ACIKGOZ, F. E., A. ADILOGLU, F. DAGLIOGLU, S. ADILOGLU, G. CELIKYURT and O. KARAKAS, 2014. The effect of increasing doses of nitrogen (N) application for some nutrient elements, vitamin C and protein contents of komatsuna (Brassica rapa var. perviridis) plant. Bulg. J. Agric. Sci., 20: 321-324
This study was conducted to determine the effect of increasing nitrogen (N) application on macro-micro elements, vitamin C, and protein contents of komatsuna. Four doses of N (N0: 0 kg da-1, N1: 10 kg da-1, N2: 15 kg da-1 and N3: 20 kg da-1) were applied as NH4NO3 fertilizer in greenhouse conditions. The content of Vitamin C decreased in the increasing doses of N. Vitamin C, for N0 dose was obtained as 29.28 mg 100g-1, for N2 as 21.54 mg 100g-1, increased with N fertilization. Protein content was positively affected of N fertilization and the protein content was found 32.97 % for N2 dose. K, Ca, Mg, Fe and Cu nutrient elements were found statistically insignificant, for N2 dose under increasing doses of N application; N found as 5.85 %, P 0.81 %, Zn 50 ppm.
