Low fertilizer use in Sub-Saharan Africa has led to poor crop yields, especially in maize. By studying data from 1990-2010, researchers found that increasing fertilizer application positively impacts maize output. Factors like land, labor, rainfall, and specific nutrients in fertilizers also play a role in boosting maize production. To improve yields, countries should promote more fertilizer use through strategies like subsidies, reducing import fees, and educating farmers on the benefits of proper fertilizer application. Additionally, implementing supplementary irrigation methods can help mitigate the negative effects of unpredictable rainfall.
