| Abstract:
The experiment was conducted in on the greenhouses of the Vegetable Growing Department of the Horticultural Faculty, between 2002 and 2003. The influence of compost types and organic mixtures on tomatoes were investigated. Trident and Lustro cultivars were used under the following variants: V1 the control variant (no fertilization), Trident; V2 mixture of forestry compost 50% and peat 50%, Trident; V3 mixture of peat 60% and perlite 40%, Trident; V4 peat 60% and forestry compost 40%, Trident; V5 mushroom compost, Trident; V6 crop-residue compost, Trident; V7 the control variant (no fertilization), Lustro; V8 mixture of forestry compost 50% and peat 50%, Lustro; V9 mixture of peat 60% and perlite 40%, Lustro; V10 peat 60% and forestry compost 40%, Lustro; V11 mushroom compost, Lustro; V12 crop-residue compost, Lustro. On March 18 we planted the tomatoes (4.2 plants /m2). The organic mixtures were applied once (fundamental fertilization rate of 25 t/ha). The experimental design was organized as three-repetition plots. The growing and developing dynamics of the studied plants, soil and organic mixtures analyses, and yield and yield quality were measured. Mushroom compost (98.5 t/ha in Trident and 95.1 t/ha in Lustro) and the peat 60% and perlite 40% mixture (97.2 t/ha Trident and 96.5 t/ha Lustro) for both cultivars had the best results. | |
