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. Geraniol, Cineole. Unalyl acetate and Citroneuol). In addition, lhesignificant InClEJ.a$eSWefe 15.B, 19.9 and 14.4%fol herb Ire-shweight (g/plant) and 198, 16.9 and 14.7% for herb dry weight [g/planl) in first. second and third cuttings, respecilvety. as well as essential oil percentage (25 % .25% and 28 % in the three curtmgs. rescecuvely ) and 011 yleld/DIMI ( 44 %. 52% and 47 % in the three cuMings. respectJvety ) In fresh herb al the highest compost level as compared La lhe conuot ueatrnent Also marjoram plants wtlich received lhe highest tevel of compost in combination with blolertili2er mixture siQI1ificanily surpassed the control plants in herb fresh waight (g/ptant) by 22. 1 29.' and 32.' % and herb dry weight (g/planl) by 25, 32.6 and .\.{)% in first.

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.
