This study analyzed the trend in maize production in Vietnam and estimated a production model while determining factors affecting change in output. Response coefficients were estimated from time-series data covering 1986 to 2011 using the double-logarithm model. Estimated parameters results in model indicated that the maize production also had positive response to the price of maize, the fertilizer per hectare, the maize area, irrigation, the trend variable, and the agricultural extension policy. Recommended policies include: issuing policies to support production; enhancing judicious use of fertilizers; increasing maize area; improving irrigation system; increasing government support for farmers; and improving the extension system with market information. |
