Murray State University was asked to compare different amendment percentages of worm castings incorporated into a substrate and two different soilless substrates for bedding and vegetable production by Ferry-Morse Seed Company. Both studies were performed at Murray State University's Pullen Farm Greenhouse Complex during fall 2004. Lycopersicon esculentum `Early Girl' was chosen to represent the vegetable plant category because of consumer popularity. Amendment percentages of 0%, 10%, 20%, and 30% of worm castings were incorporated into a soilless media substrate for Treatment 1. Treatment 2 was the same with the addition of soluble fertilized when plants were watered. Visual differences were found between Treatments 1 and 2. Zinnia elegans `Giant Cactus' were grown from seed to test chlorophyll levels, germination rates, and root:shoot ratios in Jiffy Professional Seed Starter Mix Plus and Ferry-Morse Seed Starter Mix. Statistically significant differences were found in dry root and shoot weights, along with leaf chlorophyll levels.
