Description
Trifolium alexandrinum is believed to be originated in Palestine. It thrives when the temperature is between 0° and 35°C and is used in frost free regions. Berseem clover makes its best growth on well-drained soils, but is susceptible to salinity. Berseem clover is an annual legume. It has an erect stem and reaches a height of about 75 cm. The tap-root may penetrate the soil to a depth of 40 to 60 cm. The leaves are tlifoliate. The flowers are composed panicle, the seeds vary in color from yellow to green, gradually turning red to brown. Pollination takes place by the tripping action of insects. Berseem clover has been grown in northern a,nd southern part of Iran since many years, especially in Mazandaran, Gilan and Khozistan plivinces. Rice growers use this clover in their crop rotation, on more than 40,000 ha at the present time. Within the next ten years, this surface will increase up to 250,000 ha. After rice, cultivation is devoted to Bersccm clover. It is sown after rice is harvested. One of the most important problems in growing Bcrseem clover is to improve its seed deficiency. About 1,700 tons of seed are imported so far, and it is estimated that about 11,000 tons of seed would be needed for next ten years. The results of consecutive 3-year experiment revealed that in Karaj the best sowing date for Berseem clover is early spring, and if a correct management is applied, we would be able to produce 1 ton of seed per ha.
