Ag Census Reveals First Reports of Kiwiberry Production in the Northeast; UNH Leader in Research and Breeding

DURHAM, N.H.—For the first time since the USDA began keeping statistics in 1840, farmers from several Northeast states, including New Hampshire, are reporting kiwifruit production operations. The news comes six years after the New Hampshire Agricultural Experiment Station at the University of New Hampshire launched a kiwiberry research and breeding program.

According to the 2017 Census of Agriculture, which was released earlier this month, two producers in New Hampshire reported kiwifruit production operations, the first time the Granite State has self-reported such production to the census. Other Northeastern states self-reporting kiwifruit farms for the first time include Pennsylvania (eight), New York (seven), Vermont (five), and Connecticut (one).

Nationally, the number of kiwifruit farms increased from 345 in 2012 to 426 in 2017, but this statistic requires some unpacking. According to officials with the USDA National Agricultural Statistics Service, the term “kiwifruit” encompasses all species of the genus Actinidia, including not only Actinidia chinensis var. deliciosa, the fuzzy-skinned, egg-sized fruit most familiar to consumers, but also the smooth-skinned, grape-sized, and more cold-hardy Actinidia arguta, or kiwiberry.

According to Iago Hale, associate professor of specialty crop improvement who oversees the project, fuzzy kiwifruit dominates national production, with more than 95 percent of the total kiwifruit acreage in the U.S. found in California alone. However, small-scale kiwiberry production is on the rise, as indicated by the growth of kiwifruit production in northern latitudes, including the Pacific Northwest (102 farms), the Midwest (11), and now the Northeast (23).

“For well over a century, people have recognized the potential of kiwiberry as a high-value fruit crop in our region,” said Hale. “In 2013, we established a long-term research and breeding program to support its development in an effort to provide the systematic investment needed to move the species out of backyard gardens and into commercial production. The increase in kiwiberry operations in the region is a welcome confirmation that we are where we need to be. As a commercial enterprise, kiwiberry is beginning to establish itself, and we are poised to work with and support these new producers.”

Kiwiberries have an extensive 140-year history of cultivation in New England, first as an ornamental landscape vine and subsequently as a new fruit crop on private estates and in backyard gardens. In more recent decades, a handful of producers have experimented with field-scale kiwiberry production, demonstrating the commercial viability of the crop in the region and developing interest among researchers and consumers. They have an attractive appearance, intense and complex flavor profiles, high levels of bioactive compounds, and are easy to eat.

According to Hale and research technician Will Hastings, who manages the kiwiberry vineyard, there is great potential for growth of a kiwiberry sector in the Northeast due to consumer interest, an established valuation of local produce, the area’s unique culture of direct-market horticultural crops and the low level of regional production to date.

The University of New Hampshire inspires innovation and transforms lives in our state, nation and world. More than 16,000 students from all 50 states and 71 countries engage with an award-winning faculty in top-ranked programs in business, engineering, law, health and human services, liberal arts and the sciences across more than 200 programs of study. As one of the nation’s highest-performing research universities, UNH partners with NASA, NOAA, NSF and NIH, and receives more than $110 million in competitive external funding every year to further explore and define the frontiers of land, sea and space.
