Název v původním jazyce

Split nitrogen doses and their efficiency in poppy (Papaver somniferum L.) nutrition

Popis výsledku v původním jazyce

The efficiency of partial doses of nitrogen applied to poppy (Papaver somniferum L.) plants, cv. Opál, was followed in a pot experiment. The ammonium nitrate was applied either in a single dose at the beginning of growing season or in two split doses with the second application in the stage of flowering. With the increasing dose of nitrogen the number of capsules per a plant during the harvest and their volume increased irregularly. The separated application of an optimum dose of N (i. e. 0.9 g N per pot) showed a statistically highly significant positive effect on the yield of poppy seeds compared to the same single dose of N this figure was increased by 25.6 %. The morphine content in capsules increased with the increasing supply of N from 0.85% to 1.01%. The term of nitrogen application influenced the number of capsules per a plant and their volume and morphine content irregularly.
