Highveld irrigation areas
The average yield of the Highveld
areas was 8.55 ton/ha. The combined analysis indicated that PAN
3497 (9.51 ton/ha), SST 8134 (9.26
ton/ha), SST 884 (9.03 ton/ha) and
PAN 3623 (9.02 ton/ha) had the
highest yields (Table 3). The hectolitre mass was acceptable for all cultivars, with an average of 83.39 kg/
hl. Average grain protein content
was also acceptable in 2015 at
11.60%. Falling number values
were generally high, with an average of 315 seconds. The three year
average grain yields indicate that
PAN 3497 (8.85 ton/ha) produced
