The present study was carried out at Shandaweel Agricultural Research Station (Souhag Govemorate) for two successive seasons of 2001/2002 and 2002/2003. Each trail induded 18 treatments represent the combination between two plant densities (one and half drills of three budded sugar cane cuttings "37800 buds/fed. and double drills 50400 buds/fed), nine fertilizer treatments and mineral: (inoculation with Azogfrialum only, 180 kg N/fed and inoculation with Azospifillum + 90 kg N/fed) and (zero application phosphours, 200 kg superphosphate calcium (15.5% P20_s/fed) and inoculation with Phovhobactedn). (The commercial sugarcane variety viz. G.T.54-9 was used in the study. Experimental treatment were arranged in a split split plot design with four replications. Plant density were allocated in the main plots while nitrogen fertilizer levels were assigned to the sub .plots and Phosphour treatments were randomely distributed in the sub-sub plots. The results showed that double drills surpassed 1.5 drills in number of plants/m², elongation rate (an/day), stalk diameter (an) and reducing sugar, purity and sugar recovery percentages. Azospinllum + 90 kg N/fed treatment increased number of plants/m², elongation rate (cm/day), stalk length (cm) and reducing sugar, brix, purity percentages, number of minable cane (thousand/fed), cane and sugar yield (tons/fed) over other treatments. While 180 kg N/fed surpassed the other treatments in stalk diameter, leaf area and sugar recovery percentage. Phosphours fertilizer 200 kg as superphosphate calcium (15.5% P₂0_s/fed) increased numbre of plants/m² and stalk length in the la season and number of minable cane (thousand/fed), cane and sugar yield (tons/fed). While inoculation with Phosphobactenn surpassed other treatments in elongation rate (cm/day) in both seasons and stalk length in the 1" season only.
