Global warming has recently become one of the biggest threats that the world faces. The importance of fertile lands and water sources are constantly increasing. Many researches are done to get more qualified crops and different solutions are found. Fertilizers are one of those solutions. Ammonium nitrate (AN) is a type of chemical fertilizers and it increases the rate of the growth of the plants. Different masses of AN cause different effects on plants. Therefore, it must be given in an optimum ratio. The objective of this study is to investigate whether different masses of AN fertilizer used is effective on the growth of the Phaseolus vulgaris. During the experiment, proportionally increasing masses of AN is mixed to the soil that common beans are planted in. Four groups are developed; control group containing no fertilizer, experimental group 1 containing 0.42 g AN, experimental group 2 containing 0.84 g AN and the last group, experimental group 3 containing 1.26 g AN. The plants are irrigated daily and observed for 1.5 months in order to see the effects of different masses of AN by taking measurements of the stem length, number of offsprings produced and observing the color of leaves. The results showed that there comes a significant difference if the mass of fertilizer used is changed. As the mass of AN used increases, the growth rate increases; however the excess mass of AN causes deficiency in some essential elements for the plant and reduces root growth.
