2017 and 2018 Lettuce Variety Trial Results
Crystal Stewart-Courtens, Extension Vegetable Specialist
Eastern New York Commercial Horticulture

During the past two seasons we conducted trials of primarily Romaine lettuces to determine heat tolerance as measured by bolting and bitterness. Our trials were located at Pleasant Valley Farm in Washington County. During 2017 we planted three successions. One seeding failed due to a greenhouse malfunction; the other two were transplanted in mid-June and early August, about three weeks after seeding. In 2018 we seeded successions on March 28th, July 15th, and August 1st, all of which yielded good harvests. These trials are more observational than research oriented, and included only one replication per planting.
