Abstract
The present work was conducted for two successive seasons, i.e. 1996 /1997 and 1997 /1998 at Shandaweel Research Station, Agricultural Research Centre, Sohag Governorate. The aim of the study is to investigate the effect of bicfertlizer on growth characters, chemical components, juice quality, yield and yield components of sugar cane varieties.The experiments included 18 treatments which were the combination between two sugar cane varieties (G.T.54-9 and G.85-37) and nine fertilization treatments: 180 kg N /fed.,120 kg N / fed., 60 kg N / fed., inoculation with Azotobacter +60 kg N /fed., or +120 kg / fed., inoculation with Azospirillum +60 kg/fed., inoculation with Azospirillumm +120 kg / fed., inoculation with Azotobacter only and inoculation with Azospirillum only. Azotobacter chrooccocum and Azospirillum brasilense were obtained from soil, water and environmental research institute, agricultural research center Giza. Exprimental treatments were arranged in complete randomized block design with four replications. A combined analysis for the two season was done. The important results could be summarized in the following: "-Sugar cane varieties had no significant effect on N % ,Na % , Brix and sucrose % , however, K % , purity % ,and sugar recovery were significantly affected by the examined varieties. The lower value of fiber % was recorded with the commercial variety "G.T.54-9". "-Application of biofertilizer sources i.e Azotobactor and Azospritlum with 120 kg.N/fed. improved N % and recorded the lowest value of K % and appropriate of fiber % . The highest value of sugar recovery (12.33 % and 12.23)was recorded by applying 180 kg.N /fed, inculated seed setts by Azotobacter chrooccocum + 60 kg.N /fed respectively, however, effect of nitrogen sources on Na % , K % , Brix %, Reducing sugar % , Sucrose % and purity was insignificant.
