Abstract
To explore biofertilizing efficiency of seaweed liquid extracts of brown alga Sargassum wightii (S. wightii) on growth, biochemical and yield parameters of Cyamopsis tetragonoloba (C. tetragonoloba). Seaweeds were made to coarse powder and stock solution was prepared. Different concentrations such as 0.5%, 1.0%, 1.5%, 2.0%, 2.5% and 5.0% were prepared and given as foliar spray. Seaweed Liquid Extract (SLE) at low concentration (1.5%) exhibited promoting effect on growth and yield parameters. Differential responses in the content of photosynthetic pigments, protein, reducing sugar, ascorbic acid and in the activity of nitrate reductase were also observed in the leaves of SLE treated seedlings when compared to untreated seedlings. Higher concentrations (above 1.5%) of SLE were found to show inhibitory effect. The presence of micro and macro nutrients, vitamins, growth hormones and other constituents in the seaweed extract might be very much useful to the crops but their level should be appropriate to enhance growth and productivity. It may be concluded that liquid seaweed extracts could serve as cost effective eco-friendly product for sustainable agriculture.
