Abstract:The impact of roadway lighting on soybean plant growth and development, was measured in situ at three locations in the state of Illinois. These locations were situated in close proximity of each other for the purpose of evaluating whether there was a difference in the soy response to HPS roadway lighting, versus soy lit by a specific model of 4,000K LED roadway lighting. The plant data collection included the reproductive-stage, the plant moisture content, and the dried seed weight after harvest. The impact of the type of roadway lighting on the reproduction stage and normalized yield was within the modeling confidence limits at a level of 90%. Modifications are recommended to the specification for roadway lighting trespass. This will minimize the impact on soybean plants based on the two roadway luminaire designs included in this study.
