Abstract
The effects of soil solarization and formalin fumigated soils on growth and fruiting quality and quantity of yield in strawberry were studied during 2005 – 2007.There were twelve treatments included three treatments of soil sterilization formalin fumigation, soil solarization, untreated (control), and four dates of transplants lifting with four replicates.Results revealed that vegetative growth characters i. e number of main runners per plant, number of leaves per plant, number of roots, root length, transplants per plant, crown diameter and plant fresh and dry weight were significantly increased by using soil solarization as compared with formalin fumigation or untreated soil ( control ) .
It is note worthy formalin fumigated soils tended to increase the vegetative growth characters; however this tendency failed to reach the
5 % level of significant.
Also, significant increase was obtained in early and total yield and average fruit weight as well as total soluble solids, ascorbic acid and total acidity contents when using soil solarization treatment compared with formalin and untreated soil (control).
Formalin fumigated soils treatments, also, tended to increase the early and total yield, however, this tendency failed to reach the 5 % level of significant.
Results indicated, also, that in order to improve the vegetative growth and to increase quantity and quality of strawberry yield of cv. Camarosa, it is recommended to using soil solarization.Soil solarization improve plant growth and increase yield over non- solarized control. It is proved to be an efficient technique for vegetable crop production.
Solarization of open field prepared for vegetable nurseries very efficient for controlling weeds and other pests. The nursery produced healthy vegetable transplants.
