TOMATO FRUIT YIELD AND QUALITY ARE AFFECTED BY ORGANIC AND INORGANIC FERTILIZATION AND CADMIUM POLLUTION

The effects of different concentrations of cadmium (Cd) (0, 3, 30, and 100 mg . kg(-1)) and different fertilizers on the yield and quality o f tomato (Lycopersicon esculentum Mill cv. Marmande) fruits were evalu ated in a calcareous soil (Haploxeroll calcic). Two types of fertilize r were applied, one organic with the addition of sewage sludge and oth er inorganic with amounts of nitrogen (N), phosphorus (P), and potassi um (K) equivalent to those due to the sewage sludge incorporation. Pla nts fertilized with sewage sludge produced the highest yield. Very lit tle difference was found in fruit quality due to fertilization and the presence of Cd had no significant effect on yield and quality of frui t.
