ABSTRACT:
No-till or minimum tillage planting on ridges has been suggested as a water quality management practice for poorly drained soils. Studies were conducted between 1982 and 1985 on a Hoytville silty clay (Mollic ochraqualf, fine, illitic, mesic) to evaluate corn (Zea. mays L.) and soybean (Glycine max L. Merr.) responses to ridge planting. Corn planted on ridges generally produced yields equivalent to or greater than corn planted following fall plowing for continuous corn and corn-soybean rotations, with or without tile drainage. Soybeans planted on ridges in 76-cm rows generally produced yields equivalent to soybeans planted following fall plowing in 76-cm rows, in corn-soybean rotations, but not always in continuous soybeans. Soybeans planted in 76-cm rows often produced yields lower than those planted in 18-cm rows. In 1 of 2 years in which soil moisture conditions permitted, earlier planting of corn on ridges yielded more than corn planted on fall-plowed plots.
