ประสิทธิภาพทางเทคนิคการผลิตถั่วเหลืองในจังหวัดเชียงใหม่

Abstract

This study aimed to study the aspect of production management, the usage of inputs, problems and obstacles in soybean produce for agriculturists in Chiang Mai. The study also includes technical efficiency and finding factors that affect it. The data was collected from the interview of 100 agriculturists in 4 districts in Chiang Mai, then analyzed using Stochastic Production Frontier method. By using Cobb-Douglas with Copula function. The result was found that the main decision makers had an average soybean growing experience of 16. The majority of agriculturists use Chiang Mai 60 seeds for the plantation. The average soybean planting area is 6.33 rai. 56 percent of the agriculturists rent the land while 44 percent have their own land. The soybean planting area was in the irrigated area (58%). It was found that the average seed consumption was 16.68 kg/rai, the average labor used in soybean cultivation was 17.53 people/rai, and the average fertilizer consumption was 17.53 people/rai. 24.51 kg/rai, the average pesticide use was 0.26 liters/rai. The average product of soybean plantation is 310.13 kg. per rai, which equals to the income from the plantation of 5,876.96 baht per rai. The average cost is 7,290 baht per rai. Therefore, the net income over total cost equal -1,413.04 baht per rai. According to the analysis of technical efficiency of soybean production it was found that the level of technical efficiency of soybean production has the average at 0.77 which indicates that soybean production of the agriculturists is in medium level. The factors that can help increase the produce are, the number of labors in the process, the expense for fertilizers, and the amount of soybean seeds that are used in the production. The factors that affect lack of soybean technical efficiency are land ownership, experience in plantation, and the size of the plantation area. From the study, the agriculturists can use the result to plan the guidelines for increasing soybean technical efficiency and manage the problem in soybean production for the produce to have more quality. Moreover, agents or organizations that are related to this field can use the result to plan their operation plan in the next step.
