Description
Rhizoma peanut is the common name given species in section Rhizomatosae of the genus Arachis. Florigraze rhizoma peanut (A. glabrata Benth.) has been released as a cultivar by the Florida agricultural experiment stations and the USDA Soil Conservation Service. Florigraze is adapted to the well-drained soils of Florida and the warm humid tropics and subtropics around the world. Rhizoma peanuts are propagated by rhizomes, which in Florida are best planted during winter. The slowness of coverage during early establishment is the biggest shortcoming of rhizoma peanuts. If they are established first, rhizoma peanuts will grow well in mixture with bermudagrass (Cynodon dactylon [L.] Pers.), digitgrass (Digitaria decumbens Stent.), and bahiagrass (Paspalum notatum Flugge). Average seasonal yield of Florigraze grown in mixture with a sparse stand of Pensacola bahiagrass over five seasons was 10.5 metric tons (mt)/ha. Bahiagrass without peanut yielded only 2 to 3 mt/ha annually. Pure Florigraze peanut cut at hay stage normally has a protein content of 14% to 16% and in-vitro organic-matter digestibility (IVOMD) above 60%. Florigraze cut every 2 weeks had an annual dry-matter yield of 5 mt/ha, 22% protein, 74% IVOMD, and 93% leaf in forage. Over 2 seasons the dry-matter yield (10 mt/ha) was similar at 6-, 8-, 10-, and 12-week cutting intervals. Protein, IVOMD, and leaf percentages of Florigraze rhizoma peanut progressively decreased as length of cutting interval increased from 2 to 12 weeks. Rhizoma peanuts can be used for pasture, hay, greenchop, high-quality dehydrated hay and leaf meal, creep graz• ing, ornamental ground cover, and possibly as a living mulch in which other crops and trees can be planted. Weeds are the biggest pest problem with rhizoma peanuts, especially during establishment. So far, there have been no serious insect, disease, or nematode problems reported with rhizoma peanuts in Florida.
