“…These toxic ions interfere with the normal physiological processes causing membrane damage, nutrient imbalance, altered levels of growth regulators, enzymatic inhibition and metabolic dysfunction, including photosynthesis which ultimately leads to plant death ( Mahajan and Tuteja, 2005 , Kumar et al, 2018a , Kumar et al, 2019 ). Thus the plant growth is impaired by osmotic stress in a first phase and ionic stress in second phase (accumulation of high concentrations of salts (toxic ions) within the plant which damages cell functions and structure) and finally suppress the yield ( Kumar et al, 2018b , Mann et al, 2019a ). These negative effects include interference of root function in absorbing water, as well as the prevention of physiological and biochemical processes such as uptake of nutrient like Ca ++ , Mg ++ and K + and their assimilation ( Carillo et al, 2011 ).…”

In the era of climate change, decreased precipitation and increased evapo-transpiration hampers the yield of several cereal crops along with the soil salinity and poor ground water resource. Wheat being the moderately tolerant crop face many challenges in the arid and semi-arid regions under irrigated agriculture. In view of this, the study was planned to explore the potential of durum wheat genotypes under salinity on the basis of physiological traits. Experiment was designed as RBD in three replications to evaluate 15 wheat genotypes with moderate saline irrigation (EC iw – 6 dS m −1 ) and extreme saline irrigation (EC iw – 10 dS m −1 ) along with one set of control (Best available water). Different physiological traits such as water potential (ψ p ), osmotic potential (ψ s ), relative water content (RWC), Na + and K + content were recorded in roots as well as shoots at the reproductive stage whereas photosynthetic rate and chlorophyll content were measured in the flag leaves. A significant variability (p < 0.001) was noted among the genotypes under different stress environments and it was observed that durum genotype HI 8728 and HI 8737 showed less reduction in plant water traits (RWC, ψ p and ψ s ) than the salinity tolerant checks of bread wheat KRL 99 and KRL 3–4. HD 4728 and HI 8708 maintained higher photosynthetic rate as well as higher chlorophyll content under the extreme salinity level of EC iw – 10 dSm −1 . No significant differences were found in root Na + in genotypes KRL 99 (3.17 g ), KRL 3–4 (3.34 g ) and HI 8737 (3.41 g ) while in shoots, lowest accumulation was seen in KRL 99, MACS 3949 and KRL 3–4 at EC iw – 10 dSm −1 . The mean range of K + content was 7.60–9.74% in roots and 4.21–6.61% in shoots under control environment which decreased to 50.77% in roots and 46.05% in shoots under extreme salinity condition of EC iw – 10 dSm −1 . At EC iw – 10 dSm −1 , KRL 99 maintained highest K +/ Na + in both root and shoot followed by KRL 3–4, HI 8737, MACS 3949, HD 4728 in roots and MACS 3949, KRL 3–4, MACS 4020, HD 4758, MACS 3972 and HI 8713 in shoots. The differential response of durum wheat genotypes under salinity particularly for physiological traits, confer their adaptability towards stress environments and exhibit their potential as genetic sources in breeding programs for improving salt stress tolerance.

“…Some legumes plants are more tolerant to a high salt concentration than others e.g., lentils are more tolerant than soybean and chickpea. Recently, few salt tolerant chickpea lines have been identified for survival at early seedling stage in saline soils with EC of irrigation water from 3 to 12 dS/m [15]. Earlier, pea genotypes have been categorized as sensitive, moderately tolerant or tolerant to salinity based on physiological and biochemical expressions of salt tolerance [16].…”

The decreasing agricultural lands along with waste lands and poor water resources are the main constraints for sustainable agricultural production. The need of time is to produce maximum with minimum inputs. Depleting levels of major and micro-nutrients in Indian soils have been on the rise, and situation may be more harmful if corrective measures are not followed in time. The soil nutrient deficiencies significantly reduce the crop yields in addition to the soil fertility. In preview of this, the need of the hour is to conserve agricultural sustainability, soil health enhancement, and water management. Farmers are forced to use saline water for irrigation in areas with poor quality water or less available water for irrigation, specifically in arid or semi-arid regions. Every crop plants have threshold limit of tolerance beyond which salinity decreases the crop yield. Legumes are very sensitive crops towards soil salinity, and secondary salinization mainly through irrigation water is the hardest challenge for survival of legume crops in arid regions. In view of this, the sustainability of legumes in salt affected areas is a big challenge for crop productivity being sessile to salinity. Hence, the possible strategies for sustainability of salt sensitive legumes have been briefly reviewed in this chapter.

“…The previous studies showed the effects of salinity in root growth and development in the model and common crops (Talukdar, 2011;Hasan et al 2018;Mann et al 2019). Also, there were several reports of the effect of salinity at the germination stage on forage pea (Demirkol et al 2019;Önal Aşçı and Zambi, 2020), however, no previous reports on the seedling root architecture and salinity interactions were found.…”

Background: Plants face different abiotic stresses such as salinity that affect their normal development, growth and survival. Forage pea is an important legume crop for herbage production in ruminants. Its agronomy requires high levels of irrigation and fertilization. This study aimed to evaluate the effect of salinity on seedling root system development in forage pea under semi-hydroponics conditions.Methods: Different treatment of NaCl doses (0, 50, 100, 150, 200, 250 and 300 mM) on root architecture was investigated in two different forage pea cultivars (Livioletta and Ulubatlý) with contrasting root structures under controlled conditions. The experimental design was completely randomized design with three replications and nine plants per replication.Result: Salinity affects root and shoot development differently on these cultivars. Despite the salinity, Livioletta produced more shoot (0.71 g) and root biomass (0.30 g) compared to Ulubatlý (0.52 g and 0.25 g for Root and Shoot biomass, respectively) at 150 mM and all other salinity levels. Livioletta developed a better root system and tolerated salt to a higher dose than Ulubatlý. Understanding root system responses of forage pea cultivars may allow breeding and selecting salinity tolerant cultivars with better rooting potential.
