Conclude harvest (6)
I believe the answer is:
gather
I believe this is a double definition.
'conclude' is the first definition.
(gathering is a kind of concluding)
'harvest' is the second definition.
(I've seen this before)
(Other definitions for gather that I've seen before include "... will proverbially do this" , "From information given, learn" , "Collect; understand" , "Accumulate, garner" , "Harvest or learn by inference" .)
