Abstract:

One of the main agricultural industries in the Philippines, particularly in Central Luzon, has been rice production. This study investigated the influences and determinants on national rice production. Labor, capital, credit to agriculture, spending, irrigated areas, land, and fertilizer are the relevant factors. The Cobb-Douglas Production Function was used in the study. The relationship between production output and production inputs (factors) is modeled by the Cobb-Douglas Production Function. It is used to calculate ratios of inputs to one another for efficient production and to estimate the technological change in production methods. It measured the elasticity, marginal rate of contribution, and marginal returns of capital, labor, fertilizer, irrigation, production loan, farm area, and government spending to the total agricultural rice productivity of the Philippines. This paper also analyzed the production in terms of its input and output and estimated the relationship between each input and output. The results of this study showed that capital, expenditure, and land do not significantly affect the volumes of production of rice. While labor, credit to agriculture, irrigated areas, and fertilizer significantly affect the volume of production of rice.
