M. aOnion response to late-season water stress at two plant populations. c2014 ap. 57-65. a(OSU. Special Report, Ext/CrS, 149). aSplit onion bulbs is a phenomenon where the bottom of the bulb splits open. Split bulbs can reduce onion crop marketable yields. Anecdotal evidence suggests that late-season irrigation interruptions can cause bulb splitting. Past research at the Malheur Experiment Station demonstrated the sensitivity of onion yield and grade to soil water tension (SWT) (Shock et al. 2000a). ln many other countries onions are grown at higher plant populations than in the Treasure Valley. This trial tested the effect of late-season irrigation interruption on bulb splitting at two plant populations with two varieties. aAllium Cepa aCebola aIrrigação aBulbos da cebola Split aEstresse hídrico aOnion1 aSHOCK, C.
