Botanical Composition Improvement with Subterranean Clover (Trifolium subterraneum L.) in Grass Mixtures

Viliana Vasileva

Abstract:
Botanical composition of cocksfoot and tall fescue, pure and in mixtures with three subspecies subterranean clover were investigated in field trial in the Institute of Forage Crops, Pleven, Bulgaria (2011-2013). The next ratios were used: Grass+Trifolium subterraneum ssp. brachycalicinum (50:50%), Grass+Trifolium subterraneum ssp. yaninicum (50:50%), Grass+Trifolium subterraneum ssp. subterraneum (50:50%), Grass+Trifolium subterraneum ssp. brachycalicinum+Trifolium subterraneum ssp. yaninicum+Trifolium subterraneum ssp. subterraneum (25:25:25:25%). It was found that inclusion the subterranean clover as a component of mixtures with cocksfoot and tall fescue had positive effect on the botanical composition and decreased the weed infestation in the swards. Trifolium subterraneum ssp. brachycalicinum in mixture with cocksfoot had faster growing rate as well the biggest part in the sward (31.0%) and reduced the weeds half. Trifolium subterraneum ssp. brachycalicinum in mixtures with tall fescue had small part and decreased the weeds by 28.1%. Subterranean clover as a legume component contributed to increasing the leaf/stem ratio of cocksfoot and tall fescue.
