During the reproductive stage, what management focus is recommended?

• A. Harvest scheduling.
• B. Increase soil salinity.
• C. Allow high humidity at all times.
• D. Control heat and humidity.

Answer: (D)

During the reproductive stage, plants are highly sensitive to environmental stress, so the focus is on creating a stable, favorable climate for flowering, pollination, and fruit or seed set. Controlling heat and humidity directly reduces two major stressors: heat can cause pollen sterility and flower drop, while excessive or fluctuating humidity promotes disease and can disrupt pollination. By managing temperature and humidity—using ventilation, cooling, shading, and dehumidification—you help ensure flowers develop properly and yields are optimized. Harvest scheduling, soil salinity, or letting humidity run high all the time don’t support reproductive success, so they’re not the right emphasis.
