抄録

To investigate the conditions necessary for the year-round supply of 'Nitakikoma' cooking tomatoes, we investigated the relationships between air temperature and the dates of planting, harvest start, and harvest end under different cropping conditions. The days from planting to harvest start and harvest end were shorter as temperature rise, those relationship were shown by the regression formulas. To reduce fuel consumption in winter but maintain stable fruit production, we grew tomatoes in an unheated greenhouse and in an inflated plastic house. The fuel consumption of the inflated house was about 40% less than that of a usual plastic house, but there were no difference of yields between them. Control of harvest period may be made possible by intentional changes of air temperature in a greenhouse during culture.
