Soil salinity adversely affects the growth, yield, and quality parameters of sugar beet, leading to a reduction in root and sugar yields. Improving the physical and chemical properties of salt‐affected soils is essential for sustainable cultivation and sugar beet production. A field experiment was conducted at t the Delta Sugar Company Research Farm, El‐Hamool, Kafr El‐ Sheikh, Egypt to evaluate the response of sugar beet to the application of beet sugar filter cake treated with sulfuric and phosphoric acid‐treated, phosphogypsum (PG), desaline, humic acid and molasses under saline soil conditions. The application of treated filter cake enhanced root length, diameter and leaf area. The application of molasses enhanced root length, diameter and leaf area as well. Application of molasses increased sugar content and root yield. The application of either treated filter cake or molasses produced the highest recoverable sugar yield. Linear regression analysis revealed that the root yield, quality index and recoverable sugar yield increased in response to the increased availability of either Ca2+ and K content in the soil which increases in response to the application of soil amendments and molasses. The application of treated beet sugar filter cake and molasses increased the calcium, magnesium and potassium availability in the soil. Treated filter cake is a promising organic soil amendment that enhanced the yield by 29%, and yield‐related traits of sugar beet by improving the physical and chemical properties of the soil.

甜菜糖副产物提高了盐渍土壤中甜菜的产量和盐分的分布

土壤盐分会对甜菜的生长,产量和质量参数产生不利影响,导致根和糖产量下降。改善受盐影响的土壤的物理和化学特性对于可持续种植和甜菜生产至关重要。在埃及Kafr El Sheikh的El-Hamool的Delta Sugar Company Research Farm进行了田间试验,以评估甜菜对应用硫酸和磷酸处理的磷酸石膏处理的甜菜糖滤饼的响应( PG),去盐碱,腐殖酸和糖蜜在盐渍土壤条件下。处理后的滤饼的施用增加了根的长度,直径和叶面积。糖蜜的应用也增加了根的长度,直径和叶面积。糖蜜的应用增加了糖含量和根产量。处理过的滤饼或糖蜜的施用可产生最高的可回收糖产量。线性回归分析表明,根系产量,品质指数和可回收糖产量都随着Ca利用率的增加而增加。土壤中2+和K的含量随着土壤改良剂和糖蜜的应用而增加。处理甜菜糖滤饼和糖蜜的应用增加了土壤中钙,镁和钾的利用率。经过处理的滤饼是一种很有前途的有机土壤改良剂,可通过改善土壤的物理和化学特性,使甜菜的产量提高29%,并提高甜菜的产量相关性状。
