Growth Responses of Marama Bean (Tylosema esculentum) to Water Deficit Conditions

I.S. Travlos and A.J. Karamanos

Abstract: This study was undertaken in order to evaluate the influences of several water supply regimes on marama growth parameters. Therefore, glasshouse-grown marama plants were subjected to several water treatments by applying different irrigation doses. Measurements of several growth parameters were taken during all the experimental period. Vegetative growth of the more intense water-stressed plants was significantly restricted, while there was a 31-66% reduction of total dry matter production compared to the plants of the rest three water treatments. Irrigation clearly promoted greater biomass allocation to the shoot and leaves and thereby increased the above ground: Below ground dry matter ratio. In conclusion, this study revealed the beneficial effect of an adequate water supply on growth and dry matter production of marama, which seems not to be drought tolerant-as long as it cannot grow well without a good water supply but a rather drought avoiding species, using its tubers as water reservoirs.
