Effect Of Seaweed Liquid Fertilizer On Growth, Pigment Concentration And Yield Of Amaranthus Roxburghinus And Amaranthus Tricolor Under Field Trial

The present study an attempt has been made to investigate the effect of Seaweed Liquid Fertilizer (SLF) of Ulva lactuca without chemical fertilizer on growth, pigment content and yield of Amaranthus roxburghinus and Amaranthus tricolor (greens) was analyzed. Among the different concentrations of SLF(s) investigated, the A. roxburghinus that received with 1.5 % SLF showed maximum fresh weight, dry weight, root and shoot length, leaf area and content of total chlorophyll, chlorophyll a and b, protein, carbohydrate, lipid and yield whereas, in A. tricolor maximum at 1.0% level. The SLF was also analyzed for micro and macro elements and the plant growth regulators like Auxin and Cytokinin.
