Perhaps you should try some spelling variations:
irrigation requirements » irrigation equipment, nutrition requirements
requirements data » requirements a, requirements case, requirements based
data dimensional » data dimension, data dimensions, meta dimensional
bioarrays from » microarrays from
plant from » plants from, plant food, plant form
bioarrays » bioardays, bioarray, bioarways
rays » days, ray, ways

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

• Performing a fuzzy search may retrieve terms with similar spellings: irrigation requirements data dimensional ((bioarrays from) or (((plant from) or (rays from))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: irrigation requirements data dimensional ((bioarrays from) OR (((plant from) OR (rays from)))).
• Adding a wildcard symbol may retrieve word variants: irrigation requirements data dimensional ((bioarrays from) or (((plant from) or (rays from))))*.
