Reduction of production factors in pesticide - free vegetables for farmers in Wangyao, Danchang district, Supanburi province

摘要

The study of economic and social factors that are affected to the adoption of technology of the farmers, who cultivated non-pesticide vegetables in Wangyao, Danchang district, Supanburi province showed that they faced with low emolument problems from distributing non-pesticide vegetables (94.99%), consumers’ concern for healthy foods (88.89%), high cost of chemical fertilizer in the production (83.88%), health and sickness (55.56%), and amount of labors required in the production (44.44%). An analysis of the use of production function by using the most effective estimation of production function and the real production factor’ farmers indicated the differences between them. The total production quantity of non-pesticide vegetables, which was caused the highest potential production, depended on variables of seed production factor and amount of labor used in cultivation. To increase the total production, the farmers should increase the seed factors and the amount of labor rather than the manure factors. The technical efficiency in production of non-pesticide vegetables by most farmers was high.
