Turnips are grown principally in the central provinces as an alternative crop to wheat.
The chief crops grown for early supplies, or " primeurs " as they are called, are special varieties of cos and cabbage lettuces, short carrots, radishes, turnips, cauliflowers, endives, spinach, onions, corn salad and celery.
Sow carrots, turnips, early celery, also aubergines or egg-plants, capsicums, tomatoes and successional crops of kidney-beans; cauliflower and Brussels sprouts, in gentle heat, to be afterwards planted out.
For turnips bone manure is invaluable.
Of the flora of Tibet Rockhill writes: " In the ` hot lands ' (Tsa-rong) in southern and south-eastern Tibet, extending even to Batang, peaches, apricots, apples, plums, grapes, water-melons, &c., and even pomegranates, are raised; most of Tibet only produces a few varieties of vegetables, such as potatoes, turnips, beans, cabbages, onions, &c. The principal cereals raised are barley and buckwheat, wheat in small quantities, and a little oats.
