Scald Symptoms

Scald in alfalfa is caused when standing water covers the soil and direct bright sunlight heats the soil and water.  Plants  in the center plot regrew more slowly than others.  Foliage in the plots with rapid regrowth shaded the soil and were unharmed by stand water and bright sun.  Plants growing without shading the soil suffered from scald.   This is an alfalfa variety evaluation where 5-row plots are 5m long and 1m wide.
