Effects of organomineral fertilizers on yield and quality in white cabbage (Brassica oleracea var. capitata L.) cultivation in hatay-yayladag region

This study was carried out to reveal the effects of organomineral fertilizers on yield and quality in cabbage (Brassica oleracea var. capitata) cultivation in Hatay / Yayladagı region. Six combinations of mineral and organomineral fertilizers were used in the experiment. These were (OM: Organo Mineral Fertilizer, M: Mineral Fertilizer); 0%OM+100M, 25%OM+75%M, 50%OM+50%M, 75%OM+25%M and 100%OM+0%M. While the fertilizer belonging to Toros company with a content of 15.15.15% NPK was used for mineral base fertilizer, the fertilizer of Organiksa company with a content of 15.15.15% NPK+15% organic matter was used for organomineral base fertilizer. Organomimeral fertilizer source for top fertilization was Instela Yield from Bactogen company contained 20% organic matter and 5.0.30 NPK+2Mg+trace nutrients. Mineral fertlizer sources for top fertilization were ammonium sulfate, calcium nitrate, potassium sulfate and magnesium sulfate. In order to determine the effects of organomineral fertilizers total cabbage yield, cabbage head fresh weight, cabbage head diameter, cabbage head height, cabbage firmness, number of leaf, leaf thickness, vitamin C, total phenol, total flavonoid contents, and macro-micro mineral nutrient contents. As a result, in terms of yield and cabbage characteristics examined, 50%OM+50%M application is recommended first and 75%OM+25%M application is second. Key words: Cabbage, yield, plant nutrition, organic matter, crop quality
