ABSTRACT:
In two seasons field trials, during 1998/1999 and 1999/2000 winter seasons three monogerm sugarbeet varieties namely Gala, Invermono and Maribo were planted in sandy clay loam soil of Nubaria region. Sugarbeet seeds were inoculated with the commercial biofertilizer HALEX in the presence or absence of ammonium nitrate. The results showed that sugarbeet seed biofertilization and /or N-fertilization significantly increased the yield traits i.e. root, top and sugar yields (Mg ha-1). Increasing nitrogen fertilizer from 0 to 144 kg N ha-1 caused significant increases in all yield traits i.e. root, top and sugar yields. Combination of inoculation and mineral nitrogen fertilization treatments (I+N2), generally gave a positive response , the highest increase of root, top and sugar yields were 45.74, 26.76 and 54.49 (Mg ha-1) with Gala; 46.50, 30.91 and 56.33 (Mg ha-1) with Invermono, and 56.55, 21.38 and 78.81 (Mg ha-1) with Maribo varieties, respectively. Biological and/or nitrogen fertilization had marked positive effect on both sucrose and purity percentages, and tend to decrease total soluble solids percentage (TSS%). Maribo was proved to be the most appropriate to cultivate under local environment, Gala came second and Invermono was not promising. Statistical comparison of nitrogen applications for Maribo variety indicate that the net returns were 4.11, 3.65 and 3.24 L.E/1L.E with the application of Halex, 144 Kg N ha-1 and 72 Kg N ha-1, respectively.
