Abstract
Ethiopia's most commercially significant vegetable and spice crops is hot pepper. However, due to a lack of soil fertility and other variables, its output is quite poor. In 2020/2021 cropping season, research undertaken to assess the effects of mixed NPSB fertilizer and farm yard manure rates on growth, yield, and yield components of hot pepper. In randomized complete block design with three replications, treatment composed of four levels of NPSB fertilizer and four levels of farmyard manure. Most growth, yield, and yield component parameters were significantly impacted by the main effect of blended fertilizer and farm manure rates and their interaction. Application of 150 kg NPSB /ha rates with 6 t/ha farm yard manure resulted in the highest (2.35t/ha) marketable pod output. In conclusion, by applying 150 kg / ha of NPSB and 6 t / ha of farmyard manure, hot pepper growth, yield, and yield components can be increased.
