Abstract: Use of marine microalgae as fertilizer in crop production has a long tradition in coastal areas all over the world. Marine algae are classified into three types, namely green (Chlorophyceae), brown (Phaeophyceae) and red (Rhodophyceae) algae based on their pigments like Chlorophyll, Carotenoids and Phycobiliproteins. In the present study, an attempt has been made to investigate the effect of seaweed liquid fertilizer (SLF) of two seaweeds. SLFs obtained from the brown seaweed Padina tetrastromatica and green seaweed Ulva lactuca were tested on the important pulse plant, black gram (Vigna mungo). The seven day old seedlings were used for the estimation of chlorophyll a, b, total chlorophyll and carotenoid. The dry weight is more than that in the control at all the concentrations, i.e., 0.25% to 2.0% of Padina SLF, with the highest record in 0.75 % concentration. While enhanced dry weight of these seedlings over the control was recorded at 0.75 and 1.5% concentrations of Ulva SLF. Present investigation indicates that Padina SLF yielded better results than Ulva SLF.
