Perhaps you should try some spelling variations:
yield processing » field processing (Expand search), fields processing (Expand search), seed processing (Expand search)
decreases yield » increases yield (Expand search), decreases cell (Expand search), decreases il (Expand search)
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (Expand search)
at decreases » salt decreases (Expand search), and decreases (Expand search), but decreases (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)
decrease il » decreased il (Expand search), decrease in (Expand search), decrease hiv (Expand search)
il decrease » l decrease (Expand search), will decrease (Expand search), oil decreases (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease at decreases yield processing ) OR ( decrease faster decrease il decrease ))~.
