Bridging the yield gap

Plain text source: 
Closing the exploitable yield gap (80% of Yw - Ya) would increase yields by 1.2 t/ha to raise the regional average to 2.9 t/ha... There is a strong correlation (r 2 = 0.72) between Yw and Yg (Figure 5) indicating that across all locations and seasons, the higher the yield potential the higher the yield gap... Average annual values of Ya, Yw, Yg and Y % (figure 7) per SLA show that some SLAs have larger yield gaps than others...
