Abstract
This experiment was conducted in the plastic greenhouse belong to the nursery of Duhok University for the period from 1st Oct. 2021 to 30th April 2022. With the aim of knowing the effect of three factors, the first factor is balanced Nano fertilizer NPK (20, 20, 20) in concentration (0, 3, 6) g L-1, the second factors is five growing media peatmoss, river soil, Kwashe compost, (River soil + Kwashe compost), (River soil + Kwashe compost + peatmoss) and the third factors pinching (without pinching) on the some quantitative and the quality indicators of (Pelargonium graveolens) plant. The results showed that the 6 g L-1 of Nano-fertilizer lead to a significant increase in the plant highest, branches number leave area, relative chlorophyll, volatile % and dry vegetative weight. The peat moss treatment and the combination treatment of river soil + kawachi compost + peat moss were significantly superior, giving the highest values in most of the studied traits. The pinching treatment caused a significant effect on the number of branches, leaf area, relative chlorophyll, percentage of volatile oil, and dry weight of the shoots, compared to the treatment without the pinching.
