KNOL-KOHL, or KOHL-RUBI (Bra'ssica 

 cau'lo-ra'pa), the Turnip-stemmed Cab- 

 bage. It is sometimes called, also, the 

 Cape Cabbage. The stem is thick, rises 

 about eight inches out of the ground, is 

 swollen into a globular form, very like 

 a large Swedish turnip growing above 

 ground, and is crowned with leaves, 

 slightly scolloped on the edges, undu- 

 lated, and milky-green, like those of the 

 turnip we have mentioned. There are 

 several varieties of it; but the green- 

 stemmed and the purple- stemmed (espe- 

 cially the latter) are to be preferred. 



It is sweeter, more nutritious, and more 

 solid than either the Cabbage or White 

 Turnip; will produce a greater weight 

 per acre than the turnip, and prefers a 

 heavier soil than that root ; is hardier, and 

 keeps better than any other bulb ; and 

 imparts very little of that flavour, either 

 to milk or butter, known as turnipy. So 

 much relished is it both by cows and 

 sheep, that they will leave either turnips 

 or cabbages to partake of it. Hares and 

 rabbits are so fond of it, that where they 

 abound, Knol-kohl can scarcely be grown. 

 It is excellent when boiled for table. 

 Sow in the first week of March, and 

 plant out in June in rows four feet apart, 

 if the soil is fertile, but only three feet 

 if the soil is less productive, and three 

 feet from plant to plant in the rows. 

 The plants must have the chief part 

 of their stems left uncovered by the 

 soil. Two pounds of seed produce enough 

 plants for an acre. It is an excellent 

 crop for cleaning the soil, as the width 

 between the plants and rows enables the 

 'hoe to be efficiently used, and during a 

 lengthened period. When blanks occur, 

 these may be filled up from the seed-bed 

 with fresh plants. The produce is from 

 eighteen to twenty tons, and upwards, 

 per acre. The bulbs may be kept sound 

 and nutritious until very late in the 

 spring, even much later than the Swedish 

 turnip.
