Deficit irrigation from ebb and flow system effective for poinsettia

(American Society for Horticultural Science) Scientists investigated whether regulated deficit irrigation in an ebb and flow system could alleviate the effects of salinity stress on poinsettia. Degree of medium saturation had a more dramatic effect on plant size than did salinity. Analyses showed that regulated deficit irrigation resulting in partial saturation of the growing medium is an effective management option for controlling plant height and crop growth, and it limits the accumulation of ...
