When kharif maize-wheat cropping system is followed the population of cyperus rotundus in maize decreases significantly. Is this due to allelopathic effct of wheat crop????
Well, wheat crop may have only trivial effect as for as allelopathy is concerned.The effect on reduced Cyprus population might be due to persistence of various herbicide used in wheat crop for various grass and broad leaf weeds such as sulphonylurea ureas (metsulfouron,sulfosulfuron and many more products like Atlantis).
