EFFECT OF MAGNESIUM AND CADMIUM SUPPLEMENTATION ON YIELDS AND QUALITY OF POPPY (Papaver somniferum L.)

Original language description

Abstract: In a vegetation pot experiment with poppy, 'Opál' variety, we explored the effect of soil supplementations of magnesium (0.78 g Mg.pot--1) and as foliar dressing (3 % solution) in the form of Mg(NO3)2 at a natural (0.14 mg Cd . kg--1) and increased level (1 mg Cd.kg--1) of cadmium in the soil on the chemical composition of the plants, seed yields, content of morphine in the straw and cadmium content in the seeds. The following six variants were used in the experiment: 1) N (control), 2) N + Mg(NO3)2 into the soil, 3)N + Mg(NO3)2 foliar dressing, 4) N (control) + Cd, 5) N + Mg(NO3)2 into the soil + Cd, 6) N + Mg(NO3)2 foliar dressing + Cd. The level of magnesium in plants in the DC 41 stage (stem elongation growth) increased in the magnesium-fertilised variants. The level of Cd in plants grown in soil with a natural Cd content increased in all the Mg-fertilised variants to 0.29--0.45 mg Cd . kg--1 compared with 0.27 mg Cd . kg --1 in the control variant. Of the plants grown in
