Özet

In the study conducted during 2013 and 2014 years, organic tomato production has been performed using 5 different treatments (control, Crop-Set, Soil-Set, Manda 31 and conventional) including three doses (0, 125, 250 kg/da) of solid organic fertilizer produced via fermentation of plant protein sources and cattle manure in an experimental set up of split plot design. At the end of the study, the N, P, K, Ca, Mg, Mn, Fe, Zn and Cu elemental analyses were performed using tomato leaves in order to determine the nutritional position of the tomato plants. The results showed that the N, P, K Ca, Mg and Fe contents of tomato leaves increased in all doses as compared to the 0 kg/da Biofarm Humus dose and in all treatments as compared to the control treatment.
