Effect of ploughing-in stubble and catch crops on the fertility of light soils

, : Effect of ploughing-in stubble and catch crops on the fertility of light soils. Nowe Rolnictwo 23(16): 4-5

Yields of early potatoes were 9.3 t/ha without stubble cultivation, 11.5 t/ha when the preceding rye stubble was ploughed-in immediately or 2 or 4 weeks after harvest, 9.4 t/ha when a green manure catch crop of serradella which had been intersown with the rye in May was ploughed-in and 12.0 t/ha when a catch crop of winter rape (Brassica napus var. oleifera subvar. biennis), sown immediately after the rye harvest, was ploughed in.
