The effect of three levels of shading (0; 30 and 50%) on the development and tuberous root yield of radish (Raphanus sativus L.) cv. "Vermelho Redondo" was studied under field conditions, at the São Manuel County, State of São Paulo, Brazil. The plants were evaluated at 7, 14, 21 and 28 days after the emergency. The 50% level of shading increased the life cycle and foliar area, reduced the leave chlorophryll content and the tuberous root yield. The 30% level of shading did not reduce the size and weight of the roots.
