  • Oilseed Production in the Northeast
    OILSEED PRODUCTION IN THE NORTHEAST A Guide for Growers of Sunflower and Canola Dr. Heather Darby Philip Halteman Hannah Harwood Extension Agronomist Crops & Soils Crops & Soils and Instructor Technician Technician This manual has been developed by the University of Vermont Extension Northwest Crops & Soils Program and is intended to provide the best and most broadly applicable agronomic practice information at the time of its printing. Our aim in writing is for the bulk of this manual to be as useful as possi- ble for as long a period of time as possible. Therefore, we have designed it to address practices that are unlikely to change, while avoiding making specific recommendations for varieties or equipment. More specific information is con- tained in annual trial reports published in the winter and ear- ly spring, available on the UVM Extension NWCS program website (www.uvm.edu/extension/cropsoil/oilseeds). This manual will remain available as a PDF on the website as well. 2 OILSEED PRODUCTION IN THE NORTHEAST A Guide for Growers of Sunflower and Canola Dr. Heather Darby Extension Agronomist Philip Halteman Crops & Soils Technician Hannah Harwood Crops & Soils Technician 3 Copyright ©2013 by University of Vermont Extension Northwest Crops & Soils Program UVM Extension helps individuals and communities put research-based knowledge to work.

ARS is the principal in-house research agency of the U.S. Department of Agriculture (USDA). Congress first authorized Federally supported agricultural research in the Organic Act of 1862, which established what is now USDA. That statute directed the Commissioner of Agriculture “to acquire and preserve in his department all information he can obtain by means of books and correspondence, and by practical and scientific experiments.” The scope of USDA’s agricultural research programs has been expanded and extended more than 60 times since the Department was created.
