  • Effect of Distillation Time on Mentha canadensis Essential Oil Yield and Composition 

    Zheljazkov, Valtcho D., and Tess Astatkie. 2012. "Effect of Distillation Time on Mentha canadensis Essential Oil Yield and Composition." HortScience 47(5): 643-647.
    Japanese cornmint (Mentha canadensis L.) is a major essential oil crop grown in Asia, South America, and to a limited extent in eastern Europe. Japanese cornmint oil is the only commercially viable source for crystalline ...
  • Effect of distillation waste water and plant hormones on spearmint growth and composition 

    Zheljazkov, Valtcho D., and Tess Astatkie. 2011. "Effect of distillation waste water and plant hormones on spearmint growth and composition." Journal of the science of food and agriculture 91(6): 1135-1141.
    BACKGROUND: Distillation waste water (DWW) is a by-product from steam distillation of essential-oil crops; and currently, it is discharged into streams and rivers. The effects of DWW from 13 essential-oil crops, extracts ...

    We evaluated the effects of foliar sprays made of residual distillation waters from 13 species containing essential oil (Melissa officinalis, Mentha arvensis, M. gracilis, M. x piperita, M. spicata, Monarda citriodora, ...
  • The effect of soybean variety on corn-soybean intercrop biomass and protein yields 

    Martin, R. C., T. Astatkie, and J. M. Cooper. 1998. "The effect of soybean variety on corn-soybean intercrop biomass and protein yields." Canadian Journal of Plant Science 78(2): 289-294.
    Soybean intercropped with corn can produce a high-quality silage, but pods of early maturing soybean varieties usually shatter when harvested, thus reducing the silage protein potential. In 1991 and 1992, an experiment was ...
