Vermiculite–perlite–clay (Putnam subsoil) mixtures with added nutrients were evaluated as growth media for periods up to 112 days in 3.8-liter jars using tomato (Lycopersicon esculentum Mill. cv. Patio Hybrid) as a test plant. Although vermiculite–perlite (V–P) ratio had no effect, subsoil levels above 50 g/jar and low N rate (22.5 meq/50 g subsoil) gave greatest growth of 42-day transplants. For long-term periods (112 days), only fruit yield was affected by V–P ratio, a 1:1 (vol/vol) proportion giving the highest yield. Large yield increases were obtained by increasing subsoil to the 150-g or 300-g levels. Fresh and dry plant weights increased with each increment of subsoil, and high N rate (45 meq/50 g subsoil) increased both vegetative growth and fruit yield to levels approaching those obtained with Cornell peat-lite mix A. The V–P clay mixes held more than twice the available moisture present in the peat-lite mix.
