摘要

Comparison of the effects of supplemental lighting with fluorescent lamps inside the plant canopy on the yield of tomato plants (Solanum lycopersicum L.) was attempted under the following lighting schedules; (A) 2 hours around sunrise, (B) 2 hours before noon, (C) 9 or 10 hours during the daytime, (D) 2 hours before noon but only when sunlight was below 200 micro mol m-2 s-1 and (E) 9 or 10 hours during the daytime but only when sunlight was below 200 micro mol m-2 s-1. Supplemental lighting increased yield in all schedules. Schedule C showed the largest increase, followed by B, and A. The limited lighting treatments (schedules D and E) were less effective than the corresponding unlimited treatments (schedules B and C). Schedule C was best in terms of increased yield in this experiment but was not efficient in terms of lighting cost. Schedule B was the most cost-effective option in this experiment but needed more decreasing of lighting costs for practical use.
