Özet

Greenhouse melon was grown by organic nutrition in 1:1 cocopeat-perlite mixture (v/v). The licensed fertilizers in organic farming were the treatments of the experiment. Three different organic fertilizers were compared to each other and a control. The treatments with their trade names were; 1) Biofarm (liquid), 2) Complex (liquid), 3) Pattrone+Chamlica (powder), 4) Control. The control plants were fertigated by the conventional nutrient solution that was prepared by synthetic inorganic fertilizers. The experiment was carried out in the glasshouse during the spring cultivation period under Mediterranean climate conditions. Plant growth parameters (plant height, total shoot fresh weight, number of leaves plant(-1), stem diameter) were not significantly affected by the treatments. However, melon yield was higher in the organic fed plants in comparison to control ones. The melon plants fed with complex fertilizer produced the highest yield. It was 74% higher than the control. The other two organic fertilizers, Biofarm and Patrone+Chamlica, produced 17 and 15% higher melon yields than the control, respectively. Melon fruit total soluble solids (TSS) and fruit mean weight were similar in the different organic fertiliser's fed plants and higher than the control.
