So the responseProcessing for such an item might look like this (the 
SCORE value of 0 can be implied but I've added to make the code clearer 
and it does no harm):

<responseProcessing>
  <setOutcomeValue identifier="SCORE">
    <baseValue baseType="float">0</baseValue>
  </setOutcomeValue>
  <responseCondition>
   <responseIf>
    <substring caseSensitive="false">
     <baseValue baseType="string">mecanisation</baseValue>
     <variable identifier="RESPONSE"/>
    </substring>
    <setOutcomeValue identifier="SCORE">
     <sum>
      <variable identifier="SCORE"/>
      <baseValue baseType="float">0.5</baseValue>
     </sum>
    </setOutcomeValue>
   </responseIf>
   <responseIf>
    <substring caseSensitive="false">
     <baseValue baseType="string">fertilization</baseValue>
     <variable identifier="RESPONSE"/>
    </substring>
    <setOutcomeValue identifier="SCORE">
     <sum>
      <variable identifier="SCORE"/>
      <baseValue baseType="float">0.5</baseValue>
     </sum>
    </setOutcomeValue>
   </responseIf>
  </responseCondition>
</responseProcessing>

To accommodate different spellings you might want to experiment with the 
patternMatch operator instead of the simple subString as this will 
enable things like:

<patternMatch pattern=".*(mecanisation|mechanization).*">
  <variable identifier="RESPONSE"/>
</patternMatch>

...assuming a single line of input.
