38580

To determine the appropriate sowing time in Van conditions for the cultivation of spinach in this study conducted two years, three sowing dates for autumn sowing-spring harvest (mid-October, the beginning and middle of November), four sowing dates for spring sowing-spring harvesting (mid-March , beginning, middle and end of April) were conducted. The first year, cv. Meridian and cv. Spinoza were used in the study and in the second year only cv. Spinoza was used in the study. Among the seed sowing times within the first year, the highest total yield (average 40.0 t ha^-1) was obtained by sowing in the middle of October. The first year the average yield of cv. Spinoza was 3.1 t ha^-1 higher than that of cv. Meridian. Among the seed sowing times in the second year, the highest total yield (45.7 t ha^-1) was obtained again from the time of sowing in mid-October. In both years, spring sowing encountered the problem of bolting.
