Three tractor cultivations that severely pruned the root systems of hand-weeded plots of sweet corn [Zea mays L. var. rugosa Bonaf., Iochief] grown on a Codorus-Elkton silt loam under extreme drought conditions did not reduce the yield of marketable ears when irrigation totalling 2 acre-inches was applied during pollination and ear-filling. Pre-emergence application of 2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine [atrazine] to the soil surface without cultivation reduced brace root growth and yields significantly in the year of most severe drought. These effects of atrazine were avoided when the herbicide treatments were supplemented with tractor cultivations that covered the brace root zone of the corn plants with soil.

High Vowels

This chapter is devoted to tongue root (ATR or RTR) harmony in Tungusic languages (a.o. Classical Manchu) and Mongolian languages (Khalka and Buriat), which all belong the Altaic language group. In addition to TR-harmony, most Tungusic and Mongolian languages also have a limited form of labial harmony, especially among low vowels. After discussing the Tungusic and Mongolian systems the chapter will focus on the behavior of high vowels, which do not participate in labial harmony, and are either transparent or opaque. A notable difference between Tungusic and Mongolic regards the fact that whereas [i] is transparent to labial harmony in Mongolic, it is opaque in Tungusic. High round vowels are opaque in both groups.
