An experiment was executed to investigate effects of different blended fertilizers on yield and yield components of food barley (Hordeum vulgare L.) on Nitisols at Hulla district, Southern Ethiopia. The experiment comprised of 12 treatments viz. control, recommended Nitrogen and Phosphorous, 50 NPS, 100 NPS, 150 NPS, 200 NPS, 250 NPS, 50 NPSB, 100 NPSB, 150 NPSB, 200 NPSB and 250 NPSB kg ha^-1 blended fertilizers; and was laid out in RCB design with three replications. The significant effect of blended fertilizers were observed on barley yield and yield components. Results revealed that the highest above ground biomass (12.63), straw yield (7.73) and grain yield (4.9 t ha^-1) response were obtained with application of 200 kg ha^-1 of NPSB blended fertilizer and is superior on grain yield by 22.4 and 70.4% to recommended N and P and control respectively. Besides, marked nutrient recovery and agronomic nutrient use efficiency was obtained at 100 and 50 Kg ha^-1 NPSB blended fertilizers respectively. The highest net return of 52,068.00 Eth-birr ha^-1 with MRR of 2277.3% were obtained from application of 200 kg ha^-1of NPSB blended fertilizer. Therefore, based on the yield response and economic indicators, it is recommended to apply 200 NPSB kg ha^-1 blended fertilization at Hulla district, Southern Ethiopia and areas with the same soil conditions and agro-ecology.

Keywords: Blended fertilizers, soil test based fertilizer recommendation, barley and nutrient use efficiency
