Climate, Field Management Keys to Increased Crop Yields

While plant genetics has been considered the key factor in improving
crop yields, the new IANR analysis which studied data for 3,000
irrigated fields in three Nebraska regions over a 15-year period,
revealed thatclimateand field management, rather thangenetics, had a far
greater influence on increased crop productivity.

IANR researchers found that the 15-year climate trend for the Nebraska
cornfields included in the study accounted for 48% of the yield gain,
while 39% stemmed from agronomic practices, including increased seeding
rates and nutrient inputs and a shift toward corn-soybean rotations
rather than continuous corn. Genetic factors accounted for only 13% of
yield gains.
