Open field pollination

Pollination plays a pivotal role in the formation of fruits and seeds. In the context of open field crop cultivation, effective pollination is key to bountiful [...] honeybees. This abundance of pollen proves instrumental in promoting robust pollination and contributes to the development of more uniform and larger fruits [...] environments, bees are among the most efficient and reliable pollinators. Their foraging activities enable the cross-pollination of plants, increasing genetic
