Four corn seeding rates, 12, 15, 18, and 21k /acre, and two hybrids, 95 and 108 day maturities, were tested across three stubble height treatments, 28, 10, and 4 inches. The test was conducted at 3 locations in 2006 and 3 locations in 2007. Stubble height impacts optimal plant populations for High Plains dryland corn production under some conditions.
