Abstract: Three experiments had been done at glass houses of Universiti Pertanian Malaysia (UPM), Serdang, Selangor, Malaysia and Universitas Syiah Kuala (USK), Banda Aceh, Provence Aceh, Indonesia. The first experiment showed that application of 45 uM Mn in solution culture affected on accumulation of Mn as much 6 mg g-1 tissue of the plant. The accumulation of Mn retarded the growth of soybean plant, where leaf area reduce (500 cm2 per plant) compare with control treatment (1500 cm2 per plant). However, application of 7.5 uM Mn in nutrients solution is the best resulted in maximum of leaf area (2500 cm2 per plant). Besides, khlorophyll content due to affected by Mn treatment where the application of 52.5 uM Mn reduced the chlorophyll content to 3 ug cm-2 leaf area. While, on the application of 15 uM, the chlorophyll content per cm was in optimum (5 ug cm-2 leaf area) respectively. The second experiment increasing the number of tomato seedling at tsunami soil addition by organic matter (OM) in ratio (1 : 1). While addition of OM increased the number of flower Rosa sinensis under ratio (1 : 1) with optimum level (5 uM) of Mn application.
