Abstract |
|
内容記述 |
A promising agricultural technology to alleviate food insecurity and poverty among resource constrained farmers in sub-Saharan Africa involves the strategic application of fertilizers derived from the region’s abundant phosphorus resources. While the agronomic performance of this technology has been experimentally assessed with a promising outcome, its economic performance and superiority over low-cost, unfertilized production in actual farmers’ fields have not been thoroughly investigated. Through participatory on-farm trials, this study illustrated the relative profitability of alternative NPK fertilization methods utilizing Burkina Faso phosphate rock for sorghum and cowpea production across various fertilizer price scenarios. Additionally, it evaluates the economic feasibility of expanding fertilized production using these alternative fertilization techniques among farmers. This analysis uses a whole-farm economic model based on linear programming, developed from comprehensive data across entire plots—including those using conventional and alternative fertilization methods—and designed to determine optimal combinations and adoption scales for these techniques. On-farm trial results indicate that alternative fertilization modestly improves yields for both sorghum and cowpea, with compound fertilizers containing partially acidulated phosphate rock and organic manure showing relatively high cost-effectiveness. Whole-farm economic analyses demonstrate that the optimal fertilized area using alternative fertilization techniques is similar to the current fertilized area when assuming approximately a 50% markup on the alternative fertilizer’s production cost. This finding suggests that farmers are unlikely to gain economically from expanding fertilized production using alternative fertilizers if their prices exceed a 50% increase over base production costs. Therefore, reducing fertilizer manufacturing and transaction costs is essential to keep prices well below this threshold and/or to enhance yield effects through advancements in fertilization techniques and complementary agronomic practices. |
