Irrigation with contaminated Arsenic (As) water is greatly correlated increased soil As along enhanced uptake in plants, which turn biologically accumulates different parts of the plant at toxic levels. The current study aimed characterization and mitigation contamination through irrigation varietal selection. Characterization arsenic was done staggered random sampling. Experimental plots were laid highly farmer's field three rice varieties moisture regime randomized block design keeping summer as standing crop. According to Artificial Neural Network (ANN) study, phosphorus, followed by pH, Nitrogen, Potassium have been found be more sensitive regulating As. Alternate Wetting Drying (AWD) has significantly less concentration when compared Saturation (SAT)<Continuous Submergence (CS). Interestingly, maximum transfer from grain observed AWD, least use irrigation. Transfer factors (TFs) for cultivar IET-17430 IR-36> IET-4786.
