With the hot summers of recent years causing significant heat damage to broccoli heads within the Willamette valley, varietal screenings for newer and more heat tolerant varieties became necessary. Most commercially available broccoli varieties are bred for production within milder and more climatically stable regions, such as the Salinas Valley...
This research has demonstrated that liming clubroot infected soils to a pH ≥7.1 is an effective practice for reducing both the incidence and severity of clubroot. Liming does not kill the pathogen but rather prevents disease spores from infecting the plant. This research demonstrated that highly reactive calcitic lime products...
The goals of this project were to determine 1) if liming controls clubroot, 2) the pH that must be attained to achieve commercially viable levels of control, and 3) how best to lime (materials, timing, incorporation strategies) to achieve that pH.
This bulletin is one of a series on organic potato production developed by “OSPUD.” OSPUD is a collaboration among Oregon State University personnel and 11 farmers operating diversified organic vegetable farms. The purpose of OSPUD is to improve potato quality and profitability through a participatory learning process and on-farm, farmer-directed...
Varieties of several kinds of vegetables were observed in conjunction with breeding programs. Unless otherwise noted, plots were 10–20 feet long, in 36-foot rows, and received about 450 lb/acre (about 10 lb/1,000 ft2) of 12-29-10-4 fertilizer banded prior to planting. Water was applied every 7–14 days as needed. The soil...
1. Rotbusters Field Survey.
Kokanee and Basin were the only varieties sampled in 2005. There was a significant relationship between radicle rot severity and gross yield for Kokanee but not for Basin.
In previous years, we have shown that for Jubilee, approximately 3 tons of gross yield are...
Objective: to evaluate the impacts of N availability, microbial activity, and root health on corn productivity and yield in high biomass cover crop systems
1) Develop and moderate a workshop to discuss hypothetical crop rotation strategies that would
allow conversion of land to organic processed vegetable production without exacerbating weed
or pest positions.
• Invite industry leaders to help develop crop rotations
• Invite potential forage consumers/buyers to help focus on projected forage needs...
Objectives: to determine the impact of
1.fall Contans applications on Coniothyrium minitans (Cm) infection and survival of sclerotia left on the soil surface through the winter and summer
2.the impact of summer irrigation and burial on sclerotial survival and infection with Cm and other fungi
