The purpose of this research was to determine the effect and economics of soil ph on red clover seed production and root health. The effects of normal and delayed spring herbage removal, and first and second‐year seed crop age (1994 and 1995) were also examined.
) but impact on seed production depends on the species, abundance, and synchrony with bloom.
The production of red clover seed is directly proportional to pollinator activity. Everly (1950) associated reduced native pollinators with decreased seed yields in indiana, and stated that red-clover pollen- collecting honey bees were effective in setting a good crop of seed.

July, 1932 red-clover pollination 5 work has been presented showing the effect of atmospheric and soil-moistureconditions during pollination and setting of seed. Aicher (1) observes that pollination and fertilization take place most rapidly when blossoms are dry and when the atmosphere is both dry and warm.
Red clover is a valuable forage crop, but often copes with unsatisfactory seed yield. Management practices to increase seed yield include fertilization, adequate weed and pest control, the synchronization of flowering through pre-cutting in spring, and the application of plant growth regulators to prevent lodging. Seed yield problems may have variable underlying reasons, such as inadequate.
Without bees, there could be no production of alfalfa seed or red clover seed, as cross- pollination is necessary for seed set in both crops.
Leafcutter bees can also be used to pollinate red clover, especially the single cut types. In areas with a long growing season, the first crop of double-cut red clover is often cut for hay and the second crop is then harvested for seed.
Crimson clover flowers are known to produce an abundance of nectar, attracting all seeds are produced from open pollinated plants, stored in a temperature.
) is an important forage legume grown in many of the temperate regions around the world.

Fewer flowers, and seed production may be inhibited due to inadequate pollination. Red clover seed yields in western oregon typically range from 500 to 1,200 lb/acre. Seed production is dependent on the formation of functional flowers, successful fertilization, and conditions suitable for seed development.
Pollination is a critical factor in the production of red clover. Given the self-incompatibility of flowers, plants rely on cross-pollination for adequate seed set (smith, taylor and bowley, 1985).

21 may 2015 white clover and crimson clover, with their relatively short florets are readily worked by honeybees with nectar being relatively easy to attain.
The red-clover flower is practically self-sterile; that is, the pollen of a flower will not fertilize any other flower on any head of the same plant. Therefore, before fertilization can occur, it is necessary that the pollen be transferred between flowers on different plants.
The second growth for seed are the best means of controlling injurious insects affecting the seed. Introducing hives of honeybees into or near the fields at the time when red clover is in full bloom will increase cross-pollination and consequently increase the yield of seed. A lack of cross-pollination at this time will result in a small yield.
Consistent yields are obtained by introducing colonies of honeybees to the field.
By far the greater seed crop is reported from the first cutting.
) but impact on seed production depends on the species, abundance, and synchrony with bloom. The objectives of the current study were to examine pollination by a native bumble bee, bombus vosnesenskii (radoszkowski), determine the bumble bee fauna associated with red clover in oregon, and assess if seed set is limiting.
16 jul 2018 production of red clover seeds depends on insect pollination for seed set, which is mainly performed by bumble bees (free, 1993).
Red clover should be top dressed annually with fertilizer (using soil testing as a guide for determining fertilizer requirements) as long as the plant numbers are sufficient for economic production. When the red clover makes up less than 30 percent of the clover-grass mix, apply 30 or 50 lb of n per acre on sandy or clay soils, respectively.

Pollination by honey bees was estimated to account for 193 to 456 lb seed/ac out of total yields of 276-540 lb/ac when bees were located adjacent to the fields of medium red clover, while at distances greater than 1 mile from the nearest apiary pollination by honey bees was insignificant.
