Abstract:

The present research was intended to study the effect of different levels of NPK fertilizer on the yield and yield attributes nutrients contents, uptakes and use efficiency of barley in Wolaita zone, southern Ethiopia. The experiment was laid out in randomized complete block design with replicated three times of three nutrients three rates for N (0, 23, 46 kg ha-1) and K (0, 25, 50 kg ha-1) and four rates for P (0, 10, 20 and 30 kgha-1), the total treatment combinations and the rates of P are basis of common practices of fertilizer application on barely production, Soil samples were collected before sowing from the depth 0–20 cm soil layer from each sites. The results showed that different rates of NPK had significantly (p<0.05) affected plant height, spike length, grains spike-1, grain and straw yield, nutrients content, total nutrient uptakes and use efficiencies. Maximum grain yields were obtained from N46P30K50 kg ha-1, nutrients content and total uptakes were increased with increasing rates but decreased in use efficiencies in both sites, OC, TN and available P were low in all locations. Conclusion: Based on these results, nutrient supply and use efficiency and yield from fertilizer application will be required to sustain the productive capacity of the soils in other part of Wolaita zone and reveals to what extent changes in input parameterization of nutrient requirements of barley.
