Abstract :To avoid harmful health effects of synthetic sugar and also due to human attention to supply sugar from natural sources, the interests of the sugar plants cultivation, especially Stevia rebaudiana have been increased. A field experiment was conducted to study the effect of planting density, cutting stage and cutting number on Stevia. In Çukurova region, which is classified as Mediterranean climate. The experiment conducted in a split plot design consisted of three planting density, 30 × 60, 45 × 60 and 60 × 60 cm in the main plot and two cutting time in various growth stages in subplots with three replications. Since there were two cuttings in the season, the differences between cuttings, statistical analysis was valued by using split-split plot design in time. Planting density significantly affected the dry leaf yield and the higher yield (110.9 kg da-1) was obtained from the plants, spaced 30 × 60 cm. Plants cutting at flowering stage had high dry leaf weight (20.55 g plant-1) and yield (84.70 kg da-1). Also, more dry leaf weight and yield were obtained from first cuttings. Leaves of closer plant densities produced high content of stevioside. Pre-flowering stage had significant effect on stevioside in the affirmative way.Keywords : Stevia, cutting, density, stevioside, yield
