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 Figure 3. Four year average yield (ton/ha) of cultivars included in the warmer northern irrigation areas during the period from 2012 to 2015 Table 3.
