Overview

My research and extension program revolves around investigating dry bean and potato responses to our highly variable environment, as well as changing utilization needs, and concerns about the long term sustainability of these industries and the environment. Working with other researchers, Cornell Cooperation Extension staff, industry and collaborators in several other states, I develop research and Extension projects to find information which can link various components of the cropping system and provide guidelines on how to best use them.

Research Focus

By working with other researchers, breeders and extension staff (in several Cornell departments, in New York State and nationally) associated with both dry bean and potato crops, I have the closest linkage possible to the newest breeding lines with the best potential for production in New York. This allows me to work with these new materials and develop appropriate cultural practices, utilization recommendations and yield assessments which will assist growers in successfully adopting these new varieties.

Outreach and Extension Focus

My Extension activities range from hands-on instruction of growers or Extension field staff to working on national committees and workgroups for both dry bean and potato commodities. Goals for working with growers and industry groups include educating those individuals about the reason why crops respond the way they do given our environmental constraints in the Northeast. If they can better understand the biological and physiological basis for plant response, then they can do a better job making the right cultural and management decisions with their crops. Working with Extension staff and commodity workteams helps provide a wider perspective of industry needs and problems statewide and nationally.
