Fertility Trials with Florakirk Bermudagrass and Chi'cry
and Harvest Date Trial with Florigraze Rhizoma PeTnart

L. S. Dunavint FEB 26 1996

Conversion factors are given in Table 1 for the use of tho~ ipvsit;adFlffIt to
convert to metric units. Climatological data are presented in Table 2.

Florakirk Bermudagrass.
This reports data for 1995 from a trial which has been conducted for several
years. The plots were established to Florakirk in 1988. They were located on
an Orangeburg sandy loam soil (Typic Paleudult). The fertility treatments
were very low, low, medium, high, and very high. The very low treatment was
31.25 pounds per acre of N per year, and each succeeding rate was twice the
preceding rate. All were balanced in a 2-1-1 NPK regime. All of the P and K
and 1/3 of the N was applied on 10 April 95. Another 1/3 of the N was applied
on 7 July 95, and the final 1/3 was applied on 14 August 95. Harvests were
obtained on 15 May, 30 June, 31 July, 29 Aug., and 27 Sept. 95. Yields of dry
matter varied from 3,570 pounds per acre at the very low level to 15,580
pounds per acre at the very high level. Data are presented in Table 3.

Chicory.
This fertility trial was imposed on plots of chicory planted on 18 March 94.
They were located on an Orangeburg sandy loam soil (Typic Paleudult). The
treatments were 100, 200, 300, and 400 pounds per acre of ammonium nitrate
applied following harvest. Fertilization in 1995 included 400 pounds per acre
of 8-24-24 fertilizer on 10 April 95 and ammonium nitrate at the indicated
rates on 7 June, 10 July, and 18 August. Harvests were made on 5 June, 10
July, 11 Aug., and 8 Sept. 95. Dry matter yields are reported in Table 4 and
indicate no response by the chicory to N fertilization in this trial. The
data are for chicory only and do not include the total biomass from the plots
which included a lot of weedy material after the first harvest. Season-total
dry matter (including weeds) is given in Table 5 and does show a response to
N. It is probable that the lack of response by chicory was due to a lot of
variability in stands which was more apparent after the first harvest. Other
observations with chicory at the WFREC, Jay have indicated difficulty in
obtaining uniform stands.

Florigraze Rhizomr Peanut.
A times-of-harvest trial was conducted with Florigraze rhizoma peanut in 1995.
Two old areas of peanut were used in the trial. One, located on an Orangeburg
sandy loam soil (Typic Paleudult), was established in December, 1979 and the
other, located on a Red Bay sandy loam soil (Rhodic Paleudult), was established
in January, 1976. The peanut areas were fertilized in 1995 with 300 pounds per
acre of an 0-30-15 fertilizer on 12 May. Each area was divided into four
replications of plots for harvest three, two, and one times each. Plots harvested
three times were harvested on 27 June, 23 Aug., and 19 October. Those harvested
twice were harvested on the August and October dates, and those harvested once
were on the October date. Yield data are given in Table 6. On both soils, there
was no real difference between yields when harvested two or three times, but a
considerably lower yield was obtained from a single harvest.
