Title:
EFFECTS OF SPENT MUSHROOM COMPOST ON THE PRODUCTION OF GREENHOUSE-GROWN CROPS

Author:
Joseph Dallon Jr

pp: 323-329

Abstract:
Selected cultivars of Chrysanthemum morifolium and Lilium longiflorum were grown under greenhouse conditions in different ratios of spent compost, and in two commercial growing preparations, with either a 14–14–14 slow release fertilizer, or with a 20–20–20 water soluble nutrient solution. In all cultivars of both plant species, the most commercially desirable plants were produced in spent compost and Speedel in a 1:1 ratio. Plants with the highest bud count were also produced in this mix. The shortest plants were produced in spent compost alone, which exerted a growth retarding effect in all media and nutrient combinations. Nutrient treatments alone had no significant effects on flowering, root development, or bud count.
