The Effects of Fertilizer on Plant Growth | Science Fair Projects | STEM Projects
Do you want to know how fertilizer affects the growth of plants? Conduct an experiment with radish plants and different concentrations of fertilizer to find out! Measure the average height of the plants after 10 days to see which concentration of fertilizer had the most effect.

Hypothesis

The hypothesis is that watering a plant with too little or too much fertilizer will slow down its growth.

Method & Materials

You will divide 15 pots into 5 groups with 3 plants in each group. Each group will be watered with a different concentration of fertilizer. Measure the average height of the plants after 10 days to see which concentration of fertilizer had the most effect.
You will need 1 packet of radish seeds, 15 plastic pots, soil, Hasta Gro fertilizer, tap water, a ruler, 5 plastic containers, and a measuring cup.

Results

The results showed that the plants in group C, which were watered with the recommended concentration of fertilizer, had the fastest growth in 10 days. The plants in groups A and E, which were watered with too little or too much fertilizer, had the slowest growth in the 10 days.

Why do this project?

This science project is interesting because it shows how important it is to use the correct amount of fertilizer when watering plants. Too little or too much fertilizer can have a negative effect on the growth of the plants.

Also Consider

Variations of this science project could include using different types of plants, such as bamboo or beans, or using different brands of fertilizer.
