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

Abstract

This science fair project was done to observe the effectiveness of vitamin D on the growth of plants. The science project involved watering radish, green bean and chili plants with different concentrations of vitamin D solution.

Hypothesis

A higher concentration of vitamin D will help plants grow more quickly.

Scientific Terms

Vitamin C, vitamin D2, vitamin D3, organic compound, nutrients, immunity, diseases, photosynthesis

Background

Vitamins and plant growth

Vitamins are important for plant growth. Vitamins are made up of organic compounds and help plants to grow by providing them with essential nutrients. Vitamins also help plants to improve their immunity against plant diseases. The type of vitamins required to enhance growth will depend on the type of plant.

Vitamin C or ascorbic acid helps to maximize the growth of plants. Plants actually require vitamin C for them to mature. Vitamin C also helps plants with the process of photosynthesis. It also helps provide the plants with protection from ultraviolet rays, and helps the plants cope with climate changes. Interestingly, it also helps reduce plant stress!

Vitamins D2 and D3 also help to enhance plant growth. Vitamin D3 helps plants to absorb calcium into the stems. It is also very useful in plants that are pruned (grown by cutting their stems to allowing the roots to grow). Vitamin D is important is helping the plant grow roots under stressful conditions.
