Abstract
Inappropriate agronomic practices, such as earthing up and inflorescence removal, are responsible for the great discrepancy between the potential and achievable yields of potato in Ethiopia. To assess the effects of the combination on vegetative growth, tuber yield, and yield components of potato, a factorial combination of four earthing up rounds (without, one, two, and three rounds) and three inflorescence removal levels (without removal, bud removal, and flower removal) was used in a randomized complete block design with three replications. The total number of marketable and unmarketable tubers hill-1; the marketable and unmarketable tuber weights hill-1; and the number of small, medium, and large-sized tubers; marketable, unmarketable, and total tuber yields significantly differed in terms of the combined effects of factors. The maximum marketable tuber number hill-1 (10.07), the highest marketable tuber weight (708.67 g hill-1), the highest number of medium-sized tubers (6.95), the large-sized number of tubers (4.48), the marketable tuber yield (31.49 t ha-1), and the total tuber yield (33.08 t ha-1) were all associated with bud removal combined with three rounds of earthing up. Thus, this combination of treatments can be advised for potato production.
