Perhaps you should try some spelling variations:
decreases yield » increases yield (Expand search), decreases cell (Expand search), decreases il (Expand search)
skins decreases » skins decrease (Expand search), seeds decreases (Expand search), walking decreases (Expand search)
decrease skins » decrease in (Expand search), increase skin (Expand search), decrease owing (Expand search)
yield objects » field objects (Expand search), fields objects (Expand search), field object (Expand search)
decrease any » decrease and (Expand search), decreases and (Expand search), decreased and (Expand search)
any decrease » and decrease (Expand search), can decrease (Expand search), may decrease (Expand search)

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

• Removing quotes may allow a broader search: (( decrease AND decrease any decrease ) OR ( decrease skins decreases yield objects ))~.
