This research was conducted to determine the relationships among soil type, soil moisture, and various levels of seed vigor of sunflower (Helianthus annuus L.) and safflower (Carthamus tinctoious L.) pure live seed emergence (PlS). The experiment included three soil types were; silty clay (Vertic Haplaquols, fine montmorillonitic, frigid), which contains 11% sand,42% sand,47% clay; silt loam (fine silty, mixed Udic Haploborals), which contains 30% sand,45% silt, and 25% clay; maddock sandy loam (sandy, mixed Udorthentic Haploboroll), which contains 57% sand,30% silt, and 13% clay. Soil types were equilibrated to 15%, 30%, and 45% of the moisture holding capacity. Results indicated that soil type (silty clay, silt loam, and sandy loam) and soil moisture level (15, 30, and 45% water holding capacity) had a significant (P<0.01) effect on seedling emergence of both crops. Percent pure live seed emergence of low-vigor seed lots of both crops was significantly (P < 0.05) reduced to a greater degree than was high vigor seed lots at low soil moisture content, and silty clay soil type.
