Effect of sowing dates on yields of CSW18 and other elite wheat cultivars

FIGURE 5.7
LHS picture shows the differential response to heading in two wheat cultivars.
(a) D2967 on first two beds and (b) CSW 18 on next two beds. Both cultivars were planted in
early October. Wheat cultivar HD2967 has completed heading in LHS 2 beds, however wheat
cultivar CSW18 (next 2 rows) is still in the heading process and will take another 10 days to
complete it. Picture on the RHS shows that early-planted CSW18 has improved head size
which improves crop productivity.
