Why are beehives kept in crop field during flowering period? Name any two crop fields where this is practiced.

Explanation

Bees, while collecting nectar flowers, transfer the pollen grains. Beehives are kept in a crop fild during flowering period to enhance the pollination of the crop, which increases the crop yield. Also, bees can easily collect huge amounts of nectar from the flowers of the crop in a close reach without much foraging. This increase honey production. This technique is practised in apple and watermelon fields.
