Conteúdo: | The observed delayed emergence and seedling development in wheat (Triticum aestivum L.) planted into soybean (Glycine max [L.] Merr.) residues in the field were reproduced in the greenhouse. Severity of the effects were increased as the rate of residue increased. Residues, and leachates from residues, inhibited wheat growth and reduced yields 19-29% in the field. Shallow incorporation of residues into soil resulted in delayed emergence, thinner stands, and greatly shortened coleoptile lenght. Emergence was reduced more under "moderately dry" soil conditions while studing was more pronounced under "wet" soil conditions. Residues appeared to have no direct effect on Rhizoctonia winter-kill. Based on this research, even distribution of soybean residues across the field at harvest and deep placement of the residue should reduce these allelopathic effects on a subsequent wheat crop.
