Effect of Padina tetrastromatica and Cymodocea serrulata using different methods extract on growth and pigments of black gram (Vigna mungo L.)

Abstract

To investigate the growth, percentage of germination, shoot and root length, fresh and dry weight along with photosynthetic pigments (chlorophyll a, b, and total chlorophyll) of Vigna mungo was analyzed by using seaweed (Padina tetrastromatica) SLF and seagrass (Cymodocea serrulata) SGLF extracts of seven days old seedlings. The seaweed and seagrass extracts were prepared by five different methods such as low temperature, boiling, autoclave, alcohol, and alcohol aqueous extracts with different concentration ( 0.5, 1.0, 2.0, 3.0, 4.0, and 5.0%). The results revealed that significant effect showed low temperature, autoclave, and alcohol aqueous methods of seaweed and seagrass extract preparation, the study suggested that field trial to assess the seaweed and seagrass fertilizer can be used as biofertilizer for better cultivation of Vigna mungo.
