This report clarifies the reason for the conversion from Indica rice to Japonica rice production of farmers in the Mekong River delta, Vietnam, by comparing the management features by Japonica rice contract cultivation farmers with those of Indica rice in the My Hoa District, Long Xuyen City. The results are as follows: First, in Japonica rice production, more intensive labor is demanded but relatively high sale prices and higher farm incomes are achieved by thorough post-harvest quality control. Therefore, the ratio of full-time farm household of Japonica rice increases over that for Indica rice. However, it is necessary to consider future environmental problems, as both fertilizer amount and planting frequency increase. Second, based on its high profitability, the number of farmers who intend to expand Japonica rice production through the use of leased land and employed labor have increased. The rent is formed within the surplus of Japonica rice. Therefore, conditions for conversion from Indica rice to Japonica rice production and development of management by leased land are formed.
