Stages and determinants of fertilizer use in semiarid African agriculture: the Niger experience

摘要: Fertilization is a stepwise decision in Niger. Survey data from representative sample of 100 households were utilized with individual and joint estimation to evaluate the determinants fertilizer use at its three different stages: manure alone two types inorganic application. The price relative millet was always highly significant determinant adoption. Farmers' experience seeing results fertilization field principal factor influencing micro-fertilization. Other studies semiarid regions have emphasized risk, liquidity, or responsiveness under harsh conditions but shift micro doses statistically associated here demonstration trials ratios (fertilizer/millet). A variable reflecting recovery approximately 6 months after harvest most important raise further side dressing. Policy implications focused on importance improvements economic (millet–fertilizer ratios).
