The objective of the study was to evaluate the productivity of five fodder crops (white mustard, radish, winter rape, sunflower and tansy phacelia) cultivated as a stubble intercrop after winter wheat depending on the fertilisation method: cattle slurry, straw-and-mineral fertilisation and mineral fertilisation only. The field experiment was conducted over 1996-1998, at the Mochełek Experimental Station in the vicinity of Bydgoszcz, on a very good rye complex soil. Over three research years high yields of fresh and dry matter were noted. However a great variation among species in their productivity was observed and ranged from 4.53 t D.M.·ha^-1; 4.36t D.M.·ha^-1 to 4.32 t D.M.·ha^-1 for radish, tansy phacelia and white mustard respectively, to 2.74t D.M.·ha^-1 for sunflower. The method of straw-mineral fertilisation resulted in a lower yielding of aboveground parts of radish, rape and sunflower. Over low-rainfall years after sowing a lower seed emergence was recorded for objects fertilised with straw than for the other objects.
