Abstract

The study was conducted using plastic pots during the growing season 2020-2021 in private field crops at the Holy Karbala Governorate to study the effect of the quality of water, soil moisture and potassium levels on lead and cadmium of wheat plant var. A.L. baraka. A factorial experiment was carried out using a completely randomized design (C.R.D.) with three replications, which included two types of irrigation water treated heavy water and soft water, three levels of field capacity, i.e., %, 50% and 100% and four levels of potassium, i.e., 0, 1000, 2000 and 3000 mg. L-1 The experiment included 72 experimental units. The results were statistically analyzed, and the means of treatments were compared using the least significant difference under the probability level of 0.05. The following characteristics were measurements: The element lead and cadmium in the roots, leaves and leaves were obtained; results were statistically different in the traits under study; treated water treatment gave the highest values for the concentration of lead and cadmium in leaves and grains, their averages were 17.38 mg-1 0.691 mg mg-1 , 0.207 mg. .061 mg.kg-1 and 0.031 mg.kg-1 and 6.48, respectively. The highest concentration is 6.69 mg. Direct lead to water (treated) was 3.983 over its counterpart in plain water 1.035, with an increase of 298.3%. The heavy water treatment gave a very high value with leaves cadmium concentration of 0.6916 mg. Cadmium 1 mg.kg.compared to the treatment of soft water, which gave the value 0.0311 mg.kg-1 , with an increase of 565.59%.Treatment of 100% of the field capacity value gave the highest lead and cadmium concentration values in roots, leaves and grains 14.41 mg-1 ,2.716,1.389,0.480,0.383 and 0.181 sequentially. The addition of (3000) potassium decreased the lead concentration in the roots, leaves and grains due to potassium application of 9.73 mg1 ,2.170,1.056,0.39,0.233 and 0.079 sequentially. Keywords: lead, cadmium, wheat plant, water quality, water stress, potassium.
