Název v původním jazyce

POTASSIUM SULPHATE AND POTASSIUM CHLORIDE IN THE NUTRITION OF POPPY (PAPAVER SOMNIFERUM, L.) IN RELATION TO NITROGEN SUPPLY

Popis výsledku v původním jazyce

A pot trial was carried out to study the effect of varied K and N nutrition on seed yields and concentration of the alkaloid morphine in the straw of poppy (Papaver somniferum L. var. Buddha) grown in soil low in available potassium. Both K and N were supplied to the pots which contained 9.5 kg soil, at two levels, (K1, K2 and N1, N2), K in the form of K2SO4 (SOP) or KCl (MOP) and N in the form of ammonium nitrate (NH4NO3). Potassium was applied at rates of 0.845 (K1) and 1.69 g K2O per pot (K2), equivalent to 56 and 112 kg K2O/ha, and nitrogen at 0.9 (N1) and 1.5 g N per pot (N2), equivalent to 60 and 100 kg N/ha respectively. The relative effectiveness of both potassium fertilizer sources in increasing seed yields was greater in treatments with the lower level of nitrogen supply (N1), but in terms of production, higher seed yields were obtained at the higher N supply (N2). At the lower level of N supply (N1), seed yields increased significantly after the application of SOP and MOP by
