Abstract

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