Abstract

In order to examine the effect of the quantity of Nitrogen fertilizer and bush density on vegetative and productive function of henna medicinal plant (Lawsonia inermis)  factorial experimentation in the form of block plan was carried in three stages in agriculture research center in south of kerman  province in corp of 2012. The first factor containing Nitrogen fertilizer in 4 levels including 50,100,150,200 kg net Nitrogen fertilizer and the second one as bush density in three level including 110000-160000-210000, bushes were examined. The measured traits included weight of fresh stem, stem, height weight of dried stem and leave, and total dried and fresh weight and all of productive traits including weight of fresh and dried flower, number fruits in bush, number of seeds in a fruit, number of seeds in frui weight of 1000 seeds and function of  seeds. The results indicate that that effect of bush density, nitrogen fertilizer qualities and contrast effect between two factor on weight of fresh and dried leave Statistically was in to concern up to 1%, but nitrogen fertilizer shows no difference in statistical respect on this quality, nitrogen fertilizer effect on all of productive qualities except number of seeds in fruit Was up to 5% fruitless as the main consumption of henna is its leaves. Finally with density of the bush 160000 to 210000 bushes in 1 hectare and consuming 50kg nitrogen fertilizer with function of dried leaves weight up to 3.54, 3.34 tons in one hectare is recommended. Even though consumption of 100kg nitrogen fertilizer in hektar resulting of maximum effect on dried weight.
