Seasonality of cropping in village homegardens was surveyed at Don Daeng, Northeastern Thailand, from July, 1983 to February, 1984. Chilli was the dominant crop, accounting for 40% of the garden land area in all seasons, though 156 useful plants were recognized there. The planting frequency of papaya, maize, yard long bean, greater yam declined from the rainy season to dry season. Cultivation of garlic, shallot and <I>Brassica</I> spp. predominated in the dry season. Crop yield was the highest in November and the lowest in August. Cultivation activity changed appreciably each month. This seasonality pattern was presumably related to the ecological traits of the crops, climatic conditions and rice cropping calendar. Removal of competition with rice cultivation may promote crop production in garden land and bring stability to rain-fed agriculture.
