MULTIDISCIPLINARY APPROACH TO VALIDATE COMPOST USE IN VEGETABLE CROP SYSTEMS IN CAMPANIA REGION (ITALY): EFFECT OF COMPOST FERTILIZATION ON PROCESSING TOMATO IN FIELD CULTIVATION

The effects of compost obtained from the organic fraction of municipal solid wastes on yield and quality of processing tomato in field cultivation were evaluated.
Seven treatments were applied: 15, 30 and 45 t ha^-1 of dry compost, mineral treatment (150 kg N ha^-1, 200 kg P₂O₅ ha^-1, 120 kg K₂O ha^-1), 15 t ha^-1 of dry compost plus 25% and 50% of mineral nitrogen given in mineral treatment, and no-fertilization (control). The 30 and 45 t ha^-1 of dry compost, 15 t ha^-1 of dry compost plus 37.5 or 75 kg ha^-1 of nitrogen fertilizer, and chemical fertilisation gave the same yields, higher than those obtained with 15 t ha^-1 of dry compost and no-fertilization.
Virus disease incidence resulted the highest for 45 t ha^-1 of dry compost and chemical fertilized treatments.
No differences were observed for chemical analyses of the fruits, except for the lowest value of Hunter colour of the fruits in non-fertilized plots.
