Description
Experiments were carried out in Lithuania over the period 1990- 1995. They involved white clover (Trifolium repens L.) cultivars Atoliai (large - leaved) and Bitunai (intermediate - leaved). Different defoliation treatments were carried out at a height of 5, 10 and 15 cm every week over the period from 7 May to 18 June. On 21-28 May, two more treatments consisting of an application with 0.5 and 1.0 l ha-1 reglone were added. When defoliation was carried out on 11-18 June, the seed of cv. Bitunai and cv. Atoliai matured 7 d and 13 d later, respectively than the seed of the non defoliated stand. A delayed defoliation tended to reduce the weed incidence, lodging and stem height, however, the number of seed-bearing heads, was reduced except in cv. Atoliai. The development of white clover before defoliation does not determine the amount of the seed yield of the aftermath. It is more dependent on the weather conditions during flowering - harvesting time.
