Farmers often use fertilizers to improve their crops but do fertilizers really make difference?

Farmers often use fertilizers to improve their crops. For our year 10 coursework we have to find if the fertilizers actually make a difference. To aid us in compleating this task we have been given the following pieces of equipment: - 10 Marrow Seeds

5 Plastic Cups

Compost

Water

Liquid Fertilizer

Weighing Scales

Measuring Cylinder

Because the question asks if fertilizers make a difference, I need to have a control pot, with just marrow seeds and water in. In the other cups I will have different amounts of liquid fertilizer in them. Because I have 10 marrow seeds, I will put 2 marrow seeds into each cup: - meaning that I can have 5 cups, one of which will be a control - leaving me with 4 cups to alter the variable in. In this experiment the variable is the amount of fertilizer, because the question asks if fertilizers make a difference. These are my first thoughts on the amount of liquid fertilizer in each cup.
