Popis: Aims: The aim of the study was to evaluate the effect of root exudates from cowpea, groundnut, maize, sorghum and pearl millet genotypes on the germination and attachment of Alectra vogelii. It also aimed to identify functional groups in the powdered root samples that stimulate A. vogelli germination. Study Design: In the laboratory, a Complete Randomised Design (CRD) replicated six times with six treatments; cowpea (IT18, CBC2 and CBC3); groundnuts (Nyanda), maize (PAN 413), sorghum (Landrace) pearl millet (Landrace) and a negative control (distilled water) were used. Place and Duration of Study: Department of Agronomy Laboratory, Midlands State University Gweru, Zimbabwe (19°25’S and 29°50’E), between March 2014 to May 2014. Methodology: To assess the germination and attachment of A. vogelii seeds, three seeds from each genotype were placed on a moistened filter paper in a petri dish with 0,01 g of preconditioned A. vogelii seeds. Identification of functional groups from the powdered root samples of all the crop genotypes using the FT-IR spectroscopy was also done. Results: Significant differences (P
