The response of module leaf and branch of three varieties of Stylosanthes guianensias cv.Reyan 2,Reyan 10 and Reyan 13 to different concentration of N,P and K were studied.The results showed that with increasing of the application rates of nitrogen fertilizer,the number of leaf,first branch,and second branch increased,and reached maximum at the rate of 1.5g/pot N.The module leaf could be facilitated by fertilizer P(P0.05) and its number reached maximum at the rate of 2 g/pot P.The first and second branch number reached maximum while the concentrate of P was over 2 g/pot.The number of module leaf and branch was facilitated by fertilizer K,the leaf and branch number reached maximum at the concentrate 2g/pot K.
