Cambodia is still emerging from an extent period when the agricultural
production and support system was severely degraded. Agriculture is the
fundamental sector of the Cambodian economy and is a top priority for development
programs (May, 2001). Over the period 1993-2001, agriculture was the major sector
of the economy, the contribution of GDP is an average of 46.4 percent of total GDP in
Cambodia (MAFF, 2003). However, current public investment in agricultural research
constitutes a relatively small portion of the total Cambodian government budget
because of resource constraints (MOP, 1999). The research programs have been
conducted based on the priority needs of the country arid the availability of a budget
provided by the government and international assistance.
