| This paper used the Uganda National Household Survey (UNHS) dataset of 2005/06 to examine the productivity of improved inputs used by smallholder maize farmers in Uganda. Yield and gross profit functions were estimated with the stochastic frontier model. Results revealed a significant effect improved inputs use on yield but not gross profit. Farmers who used commercial improved seed with fertiliser obtained superior yield but lower gross profit compared to farmers who planted recycled seed (of improved variety) without fertiliser. Furthermore, if the opportunity cost of own land and labour inputs in maize production were imputed, overall, farmers made economic losses. Based on the prevailing farmers’ production technology and market conditions, maize... |
