The experiment was conducted under furrow irrigation at Shire-Maistebri Agricultural Research Center (SMARC) Selekeleka research site, in north western Tigray, northern Ethiopia during 2015/2016 (October – June) to study the relationship among growth, yield components and storage parameter of onion (Allium cepa L.).The Correlation coefficient  analysis revealed that marketable  bulb  yield  was  highly  significant  and  positively correlated with  plant height,  leaf number,  leaf length, bulb length,  bulb diameter,  mean bulb weight,  biological yield, total dry biomass  and harvest index. In addition to this, yield was significant association with bulb rotting and sprouting while negatively and statistically in-significant to bulb weight loss.


Key words: Correlation, Onion marketable yield and growth parameters
