Hot pepper is one of the Ethiopia's most commercially significant vegetable and spice horticultural crop. However, due to a lack of soil fertility and other variables, its output is quite poor. Moreover, the main obstacles restricting the production are insufficient fertilization and a lack of recommendations on the proper rates of application of organic and inorganic fertilizers. In the 2020–2021 growing season, research was undertaken in Jima Genet district, western Ethiopia, to assess the effects of mixed NPSB fertilizer and farm yard manure rates on the growth, yield, and yield components of hot pepper. In a randomized complete block design with three replications, the treatment was composed of four levels of blended NPSB fertilizer (0, 50, 100, and 150 kg NPSB /ha) and four levels of farmyard manure (0, 2, 4 and 6 t/ ha). Most growth, yield, and yield component parameters were significantly impacted by the main effect of blended NPSB fertilizer and farm manure rates and their interaction. The application of 150 kg NPSB /ha blended fertilizer rates with 6 t/ha farm yard manure resulted in the highest (2.35t/ha) marketable pod output. In conclusion, by applying 150 kg of blended NPSB fertilizers per hectare and 6 t / ha of farmyard manure, hot pepper growth, yield, and yield components can all be increased. The same study must be carried out in every season and location in order to provide thorough recommendations.
