abstract: An investigation was conducted to study the effects of cultural practices and host-plant resistance on rosette
disease incidence and pod yields of elite groundnut genotypes during four growing seasons in Malawi. The
effects of genotypes and cultural practices, and their interactions on rosette disease incidence were significant
at pegging stage under high disease pressure in all seasons. The genotypic differences in disease incidence
were spectacular under high disease infestation in all seasons. Resistant genotypes gave higher pod yields
than susceptible genotypes under high disease incidence, irrespective of sowing time and plant population.
However, pod yields were higher for early sown treatments at optimum plant population. There were no
marked differences in pod yield between genotypes under low disease pressure. Overall, the combination of
resistant genotypes with early sowing at optimum plant population exhibited the best performance under high
disease infestation. Although the resistant genotypes gave the highest pod yields under high disease
infestation, pod yields were consistently lower than the yields under low disease situation probably because of
their susceptibility to groundnut rosette assistor virus (GRAV) component.
