INFLUENCE OF PLANT TYPE ON STRAWBERRY PRODUCTION IN A PEAT BASED MEDIUM IN HANGING CONTAINERS
A crop of strawberries was grown in an unheated glasshouse in 4 litre pots suspended at a height of 1.5 m above the ground. There were 4 plants per pot in a 75/25 peat/perlite medium. Pots were spaced at 40 cm in single lines 80 cm apart giving a plant density of 12.5/m2. Nutrient solution was applied at every watering at a pH of 5.5 and an EC of 1.6 mS/cm. The plants were brought into the house in the end of January and cropped from early May to mid-June. Four plant types were compared; 1. tip runners rooted in June and potted into their final pots in July, 2. cold stored runners potted in July, 3.cold stored runners planted into a waiting bed in July and then dug up and potted in December, 4. standard field plants dug up and potted in December. Plants potted in July had a higher fresh weight at the beginning of February but the early yield was best from the December potted treatments. Total production was higher with the two cold stored runner treatments which yielded an average of 3.5 kg/m2 of marketable fruit as against 2.75 kg/m2 from the other treatments.
