Investigations were made to find out the effect of seaweed liquid fertilizers (SLF) obtained from the seaweeds such as Ulva lactuca, Caulerpa scalpelliformis, Padina tetrastromatica and Sargassum linearifolium. Different concentrations of SLF were prepared 5% and 10% from the 100% seaweed extracts. The treated plants were analysed to know the effect of SLF on morphological and biochemical characters. SLF of P.tetrastromatica at 10% concentration showed better result for root length, shoot length and leaf surface area. The amounts of proteins were found to be more when the plants received 10% SLF of P. tetrastromatica and S. linearifolium. Similarly the amino acid contents were also more in Brassica nigra treated with 10% SLF of P. tetrastromatica and S. linearifolium. But it showed poor response to the SLF of U. lactuca. The results of sugar contents indicated that the SLF of C. scalpelliformis were more effective than the others.
