a study of the effect of seed sowing design and depth on seedling emergence and viability in order to domestication nowruzak (salvia leriifolia benth.)

abstract nowruzak (salvia leriifolia) of lamiaceae family has a good capability for domestication in khorasan’s natural habitats. in order to investigate the effect of sowing design and depth in seedling emergence and permanence, a split plot experiment based on a randomized complete block design was performed with three replications. results indicated sowing design in all three parameters, sowing depth in number of days for emerging were significantly differents (p<0.01), sowing design×depth was significantly different in percent emergence (p<0.01) and seedling permanence (p<0.05). the most emergencye percentage (28%) was in plot sowing and 1 cm sowing depth. more sowing depth increased the number of days to emergence, and the most percentage of viability (68.7%) was in plot sowing and 1.5 cm sowing depth.
