Abstract

Coffee (Coffea arabica L.) is known to be one of the most important beverages in the world and is a very important source of foreign exchange for many countries. Old coffee rejuvenation or stumping is one of the most and commonly used by coffee producing countries for productivity enhancements methods especially for those poor productive due to old age and as well as genetic conservation practice. The most and large coverage of old coffee plantation is the most production constraints in almost all coffee growing areas of Ethiopia. A field experiment was conducted at Awada Agriculture Research Sub-center experimental site between 2013 and 2020 with improved south Ethiopian coffee selections to determine appropriate Vertical number and topping practices for enhanced yield and yield component. Four vertical or bearing head number and topping practices (Topped single stem, Topped multiple stems, Untopped multiple stems, and Free Growth) were used as treatments and laid out in a randomized complete block design (RCBD) with three replications, to identify the effects of old coffee tree stumping and number of verticals with topping practice. Analysis of variance revealed that; clean coffee yields and growth parameters were significantly influenced by the different numbers of verticals and also topping practice. The analysis of variance also revealed highly significant yield variations among topping practice and the number of verticals. Free growth and topped multiple stems revealed the highest and statically similar yield performance throughout the cropping season as compared to the other treatments. Therefore, these finding indicates that topping practice and the number of verticals significantly promoted the yield responses of Arabica coffee cultivars under field condition. Therefore, topping multiple stems and free growth were selected as a promising practice to enhance coffee yield and yield components.
