In Ethiopia, bread wheat (Triticum aestivum L.) is an important source of food and income for smallholder farmers. However, its productivity is very low, which is attributed to poor agronomic and soil fertility management practices. Therefore, a field experiment was conducted in Damot Gale district during 2021 main cropping season in order to identify the effect of blended (NPSB) fertilizer rates on growth, yield and yield components of bread wheat genotypes as well as to determine the optimum and economically feasible fertilizer rate for bread wheat production. The experiment consisted of four levels of NPSB (0, 75, 150, 225 kg ha-1) and three bread wheat genotypes G-226930, G-238133 and G-238871 and with one standard check (Alidoro) variety combined factorial and laid out in randomized complete block design with three replications and analyzed by using. Data on crop phenology, growth, yield and components were collected and analyzed procedurally from all treatment combination units. The results revealed that, majority of agronomic traits were affected by the main effects of NPSB fertilizer rates and genotypes. Number of total tiller, number of productive tiller and spike length were significantly (p<0.05) affected by interaction factors. Maximum value obtained from the application of 225 kgha-1 NPSB fertilizer rate and minimum value recorded from control for all agronomic parameters. The partial budget analysis revealed that the highest net benefit (benefit 150,357.24 Birrha-1) with MRR 280.51%) % was obtained from G-238871 with application of 225 kgha-1 NPSB and all genotypes including check responded to 225 kgha-1 NPSB rate for high yield production and economically beneficial. Based on the result of this study, genotype G-238871 that received 225 kgha-1 NPSB fertilizers was appropriate in the study area but for further realities, the experiment would have to be replicated over the year and location to get a conclusive result and optimum fertilizer recommendation for the specific area in order to ascertain the finding of the current study.
