Algal exopolysaccharide with Magnesium chloride was applied as nutrient for wheat plant. Exopolysaccharide addition of 0.5-1 wt% showed enhancement in the amino acid content, Chlorophyll content and relative water content in wheat plant. Based on the present study it can be concluded that combination of EPS and MgCl2 can be recommend as bio-stimulant to enhancing the photosynthetic activity in commercial crops. Exopolysaccharide from Porphyridium has a great potential and can be used as bio-stimulator for agriculture application. Copyright@ International Science Community Association
