QuestionAgriculture / hedgerows
Farmers surround the fields with hedgerows during high insolation period to:
- (a) prevent the reduction in photosynthetic activity.
- (b) reduce evapotranspiration.
- (c) create conditions for plants to close their stomata.
- (d) prevent wilting of plants.
Answer: (a) prevent the reduction in photosynthetic activity.
Hedgerows act as windbreaks and give partial shade. In high insolation, excess light and heat cause stomatal closure and photo-inhibition; hedgerows prevent the fall in photosynthetic activity and also cut moisture loss. Key holds (a).
