Productivity of stubble catch crops from the cabbage family in a lowland area.

In field trials in 1986-89, winter rape cv. Silesia, Brassica campestris cv. Perko PVH and fodder radish cv. Leveles were grown in rows 0.25 m apart at a sowing rate of 2 million germinable seeds/ha after winter barley cv. Sigra or winter wheat cv. Vala. No catch crops established in 1986 and yields were mostly below 1 t DM/ha in 1987. In 1988, yields after winter barley were 4.18 t DM/ha in Perko PVH, 2.72 t in Leveles and 3.84 t in Silesia; after winter wheat, corresponding yields were 4.51, 3.14 and 4.06 t. In 1989, yields after winter wheat were 2.62-2.81 t. Leveles had the highest proportion of postharvest residue of the catch crops.
