Salinity in the root zone affects crop growth

Plain text source: 
Figure 1 Growth of wheat plants treated with Hoag land nutrient solutions of varying salinity.. Experiments in our project have shown that transient salinity - accumulation of salt in root zone layers not influenced by the watertable - affects crop yield and growth in dryland regions, mainly by reducing water-use efficiency of crops through osmotic effect... Hoagland solution was used to reduce the specific ion toxicity to a minimal level and find out the effects of osmotic pressure, irrespective of the type of salt...
