Manure compost is an organic fertilizer made up of manure or natural nitrogen contents, and typically only supplies crops with nitrogen. Synthetic fertilizer is a man-made compound mixture made from inorganic contents and includes various chemical nutrients such as nitrogen, phosphorus, potassium, calcium, and more. Although fertilizer provides crops with more varied nutrients, it has more negative impacts on the environment. In this study, we compared the growth rate, root width, and final height of Raphanus sativus under manure and synthetic fertilizer treatments. I hypothesized that plants grown in the synthetic fertilizer treatment would slightly outperform the compost treatment group but would not observe a significant difference between the groups. Compost resulted in faster height and leaf growth, but no significant difference was found between the treatments for root width and final height. Thus it was determined that compost has a more stimulating effect on Raphanus sativus growth but doesn’t result in overall differences in growth.
