Lettuce / Leafy Greens
Two dozen or more types of leafy greens are grown in New York, primarily for fresh market production. According to the 2007 Census of Agriculture, 224 New York farms produced 1,398 acres of lettuce. Leaf lettuce is the most widely grown with 758 acres, followed by 381 acres of head lettuce and 260 acres of romaine lettuce. Lettuce is grown for local sales as well as large wholesale markets in the Northeastern, US.Other popular greens are spinach (247 acres), collards (96 acres), escarole & endive (75 acres), kale (57 acres), mustard greens (36 acres) and turnip greens (16 acres). Additional types for which no statistical information is available include: arugula, beet greens, bok choy, dandelion greens, radiccho, rapini, swiss chard and watercress.
Field-grown greens are available beginning from May through mid-October (depending on the type). However, the season can be extended by growing in tunnels protected from harsh winter temperatures.

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.

Impact of Minimal Supplemental Heating on Winter High Tunnel Greens
Ethan Grundberg, Vegetable Specialist
Eastern New York Commercial Horticulture
With support from a Northeast Sustainable Agriculture Research and Education program (NE SARE) Partnership Grant (ONE17-298) and the generous cooperation of the Poughkeepsie Farm Project (PFP), I spent much of last winter gathering data from a side by side comparative trial assessing the impact of minimal heating in winter greens production. Specifically, we tracked yield, soil nitrate availability, total plant nitrogen uptake, propane use, and soil temperature all winter in the two identical side-by-side 42'x196' double layer inflated poly Harnois high tunnels at PFP. The only deliberately manipulated variable between the two tunnels was the minimum thermostat setting: one tunnel was set to 33° F ambient air temperature and the other set to 40° F.

Ethnic Greens Trial, 2012
Robert Hadad, Extension Vegetable Specialist
Cornell Vegetable Program
Interest in growing ethnic vegetables has been increasing in our region. In response, the Cornell Vegetable Program conducted a two-year ethnic vegetable variety and marketing trial. The focus of the trial was to see how well assortments of vegetables that represent some different nationalities perform in WNY under our wildly fluctuating weather conditions and also to see how growers can market these new vegetables, how customers respond to them at the market, and what is needed to reach targeted communities perhaps. Funding was provided by the Western NY CCE Association group.
