摘要: Cool season food legumes including dry pea, lentil, and chickpea are important components of farming systems in the dry-land regions western United States, most notably Palouse region eastern Washington northern Idaho, provinces Canada, particularly Saskatchewan, Alberta Manitoba. Production has increased dramatically Canada over past five years also production increases have taken place North Dakota South Dakota. California is a major U.S. producer chickpeas. Current stands at about 75,000 tonnes lentils, 150,000 peas 16,000 chickpeas, while 420,000 1,250,000 peas. faba bean, lupin grasspea minimal Canada. Major constraints to include Ascochyta blight lentil chickpea; root rots, wilts, powdery mildew, Mycosphaerella viruses pea. Viruses problematic on chickpea, US when aphid-vector populations increase early growing season. breeding programs concentrated development cultivars that will alleviate meeting market demands. As result success programs, use changed considerably 10 years, trend likely continue. Most legume crop exported as Canadian both feed. trends point The replace summer fallowing States with annual cropping provided considerable additional land area for expanded cool legumes.
