Interpretive Summaries:
Soil Fertility and Management Investigations in Southeastern Kansas, 1996
Type of legume residue did not affect the yield of subsequent first or second grain sorghum crops. Yield of the third (1996) grain sorghum crop was greater following alfalfa than birdsfoot trefoil when no N was applied, but not different when fertilized with 125 lb N/a. In 1996, greater sorghum yield increases with P and K were obtained when nitrogen (N) also was supplied. Stalk rot severity was greater with P when no K was applied. Adding K or Cl reduced stalk rot severity, but adding both as KCl did not result in a further reduction in visual presence of Fusariumstalk rot. KS-30F
