An experiment was conducted over two years on a Typic Haplaquoll and an Aquic Argiudoll to determine the effect of tillage on the response of two corn hybrids (Zea mays) to soil K fertility. Four tillage systems were used: moldboard plow, chisel plow, disk, and no-till. The soil K treatments were 336 and 560 kg exchangeable K/ha and 336 kg exchangeable K + 73 kg banded K/ha. Increase in exchangeable soil K increased midseason leaf K each year. Banded K increased leaf K only in the drier year. Tillage affected grain yields only in the growing season with the higher precipitation. The lowest grain yields were obtained with the no-till system, the highest with the chisel system. Potassium treatment did not affect grain yields. It was concluded that K fertility recommendations developed for moldboard plow systems are adequate for reduced tillage systems. |
