This book is mainly based on the results of two experiments conducted in similar ecological area of Nepal in 2010 and 2011 by a student of Master of Agricultural science . This book is focused on value of organic manures and how organic manures can substitute chemical fertilizers. The results form the experiments showed that the application of FYM 50% + urea 50% resulted into the highest vegetative growth, yield and B: C ratio. The application of vermicompost, sole or in 50% combination with urea produced lower yield with lower B: C ratio. Thus, from this study it can be concluded that in mid hills of Nepal where the small farmers have less convenience to chemical fertilizers can replace urea by farm yard manure to fulfill half dose of nitrogen for obtaining better yield of sweet pepper and higher net profit as well.
