This study was carried out at the Experimental Farm of the South Tahrir Station of HorticuUure during the two successive seasons of 2003/3004 and 200412005 to investigate the influence of commercial. biofertilizers. organic manure, nitrogen and phosphorus minerals fertilizer on the growth and yield of potato cv. Mondial. Results show that all used commercial biofertilizers treatments combination with 50% nitrogen. phosphorus plus 50% chicken manure of added dose increased all parameters of vegetable growth and produced yield i.e, plant height. number of main stems. fresh and dry weight of plant foliage and tuber yield with significant differences in most cases. In addition, the different tested biofertilizers significantly increased both total carbohydrates and nitrogen contents while phosphorus was not affected during both seasons of study in leaves and tubers. In tltis respect. the best results of all studies vegetative growth, yield and chemical traits in the two seasons were obtained from the treatments of 50% N. P + 50% chicken manure + (EM) + (BY) followed by 100% chicken manure + (BY) and 50% N. P + 50% chicken manure + (EM) + (BM).
