\begin{abstract}
\normalsize{
Atrazine, one of the most important s"=traizine herbicides, is used as selective pre"=emergence and early post"=emergence herbicide to control annual weeds mainly in maize and sugarcane production systems. Due to its moderate persistence in soil and its high leachability, it may lead to the contamination of groundwater resources. In addition, atrazine may be harmful to certain rotation crops and thus, the soil should be analysed before planting. In order to evaluation and comparison of pea, bean and lentil sensitivity to atrazine residue in soil, with 6 crops two experiments was conducted in field and greenhouse conditions. First experiment was conducted in field soil treated with atrazine based on split plot and evaluate in greenhouse conditions. Treatments in this experiment included 2 level of organic manure application rate (0 and 50 tone per hectare) as main plots and 2 level of atrazine application rate (2 and \mbox{4\,kg} atrazine a.i.) as sob plots. After corn harvesting soil sampled at 0--15 centimeters soil surface layer in each plots in 15 points and after mixing them, wheat, barley, sugar beet, pea, lens, rape, bean and tomato planted in pots at greenhouse at pots. Second experiment conducted in greenhouse to evaluation of simulated atrazine residue  in soil in completely randomised design. Treatments included atrazine residue concentrations (0, 0.2, 0.5, 1, 5, 10 and \unitfrac[15]{mg}{kg} soil) and above crops. Results showed atrazine residue didn't effect on crops growth in field experiment, but bioassay experiment(second experiment) showed, pea, bean, lentil, sugar beet, barley, wheat, rape, tomato and  onion  were tolerant to simulated atrazine residue respectively.}
