Soybeans: There is growing evidence that a few varieties of soybeans, growing under certain conditions. benefit from bee pollination. Otherwise they are selfpollinating.
Sunflowers: The acreage of sunflowers is rapidly increasing in Ohio as the demand for seed and oil increases. Insect pollination is essential for a fully filled head. Frequently, the center of the head is filled with unfertilized ovules when bee populations are low and pollen is not moved from flower head to flower head. Bees should be supplied at a rate of at least 1 colony per acre, until research sheds more light on the subject.
