“…This might be due to the fact that most glycophytic crops originated and were domesticated in non-saline habitats (Cheeseman 2015), with the exception of e.g. sugar beet which has halophytic ancestors (Rozema et al 2015).…”

Thirty crop species provide 90% of our food, most of which display severe yield losses under moderate salinity. Securing and augmenting agricultural yield in times of global warming and population increase is urgent and should, aside from ameliorating saline soils, include attempts to increase crop plant salt tolerance. This short review provides an overview of the processes that limit growth and yield in saline conditions. Yield is reduced if soil salinity surpasses crop-specific thresholds, with cotton, barley and sugar beet being highly tolerant, while sweet potato, wheat and maize display high sensitivity. Apart from Na , also Cl , Mg , SO or HCO contribute to salt toxicity. The inhibition of biochemical or physiological processes cause imbalance in metabolism and cell signalling and enhance the production of reactive oxygen species interfering with cell redox and energy state. Plant development and root patterning is disturbed, and this response depends on redox and reactive oxygen species signalling, calcium and plant hormones. The interlink of the physiological understanding of tolerance processes from molecular processes as well as the agronomical techniques for stabilizing growth and yield and their interlinks might help improving our crops for future demand and will provide improvement for cultivating crops in saline environment.

“…Sugar beet is a deep rooting crop and shows relatively higher tolerance to water stress caused by either soil moisture depletion or soil salinity [38,40]. Over time, table beet, fodder beet, red beet, and sugar beet have been evolved from sea beet which can be cultivated in a wide range of climatic conditions including saline prone regions [41,42]. Estimations show that the yield components of sugar beet are enhanced by irrigation with various concentrations of saline water [43,44].…”

Attempts to cultivate sugar beet (Beta vulgaris spp. vulgaris) in the sub-tropical saline soils are ongoing because of its excellent tolerance to salinity. However, the intrinsic adaptive physiology has not been discovered yet in the sub-tropical climatic conditions. In this study, we investigated morpho-physiological attributes, biochemical responses, and yield of sugar beet under a gradient of salinity in the soil-pot culture system to evaluate its adaptive mechanisms. Results exhibited that low and high salinity displayed a differential impact on growth, photosynthesis, and yield. Low to moderate salt stress (75 and 100 mM NaCl) showed no inhibition on growth and photosynthetic attributes. Accordingly, low salinity displayed simulative effect on chlorophyll and antioxidant enzymes activity which contributed to maintaining a balanced H 2 O 2 accumulation and lipid peroxidation. Furthermore, relative water and proline content showed no alteration in low salinity. These factors contributed to improving the yield (tuber weight). On the contrary, 250 mM salinity showed a mostly inhibitory role on growth, photosynthesis, and yield. Collectively, our findings provide insights into the mild-moderate salt adaptation strategy in the soil culture test attributed to increased water content, elevation of photosynthetic pigment, better photosynthesis, and better management of oxidative stress. Therefore, cultivation of sugar beet in moderately saline-affected soils will ensure efficient utilization of lands.

“…It is important to manage irrigation water and farm soil, and even more so the use of brackish water and salted soils in a strategy called biosaline agriculture. The crop cultivation of halophytes has been gaining interest due to the difficulties related with obtaining salt‐tolerant crops through conventional or genetic modification, the productivity uncertainties in field conditions and the concerns with environmental impacts and consumer acceptance (Ismail & Horie, ; Lucht, ; Nuccio, Paul, Bate, Cohn, & Cutler, ; Rozema et al, ; Woodbury, DiTommaso, Thies, Ryan, & Losey, ).…”

Funding information CESAMSaline agriculture and the crop cultivation of halophytes represent an alternative for the reclamation of salinized soils and for the management of irrigation water. Halotolerant plant growth promoting bacteria with biocontrol effect, as an alternative to commercial fungicides, may contribute to improve crop productivity while mitigating saline stress effects. The objective of this work was to isolate autochthonous rhizobacteria with biocontrol features, to be used as germination enhancers and plant-growth promoting agents in the crop cultivation of Salicornia ramosissima. A set of isolates obtained from the rhizosphere of S. ramosissima was characterised in terms of Gram, motility, salt tolerance and biocontrol traits (hydrogen cyanide production, antifungal activity and production of extracellular lipases and proteases). One Gram-positive motile isolate that tested positive for all biocontrol traits was identified by 16S rRNA gene sequencing as Bacillus aryabhattai. The inoculation of S. ramosissima seeds with B. aryabhattai SP1016-20 reduced the negative effect of salinity on the germination efficiency. At the highest tested salinity (30 g/L NaCl) the final germination efficiency of inoculated seeds doubled in relation to noninoculated controls. Although the mechanisms involved in the biocontrol effect were not defined in the current work, the results highlight the potential of Bacillus aryabhattai SP1016-20 as a plant-growth promoting agent for the crop cultivation of Salicornia and contribute to the strengthening of the scientific basis of biosaline agriculture and plant growth promoting rhizobacteria-assisted crop cultivation of halophytes in saline soils and estuarine sediments.
