The trails are evaluating winter lettuce production methods for the North Country.<hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding"><hr class="invisible minimal-padding"><img src="https://cdn.andnowuknow.com/legacyWriterImages/lettucecash031213ban.jpg" alt="images031213" /><hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding"><hr class="invisible minimal-padding">The research could promise a high payoff value if successful and cost-effective under North Country conditions as consumers appear willing to pay up to $12 per pound for lettuce-based salad mixes on a year-round basis, according to a news release. The Northern New York Agricultural Development Program-funded trials are conducted at the Cornell University Willsboro Research Farm in Willsboro, New York.<hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding"><hr class="invisible minimal-padding">Cornell University researchers and extension specialists are investigating the use of prototype low-wattage heating strips to warm the soil to increase lettuce production during the winter months in St. Lawrence and neighboring counties.<hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding"><hr class="invisible minimal-padding">According to the report, Cornell University Cooperative Extension Vegetable Specialist Judson Reid says, “This research in northern New York is the first attempt at developing a system for heating the greens-growing environment inside high tunnels using heating strips primarily designed for in-floor radiant heat.”<hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding"><hr class="invisible minimal-padding"><img src="https://cdn.andnowuknow.com/legacyWriterImages/lettucecash031213body2.jpg" alt="images031213" /><hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding"><hr class="invisible minimal-padding">Amy Ivy, Cornell Cooperative Extension Horticulture Educator for Clinton and Essex counties, says, “While spinach can be grown and harvested year ’round in northern New York with a minimal addition of heat largely in January and early February, lettuce crops are more cold-sensitive. Our question is can growers cost-effectively add heat to grow the salad greens year ’round without sacrificing profitability.”<hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding"><hr class="invisible minimal-padding"><img src="https://cdn.andnowuknow.com/legacyWriterImages/lettucecash031213body1.jpg" alt="images031213" /><hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding"><hr class="invisible minimal-padding">The 8- or 15-watt electrical heat strip prototypes were buried eight inches below the soil surface in the 30-by-96-foot Ledgewood pipe-frame high tunnels at the Willsboro research farm to warm the lettuce production beds during the night. Production beds were blanketed with a double layer of rowcovers supported by wire hoops that straddled the beds to retain heat around the plants.<hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding"><hr class="invisible minimal-padding">Black seeded Simpson head lettuce plants were transplanted from indoors to the tunnels on February 6th and Five Star baby lettuce mix seed was planted directly into the high tunnel growing beds on February 8th.<hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding"><hr class="invisible minimal-padding">Reid notes, that on nights when the outdoor temperature dropped into the teens and single digits, the soil temperature at 1.5-inch depth in the heated lettuce beds with rowcovers never dropped below 40 degrees Fahrenheit.<hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding"><hr class="invisible minimal-padding"><a class="btn btn-sm btn-primary col-lg-12" style="white-space: normal;" href="http://www.nnyagdev.org/wp-content/uploads/2013/03/NNYADPWinterGreensPR.pdf" target="_new"> Northern New York Agricultural Development Program</a></p><hr class="legacyRuler"><hr class="invisible minimal-padding"><hr class="invisible minimal-padding">
