By affecting 10% of the world’s total arable land, soil salinity has become a potential threat to feeding the exploding population. As per the current scenario, among 1,125 million hectares of salt-affected land, nearly 76 million hectares are seriously affected due to human-induced salinization. Due to soil salinization, crop productivity is being hampered. In order to enhance productivity, there is an urgent need to shift from traditional methods to advanced 3E (efficient, economic, and environmentally sound) technology for soil salinity reclamation and management to achieve better soil health and sustainable crop production. The detailed mechanism of salt interference with various pathways involved in plant growth and development needs to be understood. This article critically reviews the mechanism of harmful salt interference with nutrient dynamics in soil and various physiological pathways involved in crop growth to apply various soil-oriented (crop residue management, biochar application, and agroforestry system) and plant-oriented [plant growth-promoting microbes (PGPMs), plant growth regulators, and nanotechnology] promising reclamation and rehabilitation approaches to mitigate its hazardous effect on soil salinity. The monitoring and assessment of salt-affected soils through remote sensing (RS) and geographical information systems (GISs) are pivotal in the management and framing of long-term policies to confront alarming threats to crop productivity and sustainability. This study provides an insight into recent developments in soil salinity management and proposes futuristic solutions that could ameliorate soil salinity to attain crop sustainability under adverse environmental conditions.

Underutilized legumes are nutritionally important group of crops with immense medicinal values and contribute significantly as a resource of profit to the poor farmers. Horse gram (Macrotyloma uniflorum) and Bambara groundnut (Vigna subterranean) are two such underutilized legumes largely grown in India and other South Asian countries contribute significantly to the diet of poor people during adverse climatic condition particularly to them who cannot afford to grow pulses that require balanced nutrition. They are fit for diversification, green manuring and may be used as cover crops and also thrive well under stressful dry environment. Changing lifestyle and climate variability bring enough scope for their cultivation and profitability. Horse gram is medicinally superior to other traditionally consumed pulses and can fight against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. Besides its use as fodder crop, it cures urinary stones, gastritis, excessive post-partum bleeding, rheumatism, coronary heart disease, diabetes, etc. Bambara groundnut has distinctive drought adaptations and is suitable under semi-arid climate. Extract of Bambara groundnut is used as weaning food in African countries. The present review focuses on origin, morphology, genetic diversity, traditional uses, nutritional and medicinal importance, potential as food and fodder crop and constraints to higher productivity of both horse gram and Bambara groundnut.
