| Abstract:
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. | |
