Common bean is among the vital legumes cultivated for nutrition, foreign currency earnings, and income generation. Common bean production is constrained mainly by nutrient deficiencies. A field experiment was conducted at Sodo Zuria Woreda to assess the effects of blended N-P-S-B fertilizer rates and Rhizobium strain on yield and yield traits of common bean and income of farmers. Treatments were five different rates of blended NPSB fertilizer (0, 50, 100, 150, and 200 kg ha) and two types of Rhizobium strains (HB-A15 and HB-429 ()) and control (without inoculation). Randomized complete block design in factorial arrangement with three replications were used. Results showed that interaction of blended NPSB rate and Rhizobium strain type had significant effect on the number of effective nodule, grain yield, and above ground dry biomass. Application of 150 kg NPSB ha along with inoculation of resulted in the highest grain yield (3017.7 tons ha). Similarly, economic analysis indicated that the highest net return of 38298.545 ETB ha was obtained from combined application of 150 kg NPSB ha along with . Thus, it could be concluded that using strain with 150 kg NPSB ha was found to be appropriate for common bean production in the area.
菜豆是为获取营养、赚取外汇和增加收入而种植的重要豆类之一。菜豆生产主要受到养分缺乏的限制。在索多祖里亚县进行了一项田间试验，以评估氮磷硫硼混合肥料施用量和根瘤菌菌株对菜豆产量及产量性状以及农民收入的影响。处理包括五种不同施用量的氮磷硫硼混合肥料（0、50、100、150和200千克/公顷）、两种根瘤菌菌株（HB - A15和HB - 429（））以及对照（未接种）。采用随机完全区组设计，析因排列，重复三次。结果表明，氮磷硫硼混合肥料施用量与根瘤菌菌株类型的交互作用对有效根瘤数、籽粒产量和地上部干生物量有显著影响。每公顷施用150千克氮磷硫硼混合肥料并接种 ，籽粒产量最高（3017.7吨/公顷）。同样，经济分析表明，每公顷施用150千克氮磷硫硼混合肥料并接种 ，净收益最高，为38298.545埃塞俄比亚比尔。因此，可以得出结论，在该地区，每公顷施用150千克氮磷硫硼混合肥料并使用 菌株适合菜豆生产。
