ABSTRACT
This study investigated the effects of different Nitrogen
(N) levels and irrigation regimes on yield and yield
components of Onion (Allium cepa L.) at Hawassa area
district, southern Ethiopia in 2012. It was a factorial
experiment laid out in split plot design with three
replications of four irrigation regimes and five N levels.
Data on yield and yield components were collected and
analyzed. Application of N at different levels and
irrigation regime increased total and marketable bulb yield
over the unfertilized plot, and their interaction showed a
significant effect on the average bulb weight; mean bulb
diameter and water productivity of onion. Further increase
in N application beyond 100 kg Nha–1 and
irrigation beyond 75% crop evapo-transpiration ETc did not
bring about significant changes. Therefore, 100 kg Nha-1
and irrigation at 75% ETc can be tentatively recommended for
onion production to the studied area.
Key Words: Onion, Nitrogen Level,
Irrigation Regime, Bulb Yield and Yield Components.
