Processors need broccoli with better quality traits than what is available in cultivars developed for California and Mexico fresh markets. Farmers need to reduce labor costs of broccoli production by mechanizing harvest. Most contemporary commercially available cultivars are not suitable for either mechanical harvest or processing. The objective of the OSU broccoli breeding program is to develop broccoli varieties adapted to western Oregon with suitable quality and high yields. The program operates on a one year cycle where cuttings from the field are taken into the greenhouse in the fall where they are rooted and hand crossed and self-pollinated to produce seed for the next generation. Seed is harvested in May and June and used to plant trials for fall evaluation. In 2015, nine experimental hybrids were planted in a replicated yield trial, which also included two commercial check hybrids and a new exserted commercial hybrid from Seminis.

Five insects contaminate broccoli in the Willamette Valley: cabbage loopers (Trichoplusia ni), cabbage white butterfly larvae (Pieris rapae), diamondback moth (Marrtestra aphids (Brevicoryne brassicae). Broccoli is inspected very closely before it is accepted for processing. Low levels of insect contamination result in the rejection of truckloads of harvested broccoli by processor quality assurance programs and thousands of dollars of loss to growers.

Objectives:

  1. Determine the potential selective herbicidal activity of three nitrogen-containing fertilizer solutions.
  2. Compare broccoli response to nitrogen applied in these foliar sprays to equal amounts of nitrogen applied in the usual form of side-dressed fertilizer.

The Cabbage Aphid can cause significant economic loses in broccoli grown in the Willamette Valley (Figure One). The feeding of the aphid on the broccoli plant may reduce yield slightly, but the real damage it causes is contamination. The cabbage aphid contaminates the harvested heads of broccoli. This can result in rejection of entire loads of broccoli by the quality assurance program of broccoli processors. Once the aphids have moved up into the developing broccoli head, it is possible to kill them, but it is no longer possible to remove them as a contaminant.

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. Research conducted in 2014 showed 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. In 2015 the research was focused on the relationship between disease incidence and severity when pH <7.1,better understanding when to apply lime, and how to incorporate to maximize pH change.

Rodents are an increasing problem in fields and pastures. Birds of prey play a vital part in integrated pest management of rodent pests. Living on The Land — Attracting Birds of Prey for Rodent Control succinctly describes the value to farmers and ranchers of attracting barn owls and American kestrels for rodent control, and ways to help build up local populations of these birds.
