ABSTRACT:
In two seasons field trials, during 1998/1999 and 1999/2000 winter seasons three polygerm sugarbeet varieties namely, Pamela, Pleno and Samba were cultivated in sand clay loam soils of Nubaria region. Sugarbeet seeds were inoculated with the commercial biofertilizer HALEX in the presence or absence of ammonium nitrate. Sugarbeet seed biofertilization and /or N-fertilization significantly increased the root, top and sugar yields (Mg ha-1). Combination of inoculation and mineral nitrogen fertilization treatment , generally gave a positive response , the highest increase of root, top and sugar yields were 11.94, 12.90 and 18.46 % (Mg ha-1) with Pamela; 13.66,15.96 and 20.69 % (Mg ha-1) with Pleno, and 14.54, 15.34 and 22.03 % (Mg ha-1) with Samba varieties, respectively. Biological and/or nitrogen fertilization had slightly positive effect on both sucrose and purity percentages, but tend to decrease total soluble solids percentage (TSS%). Pamela, Pleno and Samba varieties were proved to be the most appropriate to cultivate under local environment. Statistical comparison of nitrogen applications for Samba variety indicate that the net returns were 3.45, 2.81 and 2.78 L.E/1L.E with the application of Halex, 144 Kg N ha-1 and 72 Kg N ha-1, respectively.
