Tolerance of some sugar beet cultivars to soil salinity [electronic resource].

Includes references.

Two field experiment were conducted at the experimental farm of Sakha Agric. Res Station during two successive seasons 1996/97 and 1997/98. The objective of this investigation was to study the effect of four ranges of Soil salinity; 8-12, 12-16, 16-20 and 20-25 dS/m under field conditions, on yield and quality of four sugar beet varieties; Ras Poly, Kawemira, Maribo and Dobreah local (Syrian cultivar). The experiments were conducted in split-plot design with four replicates. The obtained results can be summarized as follows: • The root yield of sugar beet cultivars was affected significantly by the different ranges of soil salinity. -The highest values of root yield in the two seasons were generally obtained from Dobreah local (Syrian cultivar) under all soil salinity ranges. *Sucrose percentage of sugar beet cultivars were significantly affected by soil salinity ranges in the first season. Sucrose percentage was significantly affected with sugar beet cultivars in both seasons.
