Dry Farming Demonstration

Four sites in Western Oregon hosted Dry Farming Field Days in 2016!

Nearly 200 participants attended one or more of the 2016 field days to learn more about dry farming, see crops (tomatoes, squash, melon, potatoes) grown without any supplemental irrigation in the field, observe roots from soil pits in irrigated and dry farmed plots, do side-by-side tastings of dry farmed and irrigated tomatoes and melons, and talk to experienced dry farmers.

The Dry Farming Collaborative - initiated in Spring of 2016

We are a group of growers, extension educators, plant breeders, and agricultural professionals partnering to increase knowledge and awareness of dry farming management practices with a hands-on participatory approach. So far there are about 20 sites throughout Western Oregon that are hosting dry farming trials including three OSU sites (NWREC, SOREC, and OCCUH).

Are you experimenting with dry farming? If so, we would love to hear about it! To learn more about this participatory research project and see pics from our 2016 trials, visit the Dry Farming Collaborative page on Facebook and/or contact Amy Garrett to join the email list. Dry farming trial hosts and those intereted in learning more about dry farming will be convening this winter for a grower's meeting to share results and discuss future directions for our collaborative research.

Marketing Dry Farmed Produce

Label as dry farmed to increase awareness and include signage to help explain dry farming:

  • Signage for Dry Farming - print and post next to your dry farmed produce at the market to help you explain what dry farmng is, how it works, and where to go for more information.

Dry Farming Demonstration launched in 2015 in Corvallis

In 2015, three 10’ x 100’ plots were established at Oak Creek Center for Urban Horticulture (OCCUH) to demonstrate dry farming management practices in several crops including dry beans, tomatoes, potatoes, squash and melon. Varieties and management practices were selected based on interviews with several established growers experienced in dry farming. Absolutely no irrigation was applied to these plots.
[See results and pics below on this page]
 
This project is funded in part by the National Institutes of Food and Agriculture under the Beginning Farmer and Rancher Development Program.

See articles on this dry farming demonstration in the Capital Press as well as the 2015 Summer edition of Oregon Small Farm News!

2015 Dry Farming Field Day

A Dry Farming Field Day was held on August 3, 2015 at the Oak Creek Center for Urban Horticulture (844 SW 35th St.) in Corvallis, Oregon. More than a hundred farmers and gardeners attended to learn more about growing without irrigation and do taste comparisons of dry farmed and irrigated melons and tomatoes.

January 2016 - 2015 Dry Farming Demonstration Data

2015 Dry Farming Demonstration Data

October 21, 2015 - The winter squash were weighed and yielded as follows with 20 sq ft/plant (4' in row and 5' between row spacing):

  • 'Zeppelin' Delicata: Average of 8 lbs/plant or 8.6 tons/acre
  • 'Stella Blue': Average of 12 lbs/plant or 13.1 tons/acre
  • 'Blue Hokkaido': Average of 16 lbs/plant or 17.4 tons/acre

Knott's Handbook for Vegetable Growers (Table 8.9 on pg. 421) considers 400 cwt or 20 tons/acre a good yield for winter squash. Each of these varieties yielded less than that but absolutely no irrigation was used.

September 28, 2015 - Dry bean plants were pulled on September 11th, left in the field to dry for a couple of days, then moved into the greenhouse and await threshing. Winter squash was harvested on September 25th. Yield data will be taken on these and posted on this page when available.

Dry bean plants were pulled on 9/11/15          Blue Hokkaido, Stella Blue, and Zeppelin Delicata Squash were harvested on September 25, 2015

August 10, 2015 - 20 row ft of 'Yukon Gold' potatoes harvested today! Each plant yields 4 lbs on average at 2.5 ' plant spacing.
