Science Fair Project – Effects of Vitamins on Plants
This link discusses the research of scientists in India who soaked pearl millet seeds in various vitamin solutions.
The results indicated that vitamins reduced the incidence of disease.
This would be an excellent science project. Try soaking alfalfa seed or mung bean seed in vitamin water and record the time taken to sprout, the drought resistance or the growth rate of the sprouts.
