Abstract
The purpose of this experiment is to determine how various commercial fertilizers impact and affect the growth of different grass species. The types of Cynodon dactylon that were used are as follows: Bermuda Grass, Rye Grass, and Smart Blend. The types of fertilizers that were used are as follows: Sta-Green Lawn Food, Sta-Green Starter Fertilizer, and Shake ‘n’ Feed. The hypothesis for this project is that Sta-Green Starter fertilizer will cause Rye grass to grow better than all other mixtures or control groups. The null hypothesis is that no other tested fertilizer or seed combination will impact the growth of the grass. The growth was judged by how healthy the grass looked while growing and the height of the grass. Statistical analysis was conducted after the data was collected shows that there is a statistically significant difference in the mixture of grass seed and fertilizer. The analysis disproved the hypothesis and the Smart Blend grass seed by itself grew the tallest and thickest as evidenced by the difference in the groups by seeing how the F value in the ANOVA test was much greater than the F-crit value.
