Great relevante on the studies regarding the degree of tolerante of the legumes to shading in the LeyCropping Systems. The behaviour of the legumes Aradas pintoi (Arachis), Craty/ia argentea (Cratil ia), Maeroptilitunatropmpureum (Siratro) and Ptteraria phaseoloides (Kudzu Tropical) was evaluated under 3 leveis of shading 25%, 50%and 75%. The shading effect was obtained by using nylon screens for covering cubic frames seitled over the legume plots.The experiment was carried out at Em bruna Agrobiologia experimental arca at Seropédica, RJ. Shading increased the lengt hof the stems of Kudzu and Siratro in the first cut while leaf dry matter only increased for Kudzu in the shade levei of 25%.In the 2nd cut, Kudzu and Siratro presented the higher root dry matter production ai 25% shading, Arachis at 0% andCratilia presented no response to shading. In the cut dry matter of stems of Kudzu Tropical, Siratro and Cratilia were notaffected by shading, but Arachis presented a reduction of stern dry matter of 94% when shading increased from 50 to 75%.
