The main purpose of this study is to explain the production and shipment of eggplant and the management of farm
households in the 7th division of the Kojima bay reclaimed land in Okayama prefecture. 10 pioneers began to cultivate
eggplant in a greenhouse in 1969 and the number of farm households, acreage and shipment increased dramatically until
the early 1980s. However, decline or stagnation trend has continued thereafter. Farm workers are often 50 years old or
more, each farmer has cultivated eggplant, rice, two-rowed malting barley in family management by 2 or 3 persons.
Work begins in July. Eggplant seedlings are planted in August, harvest begins in October and heating in November. Pest
control is necessary throughout the year, but pesticide use has decreased in recent years. In order to suppress the occur
-rence of the pests, workers use both the bunker crops like sesame and natural enemies like Amblyseius swirskii . However,
because the prices of agricultural materials and fuel are recently soaring, the farm management of eggplant has become
increasingly severe. We propose to expand the sales network by advertising and a more aggressive acceptance of new
farmers.
