Abstract
An experiment was conducted at Angacha Research Station in Kembata Tembaro Zone of Southern
Ethiopia to evaluate the response of potato (Solanum tuberosum L.
) to potassium fertilizer.
Increasing
rates of K (0, 40, 80, 120, 160, 200, 240, 280, and 320 kg ha-1
as KCl) in RCBD with four replications
were used in the experiment.
Recommended rates of N and P, 111 and 39.
3 kg ha-1
, respectively were
applied to all treatments.
Urea (46-0-0) and DAP (18-46-0) were used as sources of N and P.
N was
applied in split at planting and after tuber initiation (as side dressing).
The composite soil sample
contains moderate organic carbon (1.
6%), whereas th
