Study on the integrated effect of organic and chemical fertilizer levels on bread wheat was conducted in 2013 cropping season at high lands of Adi-golo and Mekan districts of Tigray, Ethiopia with the objective of determining the optimum integration of organic and inorganic fertilization for bread wheat production. The field experiment consists four level of N/P2O5 (0/0, 23/23, 46/46 and 69/69 kg ha-1) and five level of farmyard manure (0, 4, 6, 8 and 10 t ha- 1) arranged in factorial RCBD with three replications. Organic and chemical fertilizer applications had significant (P<0.05) effect on grain yield in the sites. Higher grain yield (5.04 and 2.19 t ha-1) with acceptable marginal of rate return (MRR=1228.9 and 2788.9%) were obtained in the combined application of 46/46 N/P205 kg ha-1+6 t ha-1 farmyard manure and 46/46 N/P2O5 kg ha-1+10 t ha-1 farmyard manure at Adi-golo and Mekan areas respectively. Combined applications of organic and chemical fertilizers are more effective than sole application of organic or chemical fertilizers for sustainable Wheat and soil productivity enhancement.
