Proximate and elemental composition of four peanut genotypes infected with groundnut rosette disease ( GRD ) was examined. Moisture and ash content generally decreased while fat and energy content increased in seeds from diseased plants. Protein and carbohydrate varied between seeds of diseased and healthy plants of the different varieties with no consistent pattern. Instrumental neutron activation analysis of 10 elements within leaves, stems and seeds showed elevated levels of K, Al and Cl in leaves, stems and seeds in at least three of the four varieties infected with GRD while Na was decreased in stems but increased in seeds. While significant differences were found, Mg, Mn, Ca and Zn did not show any consistent change with respect to plant part or genotype, between diseased and healthy plants. V and Fe were found at low levels in leaves and stems and not detected in seeds. This represents the first report on the effect of GRD on the nutritive quality of peanuts.
