Persian clover flowers "Ira - Ba 2/79" are visited in great number by honey bees which collect nectar and pollen throughout the whole day. The greatest density of foraging honey bees on the overgrowth average amounts about 15 foragers on 1 sq. m. Five colonies of honey bees per hectar are sufficient for good pollination of flowers and collection of flow. One flower secretes 0.07-0.13 mg of sugars, average about 0.10 mg, with concentration of them in nectar 20-70 percent. Sugar efficiency from 1 ha oscillates within the limits 130-240 kg.
