| Abstract | Leaf spot and rust are one of the most important diseases Faba beans (Vicia faba L.) in Jordan. Present study was conducted to evaluate the effectiveness of two irrigation types (drip and sprinkler) and host resistance in three field bean genotypes on development of leaf spot and rust under Jordan valley conditions. The results provide evidence for a wide spread of diseases being the main cause of yield losses in faba beans. Chocolate spot was relatively important because of the rapid leaf loss and potential to cause yield losses, being most damaging during flowering stage. However, rust was an occasional problem in Jordan valley and occurred late in the season during podding stage. Cyprus irrigated with drip irrigation showed higher disease severity compared with other two cultivars and it showed 50% reduction in disease severity with sprinkler irrigation Minor Beck cultivar showed the least percentage of disease severity during the first two evaluations. Sprinkler irrigation markedly increased the disease severity of broad bean rust in all cultivars. Disease severity was increased from the first evaluation to the second about 165%, 96% and 140% for drip irrigated cultivars minor beck, equina and cyprus respectively, while it was increased by 140%, 90% and 75% for the same cultivars irrigated with sprinkler irrigation. In most disease severity ratings, minor beck cv. irrigated with both irrigation systems showed the highest disease severity compared with other cultivars. |
