Abstract
Field experiments showed that disking of rye straw in early June, rather than at the normal time in mid-July, reduced the population of the root lesion nematode in the roots of the subsequent crop of tobacco as effectively as nematicides. However, summer fallowing tended to lower the nitrogen content of the soil and supplementary nitrogen was required to obtain normal yields of tobacco.
