“…Salinity can affect plant physiological processes resulting in reduced growth and yield . During the course of salinity stress, active solute accumulation of osmotic solutes such as soluble carbohydrates, proteins and free amino acids is claimed to be an effective stress tolerance mechanism (Dawood et al 2014a;Talaat et al 2015;Sadak et al 2015). The adaptability of plant species to high salt concentrations in soil by lowering the tissue osmotic potential was accompanied by the accumulation of these osmotic solutes (Jaleel et al 2008).…”

“…Different studies have depicted the dramatic decline in potassium concentration under salinity stress (Abbasi et al, 2014;2015 a) along with strong positive association of shoot K + concentration and plant for salt tolerance (Chen et al, 2005). Moreover, ability of roots to retain more potassium has also been verified as one of the key factors deliberating the salt tolerance in wheat (Cuin et al, 2011), maize (Abbasi et al, 2014), barley (Chen et al, 2005;, bean (Dawood et al, 2014) and lucerne (Smethurst et al, 2008). The application of potassium fertilizers under saline conditions has results in improvement of plant growth (Abbasi et al, 2015 b).…”

“…Salinity stress reduces relative growth rate, net photosynthetic rate, net assimilation rate and alters biomass production (Akram et al, 2011;Sun et al, 2011). Kabir et al (2004) reported that salinity reduced total dry matter of plants which ultimately caused reduction in crop yield but application of potassium improved growth and biomass yield of barley and bean under saline conditions (Mahmood, 2011;Dawood et al, 2014). Potassium was applied at the rates of 0, 40, 80 and 120 kg ha -1 .…”

Salinity is an agro-environmental problem limiting plant growth and development in the arid to semi-arid regions of the world and becomes the predicament of serious concern. Plants exposed to salt stress may undergo osmotic stress, ion toxicity and nutritional imbalance which results in production of reactive oxygen species (ROS). The ability of plants to detoxify radicals under conditions of salt stress is probably the most critical requirement and is determined by multifarious morpho-physiological and biochemical pathways like initial entry of salt to roots, intercellular compartmentation, synthesis of osmoprotectants (sugars, amino acids, proline and upgradation of antioxidant system) that results in maintaining ion homeostasis. This paper also revealed the plant responses to salinity stress with emphasis on physiological and biochemical mechanisms of salt tolerance which may help in interdisciplinary studies to assess the ecological consequence of salt stress. Moreover, the application of potassium helps the plants to cope with the hazardous effects of salinity by improving the morphological, physiological and biochemical attributes.

Salinity is a major impediment to crop production. This study was undertaken to compare the effect of seaweed extract, humic acid, and potassium sulfate nanoparticles in alleviating salt stress in Alfalfa (Medicago sativa L.). Seeds of ten alfalfa genotypes were germinated in a growth chamber at five salt concentrations (0%, 0.5%, 1.0%, 1.5%, and 2.00%). Salt concentrations above 1% reduced seed germination by more than 70% in most genotypes. One salt tolerant genotype (Mesa-Sirsa) and one salt sensitive (Bulldog 505) were selected and planted in greenhouse pots containing 2 kg of sand and subjected to two salt levels (10 and 15 dS·m . Plant biomass was reduced under both salt concentrations in both genotypes, with a greater magnitude in the salt sensitive genotype. Application of seaweed extract resulted in higher relative water content and proline under both salt concentrations (10 and 15 dS·m −1 ) in the salt sensitive genotype, and lower electrolyte leakage in both salt tolerant and salt sensitive genotypes, under both salt concentrations. Seaweed extract also resulted in higher catalase and SOD activities in both genotypes under 10 dS·m −1 . Catalase and SOD activities were associated with significantly (p < 0.01) reduced electrolyte leakage and increased shoot dry weight. Overall, seaweed extract seemed to have a positive effect in alleviating salt stress in alfalfa.
