To analyse the interaction between crop and weed plants, the authors studied the phenomenon of allelopathy among higher plants. The present paper deals with the effects of root exudates from crop and weed plants on the growth of those plants. Three crops, consisting of barley (Hordeum vulgare L.), white clover (Trifolium repens L.) and lupine (Lupinus luteus L.), and Spergula arvensis L. as a weed were grown in sand culture in poly buckets (donor plants). Exudates flowing through a hole in the bottom of each bucket were collected and applied to pots containing the three crops and the weed species also grown on sand (receiver plants). The experiments were conducted with two replications for two years, in 1981 and 1982. Plant height, number of leaves and dry weight of receiver plants were determined when the plants were four months old. The root exudates from all the donor plants inhibited the growth of the receiver plants (Table 1). Number of tillers in barley was decreased by the root exudates from lupine, white clover and Spergula arvensis L. (Table 2). The root exudates from barley reduced the dry weight of the receiver plants except for barley (Fig. 3). Dry weight of all the reciver plants was reduced significantly by treatment of the root exudates from lupine and white clover (Fig. 3). From the results obtained it is suggested that the root exudates from the crops and weed used in this experiment contained growth inhibitors, affecting other plants.
