Growth and yield of field-grown soybean in response to enhanced exposure to ultraviolet-B radiation

The objective of this study was to examine the influence of a 32% enhancement of UV-B irradiance at Gainesville, FL on the growth and yield under field conditions of six soybean cultivars. No influence of either UV-A or UV-B radiation was detected on any growth parameter studied. Leaf area development, internode length, phyllochron index, flowering date, podding date, crop growth rate, and final seed yield were unaffected by enhanced exposure to ultraviolet radiation
