Perhaps you should try some spelling variations:
decrease further » increase further (Expand search), disease further (Expand search), decrease after (Expand search)
further decrease » further increase (Expand search), faster decrease (Expand search), urea decrease (Expand search)
decrease yiel » decreases yield (Expand search), decrease il (Expand search), increase yield (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search)
yiel pattern » yield pattern (Expand search), diel pattern (Expand search), diel patterns (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease NOT decrease the decrease ) OR ( decrease further decrease yiel pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease NOT decrease the decrease ) OR ( decrease further decrease yiel pattern ))*.
