Synergistic Effect of Seaweed Extract and Urea Fertilizer on Growth and Biochemical Parameters of Triticum aestivum at Vegetative Stage

This study was designed in order to investigate the Synergistic effect of seaweed extract (Nizamuddinia zanardinii) and urea fertilizer on growth and biochemical parameters of Triticum aestivum at vegetative stage. Experiment was factorial with completely randomized design, with three replication at five levels (0, 5, 10, 15 and 20 percent) of brown seaweed extract and three levels of urea (0, 25 and 50 percent of recommended amount). According to the results, maximum dry weight of leaf, shoot and root (0/85, 0/87 and 0/09 g), shoot and root length (46/67 and 13/5 cm), content of total chlorophyll and carotenoid (0/73 and 0/16 mgg-1fr.wt), activity of peroxidase and ascorbateperoxidase enzyme (8/6 and 0/82 ΔOD.min-1/mg.protein) was observed at 10% concentration of brown seaweed extract with 25% recommended rate of urea fertilizer. The maximum amount of malondialdehyde (19/42 mM/g.FW) and Catalase activity (0/64 ΔOD.min-1/mg.protein) was observed in 20% concentration of brown seaweed
