Abstract

Field experiments on tomato and lettuce seed-bed solarization were
conducted at Deir-Ezzor in Syria. The well prepared and pre irrigated seed-bed
plots were covered with 40 micron thick clear polyethylene mulches for a
duration of 6 weeks prior to tomato and lettuce planting for the two seasons
(2009, 2010).
Soil solarization raised the maximum of soil temperature at 0 , 5 and 10
cm depths to 58, 50 and 46 °C, with increase of 9.9 and 7.5 over the nonsolarized treatment respectively .
Solarization resulted in approximately 98 % and 80 % reduction for annual
and perennial weeds. Seed-bed solarization increased healthy tomato and
lettuce transplants production as compared with the untreated plots. It also
produced taller transplants with more leaves and higher fresh weight.
