The present study was carried out at the Experimental Farm of Fac. Agric., South Valley University, Qena Governorate, Egypt during the two successive seasons of 2004/2005 and 2005/2006. In loamy sand soil, Potato cv. "Diamant" was cultivated to study the effect of nitrogen fertilizer (37.5, 75, 112.5 kg N/fed.), biofertilizers (Azotobacter sp., Azospirillum sp. and mixture of both inoculants) and organic fertilizer at the rates of 10, 15 or 20 tons of compost/fed. on yield and quality of potato. The obtained result~ indicated that applying three fourth of the recommended dose of N+ Azotobacter sp. + 15 tons compost/fed. increased 'potato vegetative growth expressed as plant height, number of aerial stems/plant and dry weight of aerial stems/plant. Tubers dry matter percentage was increased with the combined application of onc fourth of the recommended dose of N/fed. + mixture of dual inoculants and 10 tons compost/ feddan.
