The consumers and food processing industries prefer the organic food items,because they also ensure health safety. Many synthetic and organic types of mulch have been used in the raised bed culture system. Plants grown on black plastic mulch produced more runners and fruit than plants grown on clear or white plastic mulches and that total fruit mass was greater with black and clear plastic mulches than with bare soil. The total soluble solids represent the acid, sugars, soluble salts, proteins and other dissolved substances of the cell sap. The total sugars ranged between 50,73 mg/100 g s.p. and 113,43 mg/100 g s.p., and the soluble solids ranged between 7,19% and 13,11%. A strawberry with very low sugar and acid content taste flat. In the same time strawberry are economically and commercially important and widely consumed fresh or in processed forms, such as jams, juices and jellies.
