Seeds of forage legume esparcet of Kazakhstan have a local seed size and high allelopathic activity

Description

[Synopsis]

Esparcet (Onobrychis spp.) is cultivated in Central Asia and is an important legume for soil fertilization and for feeding. We evaluated the germination and allelopathic activity of the esparcet seed produced in Kazakhstan. An individual plant of esparcet has many seeds, but one seed is in one pod. These seeds have a local morphology including seed size. The germination of esparcet seed without pod was faster than that of seed within the pod. In checking allelopathic effect using the sandwich method (Fujii and Shibuya, 1991), allelopathic activity of seed without pod was much higher than those of seed with pod and only pod. These results will help us in establishing a technology of esparcet in connection with weed control using the allelopathy.
