Abstract: Two field experiments were conducted during 2014/15 and2015/16 seasons to study the effect of three mineral nitrogen fertilizer levelsi.e., 60, 90 and 120 kg N/fed and four biofertilization (withoutbiofertilization, rhizobactrein, phosphorein and dual inoculation) and threefoliar spraying levels with humic acid (water as a control, 12 and 24 g/l) onyield and its attributes of sugar beet variety Kawemira. The experimentaldesign was a split-split plot in RCBD with three replications where mineralnitrogen fertilizer, biofertilization and foliar spraying with humic acid wereallocated in the main, sub and sub-sub plots, respectively.Results indicated that mineral nitrogen fertilizer andbiofertilization with foliar spraying with humic acid had significant positiveeffect on yield, yield components and quality traits. The heaviest root freshweight (2.17 kg/plant), root yield (39.77 t/fed) and gross sugar yield (7.13t/fed) (fed= feddan= 4200 m2) were obtained by the highest level of mineralnitrogen fertilizer (120 kg N/fed), with application the mixture ofrhizobactrein+ phosphorein as biofertilization with the highest concentrationof foliar sprayed with humic acid (24 g/l).The results of regression analysis of yield and its attributesclarified that, there were four traits i.e. sucrose %, root yield, root length androot fresh weight in the first season, while in the second season, the sametraits except root length were significantly (P ≤ 0.001) contributed tovariation in gross sugar yield.
