The effect of location and harvest interactions on yield and some quality characteristics of Arapgir basil

It is reported that purple basil plant, which is one of the medicinal and aromatic plant species and widely cultivated in the Arapgir district of Malatya, differs morphologically and physiologically from other species. In this study, in the vegetation period of 2019, in three different locations; Yield and some plant characteristics of Arapgir Purple Basil, which received Geographical location at two different altitudes (Kozluk location; 914m, Boğazlı location; 1470m) in Malatya city Arapgir District and Malatya Turgut Özal University Faculty of Agriculture area (Battalgazi; 750m) in Battalgazi district of Malatya city. In the study, plant height, leaf area, leaf ratio, leaf length, leaf width, fresh herb yield, dry herb yield, dry leaf ratio, leaf color (L, a, b, Chroma, hue), anthocyanin amount, total antioxidant capacity, total phenolic content and essential oil content were investigated. According to the findings, among the locations the highest plant height (55.8 cm), leaf area (7.8 cm2/main leaf), leaf length (7.8 cm), leaf width (4.7 cm), fresh herb yield (2707.2 kg/da), dry herb yield (370.7 kg/da) were obtained from Kozluk location. According to harvest time, the highest plant height (58.6 cm), leaf area (8.1 cm2/main leaf), leaf length (8.1 cm), leaf width (4.9 cm), fresh herb yield (3461 kg), dry herb yield (469.4 kg/da), total phenolic amount (4479.6), essential oil rate (0.7 %) were obtained at the third harvest time. When the location and harvest times are evaluated together, it is seen that Kozluk and 3rd harvest periods come to the fore in terms of plant characteristics. There was no statistically significant difference in terms of anthocyanin content, antioxidant capacity and total phenol content among quality characteristics between locations and harvest times.
