Chemical Composition, Nutrient Absorption, and Stalk Rot Incidence of Corn as Affected by Chloride in Potassium Fertilizer¹

Abstract

Synopsis High rates of chloride had little effect on the percentage of other elements in corn leaf tissue in field experiments, whereas total absorption of phosphorus, nitrogen, and magnesium was affected in pot experiments. Stalk rot incidence was decreased with increased potassium chloride applications but not with increased potassium sulfate and potassium metaphosphate applications.

Effect of wheat cultivars, fertilizers, and fungicides on Fusarium foot rot disease of wheat

“…Gunfer et al (1980) and Heitefuss (1989) reported in their studies that fertilizers supplemented with potassium raised plant defense mechanisms against cereal rust, powdery mildew, and foot rot diseases of wheat. Younts and Musgrove (1958) found that potassium induced nitrate uptake and organic nitrogen substances in plants. These reactions and fertilization programs may have changed the direction of the disease progress in wheat plants infected with F. culmorum.…”

Yield and chemical composition of Dactylis glomerata as influenced by genotype and management

“…In general both N and K source tended to influence P content however this varied with sample period as shown in Table 54, Applied N significantly influenced the total N content at all sampling periods (Table 53)» The general nonsignificant effect of K sources on total N content agrees with results reported on corn by Younts and Musgrave (1958) and on Bermudagrass by Adams et al (1967).…”

“…Also, Younts and Musgrave (1958) observed no K content differences on com from a K source of chloride or sulfate.…”

“…in which they state that heavy applications of KCl will result in lowering the uptake of both Mg and P, But absorption of N as rather than as NO3, tends to decrease the uptake of Mg and increase that of P. Younts and Musgrave (1958) report on work of Shestakov and Shvwidenkov in which they found that flax, sunflowers and potatoes absorbed chloride in a linear relationship to the rate of application while P content decreased as a result of increased chloride applications.…”

Effect of Potassium Chloride Fertilization on Two Barley Cultivars Differing in Common Root Rot Reaction

“…The number of diseases which have been reduced in severity by chloride fertilization is growing and includes: stalk rot of corn (Younts and Musgrave 1958), take-all of wheat (Christensen and Brett 1985), stripe rust of wheat (Russell 1978;Scheyer et al 1986), Fusarium root rot of barley (Garvin et al 1981), Fusarium yellows of celery (Schneider 1985), tan spot of wheat (Fixen (Fixen et al 1986), spot blotch of barley (Timm et al 1986), and spot-form net blotch of barley (Dr. A. T. Wright, Research Station, Melfort, Sask. pers.…”
