Abstract—This study was done to determine what wavelengths of light affects the vegetative growth of
Brassica rapa grown in pots in urban area. Quasi-experimental method was used in this study.
Brassica rapa seedlings were exposed to different colors of light (white blue green, yellow and red) eight hours in the evening for two weeks of vegetative growth. The leaf size, number and color of leaves were monitored. Data was analyzed using ANOVA-single factorial. Result of the study revealed that plants exposed to white color gave the highest length, width and average number of leaves after fourteen days, followed by plants in treatment 3 (green light), treatment 2 (blue light), treatment 4 (yellow light), the least in treatment 5 (red light). Base on the result of the study white colored fluorescent bulb is recommended as supplementary lighting to
Brassica rapa grown in pots in urban areas.
Index Terms—Brassica rapa, growth response, wavelength of light
