Abstract
THE growing of salad crops has become a highly specialised business in several parts of England and there seems no reason why the acreage devoted to this branch of horticulture should not be profitably extended. As an aid to growers, whether on a large or small scale, the Ministry of Agriculture has issued an illustrated bulletin (No. 55, H.M. Stationery Office, Is. 6d. net), from which it is evident that with good management it is possible to have supplies for the market throughout the whole year. Lettuce is quite the most important crop that is included under the term salad, and the best methods for its cultivation in the field, in heated and unheated glasshouses or in frames, are described in detail. Some account is given of the varying methods adopted in different districts and the varieties found to be most satisfactory in each locality, while cultural methods in use in other countries such as America and France are also included. Watercress is another important crop grown for salad purposes. Although little difficulty is experienced in its cultivation, it is essential that the water in which it is grown should be of the highest quality as the industry has suffered considerable harm from cress grown in contaminated streams. Attention to local conditions and markets, and the choice of a suitable variety to meet these requirements, are also needed if the cress-growing is to prove a thoroughly profitable undertaking.
