Effects of seaweed extract on growth and biochemical parameters of black gram

Marine algae are one of the renewable and economically valuable sea wealth. Different forms of seaweed preparations such as seaweed liquid fertilizer (SLF) also known as liquid seaweed fertilizer (LSF) have been used as bio-fertilizers and reported to produce beneficial effects on pulses and cereals. The present study deals with the effect of seaweed extract prepared from Gracilaria corticala on seedling growth and biochemical parameters of Vigna mungo L. (Black gram). SLF at 20 percent concentration increased the morphological parameters like length of shoot and root and fresh and dry weight of shoot and root, the pigment and protein content. The other concentrations showed declining trend.
