Analysis of the Profit / Efficiency of Paddy Rice Cultivation with Group Farming by Machinery
Hseih, S. Y. and C. S. Chang
In the first crop season of 1992, rice cultivar Taiken 2 was used in Yuencheng, Yuinlin Prefecture, to evaluate the profit/efficiency of rice cultivation with group farming by machineries. Two groups (replications) with two farm sizes (treatments), i.e. 0.25 ha (treatment A) and 10 ha (treatment B) were used in the experiment. Utilization cost of the machineries consisted of fixed costs such as depreciation and interest of investment, and operating costs such as repairs, fuel, lubricant consumption, and labors. Working cost = utilization costs × working efficiency. Production cost = working cost + costs of the materials for production such as seedling, fertilizer, etc. Results indicated that the working efficiency for treatments A and B were 317 h/ha and 251 h/ha, respectively, or treatment B increased 21% of working efficiency. For working cost, treatments A and B were NT$39,509 dollars/ha and NT$24,312 dollars/ha, respectively, or treatment B reduced 38% of working cost. However, the regular charge was NT$48,739 dollars/ha by the contract farming center under conventional farming system or under individual farm basis instead of farming group. For production cost, treatments A, B, and the conventional method were NT$59,012 dollars/ha, NT$41,967 dollars/ha, and NT$68,945 dollars/ha, respectively, or treatment was 29% and 39%, respectively, lower than treatment A and the conventional method. On the weight basis, the production cost per kilogram for treatments A, B, and the conventional method were NT$7.41 dollars, NT$5.15 dollars, and NT$8.66 dollars, respectively. Treatment B was 30% and 41%, respectively, lower than treatment A and the conventional method. For net profit, treatments A, B, and the conventional method were NT$67,556 dollars, NT$87,391 dollars, and NT$57,623 dollars, respectively. Treatment B was 29% and 52%, respectively, more than treatment A and conventional method.
