1. Effects of Adopting Fertilizer Management Practices on Yield in Maize-Based Systems of Embu County: an Instrumental Variable Regression Approach

Fertilizers play an important role in maize production and global food security, contributing significantly to yield increases. However, continuous rise in fertilizer prices has resulted in inflated costs, leading to unaffordability and suboptimal utilization. Inefficient use by farmers has hindered yield potential and increased environmental risks. Additionally, farmers' limited knowledge and awareness of optimal nutrient requirements, timing, application rates, and  placement techniques... M. Gitau, R.A. Nyikal, , O. Kitonyo
