Abstract
The permanent climate changes having occurred in the last decade present a serious risk to the agricultural crops. Тhis requires to study new herbaceous forage species having pronounced resistance to unfavorable abiotic factors and good adaptive capacity towards the new conditions. Legumes species that can provide self-sowing and persist continuously in the sward become of practical importance. Subterranean clover (Trifolium subterraneum L.) is an annual drought resistant legume with winter-spring type of development and ability for self-sowing. The studies with subterranean clover during the last years showed that it has practical applicability under the climatic conditions of Bulgaria. When sown at an appropriate time in the autumn, it establishes a uniform stand before the beginning of the permanent cold spell and grows up early in the spring and forms a dense sward. Subterranean clover was found as a suitable component for mixtures with widely used perennial grass and legume forage crops and contributed to weed infestation decreasing, higher productivity and persistence of the pasture systems. In addition, due to the prostrate habit it is strongly tolerant to grazing. The subterranean clover is adaptable to the changing climatic conditions and its use as a natural bio-recourse in the pastures could be a contribution to finding a solution in the field of forage production to mitigate the adverse effects of climatic change.
