“…The situation is worse in sodic-saline soil where plants suffer from the limited availability of nutrients, water uptake shortage caused by high osmotic pressure, and ion toxicity due to elevated Na + and Cl − ions [ 5 , 6 ]. Another threat to plant performance in sodic-saline soil is soil dispersion and the swelling of clay platelets and aggregates caused by high Na + content [ 7 ].…”

The utilization of low-quality water or slightly saline water in sodic-saline soil is a major global conundrum that severely impacts agricultural productivity and sustainability, particularly in arid and semiarid regions with limited freshwater resources. Herein, we proposed an integrated amendment strategy for sodic-saline soil using biochar and/or plant growth-promoting rhizobacteria (PGPR; Azotobacter chroococcum SARS 10 and Pseudomonas koreensis MG209738) to alleviate the adverse impacts of saline water on the growth, physiology, and productivity of maize (Zea mays L.), as well as the soil properties and nutrient uptake during two successive seasons (2018 and 2019). Our field experiments revealed that the combined application of PGPR and biochar (PGPR + biochar) significantly improved the soil ecosystem and physicochemical properties and K+, Ca2+, and Mg2+ contents but reduced the soil exchangeable sodium percentage and Na+ content. Likewise, it significantly increased the activity of soil urease (158.14 ± 2.37 and 165.51 ± 3.05 mg NH4+ g−1 dry soil d−1) and dehydrogenase (117.89 ± 1.86 and 121.44 ± 1.00 mg TPF g−1 dry soil d−1) in 2018 and 2019, respectively, upon irrigation with saline water compared with non-treated control. PGPR + biochar supplementation mitigated the hazardous impacts of saline water on maize plants grown in sodic-saline soil better than biochar or PGPR individually (PGPR + biochar > biochar > PGPR). The highest values of leaf area index, total chlorophyll, carotenoids, total soluble sugar (TSS), relative water content, K+ and K+/Na+ of maize plants corresponded to PGPR + biochar treatment. These findings could be guidelines for cultivating not only maize but other cereal crops particularly in salt-affected soil and sodic-saline soil.

“…Scientists reported that the uptake of different nutrients by garlic plant varied significantly due to the different application levels of K. Potassium alone induced maximum uptake of all the elements studied (N, P, K, S, Ca, Mg, B, and Na) at K at 200 kg•ha −1 and the lowest in control K0 treatment [29]. It was found that these essential and beneficial nutrients could protect crop plants against both abiotic and biotic stresses by enhancing the plant resistance power and regulating the mineral nutritional status [32].…”

Soil salinity is one of the major yield-limiting factors for crop production in many agricultural regions all over the world. Besides following efficient management practices at the field scale to reduce accumulation of salts in the effective root-zone, the effective use of treatments to alleviate the effects of salinity stress and improve crop salt tolerance is a promising solution to ensure crop production in such adverse conditions. A field experiment was carried out to investigate the effect of foliar spray with plant-based biostimulant (i.e. with and/or without 3% yeast extract), three levels of proline (0, 25, and 50 mM), and combined with potassium fertilizers, as potassium sulfate, 48% K 2 O (0, 50, and 100 kg/fed.) on growth promotion, chemical composition of garlic leaves, bulb quality parameters as well as yield and its components of garlic plant grown under moderate saline soil. Results revealed that the interaction between foliar spray with yeast extract at 3% and proline at 50 mM combined with proper K level at 100 kg/fed., was the best interaction treatment for increasing vegetative growth parameters, i.e. plant height, number of leaves per plant, and mineral contents (N, P, K, S, Ca and Mg in leaves), and proline content of garlic leaves after 135 days from planting time, total yield/fed., and garlic yield quality parameters at harvesting time. In conclusion, the detrimental effects of salinity stress can be alleviated by stress tolerance-inducing compounds, such as yeast extract and proline with proper application rate of K fertilization during the growing season of garlic crop.

“…This volume incudes the sustainable plant production, as a complex challenge of modern agriculture, under abiotic stresses such as drought, salinity, heavy metals and waterlogging in the existence of some nutrients like silicon, selenium, zinc, copper and nitrogen.More volumes will be edited by some distinguished scientists such as QaisarMahmood (COMSATS University Abbottabad, Pakistan), Sheikh AdilEdrisi (Banaras Hindu University, India), VishalTripathi (Banaras Hindu University, India), André Rodrigues dos Reis (São Paulo State University, Brazil), and HarikeshBahadur Singh (Banaras Hindu University, India). Plants could alleviate the abiotic stresses through many approaches including plant growth-promoting rhizobacteria (Ramakrishna et al, 2019 andGoswami andDeka, 2020), application of nanomaterials (Singh and Husen, 2019) or nanoparticles of some metals/metalloids such as nano-manganese (Ye et al, 2019), nano-zinc oxide (Dimkpa et al, 2019), nano selenium (El-Ramady et al, 2018a) and nano silica (Alsaeedi et al, 2017(Alsaeedi et al, & 2019; application of nitric oxide (Wei et al 2019), using of kaolin (Brito et al, 2019), and application of nutrients (El-Ramady et al, 2018b). It could be investigated the growth of plants under abiotic stress using different applications of metabolomics (Feng et al, 2019).…”

P LANT nutrition is considered one of the most important plant sciences dealing with plant productivity and hencehas a great role in global food security. The proper nutrition of cultivated plants in its time, source, amount, and place is the guarantee for this satisfied production. Therefore, the science of plant nutrition is an increasingly important area in plant sciences, which has a direct and indirect link with human health. The concept of plant nutrition has been changed from theinvestigation of the application, translocation and metabolism of nutrients by plants into the "engineering" of these applied nutrients for human health. So, it has been established that "feed the soil to feed the human". Thus, recent developments in the field of plant nutrition have led to a renewed interest in the relationship between plant nutrition and human health. Therefore, this is an introduction to highlight on the new book series "Sustainable Plant Nutrition under a Changing World", which will be published by Springer Nature. This book series will focus on advanced issues in plant nutrition under stressful environments starting with the changing in global climate and reaching to the production of cultivated crops biofortified with desirable nutrients like iodine, and selenium.
