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)
decrease will » decrease with (Expand search), decrease cell (Expand search), decrease il (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)

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

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