Abstract: By the methods of bioassay and pot experiment, this paper studied the allelopathic effects of water extracts, decayed materials’ liquids, and decayed materials themselves of different crop stalks (corn, rice, and soybean) on the growth of pepper. An inhibitory effect of the water extracts of test stalks, esp ecially for that of soybean stalk, was observed on the germination of pepper see ds, and, with increasing concentration of the extracts, the seed germination rat e and the radicle length decreased significantly (P<0.05 or P<0.01). The liquids of the decayed materials of test stalks had an overall stimulation effect on th e seed germination, and the decayed materials of the stalks all had promotion ef fects on the seedling’s height, stem diameter, fresh mass, and root vigor. Th e promotion effect of the decayed materials was in the order of corn stalk > ric e stalk > soybean stalk, and increased with their addition amount.
