Split Application of Nitrogen in the Poppy (Papaver somniferum, L.) Nutrition

Original language description

Efficiency of partial doses of nitrogen in different growth stages applied to poppy (Papaver somniferum L.) plants, cv. Opál, was investigated in a pot experiment. Nitrogen was applied either in a single dose at the beginning of growing season in doses of 0.6 and 0.9 g N per a pot or in two split doses in the total amount of 0.9 g N per a pot as ammonium nitrate. In these variants, the dose of 0.3 g N (1/3 of whole dose) was applied either in the stage of leaf rosette (DC 35) or stem elongation growth (DC 41) or flowering (DC 49). After harvest, the following parameters were evaluated: number of poppy capsules per a plant and their volume, yield of seeds and percent of morphine in capsules produced for pharmaceutical industry (i. e. in empty capsules with 15 cm of stems). With increase of nitrogen fertilization from 0.6 to 0.9 g N per pot applied at the beginning of growing season poppy yield increased not significantly. The split application of the higher dose (0.9 g N per pot) in com
