the highest yield, followed by SST
875 (8.62 ton/ha) and SST 835
(8.58 ton/ha) (Figure 4).
KwaZulu-Natal Irrigation areas
KwaZulu-Natal was the region
worst affected by the heat and
drought in 2015. The average yield
was low at 5.42 ton/ha. However,
the combined analysis showed that
Renoster (6.18 ton/ha), SST 8135
(6.13 ton/ha), SST 884 (6.01 ton/ha)
and SST 8134 (6.00 ton/ha) had the
highest yields (Table 4). The yields
of these cultivars were not significantly different from each other.
The four year average grain yields
indicated that SST 806 (7.49 ton/ha)
produced the highest yield, followed by SST 835 (7.43 ton/ha) and
Krokodil (7.30 ton/ha) (Figure 5).
Average hectolitre mass for 2015
Figure 4. Three year average yield (ton/ha) of cultivars included in the
Highveld irrigation areas during the period from 2013 to 2015
was 81.60 kg/hl. Grain protein content was very high during 2015 at
14.57%. Falling number values
were generally high, with an average of 308 seconds.
