Baby-leaf Salad Greens
Project Overview

Baby-leaf salad greens are a popular crop and have the potential to be a viable source of income for small-scale direct-market farmers during the spring and fall seasons. In our project, we evaluated the performance of 10 varieties for baby-leaf salad green production in replicated variety trials at WSU-Mount Vernon Northwestern Washington Research and Extension Center and at Cloud Mountain Farm Center in Everson, WA. We measured total and marketable yield, days to harvest, and weed weight in the spring and fall for 2 years. Postharvest shelf life of each variety was also evaluated visually (decay, discoloration, wilting, and visual quality) twice per week after harvest.
For an overview of our project, see Evaluating baby-leaf salad greens for spring and fall production in Northwest Washington.
We have summarized all we learned from this project regarding baby-leaf
salad production into our new production guide:
