Barley is produced mainly for human consumption and is one of the most important staple food crops. Lack of integrated nutrient management is one of the limiting factors for barley production. This experiment was conducted at Daniti kebele in Gesha Woreda of Kaffa zone during the 2017 main cropping season to determine the effect of integrated application of Farmyard Manure with N fertilizers on growth, yield components, and yield of food barley and its economic feasibility. Fifteen treatments comprising five levels of N (0, 23, 46, 69, and 92 Kg ha-1) combined with three levels of FYM (0, 0.5, and 1 ton ha-1) were used in a randomized complete block design (RCBD) in factorial arrangement with three replications. Days to heading and physiological maturity were not significantly affected by the integrated application of farmyard manure and nitrogen fertilizer. The interaction effect of farmyard manure with nitrogen fertilizer showed a significant increase in the number of the productive tiller, seed/spike, and thousand-grain weight with the increase in nitrogen levels under all treatments over the control. It was observed that the highest grain/spike (33.67) thousand-grain weight (43.00 g) and productive tiller (177.00 m-2) and grain yield of (3233.00 Kg/ha) was obtained from the combined application of 1 Kg/ha FYM with 92 Kg/ha N fertilizer. The application of this treatment has resulted in the highest net return of Birr 23188.5 ha-1.
