Economic Evaluation of Factors Influencing Maize Yield: in North-rift Region of Kenya

The study shows that the inputs of fertilizer, labor and seed have a significant influence on maize yield, with yield being more responsive on seed. Labor is applied by farmers at its economical optimal level whereas both seed and fertilizer are being applied at sub-economic optimal. The study's findings further show that when fertilizer, labor and seed are applied at their economically optimal level, forecasted maize yield ranges from 1694 kilograms per acre for the transcendental to 1920 kilograms per acre for the Cobb-Douglas functions. This is in comparison to the current average yield of 1078.8 kilograms per acre. Furthermore, the study shows both training and agricultural credit has an insignificant influence on maize yield.
