Field studies were done in the EndaMokeni district to see the effects of blended NPSZn levels on barley yield and yield components. The experiments were laid out in a randomized complete block design (RCBD) with seven blended NPSZn levels (0, 50, 100, 150, 200, 250, and 300 kg ha−1) and a general recommendation of nitrogen and phosphorus as 8th treatment in three replications. The output of the result depicted that barley yields improved as blended levels increased, and the maximum grain yield was attained at 300 kg/ha even though it was statistically similar with 100 and 250 levels. Additionally, the straw and grain yields achieved from applying the recommended NP were statistically comparable with 250 kg/ha NPSZn levels. However, the NPSZn blend’s phosphorus levels (150–250 kg ha−1) are significantly greater than those of the recommended NP. Moreover, the highest agronomic efficiency and partial factor productivity were also obtained at NP fertilizer as compared with the increasing NPSZn rates. Hence, the mixing of S and Zn to the conventional NP in the current formulation had no impact on the barley’s grain and straw yields as compared to the conventional NP fertilizer. In this regard, N and P are the most barley yield- limiting nutrients in the EndaMokeni district. Additionally, adding Zn to the blending didn’t increase the barley grain’s Zn concentration. According to the results of the partial budget analysis study, the marginal rate of return was increasing up to 300 kg/ha NPSZn levels. Hence, further blending formulation is important for the potential yield production of food barley in the area.

“…On the contrary, Ethiopian agriculture is a highly exploitative type in which plant nutrients including potassium is extracted from the soil where by very little or no crop residues are returned back to the soil. Additionally, the levels of K in Ethiopian soils were found to be below the ideal threshold for sufficient crop production [15,16]. In line to this, soil with Ca: K > 50:1 and Mg: K >15:1 are likely to respond to potassium fertilization [1].Similarly, the Soil Fertility Atlas of Tigray region indicated a potassium deficiency in various parts of the region including Enderta [17].…”

Recently the government of Ethiopia has introduced potassium as fertilizer through the introduction of various K containing blended fertilizers. However, the optimum application rate and time of application on specific crop and soil type has not been studied yet. So, a field experiment was conducted to determine the optimum rate of potassium and its application time for wheat yield and yield components in Cambisols of Enderta district South Eastern zone of Tigray. The experiment was laid out in Randomized Complete Block Design with 4 levels of potassium (0, 40, 60 and 80 of K2O kg/ha) with and without split application including control in three replications. Results depicted that except harvest index all the yield and yield components of wheat were influenced by potassium fertilization. Moreover, split application of K significantly affected the yield and yield components of wheat as compared to single application of full dose of K. In line with this, the highest grain and straw yields of wheat were obtained at 80 kg/ha K2O levels and statistically similar with the split application levels of 40 and 60 kg/ha K2O. This implies that the 40 kg/ha K2O at split application is economically feasible (optimum) level of K for wheat production in the Cambisols of the area studied. The highest agronomic efficiency and partial factor productivity were also obtained at the level of 40 kg/ha K2O in split forms. Hence, potassium fertilization is important and should be applied in split methods rather than at full single dose at planting for increasing wheat yield and improving agronomic efficiency and partial factor productivity in the Cambisols of Enderta districts.

“…Wheat trogen utilization, and enhancement of initial growth and in insect and disease confrontation. It has role in transportation of food from the leaves to the other parts of plant body, quality of fruits and seeds, encouraging the roots, strengthening of stem and branches of plants and reduces lodging (Brhane et al, 2017). It is selective and basic supplement for plant metabolism improvements.…”
