Olive Research for Oregon

The Olea project is a collaboration between Oregon State University (OSU) Extension’s Mid-Valley Small Farms Program and local olive growers.

Olea was initially funded by the Sustainable Agricultural Research & Education (SARE) program of the United States Department of Agriculture (USDA) and is currently funded by the OSU College of Agriculture, OSU Extension.

Olives (Olea europaea)... 

are an innovative crop that offer many opportunities for Oregon small farmers to diversify their farms and generate alternative income from value-added farm products. The Olea Project was established with the goals of making olive production economically feasible and reducing climatic limitations for olive growers during establishment in Oregon’s unique growing conditions.

We are currently conducting research and evaluation of the best practices for both table olives and oil producing olives in Oregon. Our research focuses on propagation techniques, cultivar evaluation, and transplanting and orchard establishment practices, in collaboration with experienced growers and industry professionals. Olives offer growers the opportunity to introduce new revenue streams, take advantage of the crop’s lower water and input needs, and utilize soils considered to be of lesser agricultural quality. Olives are an upcoming specialty crop in the state of Oregon as growers look to diversify and to anticipate future climate and market possibilities.

The primary objectives of the Olea Project:

1. Evaluate the relative winter cold tolerance of olive cultivars through a six-year field evaluation to establish which cultivars are the hardiest and produce the highest quality fruit in western Oregon.

2. Determine the most effective on-farm olive propagation techniques for Oregon by evaluating timing, rooting hormones, and propagation media for successfully rooting locally-adapted cultivars.

3. Assess overwinter, transplanting, and up-potting practices to achieve rapid orchard establishment.  Evaluate how plant size and maturity at planting impacts growth, development, and winter cold tolerance. 

4. Disseminate the information obtained to industry stakeholders, existing and potential growers, project participants, and the general public via written media, online, and in-person communications during and following the duration of the project.
