Analysis of dragon planting productivity as a production function in Ham Thuan Nam District, Binh Thuan Province

Abstract

Productivity in agriculture is an important indicator of the economy in general, and dragon fruit productivity in particular. To identify and analyze the factors affecting productivity, the research team collected data from dragon fruit farmers in Ham Thuan Nam District, Binh Thuan Province, to estimate the dragon fruit production function using the least error sum of squares method; a Cobb-Douglas Production Function was built. In this model, the dependent variable is dragon fruit yield, which is influenced by factors including nitrogen fertilizer, labor for care, manure, type of dragon fruit, electricity costs for off-season work, potassium fertilizer, phosphate fertilizer, planting area size, and pesticides. Testing the violation of the model's hypotheses has shown the above factors have an impact on productivity. Based on this, the important influence of these factors on productivity was identified as a basis to propose recommendations to improve farmers' productivity.
