Abstract

Driving factors aggravating coffee leaf rust caused by biotrophic fungus Hemileiavastatrix Be & Br. was critically assessed and examined in 406 sample coffee farms from 27 districts, nine zones across major coffee growing two regions (Oromia and SNNPR) of Ethiopia. All associated environmental and soil factors were noted carefully from each plot. Univariate analysis as of linear mixed model was fitted separately to each variables for testing the effect of categorical factors as fixed effects tested individually in the model. A linear regression model was fitted to data on the relationship between dependent and independent variables. Multiple correspondence analysis was used to identify individuals with similar profile and the associations between categorical variables. Based on the study, CLR is widely distributed all over coffee growing areas of the country with varying intensities. There was a highly significant (p < 0.001) and negative correlation between altitude, management practice and shade level with CLR intensity. Moreover, there is highly significant (p < 0.001) and positive correlation between coffee production systems and coffee cultivars with disease intensity. Based on the study number of factors affect the disease epidemics, such as climate change effect of high temperature, lack of known durable resistant coffee varieties, lack of disease management practice and lack of recommended fungicide application. This empirical evidence shows that CLR was an upsurge and interacting with number of factores and will be remains a major challenge to Arabica coffee production in Ethiopia.
