Abstract

Potted `Boaldi', `Red Akron', and `Yellow Boaldi' growth performance were evaluated in eight substrates and four N rates. The substrates included Sunshine Mix 1, Pro Gro 300S, and six compost blends. The compost feedstocks were polymer dewatered biosolids (PDB) blended with poultry litter (PL) or yard wastes (YW) and peat:perlite at final ratios of 4:2:1:1, 3:3:1:1, and 2:4:1:1. Plants received N at 75, 100, 150, or 200 mg•L-1 from 21N-2.2P-16.6K twice a week. Number of flowers, height, diameter, and grade of plants that received N at 200 mg•L-1 treatment were significant better than those received the other N treatments. For all compost blends, premium-quality plants were produced with N at 200 mg•L-1 treatment and good-quality plants were obtained with the remaining N treatments. The control substrates produced good quality plants with N treatments at 150 and 200 mg•L-1, the remaining N treatments resulted in plants that were only salable at reduced price. `Red Akron' is a free-branching spray cultivar, had more flowers and branches than the other two cultivars.
