摘要
Competitive interactions between grasses and clover in mixture are affected by the grass field study to examine how these factors interacted in orchardgrass (Dactylis glomerata L.) and white clover (Trifolium repens L.) mixtures. 'Dawn' and 'Pennlate' orchardgrass were established at several plant densities in mixture with 'Will' white clover. The experiment was conducted on three sites in pennsylvania of different soil type and elevation. Increasing grass plant density significantly reduced grass tillering and increased competition with white clover. Grass and white clover plant structure was affected by plant density and environment.
