Effect of silicon application on water use efficiency of alfalfa plants

摘要：

As one of the most important forage crops, alfalfa production is confined by rising irrigation costs and water demand.One tool to imrove sustainability of water use is to increase water use efficiency (WUE) in alfalfa production.Silicon has been found to increase WUE in sunflower by reducing leaf transpiration (Zou et al.2005).Silicon also can increase alfalfa shoot and root growth (Guo et al.2006).If the WUE of alfalfa could be enhanced by a simple agronomic means such adding silicate to the soil, this measurement could potentially be applied in pasture management.
