Text Appearing Before Image:
CONTROL OF BACTERIAL WILT 13 Tobacco of good quality was produced on urea-treated soil, however, by grow- ing it in rotation with 1 year of corn in small plot trials completed in 1941 (fig. 5). This experiment was repeated in 1943 at five locations, in which the tobacco ripened and cured well. At one location where data were taken on plots in triplicate, the 1,000-pound rate of urea averaged 977 pounds of tobacco an acre that sold for $39.30 a hundredweight, a normal yield and value for the sandy loam soil on which the test was conducted. The quantity of urea required for wilt control, when used in combination with the corn rotation, was investigated on a total of nine replicates at the five loca-
