Recommended planting season for rhizoma peanut (RP; Arachis glabrata Benth.) is January through March. Land area planted to RP annually has increased, requiring custom planters to extend planting beyond that period, and variation in rhizome quality and establishment success have been reported. The objectives of this study were to determine how shoot and root-rhizome characteristics of four RP entries (?Florigraze?, ?Ecoturf?, ?UF Peace?, and ?UF Tito?) vary during a February through August planting period and relate these changes to subsequent establishment performance in the field near Citra, FL. Herbage mass (HM), leaf area index (LAI), and root-rhizome mass (RM) were quantified biweekly in RP nursery plots of all four entries. Rhizomes were planted at the same dates (PD), and emerged shoot number (ESN) and RP ground cover (GC) were quantified 12 wk after planting. At all sampling dates (SD), Florigraze RM was less than the other entries. Variation in RM for Ecoturf, UF Peace, and UF Tito followed similar trends, decreasing slightly between the first two SD, followed by an increase to the greatest values recorded at the third SD, after which, RM plateaued. The LAI of all entries increased at a relatively slow constant rate until the sixth SD, after which it approximately doubled by the seventh. Florigraze presented the smallest LAI throughout. Variation in HM for all entries followed similar trends, increasing at relatively constant rates throughout the period, with Florigraze HM consistently being least. Shoot number and GC were least for the second PD, reflecting low RM at that date, GC was greatest following the fourth PD, and ESN was greatest at PDs one, four, and five. Florigraze ESN and GC were least at all PD. Early results suggest RP entry has greater effect on establishment performance than specific shoot or root-rhizome characteristics, but research is ongoing.
