Heavy nitrogen fertilizer applications on plants may cause which effect?

• A. Make the plant more cold resistant if applied in late august
• B. Increase vegetative growth at the expense of flowering
• C. Refuse lush vegetative growth
• D. Improve disease resistance when applied in late summer

Answer: (B)

Heavy nitrogen fuels vegetative growth. When plants have plenty of nitrogen, they focus on producing more leaves and new shoots because nitrogen supports amino acids, proteins, and chlorophyll. That shift in resource use means more green, leafy growth and less energy allocated to developing flowers or fruits, so flowering diminishes as vegetative growth increases. The other outcomes aren’t typical results of heavy nitrogen—nitrogen doesn’t inherently boost cold hardiness or disease resistance, and while it won’t cause plants to refuse growth, it often promotes lush foliage instead of blooms.
