Studies on Nitrogen Fertilization and Gibberell in on The Growth and Oil Production in Ruta Graveolens L

In Egypt the Plant had not attention concerning the agriculture treatments wich affect its productivity there for this study was conducted to investigate, the effect of nitrogen sources,GA3 treatments and their interation on the vegetative growth of plants and active ingredient.the seeds were sown in nursury on october 16th for both two seasons.
