Abstract
Two pol experiments were carried Qui during two successive seasons 2000 arid 2001 to inlJBstigale ths effecl or organic fertilizer (8iogreen) at Ii1ree rates: 5, 10 and 15 m)!1ed. wllh or wilhovt biofer1illzar i(l()culation (namely: AzobaC1er crococcum; Atoscuitiur» bresltease and Beduus polymY:V8) it1 comparison wilh lhe recommended dose or NPK (control) on growtn. yield and chemical cornpo sition o( marjoram pfants. Data obtained dearly revealed lhat plants treated with the highe:it revet of compost (15 m1I fed.) euher alone o( Inoculated with mixture or biolerjjllzers recorded a considerable increments with regard to growth characters. rnacronutrients. phytohormone!!: (IAA, GAl, and CK) and essential all components: ( a-terpineol. 0- terpenolens, Lnaloot.

On Ihe othe1' hand. the present data disclosed that nearly lhe same mariorarn fresh and dry weighl (g/plant) as well as essentlal oil percentage and 011 yield per plant of the coouol planl could be obtained if marjoram plants received the lowest arid madera Ie rates of compost fertilizer alone or combined wilh biofertilizers mixture. These fIndings clearly Indicate that organic fertilizers (8iogreeo) and biofertilizers mixture could replace the application of mineral fertJlizers and consequently minimize ine pollution 01 Ihe a9 ncultural environment.
