摘要

本研究的目的是通过确定不丹南部的成本和回报来评估当前种植方式下水稻种植的盈利能力。采用多阶段随机抽样方法,选取300名农户作为样本。用于数据收集的主要工具是预先测试的半结构化问卷。预算技术和描述性统计用于分析数据。研究表明,投资52434亩(约738.5美元)的水稻种植总收益为52500亩(约740美元)。因此,毛利率为1066元(≈15美元),相当于总成本的2.1%。分析表明,该品种的效益成本比为1.021,精米价格和产量分别为69(≈0.97美元)Kg -1和735 Kg。水稻种植是劳动密集型的,它占总成本的77%,而其他成本只占13%。效益成本比的敏感性分析表明,水稻生产对生产率和劳动力需求的变化比补贴更敏感。尽管生产力很低,但不丹南部的土壤肥力和作物管理都很差。因此,该研究建议进行技术干预,如农业机械化和探索节省劳动力的技术,采用高产改良品种,土壤和作物管理。另一方面,补贴、补偿和激励等相关的政策干预对于水稻种植的盈利也很重要。

RICE PRODUCTION ECONOMICS OF SUB-TROPICAL AGROECOLOGY IN SOUTHERN BHUTAN
The objectives of this study were to assess the profitability of rice cultivation under the current cultivation practices through the determination of cost and return in Southern Bhutan. Using the multi-stage random sampling method, 300 farmers were included in the sample. The main tool used for data collection was a pre-tested semi-structured questionnaire. Budgeting techniques and descriptive statistics were used for analyzing the data. The study reveals that gross return was Nu. 52500 (≈USD 740) acre -1 of rice cultivation from the investment of Nu. 52434 (≈USD 738.5). Thus, the gross margin was Nu. 1066 (≈USD 15) which is equivalent to 2.1% of the total overall cost. The analysis shows that a benefit-cost ratio of 1.021 with break-even price and yield at Nu. 69 (≈USD 0.97) Kg -1 and 735 Kg milled rice respectively. Rice farming was found labour intensive and it accounts for 77% of the total cost whereas that of other costs constitutes only 13%. Sensitivity analysis on the benefit-cost ratio shows that rice production is more sensitive to change in productivity and labor requirements than subsidy. Despite low productivity, soil fertility and crop management were found poor in southern Bhutan. Thus, the study recommends technical intervention such as farm mechanization and exploration of labor-saving technologies, adoption of high-yielding improved varieties, soil, and crop management. On the flip side, pertinent policy interventions like subsidies, compensation, and incentives are also important to make rice farming profitable.
