Midday watering of lawns may lead to:

1. Enhanced growth

2. Water conservation

3. Improved root absorption

4. A loss of water through evaporation

The correct answer is: A loss of water through evaporation

Midday watering of lawns typically leads to a loss of water through evaporation. During the hottest parts of the day, the sun's intensity is at its peak, causing a significant amount of water to evaporate quickly from the surface of the soil and the leaves of the grass. This means that the water applied may not effectively penetrate the soil where it can benefit the roots, and instead, it may simply be lost to the atmosphere. The other options do not account for the fundamental issue of evaporation. Enhanced growth, water conservation, and improved root absorption imply benefits of watering at times that are more suitable for plant uptake, such as early morning or late afternoon, when temperatures are cooler and the water has a better chance of being retained in the soil.
