Interpretive Summary:

Technical Abstract: Field experiments were conducted during 1994 and 1995 near Columbia, MO, to compare rhizomatous and non-rhizomatous birdsfoot trefoil (Lotus corniculatus L.) for above-ground (stems, leaves, and reproductive structures) and below-ground (crown, roots, nodules, and rhizomes) dry matter (DM) production. Cuttings were started in the greenhouse, then transplanted to the field in a replicated design with clipped and non- clipped treatments. Plants were sampled every 14 d beginning in July for 10 samplings. Total above-ground and below-ground DM differed significantly by morphological types, clipping treatment, and date. Rhizome development became pronounced at the sixth sampling in mid- September, where rhizomes were approximately 2% of below-ground DM. At the 10th sampling, in early November, rhizomes accounted for about 4.5% of below-ground DM. Birdsfoot trefoil without rhizomes had the greatest above-ground DM for both clipping treatments.
