    Phytotoxic substances associated with the decomposition of sugarcane trash residues. (Final report SRDC Project BS31S)
    (1992) Hurney, AP; Ridge, DR
    Ratooning through trash blankets is generally effective with minor exceptions for certain varieties and in cold or waterlogged soils. Information was required to determine whether these effects are normal reactions of slow ratooning varieties to the cold conditions or poor aeration, or whether there are toxic effects attributable to trash residues, ie allelopathy. The project was a preliminary investigation to assess potential allelopathic effects from trash residues on the growth of sugarcane. It was concentrated mainly on north Queensland soils and varieties due to the high percentage of trash retention in that area. A smaller test program was carried out at Bundaberg to take into account a wider suite of varieties and soils.
