This research was conducted to assess the economic feasibility of inorganic fertilizer application and farmyard manure on Marako Fana pepper variety in Raya Azebo district, Northern Ethiopia. The combination of 25, 50, 75 and 100% of nationally recommended inorganic fertilizers and 10 t ha-1 farmyard manure as well as four control treatments (unfertilized, 100% farmyard manure, 100% and blended fertilizer/NPS) were used in this study. The experiment was laid out in a randomized complete block design with three replications. The application of half rate recommended inorganic fertilizer in combination with 5 t ha-1 farmyard manure produced significantly, the maximum total and marketable dry fruit yield of 2.495 and 2.375 t ha-1. Moreover, this treatment was also better than other treatments and generated above the minimum acceptable marginal rate of return. Therefore, it could be concluded that this fertilizer rate could be used in the study area for the production of the variety under irrigation. Hence, to obtain optimum economic return from the production of pepper at the study area, it is recommended to apply an integrated fertilizer management approach.
Key words: Blender fertilizer, marginal rate of return, NP, partial budget.
FYM, Farmyard manure; RNPR, recommended nitrogen and P2O5 rate; NP, recommended NPS rate; RCBD, randomized complete block design.
