In this project, Lavander species was identified by with study of morphological characteristics and flora of Phalastina,Turkey and Iranica,This species has recognized with scientific names of Lavandula officinalis, Lavandula vera, Lavandula aungustifolia. Studies have shown that origin of Lavander is Europea conteries, such as France and it was spred via florance and Venis fo different parts of the world. The best way to increased this plants are with grafts to longitiuate 5-8 Cm from plant 2-3 ages.In this project enough a number of 500 Lavander grafts prepared to up way. Using Auxin 5ppm for part grafts for 24 hours,which usin from Auxin took the root two weeks earlier ratio to witness group,After three month growth and control of Lavander grafts in green house, transvered to farm.The farm divided in compelet block random design and applied amount 0,50,100,150,200 kg per hectar ammonium nitrate in tree period to space two month,The farm irrigated with drop system, After five month took away ten plants in each part recorded heigh and plants canopy diameter, Plants cut with a pair of scissors. Average fresh weight, dry weight of ten plants in each part recorded after dispersed in green house.Extraction essential oil of dry plant with Clevenger.Analysis data in end of project with soft wares of computer. Result showed ammonium nitrate caused an increase in fresh weight, dry weight, height, plants canopy diameter, number of branches and essential oil. Plants products increased with increase ammonium nitrate. The high growth showed in 150-200 kg per hectar Ammonium nitrate caused to high growth. Although nitrogen didn,t effective directory on medicinal compound, But nitrate present in Chlorophyl moleucol, However presentation of nitrate cause spreaded of leaves and level to build increased compond hydrocabones.

Effects of six levels of nitrogenous fertilizers (urea) on yield and total alkaloids content in different Organs of Physalis alkekengi were investigated. All experiments were performed at Medicinal Plants Research Station a branch of Yazd Province Research Center for Natural Resources and Animal Husbandary. Experiments were designed as a completely randomized blocks. Six levels of urea fertilizer namely, 0,50,100,150,200 and 250 kg/ha with three replicates were applied to the soil. Upto a certain level, there was a positive correlation between the amount of Napplied and the plants yield (leaves, stems and roots). The correlation between urea application and plants canopy and height was also positive. Whereas the highest plant yield was obtained with 150 kg urea/ha the maximum plant height was achieved with the application of 100 kg urea/ha. Any increase in the amount of N-fertilizer beyond 150 kg/ha had an adverse effect on plant yields. The total alkaloids content in leaves, fruits and roots were determined by Yanevan method. Increasing the amount of urea resulted in an increase in total alkaloid content of leaves, fruits and roots. Application of urea at a rate of 100, 150 and 200 kg/ha caused the highest increase in total alkaloids. Since there was no significant difference (@= 0/01) among the means of alkaloids produced in these treatments, it was concluded that the highest alkaloids will be obtained by application of urea at a rate of 150 kg/ha. Increasing the amount of urea did not affect the rate of root expansion significantly. However, root depth decreased in response to urea application. The highest root depth was obtained in control (no urea) plants. This is in agreement that N-Fertilizers will mostly increase the amount of shoot rather than root system.
