Row spacing is an important management strategy in white clover (Trifolium repens) seed crops. Stolons grow outward from the crown of the plant into the space between rows. Nodes produced along the stolon bear either vegetative axillary growth (e.g. a branch) or a reproductive leaf-flower combination. The more nodes that are produced per stolon, and subsequently per unit area, the greater opportunity for flower production and thereby seed yield. In theory, wider row spacing should produce more flowers/m2 due to more space for stolon proliferation.
