Experiment was conducted with five mungbean genotypes with the aim of ascertaining the effects of salt stress on the yield and its component. The decrease in seed yield per plant under salt stress was more pronounced associated with a reduced number of seed per pod and 100 seed weight. Consequently salt stress was more effective at vegetative, flowering and seed filling stages rather than seed development stage in all the five genotypes. NM-92 was less affected which showed its adaptability under saline conditions. Delayed maturity due to salt stress pushes the plant also be desiccation stress causing shriveled seeds.
