摘要
背景:由于淡水的稀缺性,水生产力被认为是农业生产力的一个重要指标。以同等或更少的水量换取更高的产量已成为全球关注的问题。目的:本研究以孟加拉国拉杰沙希两个洪泛区的水稻种植为例,测量了洪泛区土地上的水分生产力。材料与方法:本研究采用直接观察法收集2006-07年度30个样本的生产和市场价格数据。结果:水稻产量的总水分生产力分别为0.47 kg m-3和0.43 kg m-3。在货币价值上,按总收益、考虑现金成本的净收益和考虑全部成本的净收益计算,每立方米灌溉水的水生产率分别为5.65、3.42和2.64泰克。在Chandpur地区,这些值分别为5.19 m-3、2.87 m-3和2.14 m-3。平均灌溉用水量估计为10730.05 m-3和11236 m-3,平均产量分别为4992.95 kg和4783.20 kg。统计结果表明,在保持灌溉水量不变的情况下,水稻产量每增加1%,水分生产力分别提高0.916%和0.972%。群落型养鱼管理的干预使梅尔河的水分生产力比昌德普尔河高4.65%。结论:本研究结果对合理利用河漫滩土地治理和提高生产具有指导意义
Water Productivity for Boro Rice Production: Study on Floodplain Beels in Rajshahi, Bangladesh
Context: Water productivity is considered as an important indicator of Agriculture productivity because of the scarcity of freshwater. More yield or output against same or less amount of water has become the global interest. Objectives: This study measures the productivity of water on the floodplain land in terms of Boro rice cultivation for two floodplain beels in Rajshahi Bangladesh. Materials & Methods: For this study, the production and market price data were collected by direct observation based on 30 samples in the year 2006-07. Results: This study found gross water productivity of rice yield as 0.47 kg m-3 in beel Mail and 0.43 kg m-3 in beel Chandpur. In monetary value, water productivity per cubic meter irrigation water were TK 5.65, TK 3.42 and TK 2.64 based on gross return, net return considering cash costs and net return considering full costs in beel Mail. In beel Chandpur these values were TK 5.19 m-3, TK 2.87 m-3 and TK 2.14 m-3, respectively. The usage of average irrigated water in the boro rice farms were estimated 10730.05 m-3 and 11236 m-3 with an average production of yield 4992.95 kg and 4783.20 kg in beel Mail and beel Chandpur. Statistical result shows that keeping irrigation water constant, a 1% increase of boro rice yield will increase water productivity at 0.916% in beel Mail and 0.972% in beel Chandpur. The water productivity in beel Mail was 4.65% higher than beel Chandpur due to the intervention of community based fish culture management. Conclusion: The findings of this study will help to govern and improve production by proper utilizing floodplain lands
