“…Increasing N fertility can increase wheat leaf disease pressure (Boquet and Johnson, 1987;Kelley, 1993;Mascagni et al, 1997), but may decrease severity of root disease (Brennan, 1992a;Wall et al, 1994). Phosphorus fertilization has been shown to reduce wheat diseases in leaf (Boquet and Johnson, 1987;Sweeney et al, 2000) and root tissue (Brennan, 1992b).…”

2 Grain sorghum [Sorghum bicolor (L.)], grown on the often infertile claypan soils of the eastern Great Plains, requires attention to soil fertility. Experimental objectives were to determine the effects of phosphorus (P) and potassium (K) fertility levels, N application, and legume residual on grain sorghum production and stalk rot. Following alfalfa and birdsfoot trefoil, first-year sorghum yield was 7 Mg ha −1 and not affected by N fertilizer. In subsequent years, yield increases due to N were less than 20%. Sorghum yield increased at low P and K rates, especially with nitrogen (N) fertilization and was greater following birdsfoot trefoil than following alfalfa. In 1995 when fertilized with N, lodging and stalk rot severity were increased by P and reduced by K. In 1996, stalk rot severity was reduced by K fertilization. Grain sorghum, grown after legume crops, required minimal levels of P and K, especially when N fertilizer was added.

“…Fertility has been shown to affect disease pressure on several crops. Increasing N fertility can increase wheat leaf disease pressure (1,15,20), but may decrease severity of root disease (2,26). Fusarium stalk rot is the most prevalent disease of sorghum grown in Kansas (14).…”

K, Cl, and N Fertilization Affects Grain Sorghum Production and Stalk Rot

et al. 2010

Claypan soils of the eastern Great Plains are often infertile, requiring producers of grain sorghum [Sorghum bicolor (L.)] to be attentive to soil fertility issues for optimum production. The objectives of this study were to determine the effects of K, Cl, and N fertilization and legume residual on grain sorghum production and stalk rot. On average, sorghum was unaffected by differences in legume residual, but yield was increased by 11% and stalk rot severity was reduced by 20% when fertilized with 75 lb K2O/acre. Plant responses to N fertilization were generally greatest when sorghum was also fertilized with Cl, especially in a stressful year evidenced by plant lodging. Nitrogen fertilization without Cl in 1995 resulted in more than 20% lodging, with about 80% of the bottom 10 nodes showing evidence of stalk rot, but the combination of N and Cl fertilization increased yield by about 20% and reduced stalk rot severity by 25%. Potassium is important in improving yield and reducing disease potential, but especially in a stressful year, Cl obtained with common KCl fertilization may complement N fertilization to optimize yields and suppress disease and lodging.
