Abstract
The main constraints to potato productivity in the study area are low soil fertility and insufficient research-based guidance on the use of blended NPSB fertilizer across various potato varieties. Therefore, the experiment was conducted to evaluate the impact of varying rates of combined fertilizer on the yield components and traits associated with tuber yield in different potato varieties and computes the cost-benefit ratio of NPSB fertilizer rates for potato production in Walmara District. The study involved six (0, 100, 150, 200, 250 and 300 kgha−1) NPSB fertilizer levels combined with three potato varieties, arranged in a factorial design with a randomized complete block setup, and each treatment was replicated three times. The outcomes indicated that, except for stem number, the interaction between NPSB fertilizer and potato varieties had a significant impact on all the tested parameters of potatoes. Belete variety resulted in a higher marketable tuber yield (279.48%) and yields of total tuber (223.23%) in 250 NPSB kg ha−1 fertilization than without NPSB fertilizer. Based on partial budget analysis, the highest 254, 741 net benefits of Birr per ha with a 7684.2% return of marginal rate were observed from the Belete variety with the application of 250 kg ha−1NPSB. Additionally, the Gudane variety with 300 kg ha−1 NPSB fertilization had the highest net benefit with a reasonable marginal rate of return (2780%). Therefore, the tentative recommendation of this research was made toward the Belete variety with 250 kg ha−1 NPSB and as a second option Gudane variety with 300 NPSB ha−1 kg fertilization.
