Plant Breeding – WSU Mt. Vernon

The Plant Breeding program at NWREC concentrates on crops that fit into diverse annual and perennial rotations on small and mid-sized farms. Farmer participatory approaches and other innovative methods are utilized to improve crops such as small grains. Research is prioritized to favor producer groups and crops that are not being served by conventional research programs and approaches.

Understory Management in Organic Orchards

Trials examined weed control, soil quality, tree nutrition, and water use. Also monitored for voles, and testing potential for mulch to host nematodes for control of codling moth larvae. David Granatstein, WSU CSANR, Wenatchee.

Organic Farming Systems

In 2003 an organic vegetable production systems experiment was established on organically certified research land at WSU Puyallup. The experiment compares 12 organic management systems, including three cover cropping systems, 2 tillage treatments, and 2 amendment types, arranged in a split-split plot design.

Organic Raspberry Root Rot Control

Dr. Carol Miles, WSU Mt Vernon Research and Extension Center, and Dr. Pete Bristow, WSU Puyalllup, are investigating organic options to control root rot (Phytopthora fragriae var. rubi). This study is focused on organic root rot control, however all raspberry growers will benefit from new disease management options.
