Potato (Solanum tuberosum L.) is an important food and export crop in central highlands of Oromia region. The limiting macro and micronutrients were identified for the production of crops in Boneya districts, but the rates of these nutrients for high potato yield are not yet determined. Therefore, this research was conducted to determine the effect of blended NPSB fertilizer rates on tuber quality related traits and to estimate economically feasible blended NPSB fertilizer rate for potato production at Boneya Kebele, central highlands of Oromia region. The experiment was conducted as factorial combination of seven levels of blended NPSB fertilizer (0, 50, 100, 150, 200, 250, 300 kg ha-1) and three potato varieties (Belete, Gudane, and Jalane) in a Randomized Complete Block Design with three replications. The results revealed that, neither the two main factors (variety and blended NPSB fertilizer) nor their interaction influenced tuber quality related traits. The net benefit obtained from Gudane and Belete varieties was determined by about 72.06 (R2=0.07206) and 81.92% (R2=0.08192), respectively, with the application of NPSB fertilizer and the relationship was linear and significant. The highest MRR (marginal rate of return) of 1802.35% was also obtained from Gudane variety with the application of 50 kg ha-1 NPS fertilizer, however, the highest net benefit of 166175.5 followed by 158899 Birr ha-1 was obtained from Gudane and Belete varieties, respectively, with the application of highest NPSB fertilizer rate of 300 kg ha-1. The combinations of Gudane and Belete varieties with the highest rate of fertilizer also had acceptable MRR of 1434.17 and 760.27%, respectively. Therefore, growing of the two varieties at highest rates of NPSB fertilizer could be recommend for producers because of the high economic returns.
