SUMMARY Kale and swedes were grown together either in alternate drill rows, or as alternate singled plants within the row. In 2 years' experiments neither of these spatial arrangements gave an increase in total dry‐matter yield over that of either kale or swedes in pure stand. The yield of both kale and swedes when grown together was generally adversely affected by the presence of the other species. It is tentatively concluded that there was competition for light, for nitrogen and possibly for water.
