Conclusion from <strong>the</strong> three experiments<br />
• No yield reduction responses to shad<strong>in</strong>g <strong>of</strong> current cultivars<br />
suggest that <strong>the</strong>re were enough source (assimilates) to fill <strong>the</strong><br />
exist<strong>in</strong>g s<strong>in</strong>k.<br />
• No yield responses to irrigation but <strong>in</strong>creases <strong>in</strong> WSC<br />
rema<strong>in</strong><strong>in</strong>g <strong>in</strong> <strong>the</strong> stem at maturity <strong>in</strong>dicates that <strong>the</strong> s<strong>in</strong>k size <strong>of</strong><br />
<strong>the</strong> current cultivars are not large enough to accommodate <strong>the</strong><br />
available assimilates.<br />
• <strong>S<strong>in</strong>k</strong> size <strong>of</strong> <strong>the</strong> current cultivars are limited.<br />
• The rema<strong>in</strong><strong>in</strong>g question: do we have enough water to support a<br />
large s<strong>in</strong>k size crop?<br />
