The objective of this study is to evaluate the economic impact of the adoption of technology on rice cultivation in the Senegal River Valley and the Anambé Basin
The study shows that the average cost of production of the various types of exploitation of the valley is estimated at 101 FCFA/kg, of which 10% of fertilizer cost with a margin of 29 FCFA/ kg
Summary
Agricultural Research & Technology: Open Access JournalIn the Senegal River Valley and the Anambé Basin where yields are high (averaging 4.5 to 7t/ha), the use of fertilizers is crucial. The recovery rate of nitrogen hardly exceeds 30% for the rice plant [1] This form of application results in significant losses of nitrogen in the runoff water, groundwater and air, reducing the amount available to the plant while polluting the environment (Figure 1). Compared to this practice, the deep placement of super granulated urea (PPU) technology is a technique of burying by hand or applicator a super granule of urea fertilizer or “briquette” be tween 4 rice bunches at a depth 7-10cm [2]. This technology, tested and validated in a farm environment, aims, among other things, to improve rice yields and reduce production costs
