(ALGAZON), Yeast, Vegetative, Volatile oil, Myrtus (Myrtus communis L.)


This study was conducted at the nursery of Agricultural Research Station, Agriculture College, University of Basrah, Qarmat Ali campus, at the agricultural season 2018-2019. The Experiment was conducted using Randomized Complete Block Design (R.C.B.D), with two factors, the First factor was organic fertilizer (ALGAZON) with three concentrations (0, 1.5 and 3) ml. L-1, the Second factor was dry yeast extract in three concentrations (0, 3 and 6) g. L-1, by five sprinkles one month between them and a five-day difference between the factors. The results showed that spraying with organic fertilizer (Algazon) at a concentration of 3 ml.L-1, led to a significant increase on the plant height, the main stem diameter, leaf area, main branches number, the fresh and dry weight of the leaves, the dry matter percentage of the leaves, the percentage of oil, the oil yield in the plant, the productivity of volatile per hectare, specific weight and the density of the oil. Sprinkle with dry yeast extract at 6 g. L-1, resulted a significant increase in all vegetative parameters studied and oil yield. The interaction between the organic fertilizers (ALGAZON) spraying treatments was 3 ml. L-1 and dry yeast extract 6 g. L-1, were a significant effect, led to an increase in plant height, the main stem diameter, leaf area, the branches number , Fresh and dry weight of the leaves and the percentage of dry matter, the percentage of oil, Yield oil in plant, productivity of volatile per hectare, refractive index, specific weight and the density of the oil.
