Onion response to phosphorus application strategies and in-season nutrient supplementation.

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.
