This study was conducted out to determine performance of important walnut cultivars in Tokat ecological conditions. Bilecik, Sebin Yalova 2, 198/110, and 32/B-18 walnut cultivars were used in this study. The average of nut weight in investigated walnut cultivars was determined as 10.23 g, 11.36 g and 17.39 g, 12.01 g, 12.40 g in respectively. The mean of kernel weight in investigated cultivars was observed as 5.73 g, 7.44 g, 8.75 g, 6.03 and 6.85 g in respectively. The mean of number nuts per tree was determined 82.66, 50.33 and 23 in Bilecik, Sebin and Yalova 2 in respectively in 1997. These values were observed as 127.5, 245.3 and 52.2 in 1998. The content of macro and micro nutritions is determined as following: N, 1.88-3.55%; P, 0.15-0.43 K, 1.25-3.25 %; Ca, 0.75-1.19%; Zn, 20-77.5 ppm; Mn, 15-100 ppm; Na; 83-252 ppm; and Fe, 80-290 ppm
