M.  aOnion response to phosphorus application strategies and in-season nutrient supplementation.  c2014  ap. 47-56  a(OSU. Special Report, Ext/CrS, 149).  aGerminating 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.  aAdubação  aAllium Cepa  aCebola  aFósforo  aGerminação  aIrrigação  aIrrigação por Gotejamento  aSemente  aOnion1 aSHOCK, C.
