Sorghum is a drought tolerant and nutritious cereal crop usually cultivated for food, feed and fodder by subsistence farmers and its yield is constrained by declining soil fertility due to nutrient depletion, low level of fertilizer use and unblended application of fertilizer in Oromia region, district in East Hararghe Zone. Appropriate (economic and judicious use) of fertilization for a given crop is necessary for sustainable crop production. Experiment on effect of blended fertilizer type on yield and yield components of sorghum crop was conducted in Fadis district of East Hararghe zone at NegawoUmarkule peasant association in 2017/2018 cropping season. It was initiated to evaluate effect of different blended fertilizer type on yield and yield components of sorghum. Eight treatments compromising of different blended fertilizer type with different nutrient content which including NPS, NPSZnB, DAP, NPSB, NPKSB, NPSZn, UREA and control were laid out in a randomized complete block design with three replications. The result of the experiment indicate that there is significance difference among treatments and all blended fertilizer types were improve growth and yield components Of sorghum crop as compared to control. However, application of 100 kg/ha of NPS, NPKSB and NPSB were more increase the plant height, panicle length and grain yield of sorghum than nil fertilizer application and control in the growing year. The highest grain yield (3748.6 kg/ha) was recorded from treatment with application of 100 kg/ha NPS. These result were 45.8%, 70.7% and 75.3% more yield improvement over the control treatment, 100 kg/ha UREA treatment and 100 kg/ha NPSZn treatmentrespectively. In general, Blended fertilizer increase growth and yield component of sorghum due to the blend of different nutrient which are crucial for plant growth. Therefore, based on the result obtained from this study application of 100 kg/ha of blended NPS and NPSZnB are recommended for sorghum production in Fadis area of Eastern Hararghe zone.
