Abstract
Abstract Field studies compared yields between plow‐down and sidedress N and fall, winter, and spring applied P‐K for corn ( Zea mays L.) on Piedmont soil and corn and cotton ( Gossypium hirsutum L.) on Coastal Plains acid soils. There were no significant yield differences for the Piedmont soil. For the Coastal Plain soil over a 3‐year period, winter‐ and spring‐applied P and K were superior to fall applications and sidedress N was better than plow‐down N for corn production. Similar N responses were obtained for cotton. However, there was no difference between the fall‐ and winter‐applied P and K, but the spring application yielded significantly (P—.01) more lint cotton than the fall or winter treatments.
