| Abstract | This study aimed to look for cause of unsuccessful Good Agricultural practice (GAP) implementation in tangerine orchard and propose the policy to support GAP. The study area was Mae Ai district, Chiang Mai province. The samples of GAP orchards were selected 30 farmers in 3 sub districts by random sample. As the total sample of traditional orchard were selected thirty farmers in each sub district based on proportion in each sub district. Almost tangerine orchards were small and medium. Average age of growers was 50 years old. Most tangerine growers‟ education had only primary level. Also, average cultivation experience was 9 years. Comparative economic analysis of traditional and GAP tangerine orchard, large farm on traditional implementation was good investment project. Among of 4 projects, the project had best profitable was large farm of GAP cultivation system because there is positive NPV, highest BCR and IRR. NPV‟s farm was positive. As for BCR, IRR and PB were 1.338, 17.16 % and 5 Years 9 Months 28 Days. When analyzing the sensitivity of the total decreasing revenue 20% and production delay in fifth year were affected small farm in traditional system. The net present values (NPV) were negative. Small traditional farm had BCR less than 1. Thus, if traditional producer in small scale were affected by factors such as potential increasing cost or the revenue decline. They may lead to a loss. As health issue, the majority of suffering from toxicity symptoms of growers occurs from misused and mishandled pesticides. The average of sick day was 1 day. The highest cost was preventive cost (protective equipment; boots, wide hat). The average of health cost of traditional and GAP in 2011 was 174.37 Baht/rai and 185.18 Baht/rai respectively. When combine between health cost and cost of production, the total cost of traditional farm and GAP farm were 37,687.8Baht/rai and 41,978.1Baht/rai respectively. |
