Effect of chloride fertilization on yield and development rate of winter wheat varieties

The effect of Cl fertility on small grain production is currently of great interest in the Northern Great Plains. Research from South Dakota and Montana has shown that application of fertilizers containing Cl may increase grain production. However, little is known about the mechanism of response. Several studies have found that Cl applications reduced disease severity from plant pathogens. However, the Cl-plant disease relationship does not explain many instances of Cl induced yield response. Chloride has been shown to reduce plant disease severity without affecting grain yield. In other cases Cl has increased grain yield without affecting the severity of plant diseases. This research led to information documenting chloride deficiency and response to chloride in small grain cereals.

Interpretive Summary

1996

Effect of Chloride Fertilization on Yield and Development Rate of Several Winter Wheat Varieties in Montana, 1996 Both non-disease and disease related Cl yield responses by winter, spring and durum wheat have been studied in this 5-year project in eastern Montana with a focus on non-disease leaf spotting that has been observed on certain wheat varieties. Research revealed that wheat yields are frequently improved by Cl fertilization.
