The Effect of Different Row Spacings on Some Yield and Quality Characters in Borago officinalis L. (Borage) in Ecological Conditions of Menemen

This study was carried out in the field of organic production at the Menemen research and production farm of Ege University in 2014-2015 and 2015-2016. In this research that conducted for two years, were investigated of the effects of four different row spacings (30 cm, 40 cm, 50 cm and 60 cm) on some yield and quality characteristics of Borago officinalis L.. In the first and second years of the experiment, the plant height, 1000 seed weight, number of branches, number of inflorescences and seed yield were changed between 58.16- 77.00 cm, 65.86- 75.93 cm; 16.3- 17.0 g, 15.0-16.4 g; 5.96- 7.46 per plant, 6.55- 8.10 per plant; 27.40- 41.86 per plant, 31.50- 33.85 per plant; 44.38- 76.39 kg/da, 41.67- 79.72 kg/da respectively. In both experiment years, in investigated parameters were observed increase except 1000 seeds yields in these values with the increases of the distance between rows. Further oil ratio was determined in the range of % 29.96- 34.04 and % 30.13- 33.67 at the first and second years of experiment respectively. The result of the experiment indicated that there was a decrease in oil ratio as increases of the distance between rows. Analysis of fatty acids oil of Borago officinalis L. indicated that the ratio of palmitic acid, stearic acid, oleic acid, linoleic acid, ？-linolenic acid, eicosenoic acid and erucic acid were %13.10-13.31, %3.78-4.07, %20.26-20.74, %36.40-37.54, %18.20-18.71, %4.09-4.25 and %2.36-2.60 in averages of years respectively. In result, it is possible to say that 50 cm distance between rows must be applied in order to obtain an acceptable high level of oil content with seed yield in Borago officinalis L
