Abstract:
Panicum antidotale Retz besides reducing its own growth retarded the growth of Pennisetum americanum in mixed root cultures. Cold water extracts from inflorescences shoots and roots, root exudates and soil underneath it not only inhibited its own germination and growth but also that of Brassica campestris, Cenchrus ciliaris, Lolium multifloyum, Pennisetum americanum,. Setaria italica and Sorghum almum in laboratory bioassay. Shoot extract in addition to causing deaths of Pennisetum americanum and Setaria italica, reduced fresh and dry biomass of the seedlings. Toxicity depended upon the part assayed, test species used and physiological process involved. The grass would not exhibit its benefits as range grass either mono-or in mixed cultures with the above-mentioned grasses due to allelopathy.
