The What and Why of the Paired-Row Effect on Yields of Cereals

Learn about experiments showing that cereal grains when under pressure from root disease yield more when planted in paired rows spaced 7 inches apart, with 17 inches between the pairs, rather than rows spaced uniformly at 12 inches apart; and that placement of fertilizer as a band needs to be close enough to the seed row so that even diseased roots can access to the nutrients.
