Report of Accomplishments. Hybrid Corn Tests in Northern New York:

NNY farmers have increased corn yields dramatically over the past 20 years. Grain yields have nearly doubled, and silage yields have increased by over 30%. This provides over $10 million in added value of grain and silage each year to the economy of the region. Many farm practices have contributed, but the identification of superior hybrids in the NNY-ADP extension corn testing project has played an important role in this advance.

NNY farmers face many challenges in selecting corn hybrids for their farms. The Northern NY region has a growing season that is shorter and cooler than other regions of the state. Yet mid-summer days are longer than further south, enhancing light for crop plants. Soils differ both within the region and from other NY regions.

The NNY corn variety testing program is designed to screen about 90 corn hybrids each year, and provides results in recommendations to farmers in the region. 1999 and 2000 tests were planted at the Miner Institute Farm in Clinton County, at the Canton research farm in St. Lawrence county, and on the Ron Robbins farm in Jefferson County. These sites were selected to gain a cross section of environments across the NNY region.

In 2000 year tests, two trials were successful at Sacketts Harbor, Jefferson county. Data is attached. Deer damage was extensive in the test at Canton, rendering the test results unusable. May rains reduced the stand at Chazy, but some data may be usable. We are currently working with this information.

Test results are useful to NNY farmers in selecting corn varieties best adapted to their farms. Results also help seed companies choose which of their hybrids to sell to NNY farmers.

Results from these tests are published annually in testing reports, and in Cornell Recommends for Integrated Field Crop Production. Surveys indicate that the results gain wide use, both by farmers and by industry decision makers.

Funds from the Northern NY Agricultural Development Project provide essential operating support for these variety testing activities. These Project funds serve as "seed" money, and cover "in-region" operating expenses. Salaries and capital costs are covered by other income sources.

Project funds are an important investment in improving feed production for the 4,500 farmers in the region, who contribute nearly $60 million annually in sales of milk and crops to the economy of the region.
