Catastrophic changes in the earth brought on by dwindling annual precipitation and rising temperatures eventually lead to the salinization of the soil. These circumstances result in decreased yield production, which moves the globe closer to food security. The goal of the present study was to clarify the impact of sugar beet extract (SBE) as a bio-stimulant to lessen the salt stress (40 mM) on several physiological and biochemical parameters of barley. Seeds of Hordeum vulgare L. (Barley-13 genotype) were pre-soaked in various concentrations (10, 20, 30, 40, and 50%) of SBE for five hours. SBE was analyzed for glycine betaine, betalains, total phenols, flavonoids, vitamin E, vitamin C, sugar, protein and oxalic recorded 100 mmol/kg, 1.36 mg/L, 1.30 g/100 ml, 0.59 mg/ml, 0.002%, 8.04g/100 ml, 8 g/100 ml, 1.39 mg/100 ml and 38 mg/100 ml respectively, along with elemental composition. Significant improvement were observed in morpho-physiological attributes including stomatal and epidermal physiology along with agronomic parameters including germination energy (GE), mean emergence time (MET), coefficient of velocity of germination (CVG), germination rate index (GRI) and timson germination index (TGI) time to 50% emergence (T₅₀) during exposure to salinity stress. Physio-biochemical parameters including chlorophyll and carotenoid contents were found maximum in 40% SBE, soluble sugar, protein, proline, and peroxidase (POD) were maximum in 50% SBE, while superoxide dismutase (SOD) were maximum in 20% SBE. Conclusively, SBE play a significant role in the development and promotion of agronomic and physiological attributes of barley and thereby boost crop output in arid, semi-arid, and salty environments, which will benefit global economy.

年降水量减少和气温升高导致地球发生灾难性变化，最终导致土壤盐碱化。这些情况导致产量下降，使全球更接近粮食安全。本研究的目的是阐明甜菜提取物 (SBE) 作为生物刺激剂对减轻盐胁迫 (40 mM) 对大麦的几种生理和生化参数的影响。大麦种子 L.（大麦 13 基因型）在不同浓度（10%、20%、30%、40% 和 50%）的 SBE 中预浸泡 5 小时。SBE 分析甘氨酸甜菜碱、甜菜碱、总酚、类黄酮、维生素 E、维生素 C、糖、蛋白质和草酸记录为 100 mmol/kg、1.36 mg/L、1.30 g/100 ml、0.59 mg/ml、0.002%，分别为 8.04 克/100 毫升、8 克/100 毫升、1.39 毫克/100 毫升和 38 毫克/100 毫升，以及元素组成。观察到气孔和表皮生理学等形态生理属性以及发芽能 (GE)、平均出苗时间 (MET)、发芽速度系数 (CVG)、发芽率指数 (GRI) 和 timson 发芽率等农艺参数的显着改善指数 (TGI) 时间到 50% 出现 (T ₅₀）在暴露于盐度胁迫期间。叶绿素和类胡萝卜素等生理生化参数在40% SBE中含量最高，可溶性糖、蛋白质、脯氨酸和过氧化物酶（POD）在50% SBE中含量最高，超氧化物歧化酶（SOD）在20% SBE中含量最高。总之，SBE在开发和促进大麦农艺和生理特性方面发挥着重要作用，从而提高干旱、半干旱和盐碱环境下的作物产量，这将有利于全球经济。
