Abstract

This study was carried out in the Experimental Farm of Faculty ofAgriculture, Cairo University, Egypt during two successive seasons 2004,2005 to investigate the effect of chemicals, yeast and biofertilization onvegetative growth of turmeric (Curcuma domestica Val.) plant.One level of the following bacterial strains mixture was used:Azotobacter chroococcum, Azospirillum lipoferum, Bacillus polymixa,Bacillus megatherium and Pseudomonas fluorescence. Also one level(6g/litre) of active dry yeast (Saccharomyces cerevisiae), in addition tothree levels from the recommended dose (zero, 50% and 75%) of nitrogenand phosphorus (120 N kg/hectar and 60 P2O5 kg/hectar) were applied.The results of these experiments can be summarized as follows:The treatment of biofertilizer + 75% of the recommended dose of bothnitrogen and phosphorus fertilizer led to the highest values of vegetativeparameters such as (plant height, stem diameter and leaf area) compared tocontrol plants. Also, it increased rhizome fresh and dry weight per plantand per feddan) compared to using active dry yeast + the same treatment ofchemical fertilizers or using chemical fertilizers alone.
