Marrar Grazing Wheat Trial 2005
NEW:
Final Report for soil water measurements in the
2005 Marrar Grazing Wheat Trial
The
Marrar Trial is one of several grazing wheat trials being carried out
in 2005 by Grain and Graze Murrumbidgee at three sites across the region
from Yerong Creek in the south west to Grenfell in the north east. An
agronomy trial involving several grazing wheat varieties is being carried
out at each of the three sites. Dry matter production, feed value, water
use, yield and grain quality are being measured. The 2005 trials are a
reduced version of the 2004 trials, with only 3 varieties of grazing wheat
(Marombi, Whistler and Wedgetail) and 1 regular wheat variety (Diamondbird).
Treatments include an early and late sowing time for the grazing wheat
varieties (May 4 and June 15), and a grazed and ungrazed treatment for
the late sowing of Wedgetail. Diamondbird is sown at the later time and
is ungrazed.
In
2005 the Marrar trial is being carried out on "Brigadoon", 8
km north of Marrar. As for the 2004 Marrar
Trial, continuous soil water measurements are being made in
3 treatments: Whistler
grazed, Wedgetail ungrazed and Diamondbird. Because of the good agreement
between replicates observed in the 2004 trial, this year soil water measurements
are being restricted to only one of the four replicate blocks (Rep 3).
Soil water sensors were installed at 8 depths from 0.2
m to 1.6 m below the soil surface at a location just downslope of the
middle of each of the three plots being monitored. For more detailed information
about the methodology, see "How the
measurements are made" and "Interpreting
the measurements".
