In this study, the effects of fish liquid fertilizer (Fish Hydrosylate) and aqueous extract of green-algae (chactomopha gracilis), from cladophorales order were evaluated on growth properties of tomato. The fish liquid fertilizer obtained from Persian Gulf fish waste contained P2O5 (0.48 %), K2O (0.14 %), Fe (30.60 ppm), Zn (20.50 ppm), and N (2%). The variance analysis of the traits including shoot length, shoot diameter, radicle length, leaf width and chlorophyll content revealed a significant difference among treatments (p<0.01). The mean comparisons of traits using Duncan's multi-domain test indicated that the fish liquid fertilizer treatments with concentrations of 0.001 and 0.0001 had the highest effects on entire traits. The green-algae extract treatments showed positive effects on studied traits and improved tomato performance and growth parameters. Although, the effects of green macroalgae extract (chactomophora gracilis) were less than that those of fish liquid fertilizer.
