Abstract

Four of the 10 two-component mixtures of five mungbean (vigna radiata) varieties exceeded the yield of the component means by 21.70%, while the rest plus the three-component mixture yielded 10% less, though not significantly. One of the mixtures cutiyielded the best yielding by 7%. Deviation of the mixtures' yield performance from their component means was effected by a change in seed number rather than by a change in seed weight. Number of seeds per pod was not appreciably affected when the varieties were grown in mixtures. Marked deviations from the component mean as to height and seed weight occurred when the components used were of wide character differences; the converse held true for disease infection. Inter-varietal mixing would not necessarily perpetuate the highest yielding varieties at pure stand nor lead to the extinction of the most disease susceptible ones. Further studies on intergenotypic competition and epidemiology of Cercospora disease have to be accomplished before subsequent recommendation of mungbean mixtures for the farmer's field production is resorted.
