Two field experiments were carried out during the two successive seasons of 1999 and 2000 at the Experimental Station of National Research Centre, at Shalakan Kalubia Governorate) to study the effect of different sources of organic manure (cattle and chicken manures) and chemical fertilizers (NPK) with or without biofertilizer (microbein) on growth, yield of eggplant and its some physical and chemical properties.  The important obtained data are following: 1-     Application of microbein biofertilizer resulted the highest values of growth characters, yield and its components, TSS and the contents of nutritional elements compared with the control treatment.   2- Addition of the chemical fertilizer (NPK) obtained the best vegetative growth characters, the heaviest yield (early and total as ton/fed.), the highest values of TSS, total protein as well as the concentration of N, P, K, Fe, Mn, Zn and Cu. 3- The best growth characters, heaviest yield (early and total as ton/fed.), average weight of fruits as well as the highest values of TSS, protein and the concentration of N, P, K, Fe, Mn, Zn and Cu all of them were resulted from that plants received with microbein biofertilizer and chemical fertilizer (NPK).
