Incorporating allelopathy into agricultural management may reduce the use of herbicides, cause less pollution, and diminish autotoxic hazards. Authentic inibitors isolated from plant material have been subjects for examination in vitro, but attempts to compare their effects in soils are limited. Soils contain a heterogeneous collection of organic matter of various origins. Organic solvents and water extracts prepared from monoculture wheat soils under conventionai tilage (CT) and no tilage (NT) indicated tht both soils contain some inhibittory compounds. The CGC/MS/DA of some of the organics is presented. Selected organics from CT and NT as well as allelopathic and autotoxic effects are described and discussed. The relationship between the wheat yields in CT and NT and the possible biological stress is indicated. |
