Our experiment demonstrated the high productivity of cucumbers, obtained
on an annual basis, with the successive cropping method under supplemental
lighting. As a result of high daily productivity, annual yields of 280 fruits m -2
could be produced with Method 2. However, this method does entail stops in
production between certain successive crops. Methods 3 and 4, although less
productive, provided good annual yields and necessitated two fewer successive
crops than Method 2. Moreover, these pruning methods require no cyclical
stops in production. However, Method 3 is of little interest due to a marked
decrease in production between the end of the main stem fructification and
the beginning of that of the secondary sucker. Method 4 did not present this
problem and is thus considered a promising pruning technique. An economic
analysis is necessary to determine if the production of 25 additional fruits m -2
year- 1 justifies the use of Method 2, which involves two more successive crops
per year than Method 4.
