Prof. Dr. Jamal Ahmed Abbass College of Agriculture, University of Kufa Prof. Dr. Jamal Ahmed Abbas.; The Effect of Nitrogenous and Phosphate Fertilizers of the Properties on the Vegetative Growth and Aromatical Oil Yield of Local Mint (Mentha Spicata L.), Am.-Eurasian J. Sustain. Agric., 3(2): 262-265, 2009 ABSTRACT A field experiment was carried out the season 2005-2006 in private farm in Najaf province to investigate 2 5 four mixture of nitrogenous and phosphate fertilizers i.e. (0, 100 kg N/ha, 150 kg P O /ha, and 100 kg N/ha 2 5 + 150 kg P O /ha) on vegetative growth properties and oil yield of local mint. A simple experiment was performed through Completely Randomized Design (C.R.D.) with three replicates. The mean results compared according to L.S.D. (Least significant Difference) with 5% probability level. The results showed that the nitrogenous and phosphate fertilizers has improved the vegetative growth properties (plant height, number of leaves and branches, vegetative yield (ton/ha) and total chlorophyll content in leaves). Oil yield increased 2 5 significantly compared with non-fertilized plants. So, the fertilized plant with (100 kg N/ha + 150 kg P O /ha) gave the highest parameters, since the plant height (64.26 cm), number of branches (8.36 branch/plant), vegetative yield (10.44 ton/ha) and total chlorophyll (7.01 mg/100 g fresh weight). In addition there is significant increase in oil yield to (53.72 kg/ha) as compared non-fertilized which gave the least vegetative parameters and less oil yield (46.71 kg/ha). The conclusion of this experiment is that using nitrogenous and phosphate fertilizers together have improved the vegetative growth, oil yield of the local mint plant. Key words: Mint, Phosphate fertilizers, Vegetative growth. Introduction After two centuries of continuous decline in the use of herbal medicines, Interest in them started again. Medicinal herbs, which were the final form of medicine in developing countries, have become used again in the developed world where people do their utmost to stay recuperating in challenging environmental pollution. And resort to consulting herbal medical specialist trainees (herbalists). Started widely used medicinal herbs that were used by parents and grandparents. Herbal drug sales rose in Europe and went to 10% in England and 35% in Spain (Hovalier, 2005). Mint plants are medicinal plants used by the task since the old time, as dried leaves are found in the Pyramids of Egypt (3000 BC). The Municipal mint (Mentha spicata L.)is one of the important species of Labiatae family in Iraq. The crop is used as necessary medical sedative of nerves, and useful in the treatment of asthma, bronchitis used to treat intestinal disorders and infectious live and renal colic and to prepare toothpaste (Hussein, 1981). Mint Included in the industry of perfume, soap and some food products such as sweets and biscuits (Abu Zeid, 1992). Mint is a green plant with a particular smell aromatic, perennial, with height of 30-155 cm. The green leaves is picked and dried in the shade, crushed, sifted and used until needed. The leaves contain aromatic oil with Menthol. Mint is used in salads to open appetite. Syrup made from mint has a good taste. The powdered dried mint is added to certain foods to exceed the flavor and alleviate the impact of acidity (Abu Zeid, 1992). Because of the importance of high medical mint and for the purpose of improving the growth of vegetation
