Abstract
Abstract The effect of 10° to 15° F. increase in field soil temperature on growth, yield, and ion accumulation by corn was investigated. In Ohio, normal field soil temperatures are below optimum for maximum corn plant development. Increasing soil temperature with heating cables installed beneath the row accelerated the rate of plant development, and produced significant increases in dry matter production and corn yield. Soil heating significantly increased N, P, K concentrations in plants sampled 30 days after planting. Soil heating did not significantly affect the composition of plants sampled at 60 days or at maturity.
