The study looked at what factors drive crop productivity in Nigeria. They used data from different states between 1995 and 2006. They found that increasing crop production in Nigeria is mainly due to using more land. Having more female workers also helps increase productivity. Using fertilizer can improve crop yield, but it needs to be used correctly. The study suggests using new technologies to increase crop production without needing more land. It also recommends teaching farmers how to use fertilizer properly and encouraging more female farmers to participate in crop production.
