A surprising lack of statistical difference was found for most metrics measured. Similar total yield was found across all fertilizer levels tested for tomato, and for the 100 to 300 pounds nitrogen/acre for peppers, only the 350 pound/acre level had lower total yield. Pepper plant height was stunted by higher nitrogen levels. This lack of differences may indicate that the important factor in nitrogen (and perhaps other nutrients) application is not in how much is applied, but more on how it is applied, especially in conjunction with how the plants are irrigated.
