Abstract
Groundnut (Arachis hypogaea L.) yield has been reported to decrease by more than 50 percent with successive croppings. Filtrates from fresh and decomposed groundnut plant residues were bioassayed for their effects on germination and radicle elongation of four crop species. Results obtained indicated that the inhibitory substance(s) present in the residues is soluble in water; heat treatment or prolonged decomposition seemed to reduce or possibly eliminate the inhibitory activity of the residues. The production of the inhibitor(s) also seemed to follow a cycle and may also be associated with changes in pH of the residue filtrates. Delaying planting of the subsequent crop is suggested as a precaution against poor germination and early growth if plant residues were incorporated or left on the soil surface after harvest.
