Sorghum (Sorghum bicolar (L.) Moench) is an important cereal crop, which requires high dose of nutrient for optimum growth and productivity. Even though it is highly adapted to different agro ecology, its yield is constrained by declining soil fertility due to nutrient depletion, low level of fertilizer use and unblended application of fertilizer. An experiment was conducted in Shire-mytsebri Agricultural Research Center; at Sheraro sub site in north western Tigray, Ethiopia, during the main cropping season of 2016 with the aim of to evaluate the effects of NPK and blended fertilizers on yield, yield components and economic profitability of selected sorghum varieties. The treatments comprised factorial combination of ten levels of fertilizers (N, P, Blanket recommendation (NP), NPK, NPS, NPKS, NPKSZn, NPKSZnB, NPKSZnB Agricultural Transformation Agency (ATA) and Control (0) and two sorghum varieties (Melkam and Dekeba) tested in a Factorial Randomized Block Design(RCBD) with three replication. A data of Phenological parameters, yield and yield components were taken. There was significant interaction effect of fertilizer treatments and sorghum varieties on most of parameters studied. Significantly higher grain yield was recorded in Melkam (5541 kgha-1) treated by NPKSZn. Biomass yield was obtained higher at NPK from Melkam (21087 kgha-1) and Economic analysis indicated that the application of NPKSZn to Melkam variety accrued the highest gross and net return. Application of NPK to Melkam variety accrued the highest benefit: cost ratio. Even though the highest biomass yield and grain yield were recorded in Melkam treated with NPKSZn but the highest % MRR was recorded for Melkam treated by NPK. Thus, farmers can use fertilizer containing NPK to improve sorghum yield at profitability level.

 

Key words: Blended fertilizer, Dekeba, Melkam, Profitability
