Honeybees as Vetch Pollinating Agents

Vetch seed production was increased four-fold by using honeybees as pollinating agents in a two-year test conducted by the Oklahoma Agricultural Experiment Station. The test was conducted at the Red Plains Conservation Experiment Station near Guthrie during the 1951 and 1952 seasons. This publication summarizes the results

Some Observations on Pollination of Alfalfa Hay

During the summer of 1948, observations were made on the prevalence of pollinating insects in several alfalfa fields in the vicinity of Stillwater, Oklahoma. In making these observations their abundance was determined by counting the number of pollinating insects that could be collected per sweep with a sweeping net. These collections were made by sweeping the plants, walking through the field at ordinary walking rates. All sweeps were made in front of the person doing the collecting. The sweepings were made in different fields at various times and as a rule about the time that the alfalfa plants were beginning to blossom. It was not possible to make the sweepings throughout the blossoming period because the crop would be cut for hay about the time the plants came into full blossom. The 1948 season in the vicinity of Stillwater was not a good season for alfalfa seed production. While data for comparison are not available, it is, however, believed that the plants did not blossom as profusely as is normal for this vicinity. As a rule, the third crop is used in seed production, and that crop did not produce an average seed yield during the summer of 1948. In addition to the poor showing there was also a serious outbreak of blister beetles and webworms

Honey Bees and Vetch Pollination

Pollination studies in Oklahoma have been underway for several years, but most of the effort has been directed toward the production of alfalfa seed. During the 1951 season, we also made some preliminary tests to determine the effect of honey bees on the production of vetch seed. These observations were made at the Red Plains Experiment Station near Guthrie, Oklahoma. The field of vetch at this station consisted of about sixty acres. Mr. Harley Daniels, the superintendent of the station, made arrangements with Mr. Lyman Coe, Entomologist of the Samuel Roberts Noble Foundation, Ardmore, Oklahoma, to supply the bees for pollination of this field. The bees were moved into the field early in June at about the time the vetch was coming into full bloom. There was an average of two colonies per acre. The hives were distributed over the fields in groups of 15 to 20 colonies per location, so that if the bees from the various groups ranged in a radius of one-fourth mile from their home location, their activities would easily overlap. The heaviest concentration of bees was perhaps toward the south end of the field. Since the prevailing wind was from the southwest, it gave this group of bees the advantage of drifting with the wind over the main portion of the field
