This review includes information relating to the impacts of different irrigation application methods on yield and water use in salad (lettuce) production, including pressurised overhead irrigation (e.g. sprinklers, centre pivot), localised micro-irrigation (drip or trickle) and gravity fed surface (furrow) irrigation.

This factsheet provides results of nitrogen response experiments focusing on baby leaf lettuce (Lactuca sativa).

Brassica crops can be infested by up to 49 different species of pest insect. Fortunately, most of these occur infrequently on horticultural Brassicas. They include flies, beetles, caterpillars, aphids and whiteflies. Pests can reduce yield and crop quality through direct feeding damage, transmission of plant viruses and contamination

Turnip yellows virus (TuYV), is spread by aphids, mostly the peach–potato aphid (Myzus persicae). The virus can dramatically reduce yields, especially when plants are infected early in the growing season. It is well established in Europe, and is especially common in areas of intensive brassica production in UK.
