Urban land which has limited space means
that kenikir vegetables grown in
urban areas are very limited. One way
to overcome this condition is by
growing microgreen vegetables indoors with LED lighting. LED (Light Emitting
Diode) lights are used to meet the light needs of plants, are safe to use in
plant culture, do not contain mercury, and do not produce high temperatures
that can harm microgreen plants. This research aims to determine the effect of
long exposure to LED lights on the growth of kenikir microgreen on various
planting media. Research was conducted at the Plant Physiology &
Biotechnology Laboratory and Soil Physics Laboratory, Faculty of Agriculture,
Sebelas Maret University, Surakarta from February to May 2023
This research uses a nested research
design with 2 factors and 3 replications, the first factor is the length of
illumination of the LED lights (4 levels), namely 8, 12, 16 and 24 hours, the
second factor is the planting media (3
levels) consisting of flannel cloth, rockwool, and cocopeat. The variables
observed included plant height, cotyledon leaf area index, plant fresh weight,
plant dry weight, number of cotyledon leaves and chlorophyll content.
The results of the research showed that different planting media did not show differences in results between one and another in the growth of kenikir microgreens, cocopeat planting media had better results compared to other planting media for the growth of kenikir plants.
