A Research on Production of Rocket and Parsley in Floating System

Hale Duyar, Cenk Ceyhun Kiliç


In this research, the possibility of the production of rocket and parsley which have short production cycle and baby leaf vegetable, in floating system to reduce the concentration of nutrient solution; determination of the effects of yield, quality and leaf nutrient content was aimed. Research was carried out during the autumn and spring production seasons of 2010-2011. Standard nutrient solution ((mM) 12 N-NO3, 3.8 N-NH4, 2.8 P, 8.4 K, 3.5 Ca, 1.4 Mg, 9.5 Na, 8.0 Cl, 2.7 S, 0.04 Fe) was used as full dose (control treatment) and compared to half dose (1/2 dose) Hoagland nutrient solution. Both of the seasons in total yield were changed between rocket 975.81-1612.15 g m-2 and parsley 875.50-1093.50 g m-2 respectively. The results showed that using of floating system in Rocket and Parsley cultivation was successful and reduced the concentration of nutrient solution; variety and growing season at rates ranging from 13.7% to 24.8% compared to have showed reduce the yield. In this study, the effect of treatments to some quality parameters (dry weight, vitamin C, nitrate, pH ve EC) and nutrients removed by plant were determined. In addition, it was found that these values increased with increasing with the concentration of nutrient solution; however, vitamin C decreased in Parsley cultivation. When the results evaluated as a whole, it was concluded that using ½ doses decreased yield, some savings could be achieved in terms of nutrient solution consumed by the plant with the negative impact on the environment.
