research overview
- I am an applied fruit crop physiologist. My goal is to do practical research and extension on tree fruit production problems that will increase the profitability and strength of the NY fruit industry and fruit growers around the world. My research and extension efforts are in 5 areas: 1. Orchard Systems: My goal is to understand the fundamental principles of orchard system performance in both biological and economic terms. I do in-depth studies at Geneva and applied trials on grower's farms around the state in cooperation with extension field staff (Steve Hoying, Mike Fargione and Kevin Iungerman). Our field trials are evaluated from an economic perspective in cooperation with Gerald White, and Alison DeMarree. 2. Rootstocks: My goal is to evaluate apple rootstocks for adaptability and performance under New York conditions. We are testing rootstocks from around the world including new Cornell-Geneva series of rootstock. This work is done in cooperation with Genarro Fazio of the USDA, Herb Aldwinckle of Plant Pathology and the national rootstock testing project- NC-140. 3. Crop Load and Canopy Management: My goal is to develop improved thinning and canopy management practices that improve fruit size and fruit quality while managing orchard tree canopies at a variety of tree densities. This work is in cooperation with and Alan Lakso, Lailiang Cheng, Duane Greene of U. of Mass and Greg Lang of Michigan State University. 4. Extension Leadership I provide leadership to the fruit research and extension team at Cornell by serving on the advisory committees of all the tree fruit extension specialists. I lead the effort to provide high quality in-service training meetings for extension educators by combining our in-service meeting with Michigan and Ontario Canada. I serve as editor, of the NY Fruit Quarterly which is the primary research reporting magazine that provides the fruit industry with regular communication on the progress of research programs at Cornell.

outreach overview
- My research and extension program is aimed at solving practical fruit production problems that will increase the profitability and strength of the NY fruit industry. My program is largely field oriented and of an applied nature. I am working in 6 areas to accomplish my goals. • Orchard Systems: My goal is to understand the fundamental principles of orchard system performance by studying the effects of tree form, orchard planting configuration and rootstock on light interception and utilization by the canopy and their relation to yield, precocity, fruit quality and pest control. • Rootstocks: My goal is to evaluate apple rootstocks for adaptability and performance under New York conditions. Much of our work over the last 10 years has been to evaluate the performance of the new Cornell-Geneva series of rootstock developed by Dr. Jim Cummins. • Maximizing New Tree Growth: My goal is to study factors influencing the growth and cropping of young fruit trees to maximize early tree performance and reduce the turn-around time and investment associated with orchard renewal. • Crop Load and Canopy Management: My goal is to develop improved thinning and canopy management practices that improve fruit size and fruit quality while managing orchard tree canopies at a variety of tree densities. • Irrigation/Fertigation: My goal is to develop irrigation strategies and scheduling programs that will enhance fruit size and yield of both young and older orchards. • Ecomomics of Orchard Systems: My goal is to develop sound economic evaluations of different orchard systems to assist growers in making wise investment decisions.
