Small-Scale Fresh Market Potato Variety Trial Results

Margie Lund, Extension Vegetable Specialist
Cornell Vegetable Program

December 15, 2022

This year, the Cornell Vegetable Program planted a potato variety trial focused on commercially available fresh market potato varieties, with the small-scale potato grower in mind. This trial allowed us to test different varieties of potatoes that might be of interest to consumers at farm markets and see how well they perform in a western NY climate. In this overview, we share overall yield results from the trial as well as some details on some stand out varieties. 

Marketable Yield (cwt/A)Marketable yield of all varieties in this year's small-scale fresh market potato variety trial. Varieties are color coded according to skin color (yellow, red, white, purple, and russet). Vivaldi highly outyielded all other varieties, and Norwis performed the worst in the trial.
  • Vivaldi (yellow skin, yellow flesh) was a standout variety in the trial and the highest yielding yellow skin variety. In our trial, Vivaldi showed some netting and scab, but otherwise performed well.
  • Baltic Rose (red skin, yellow flesh) was the standout of the red skinned varieties and second highest performer in the trial overall. This variety showed some scab as well as color variation among tubers and skinning, but overall tubers were a nice size.
  • Among the white skinned varieties, Upstate Abundance (white skin, white flesh) performed the best with tubers looking very nice with smooth skins.
  • In the purple skinned varieties Magic Molly and Blackberry (both varieties purple skin, purple flesh) were neck and neck. Magic Molly produced nice oblong tubers and Blackberry produced deep purple round tubers, both with some scab and skinning present.
  • Lastly, we grew two russet varieties in this trial, with Caribou yielding the highest. However, due to our hot summer we did see a large amount of internal browning in this variety.

Intro to Food Safety and GAPs Training

February 19, 2025
via Zoom,

This virtual workshop will serve two purposes: 

  • For produce farms just interested in learning about farm food safety, this program will introduce principles and best practices.
  • For produce farms look for a GAPs (Good Agricultural Practices) training needed to meet buyer demands for audit/certification, this program will provide that as well.

Laser Scarecrows to Deter Birds in Sweet Corn

Are you considering the use of a laser scarecrow to deter birds on your farm? Cornell Cooperative Extension and the University of Rhode Island teamed up to test a research laser scarecrow on sweet corn farms.

A laser scarecrow is a device that has one or more laser modules connected to motors. The specifications of the lasers are optimized to the color and motion sensitivity of bird's eyes. When laser beams move across a field, birds become frightened and attempt to move away from the perceived threat. Light from the laser covers an area quickly and moves through the canopy without causing injury to the crop. Research demonstrates that birds do not readily become habituated to the laser.

A laser scarecrow used as the sole deterrent typically results in a significant reduction in crop damage. Combined with an auditory device, damage can be reduced even more. When used as part of an integrated management program for bird control that utilizes habitat management and multiple scare tactics, laser scarecrows can be useful tools for growers of multiple crops. All scare tactics must be deployed before birds find the field. The effectiveness of lasers depends on multiple factors such as bird species, bird populations, habitat and food availability. Lasers are not effective at deterring deer, racoons, coyotes or other mammals.

To learn more, the Laser Scarecrows to Deter Birds in Sweet Corn and Other High-Value Agricultural Crops fact sheet provides background information, research data, FAQs, and Advantages/Limitations on laser scarecrows.

NY Urban Farms Pest Management Fact Sheet Series

Cornell Cooperative Extension has partnered with dozens of urban farms across New York State to demonstrate and evaluate sustainable pest management strategies. Together with farmers, we found success using control methods that prevent or reduce crop losses through exclusion strategies, crop timing, host resistance, the introduction of beneficial organisms, and more. Regardless of management strategy used, common requirements for success include a knowledge of the pest and disease complex, preventative deployment and commitment to the process. The New York Urban Farms Sustainable Pest Management Fact Sheet Series includes case studies highlighting pest management techniques that New York urban farms have found valuable.

NYS Urban Growers Pest Management Needs Assessment

As part of a multi-year project exploring non-spray pest management options that are economically and environmentally sustainable for urban farms, we conducted a needs assessment with urban growers across New York State. The New York State Urban Growers Pest Management Needs Assessment presents findings on current pest management practices, challenges, and topics of future interest.
