Abstract
Teff is one of the important crops grown in the southern region.
Experiments were conducted at
Bobicho research site (Hossana), Areka and Awassa on Profondic Luvisols, Haplic Alisols, and Vitric
Andosols, respectively, to determine NP fertilizers requirement for tef production.
Urea and triple
super phosphate (TSP) were used as sources of N and P, respectively, at Hossana; whereas urea and
diammonium phosphate (DAP) were used at Awassa and Areka as sources of N and P, respectively.
Nitrogen was applied at rates of 0, 23, 46 and 69 kg/ha; whereas P was applied at 0
