Abstract:

A pot experiment was conducted to study the effect of extension of irrigation interval (2, 5, and 10 days) on growth, yield and metabolic changes in mungbean (Vigna radiata L.) var. VC 1000 in addition to potassiomag application. Generally, fresh, dry weights and yield were significantly reduced under water stress treatments. Treatment with K biofertilizer to some extent mitigated the effect of drought stress. The greatest vegetative growth was obtained for plants irrigated every two days and treated with potassiomag, while the greatest seed yield was obtained for plants irrigated every five days and treated with potassiomag. Osmoprotectants such as total soluble sugars, proline and glycine betaine increased in plants subjected to water stress. It could be concluded, that to maximize mungbean yield, irrigation should be extended through all phenological stages, specially the flowering and the pod-filling stages.
