Abstract

In order to evaluate the allelopathic effects of CANOLA extract and stubble on GERMINATION and growth of CORN and SOYBEAN seedlings, three experiments were conducted using a factorial arrangement in a randomised compelete block design with four replications in greenhouse and laboratory of college of agriculture, University of Gorgan in 2004. The treatment of one greenhouse experiment consisted of: plant species (corn and SOYBEAN) and the amount of CANOLA stubble (0%, 0.35%, 0.71%) and stubble (w/w) based on percentage of soil dry weight. The second experiment was conducted in laboratory and the third one was conducted in greenhouse. The factors consisted of: plant species (corn and SOYBEAN) and CANOLA concentration (5%, 10%, 15% and control). Increasing the amount of stubble and extract concentration of CANOLA decreased the rate and maximum emergence percentage of CORN and SOYBEAN, but the observed changes were not significant. The results showed that stem height, root length, leaf area, root and shoot dry weight in 5 and 15 days after emergence were not affected with respect to control. But in 10 days after emergence, the increase of CANOLA extract concentration and stubble decreased root length and root dry weight of SOYBEAN, respectively. Also increasing of extract concentration of CANOLA significantly decreased CORN rate and maximum GERMINATION percentage in petri dishes. In general, the results suggest that CANOLA extract and stubble at the levels used in this study do not show significant effect on emergence and early growth of CORN plant.
