Agronomy Abstracts. p. 88. Interpretive Summary: Technical Abstract: The initial success of each species within multi-species plantings depends on interactions between the inherent vigor of individual seedlings and the competitive ability of neighboring plants. Competitive ability, in turn, can be influenced by spatial and temporal relationships among individuals. Four forage species, perennial ryegrass, orchardgrass, white clover, and birdsfoot trefoil were planted in monocultures and in mixtures at two population densities and at two sites differing in soil water-holding capacity. The locations and times of emergence for all individuals within a 25 x 25 cm grid were recorded and each plant was harvested separately. The influence of these spatial and temporal relationships, along with the effects of drought stress on seedling emergence, growth, and mortality will be discussed. |
