Özet:

This research was carried out with the aim of determining the effect of different amounts of humic acid applications on the yield and quality components of some potato varieties at the Konya Soil, Water and Combating Desertification Research Station Management field trials in 2015. Three different potato varieties (Agria, VR808, Brooke) and four different humic acid doses (0, 3, 6, 9 l/da) as a material were used in the trial. Varieties are considered as main and applications are considered as sub-plot. Depending on the doses of humic acid used in the research, the plant height was 36.3-60.4 cm, the number of stalk per plant was 3.1-6.1 units, the number of tuber per hill was 5.5-9.4 units, the tuber yield per hill was 812.0-1228.7 g, total tuber yield per decar was 3313.4-4454.1 kg. According to the research, it has been found that features such as number of stalk per plant, number of tuber per hill, tuber yield per hill, total tuber yield per decares have been observed significant increases in increasing humic acid applications. The highest tuber yield per hill was obtained at 6 l/da humic acid dose and Agria variety in point of varieties (1228.7 g).
