From teh study we found that organic fertilizer of Tithonia diversifolia (3,25 ton ha-1) + azolla pinnata (3,25 ton ha-1) gave the best effect on plant growth. While the treatment of organic fertilizer of Tithonia diversifolia (2,5 ton ha-1)+ organik fertlizer of Azolla pinnata (2,5 ton ha-1) gave the best effect on yield per plot and weight of 1000 grain.
