Optimum Rate of Blended Fertilizer and Urea Determination for Potato Production under Irrigation Condition in Holetta Research Center, West Showa, Ethiopia

Abstract

Potato is an important food and cash crop in Ethiopia, especially in the high and mid-altitude areas. Lack of scientific recommendation of fertilizer rate to popular varieties limited crop yield, especially under irrigation potential. The research was conducted in Holetta Agricultural Research Center, under irrigation during 2019-2020 off-season to find and recommend the NPSB blended fertilizer and urea rates for potato using rates of blended NPSB + urea (0, 150
