 An experiment conducted in 1990,
2000 and 2001 on Île d’Orléans, Quebec, has determined which
plastic mulch (black, silver on black, or thermal/photoselective
green) and which shelter (floating cover, mini-tunnel or no
protection) results in the greatest earliness and productivity
in the off-season strawberry variety Seascape (Fragaria x
ananassa Duchesne) in the first and second growing years.
The various types of plastic mulch that were used had little
impact on total yield, marketable yield and average marketable
strawberry weight. Nevertheless, the black mulch is the most
satisfactory in terms of its ability to adapt to strawberry
plant age and weather conditions. Although using shelters was
not effective in increasing earliness in plants in the first
growing year, using floating covers (tarpaulins) in the second
growing year was beneficial. The various shelters had little
impact on productivity, however, no matter the production period.
