Experiment 3- Effect of different types of fertilizer

                                                             Experiment 3

AIM: To

Investigate the effect of different types of fertilizer on the growth of plants.
.

APPARATUS AND MATERIAL REQUIRED: 

1. 12 identical plants
2. 3 different types of fertilizer
3. Water
4. Soil
5. Pots
6. Tape measure

This photo shows 12 identical plants that are ready to be fertilized.

OBJECTIVES:

1. To determine which type of fertilizer produces the greatest increase in plant growth.
2. To compare the growth of plants fertilized with different types of fertilizer.

PROCEDURE:

• Divide the 12 plants into 4 groups of 3.
• Label each group of plants A, B, C, or D.
• Fertilize the plants in group A with fertilizer A, the plants in group B with fertilizer B, the plants in group C with fertilizer C, and the plants in group D with no fertilizer (control group).
• Water all of the plants regularly.
• Measure the height of each plant every week for 6 weeks.

This photo shows how to label the plant groups A, B, C, or D.

OBSERVATIONS:

The plants in group A, which were fertilized with fertilizer A, grew the tallest. The plants in group B, which were fertilized with fertilizer B, grew slightly taller than the plants in group C, which were fertilized with fertilizer C. The plants in group D, which were not fertilized, grew the shortest.

CONCLUSION:

Fertilizer A produced the greatest increase in plant growth. Fertilizer B produced a slightly smaller increase in plant growth, and fertilizer C produced the smallest increase in plant growth. The control group, which was not fertilized, grew the least.

This photo shows a healthy plant that has been fertilized and watered regularly.

ADDITIONAL INFORMATION:

The results of this experiment suggest that fertilizer can have a significant impact on the growth of plants. The type of fertilizer used can affect the rate of growth, and the amount of fertilizer used can also affect the rate of growth. It is important to follow the directions on the fertilizer label carefully to avoid over-fertilizing your plants. Over-fertilizing can damage the roots of your plants and stunt their growth.
