Cím:The changes of the purple coneflower's (Echinacea purpurea L.) herba and radix drug yield under different fertilization settings / Lelesz Judit Éva, Csajbók József
Dátum:2018
Megjegyzések:The experiment took place in the experiment site of the University of Debrecen. Plot size was 8 m2, arranged in 4 replicates in randomized blocks, with 6 different fertilizer treatment levels. The experimental place's soil is chernozem. The forecrops were potato and sunflower.The fertilizer doses were from N 15 kg ha-1, P2O5 20 kg ha-1 and K2O 30 kg ha-1 to N 75 kg ha-1, P2O5 100 kg ha-1 and K2O 150 kg ha-1 in 5 levels with 15 kg ha-1 N, 20 kg ha-1 P2O5, and 30 kg ha-1 K2O steps.We measured the raw and the dry mass of the herb and the three years old roots, we picked up 7th and 8th November in 2017. We dried the herb under prenumbra for three weeks in 2016. In 2017 because of the rainy weather, we used drying cabinet on 40 oC for 72 hours and the roots for 48 hours. During processing of the data, variance analysis were applied by using MS Excel 2010 and IBM SPSS 22.0 programmes.Every fertilization settings has a negative effect on the raw and the dry herb mass in 2016, and a positive in 2017. As for the roots' yield fluctuations were observed. Until now we could not found an explanation for this phenomenons. The variance analysis of the data did not show significant differences between the different fertilizer settings. More research work needed to clear up the complex connections between quantity of the drugs' mass, and the effect of the different nutrient settings.
