Nitrogen and Phosphorus’ Effects in Bonnie Green Bell 

Sean Appleford, Jacob Smithers, and Dr. Ruben Alarcon


Literature concerning the effects of nitrogen and phosphorus on plant growth is extensive and well documented. However, confounding variables may tamper with plant physiology resulting in inaccurate estimates to the effectiveness of nitrogen and phosphorus-based fertilizers. This study seeks to mitigate the effects of such variables with a randomized block design using Capsicum annuum (Bonnie Green Bell) as the tested plant and their corresponding nitrogen/phosphorus fertilizers. In addition to vertical plant growth, other responding variables concerning plant physiology will be recorded as well including: N-P-K (nitrogen, phosphorus, potassium) and pH soil levels, moisture of the soil, and chlorophyll content of leaves. The results that are expected is that nitrogen will have the largest effect on plant growth followed by phosphorus. While both elements are critical, Nitrogen appears to play a major role in the collection and allocation of sunlight when compared to phosphorus. Both treatments are expected to have a result that differs from the control group.
