The yield and composition of lucerne, grass and clover under different systems of management. 6. Residual fertility
J. Brit. Grassl. Soc 19(3): 358-61
Differences resulting from previous cropping were shown in the yields of the first test crop of rape and also in the following test crop of oats. Rape yields were highly correlated with the yield of the legume crop harvested earlier in the season, the highest residual effect being observed after lucerne, followed by lucerne/ grass, red clover/grass and grass alone, in descending order. The application of N to the legume and grass swards reduced the yield of oats, the second test crop.
