AB  - In Ethiopia, sesame is the leading oil crop followed by Niger seed and linseed; and oil seed is the third largest sector after cereal and pulse. Production and productivity of sesame is greatly affected by lack of optimum fertilizer rate, inappropriate sowing time, lack of optimum plant population, biotic and a biotic factor such as disease and pest infestation, low yielding variety, post-harvest lost, low fertilizer response, difference in capsule maturity, shattering etc. The study was carried out in 2018 main cropping season at Uke in Guto Gida District of East Wollega Zone of Oromia Regional State with the objectives of investigating the effects of NPS fertilizer rates on yield and yield components of sesame varieties.
