STUDIES ON FOOT AND ROOT ROT OF WHEAT: III. EFFECT OF CROP ROTATION AND CULTURAL PRACTICE ON THE DEVELOPMENT OF FOOT ROT OF WHEAT

Abstract

The following conclusions are drawn from a uniform, co-operative, crop sequence study at seven stations in western Canada, viz., Morden, Indian Head, Swift Current, Scott, Lethbridge, Olds and Vermilion, from 1928 to 1932, inclusive (a total of 28 station-years). Foot-rot damage of wheat is significantly reduced where wheat alternates with summerfallow in a two-year rotation, where it follows summerfallow in other rotations, alternates with oats in a two-year rotation, follows oats in a three-year rotation, follows sweet clover in a three-year rotation, or where wheat is sown late. It is increased where wheat follows wheat, barley, or western rye grass.
