The aim of this study was to evaluate the potential effects of biological fertilizer (BF) and biochar (BC) application on flowering and morphophysiological charachteristics of Narcissus. A factorial experiment based on a completely randomized design was conducted in12 treatments with three replications. The BC was applied by mixing dry soil at three levels (0, 2 and 4%w/w), whereas the BF was used at four levels (0, 20and 40 g Kg-1  mycorrhizal fungi(MF) and Nitrozist biofertilizer). The MF was used in direct contact with the underside of bulbs and bulbs were dipped in Nitrozist biofertilizer solution for 5 minutes. According to the results the highest fresh weight of flower, number of flowers, flower diameter, flowering stem diameter, height, leaf fresh weight, chlorophyll a, b and total leaf and potassium uptake were obtained in the combined treatment of 2%biochar by 40 g Kg-1 MF. Generally, in the most of studied traits, alone use of BF and BC improved the growth and flowering characteristics of plant compared to the control. However, the best results were obtained in the combined treatment of 2%BC and 40 g Kg-1 of MF, while by increasing the levels of BC and BF in combination with 4%BC and BF the desiered results were not obtained.

Narcissus is a bulbous plant in the Amaryllidaceae family. The aim of the present study was to investigate the effect of biological fertilizers and biochar on morphological and physiological properties of Narcissus cv. ‘Shahla’ (Narcissus tazetta L. cv. ‘Shahla’). The experiment was carried out in a factorial arrangement with a completely randomized design in a greenhouse at Ardakan University, in 2019-2020. The biochar was applied by mixing dry soil at three levels (0, 2 and 4 %w/w), whereas the biofertilizer was used at four levels: without amendment (control), 20 and 40 g kg-1  mycorrhizal fungi (MF) and Nitrozist biofertilizer (that bulbs were dipped in Nitrozist biofertilizer solution for 5 minutes). Results showed that a higher value for diameter of the largest flower (36.73 mm), diameter of sepal (10.53 mm), flowering stem (26 mm), number of leaves (8.66), width of leaf (20.44 cm), dry weight of root (3.18 g/pot), bulb diameter (1.66 mm), caretenoeid (2.22 mg g-1), chlorophyll (98.05 SPAD), calcium (3.83%) and phosphorus (0.96%) concentrations were obtained in combination of 2% biochar and 40 g per pot mycorrhizal fungi. For most studied traits, the use of biofertilizer and biochar alone improved the growth and flowering characteristics of plant compared to the control. However, the best results were obtained in the combined treatment of 2% biochar and 40 g kg-1 of mycorrhizal fungi, while by increasing levels of biochar and biofertilizer in the combined treatments the desired results were not obtained.

Azolla grows well in wetlands and reservoirs in northern Iran. This plant can be used as a source of compost and as an organic fertilizer. In this study, azolla compost (AZC) and humic acid (HA) were used in the production of daffodil. The experiment was carried out with factorial arrangement based on the completely randomized design. The first factor was AZC (25%, 50%, 75% and 100 %v/v) and the second factor was humic acid (0, 250 and 500 mg L-1). Results showed that the longest flowering stem with 24.03% increase compared to control, was recorded at 25% AZC + 500 mg L-1 HA. Treatments 100% AZC + 250 and 500 mg L-1 HA, produced the highest flowering stem diameter. Maximum anthocyanin content obtained in compost 100% + 250 mg L-1 humic acid. In compost 25% + 500 mg L-1 humic acid, the amount of nitrogen and calcium was at the maximum. In compost 75% + 500 mg L-1 humic acid, the concentration of phosphorus and potassium increased compared to the control. The results of the present study showed that the use of azolla compost and humic acid is effective in improving the quantitative and qualitative traits of daffodil.

Chemical components of Narcissus (Narcissus tazetta L.) essential oil investigated under farming and natural habitat conditions in South Khorasan province. The essential oil was obtained using solvent extraction method. After purification, the oil was analyzed by capillary GC and GC/MS. 12 compnents making 82/82% of total oil in farm sample and 13 components making 63/86% of total oil in natural habitat sample were identified. The main constituents were dodecane (%25/30) in farm sample and (28/29%) in natural habitat, Tetradecane (25/80%) in farming sample, (35/05%) in natural habitat sample. The type and amount of components, specially those with little amount showed differences in two conditions.
