Abstract EN

The experiment was carried out in Taiba Research Station during the season 2018/2019, 2019/2020 in order to investigate the effect of foliar application of licorice extract and dry yeast on the growth and productivity of the kiswani garlic cultivar.

Extracts were foliar applied in 4 concentrations (2.5,5,7.5 and 10 g .L-1) and with 5 spray times during the season from both extracts.

Distilled water was used for control treatment.

The experiment was designed according to the completely randomized blocks design with four replications.

The results indicated that significant superiority of treated plants with root licorice root extract concentration 10 g L1 in the height of its plants, leaf length and width, the number of leaves on the plant were (99,00cm, 56.25 cm, 2.20 cm, 7.90 leaf/plant, respectively) and the differences were not significant in the trait of leaf length, diameter and number of leaves in the spray treatment with yeast extract concentration 10 g L1 were (54.00 cm, 2.13 cm, 7.78 leaf plant'1 respectively), the positive effect of natural extracts on vegetative growth indicators contributed to improving productivity of indicators, especially the treatment of licorice spray 10 g L1 which significantly superiority in the indicators of average bulb weight, bulb diameter, number of bullbats, productivity and percentage of dry matter were (90.02 gm, 5.30 cm, 21.70 bullbats, 1400 gm rrr2, 41.39% respectively) and the differences were not significant with the spray treatment with yeast extract with the same concentration.
