Abstract

The objective of the work was to analyze the technical efficiency of yam cultivation in producing areas of the Caribbean Region. The data were obtained through 98 structured surveys applied to experienced farmers, which included socioeconomic information such as: age, schooling, size of the cultivated area, physical crop yields, and production destination. The sampling technique was simple random applied at random. The data were analyzed in the SPSS program and techniques such as descriptive statistics and measures of central tendency were used. Likewise, a Cobb-Douglas type econometric model was designed that allows the formulation of a production function and the estimation of the value of the parameters. The results show that production efficiency is low due to the underutilization of some factors such as labor, which is 78 wages on average, which are excessive to cultivate one hectare of yams; in addition, they use fertilizer without soil analysis and without taking into account the nutritional requirements of the crop, the seed as an important factor contributes to the increase in production with a coefficient of 0.033881 which means that if its quality is improved, efficiency can be increased. Experience and schooling are the elements that most contribute to the efficiency of yam cultivation. It is concluded that farmers can increase their productivity with better use of resources.
