Onion response to irrigation criteria for two varieties at two plant populations. Infoteca-e
PINTO, J. M.; SHOCK, C. C.; FEIBERT, E. B. G.; SAUNDERS, L. D..
Past research at the Malheur Experiment Station demonstrated the sensitivity of onion yield and grade to soil water tension (SWT) (Shock et al. 2000). The ideal SWT for initiating irrigations for drip-irrigated onion was determined to be dose to 20 cb. ln many other countries onions are grown at higher plant populations than in the Treasure Valley. A higher plant population might require a different SWT. This trial tested four SWTs with two varieties and two plant populations .

Onion response to late-season water stress at two plant populations. Infoteca-e
PINTO, J. M.; SHOCK, C. C.; FEIBERT, E. B. G.; SAUNDERS, L. D..
Split 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.

Onion response to phosphorus application strategies and in-season nutrient supplementation. Infoteca-e
PINTO, J. M.; SHOCK, C. C.; FEIBERT, E. B. G.; SAUNDERS, L. D..
Germinating onion seed and new onion seedlings have difficulty obtaining adequate phosphorus (P) for ideal early growth. Low soil temperatures in Oregon and Idaho reduce soil P availability early in the growing season. In addition, soil fumigation to improve onion health can have negative effects, reducing mycorrhizal fungi which enhance nutrient absorption by onion roots. At-planting P fertilization could enhance early season growth. Nutrient supplementation through the drip irrigation system during the season could also result in yield enhancements. This trial tested P application at planting and nutrient supplementation during the season with two varieties and two plant populations.
