Integrated management approaches reduced yield loss, and increased productivity in faba bean, due to gall disease in northwestern Ethiopia

ABSTRACT

A field study was conducted to determine the effects of gall disease on yield and yield components of faba bean at Farta, Ethiopia, in 2019 and 2020. Bayleton spray and/or seed dressing, moderately resistant varieties, and intercropping as treatments were arranged in a split-split plot design with three replications. Results revealed significant (P < 0.01) differences among treatments in disease severity, yield and yield components of faba bean. Highly significant and negative correlations between agronomic and disease parameters were established. Gall disease pressure caused yield losses of 60, 67.61 and 68.61% on Bulga 70-wheat, Bulga 70-mustard intercropping and sole Bulga 70 in untreated plots, respectively. Integration of varieties Degaga and Tumsa with fungicide treatments reduced yield losses and gall disease epidemics, and also increased efficiency of intercropping by 20% over respective sole cropping in both years;and thus, such treatments could be recommended in the study areas and other related agro-ecologies.
