| Abstract:
During the 1987–1988 and 1988–89 growing season an experiment was conducted in a cold plastic greenhouse of our Institute aiming to evaluate five substrates in two vertical systems with respect to their suitability for growing strawberries. The following substrates were evaluated: a. perlite 100%, b. perlite 90% + peat 10%, c. perlite 80% + + peat 20%, d. pumice-stone 80% + peat 20%, e. pumice-stone 80% + perlite 20%. They were placed either in polyethylene tubes,1.70m height and 0.15m diameter in a vertical position, or in pots of polystyrene placed one above the other in a column 1.70m in height. In both cases, 36 plants of the strawberry cultivar Brighton were planted in each column in August. A system for recycling the nutrient solution was applied. Yield was collected from December until June. About 65% of the yield was taken until the end of April. Data obtained indicate that strawberries grown on substrate composed of perlite 80% + peat 20% produced higher yield (250gr/plant) than those grown on the other substrates. There was no difference between polystyrene pots and polyethylene tubes with respect to yield. | |
