Precise seeding rates for cotton have become practical since the introduction of air planters designed for agronomic crops. Cotton seeding rates in Georgia average about 3/ft, with a range of just under 2 to over 5 seed/ft. With these relatively low rates, it was thought that there might be a local cost advantage for genetically engineered cultivars based on the assumption that costs would be built solely into the price of seed. [In retrospect, this assumption about cost was correct for some technology but not others. ] While reduced seeding rates may lower costs, they may also create a need for greater weed control inputs.
