Field trials of the present study was realized in 3 isolation areas (3 different regions) as EK1102 variety in Eşrefli location, VE3060 variety in Aşağıpiribeyli location and PS4042 variety in Doğanyurt location - TURKEY according to split plot in randomized complete block design with 3 replications. The main plots consisted from the plant density for the line control (PS4042: 6200 plant da-1, VE3060: 5700 plant da-1, EK1102: 6500 plant da-1, 5000 plant da-1, 6000 plant da-1, 7000 plant da-1) and 4 potassium doses (0, 3, 5, 7 kg/da K2SO4) applicated According to results the following ranges were detected; 109.67-307.00 kg da-1 for grain yield, 9.33-12.33 for days emergence period, 68.00-77.67 for days flowering period, 76.00-168.00 cm for plant height, 17.00-27.00 cm for diameter of the head, 7.33-8.72 gr for weight of one hundred grains, 4.17-7.15 mm for seed diameter, 11090.88-14519.33 pieces for kernel kg-1. Consequently, results of the present research showed that, the lowest value was 11090 kernels kg-1 , PS4042 variety with 7 kg da-1 potassium dose application and 7000 plant da-1 sowing density while the highest value was 14519 kernel kg-1 and VE3060 variety with 5 kg da-1 potassium dose application and 5000 plant da-1 sowing density. It can be concluded that deep and various factors are needed to focus for more reliable data collection and adaptation to different ecologies.
