Effect of N-fertilization, previous crop and soil salinity on growth, yield and quality of sugar beet in Kafr El-Sheikh governorate soils-survey study [electronic resource].

Includes references.

Field experiments were conducted under field conditions in 24 locations representing 8 districts at Kafr El-Sheikh Governorate in 2001/2002 season to study the effect of three previous crops (Rice, cotton and melon); two rates of N-fertilization (90 and 120 kg N/fed.) and soil salinity (three soil salinity levels; i.e. low: ECe = 1.47-4.0 dS/m; moderate: ECe =4.99-7.71 dS./m and High: ECe = 9.02-12.7 dS/m on yield and quality of sugar beet plant. The most important results are summarized as follows: • Increasing application rates of nitrogen significantly increased sugar yield and root length and decreased both of sucrose and sugar purity percentages. • Increasing soil salinity leaded to significant decrease most of growth and yield characters of sugar beet, except sucrose and sugar purity percentages were significantly increased. • Preceding crops had no significant effect on all yield and quality characters of sugar beet.
