Physio-biochemical and Agronomic Changes of Two Sugar Beet Cultivars Grown in Saline Soil as Influenced by Potassium Fertilizer

Abstract In salt-affected soils, more than one approach should be adopted for minimizing the salinity impacts and enhancing land productivity. The most effective practices in crop management under saline soil are choosing plant type variety exploiting best nutrient tactics. Under two levels (3.54 9.28 dS m ?1 ), representing low high salinity, respectively), sugar beet cultivars (Romulus Francesca) were fertilized with three potassium (K) rates (48, 96, 144 kg K ha addition to check treatment (0 ). During seasons of 2018/2019 2019/2020, treatments distributed a split-split plot design based on randomized complete block arrangement replicates. Several physio-biochemical agronomic traits, as well leaf mineral contents juice quality, assessed. Briefly, findings illustrated that at rate enhanced cell membrane stability, relative water content, performance index by 1.17, 1.01, 2.73 times, respectively, soil, compared × no addition. 48 recorded highest values total phenolic content antioxidant activity, respectively. supplying (144 ) caused maximum improvements gross white decrease 42.0% sodium an increase 35.9% root yield . Romulus cultivar had F v /F , index. Francesca was potent combination increasing soluble sugars, flavonoid activity. practice improving all traits beet. It could concluded rate, i.e., reduced injury ionic soils along genetic makeup cultivars, expressed quality. However, other attempts reclamation potentiality fertilizer gene expressions different varieties.
