Nitrogen fertigation practices to optimize growth and yield of northern highbush blueberry (Vaccinium corymbosum L.)

Creator:

Vargas, Oscar L.

Abstract:

Northern highbush blueberry is a long-lived perennial crop that is well adapted to low soil pH conditions. The plants are often shallow rooted and absorb primarily the ammonium (NH₄) form of nitrogen (N) rather than nitrate-N (NO₃-N). Traditionally, commercial blueberry fields have been irrigated with overhead sprinklers and fertilized using...

Spring nitrogen and cultivar effects on winter canola (Brassica napus L.) production in western Oregon

Creator:

Ferguson, Brock T.

Abstract:

Limited information is available on the effects of applied spring nitrogen (N) and cultivar on winter canola (Brassica napus L.) production in high-rainfall environments. The objectives of this investigation were: (i) to determine the effects of spring N and winter canola cultivars on seed and oil production characteristics, and (ii)...
