Study on using corn cob for marigold seedling germination was conducted by soaking corn cob in water and in different fertilizer solutions for 3 and 7 days. There were 2 experiments in a Completely Randomized Design, six treatments and four replications. In the first experiment, germination percentages, seedling heights and seedling root lengths were not significantly different in the treatments which were soaked in water and a solution made by dissolving 2 or 4 gm of 16-20-0 or 15-15-15 in 10 litres of water. Furthermore, seedling at 15-20 days showed stunt symptoms, due to a lack of plant nutrients. Meanwhile, the use of greater fertilizer concentrations in the second experiment showed significant results. Solutions of 10 and 15 gm of 16-20-0 or 15-15-15 in 10 litres of water gave higher germination percentages, seedling heights and seedling root lengths, when compared to the treatments of water and cow manure solutions. The seedling growth rate of marigold treated by fertilizer solution was very good because of having sufficient essential nutrient.
