Perlite as a growing medium in high density tomato and cucumber culture

, : Perlite as a growing medium in high density tomato and cucumber culture. Acta Horticulturae (26): 149-158

A cropping system using wide plastic tubes filled with perlite is described in which the tubes are spaced upright at 3- to 6-ft intervals along a wire framework to form 2 sides of an isosceles triangle with a 5-ft base, plants being inserted in the tubes at various heights at 1-ft spacing and trained horizontally on the framework. With tomatoes, despite difficulties in feeding and watering, some flushes yielded up to 40 tons/acre, yields with Pepo being particularly impressive.
