Evaluation of losses in bananas produced in the Rio Preto da Eva, Amazonas, Brazil

Abstract

Quantities and causes of banana losses produced by family farmers in a municipality of Amazonas were evaluated. Current research was conducted in the José Lindoso community, located in Rio Preto da Eva, a municipality within the Metropolitan Region of Manaus. Data were retrieved from a sample of 14 banana growers by interview and observation techniques. In the interviews, information was obtained on the management and production of banana crops, whilst collection and post-harvest procedures were monitored for observations. Data analysis was made by descriptive statistics and multiple linear regression. Most farms measured 25 ha, with banana crops ranging between 0.5 and 4 ha; ‘Thap Maeo’ was the prevalent cultivar. Results showed that management practices used in the conduction of bananas had interfered in the quality of bananas produced. Physiological, mechanical and biological damages were recorded, responsible for quantitative and qualitative losses in the field and in the storage period on the farm. There was statistical evidence that the size of the property, banana type and family, the age of cultivation, assistance and technical training were the main determinants for losses. Banana growers with older crops and those who receive Technical Assistance and Rural Extension services coupled to training courses tend to have higher loss rates. This is due to high productivity and production of crops, resulting in greater difficulties for the product´s commercialization.
