Description
The objective of the experiment was to identify traits associated with the production of plant biomass, and hence with P utilization efficiency, when legume species were fertilized. Red clover (Trifolium pratense) and narrowleaf birdsfoot trefoil (Lotus tenuis) were compared in a greenhouse experiment using phosphorus deficient soils. Three plants grew in pots fertilized with 0, 2, 4, 8, 15, 20, 30 and 40 ppm in soil, in a randomized experimental design. Harvest was made at 60 days from the sowing date. Leaf areas, shoot and root biomass, and tissue phosphorus contents were measured. Results showed that changes in leaf area ratio in response to phosphorus fertilization influence nutrient use efficiency. Lotus tenuis showed a pronounced decreasing trend in these variables compared with Trifolium pratense (P< 0.05).
