Abstract
Plants need a variety of elements for their survival in addition to carbon, hydrogen and oxygen which are the main elements in carbohydrates, fats and proteins. These are in generally referred to as mineral elements. [1] Plant nutrients are contained in many agricultural products as they affect the plant growth in a positive way. As I wanted to observe the effect of the volume of the plant nutrients, I used the plant nutrient Anadolu which contains these essential mineral elements, I decided to investigate the effects of the volume of the plant nutrient on the plant growth and I formed a research question. My research question is “How does the volume of the plant nutrient affect the number of leaves and flowers and the length of stem in Pelargonium as an indication of the rate of plant growth?” I conducted an experiment to observe its effects. I formed five groups which contain three plants and gave water to them which have different concentrations of the plant nutrient. In the experiment, the volumes of the plant nutrient which were added to the water given to the plants were measured by the measuring cylinder. 0, 1.7, 3.4, 5.1 and 6.8 ml of the plant nutrient were added to the each of the flowerpots for groups 1, 2, 3, 4 and 5 respectively. They were given 94 ml of water once every three days. The number of leaves and flowers were counted once every three weeks and these measurements were recorded. The results of the experiment supported my hypothesis. There is a statistically significant difference in the number of leaves and flowers when different concentrations of plant nutrient were added to the water which was given to the plants. There is no significant difference in the stem lengths.
