The effect of vitamin D on plant growthFeatured science projectScience project video

Conclusion

The hypothesis that  higher concentrations of vitamin D  help make  plants grow more quickly, has been proven to be true.

Plants normally obtain the vitamins and nutrients that they require to grow, from the soil and their surrounding environment. Fertilizers are normally added when the nutrients become lacking in the soil. Adding  fertilizers definitely helps to improve the growth and health of plants.

Also consider

The science fair project can be repeated with different vitamins like vitamin C and vitamin B.

Try to repeat the science project experiment using minerals like iron, phosphorous, zinc and calcium.
