Objective: This research was carried out as a greenhouse experiment in the form of a Completely Randomized Factorial Design (CRD) in three-run sequences. The research aimed at investigating the impacts of Nicosulfuron (Cruz) and Rimsulfuran (Titus) residues on the growth of wheat in two soil types which differed in their levels of organic compounds and salinity. Methods: Treatment of the experiment included six different doses of 0, 2, 4, 8, 40, 60 gr per hectare of rimsulfuran and 0, 0.1, 0.2, 0.4, 2, 3 liter per hectare of Nicosulfuron. Results: As per the results of the survey, an increase in the concentration of the herbicides caused a meaningful decline in the measured characteristics of the plant including the length and the wet and dry weight of the shoot and the root (P<0.01). According to I50 in other words a 50% inhibition of growth indicator, the weight of dry shoot showed the highest sensitivity to rimsulfuran in the soil coded B (1.26) and weight of dry root to Nicosulfuron in soil B (41.84).
