Bahiagrass cultivar trial.
This trial included six entries of bahiagrass and was planted on 16 April 1997 on a Dothan fine
sandy loam (Plinthic Paleudult). An application of 400 pounds per acre of 8-24-24 was made on
13 April 00. Ammonium nitrate was applied at 100 pounds per acre on 22 June, 11 July, and 8
Aug. 00. Harvests were obtained on 1 June, 6 July, 3 Aug., 20 Sept., and 27 Nov. 00. Yield data
are presented in Table 4. It appeared that the dry season reduced the yields to some extent. The
yields of Tifton 18, 23, 7, and 9 in descending order of average yield were not significantly
different. Argentine yielded significantly more than Pensacola.


Warm-season perennial grasses.
In the 1999-2000 season, Flame crimson clover was overseeded on the eight perennial grasses:
Tifton 9, Tifton 18, Pensacola, and Argentine bahiagrass and Tifton 85, Florakirk, Tifton 78, and
Coastal bermudagrass. It was also overseeded on four sets of well-prepared plots. The data for
the clover yield has been presented in WFREC Research Report WF00-11. These are relatively
old plots of grass, and the trial is located on an Orangeburg sandy loam (Typic Paleudult). An
application of 400 pounds per acre of 8-24-24 was made on 13 April 00. Ammonium nitrate was
applied at 100 pounds per acre on 11 July and 11 Aug. 00. Harvests were obtained on 4 May,
7 July, 4 Aug., and 21 Sept. 00. The season was hot and dry. The plots which had been well-
prepared for clover were allowed to produce whatever volunteer grass and weeds which
appeared. Yield data are presented in Table 5. Tifton 18 and Tifton 9 bahiagrass produced the
most dry matter.


Summer annual grasses.
This trial contained 10 millet entries, 10 sorghum-sudangrass hybrid entries, and one forage
sorghum entry. The latter should have been in a silage trial, but we didn't conduct one so I just
put it in this trial to see what happened. The trial was planted on 28 April 00 on an Orangeburg
sandy loam (Typic Paleudult). See Table 2 and note that we got 0.15 inches of rain in the whole
month of May. Only because we had good moisture at planting did we get a stand, and it was
slow to develop, and was less than desired. An application of 300 pounds per acre of 8-24-24
was made on 22 May 00. Ammonium nitrate was applied at 100 pounds per acre on 23 June and
24 Aug. and at 200 pounds per acre on 8 Aug. 00. Four harvests were obtained. These were on
22 June, 20 July, 17 Aug., and 27 Sept. 00. Yield data are presented in Table 6, and maturity data
are presented in Table 7.


Gamagrass and Pennisetum orientale.
Five gamagrass entries and six introductions of Pennisetum orientale along with a Big bluestem
entry were set into a replicated row trial on 17 September 98. Plants were added as seemed
necessary on 28 April 99. These additional plants were from the greenhouse. The trial was
located on an Orangeburg sandy loam (Typic Paleudult). An application of 400 pounds per acre
