Becky Sideman
Extension Professor/Specialist, Sustainable Horticulture Production


Biography


Becky has worked at UNH since 2004 under a split appointment as an associate professor of plant biology (20 percent) and a Cooperative Extension sustainable horticulture specialist (80 percent extension/applied research). Before coming to UNH, she worked as a plant geneticist and lettuce breeder with the USDA Agricultural Research Service in Salinas, California. She grew up with plants and agriculture on a diversified New England farm in Vermont.


Current Research

  • APPLIED RESEARCH Like the typical highly diversified New England farms I work with, my research interests incorporate a wide variety of crops and research topics. Sustainable production of fruit and vegetable crops in N.H. requires growers to minimize production costs and ecological impacts, while producing economically viable yields of high-quality crops. I choose applied research projects to help New Hampshire growers select crops and growing practices that will reduce inputs and increase farm profitability.

  • Season Extension Prolonging the relatively short New Hampshire growing season can help farmers harvest crops over a longer period and allow them to plant crops that take a longer time to mature than we normally have. Season-extending techniques growers currently use in New England include unheated tunnels (similar to greenhouses) and ground-warming mulches and row covers made of different materials. We need to research the best ways to use these season extension technologies, and to determine in which situations and for which crops they will prove most cost effective.

  • Colored Sweet Bell Peppers (2005, 2006) Ripe (colored) sweet bell peppers have superior flavor and are more nutritious than their unripe (green) counterparts. Ripening requires an additional two or three weeks after fruits are mature green. During this time, fruits become increasingly susceptible to pests and other production problems. In 2006, the second year of sweet pepper trials at UNH, we grew 26 varieties of sweet peppers at the Woodman Horticultural Research Farm - the 12 varieties we tried during 2005, plus 14 new varieties. The goal was to identify varieties that produced high yields of quality colored (red, yellow or orange) fruit early in the season.

  • Sweetpotato (2006) Sweetpotatoes have potential as a niche fall specialty crop for New England growers. I use the term sweetpotato (all one word, rather than sweet potato) to avoid confusion with regular (Irish, or Solanum) potatoes. Consumer appeal for sweetpotatoes is increasing, due to awareness of high nutrient content, flavor, and keeping quality. In a preliminary trial in summer 2006, we grew and harvested 18 varieties of sweetpotato at UNH. Varieties differed for marketable yield and quality characteristics. Despite a late planting date due to wet spring, we obtained high yields for several varieties. The goal was to find varieties that produced high yields of good quality medium-sized tubers with fairly uniform and attractive root shapes. As a specialty crop, varieties with unique flesh and skin colors may be particularly interesting. Because good eating quality is also essential, we also conducted a taste test using 40 untrained tasters at UNH after harvest.


Educational Background

  • 1999. Ph.D., Plant Genetics, Cornell University

  • 1994. B.A., Biology, Dartmouth College


Program Specialty Areas

  • AREAS of EXPERTISE: Sustainable agriculture, vegetable and small fruit production, plant breeding and genetics, plant disease resistance and pathogen interactions, plant pathology and disease management

  • EXTENSION: As Extension Specialist in Sustainable Horticulture, I work with county-based extension educators to provide up-to-date information about the most sustainable production techniques for commercial vegetable and small fruit growers throughout the state. This means developing and delivering educational workshops, making site visits to farms around the state, and conducting applied research (see below!). I also publish the NH Vegetable and Fruit Newsletter. Please email me or call (603)862-3200 if you would like to be notified when new issues become available.

  • TEACHING: Plant Biology 405, Organic and Sustainable Food Production. Next offered: Fall 2012
    In this course, students learn the scientific and biological principles used to develop organic farming techniques and methods, and explore the shared responsibility of producers and consumers for defining how food is grown. The class includes field trips and the opportunity for hands-on learning. It satisfies the Environment, Technology & Society Discovery requirement.
