Earlier research indicated that orchardgrass (Dactylis glomerata L.) cultivars affected white clover (Trifolium repens L.) stolon structure during establishment. We conducted a field study to determine if plant density and environment modified the effect of orchardgrass cultivars on white clover. `Dawn' and `Pennlate' orchardgrasses were established at 10-, 20-, or 40-cm spacings in mixture with `Will' white clover in a systematic plant spacing design. Plots were established in September 1996 on a Hagerstown, Berks, or Rayne soil in central Pennsylvania. Orchardgrass was harvested monthly ...
<0.05), however, indicated that the magnitude of increase differed among sites. Dry matter yield was lowest and increased very little with plant spacing at Kylertown. The Rock Springs and Port Matilda sites did not differ (P><0.05) in the number of main stolons along with first-order branches as spacing between grass plants increased. The highest stolon densities occurred at the 40-cm plant spacing at Rock Springs in 1998, where there was>
