4. Giving Mixed Fertilizer (50 g/seedbed) Treatment : Control Viusid Agro 100% Mixed Fertilizer 75% Mixed Fertilizer Mixed fertilizers were applied by dissolving the fertilizers into water and watered onto seedbeds. Fertilization at 7, 10, 15, 21, 25 and 30 days sowing

6. Resetting (seedbeds to tray transmission) One day before trasmission, tray was sprayed with Viusid Agro (1.5 ml/ 5 L water)

The treatment of Viusid Agro had standard deviation value less than control, so the Viusid Agro treatment has a more uniform the number of leaves compared to the control. Analysis use MINITAB16

Treatment of Viusid Agro had diameter stem bigger than control so that seedlings are more resistant to wind attacks. The treatment of Viusid Agro had the same high seedling and the number of leaves as control. Analysis use MINITAB16

Treatment of Viusid Agro had root deeper than control so the crop nutrient absorption to be better compared to the control Analysis use MINITAB16

CONCLUSION

1) Seedlings of Viusid Agro treatment shown high seedlings, leaves size, number of leaves and volume root the same as control. 2) Seedlings of Viusid Agro treatment had larger diameter stem than control, which indicate better resistance from wind attacks. 3) Seedlings of Viusid Agro treatment shown longer root than control hence the nutrient absorption is better compared to the control.
