Abstract

This study was carried out at Süleyman Demirel University Agricultural Research and Experimental Station to compare the effects of conventional and organic production systems on yield, quality and plant characteristics of Joker F1 determinate tomato cultivar. First, four different doses (0-70-140-210 m3/ha) of the manure applications in both conventional and organic production were compared. Then, two plant activators (Crop-Set and ISR 2000), two microbial fertilizers (Bionem and Natural Bioplasma) and all possible combinations of these two were compared in organic production only. At the end of the experiments, it was observed that yield ranged from 48.7 to 72.3 tons/ha and early yield ranged from 26.5 to 47.2 tons/ha. The average fruit weight was between 143.26-167.02 g. At the end of the experiment, the applications resulted considerable variations in vitamin C (15.91-23.70 mg/100 g), soluble solid content (% 3.52-4.18), firmness (1.46-1.87 kg/cm2) and titratable aciditiy (% 0.232-0.428).
