compost supplemented with Beauveria bassiana at a dose of 400 grams/plants and increased. in 100 grams after each application every 45 days. To identify the pathogen, a characterization of the symptoms presented by the affected plants was carried out. In this sense, the identification of the pests was carried out based on the observed damage and the morphological description of the captured individuals. Production was evaluated taking into account into account variables such as weight, number of bananas and number of segments per bunch. This research showed that in the study areas the pests Metamasius habitats, and Cosmopolites sordidus, and the pathology caused by Mycosphaerella sp. predominate, in addition that organic fertilization is the best alternative given its low cost, ease of obtaining and contributions it makes in improving the structure and quality of soils.
