Dry Farm Tomato Production


A three year project (May 2020 - April 2023) funded by Western SARE.  

Project leader: Alex Stone: alex.stone@oregonstate.edu 

Project coordinator: Matt Davis: davisma3@oregonstate.edu

The overarching goal of the project is to jump-start a dry farm tomato production system for the Willamette Valley of Oregon.

The project is:

1) identifying high performing tomato varieties, rootstocks, and scion/rootstock combinations

2) evaluating soil management strategies (tillage, mulching, compost amendments) with Amy Garrett of the OSU Small Farms Dry Farming Program

3) evaluating profitability (with Tanya Murray of Oregon Tilth)

4) developing a dry farm tomato market (with Lane Selman of OSU and the Culinary Breeding Network, and Amy Garrett of the Dry Farming Institute)
