“…But the success of seed priming depends on plant genotype/specie, environmental conditions, seed vigor and priming technique being employed to improve seed germination (Adhikari et al, 2022). Solid Matrix Priming Among the several priming methods, Solid matrix priming is an important priming method for repairing aging and improving seed quality (Muhie et al, 2020a). SMP technique proposed by Eastin (1990) involves combination of seed, solid matrix and water to control temperature, oxygen and moisture that affect germination.…”

Poor crop stand is one of the most common abiotic constrain faced by vegetable growers of developing countries due to production of low quality seed. Multiple factors, especially abiotic stresses and seed dormancy restrict seed germination and seedling growth. Up till now, seed priming is still considered as effective and cheapest method to enhance seed germination and to mitigate the drastic effect of abiotic stresses. Manipulation of seed hydration through solid matrix priming technique not only improves germination characteristics but also stimulates biochemical processes like restoration of metabolic activities through protein and nucleic acid synthesis (RNA and DNA), increases enzymatic activities, and improves the storage of organic substances in germinating seeds. It was also found effective in improving seedling establishment under salinity, drought, and temperature stresses by activating defence mechanisms. Therefore, this review highlights the role of solid matrix priming in improving the germination and stand establishment of vegetable crops under suboptimal conditions.

“…Among the various organic amendments practices, VC and VW are low-cost techniques to reduce the detrimental impact of salts on plants ( Table 1 , [ 53 ]). The VC has been shown to reduce salt toxicity and enhance the emergence rate and seedling growth of different plants [ 54 , 55 ]. The VC enhances soil organic matter in salt soils by decreasing electrical conductivity (EC), bulk density and increasing field capacity, saturated hydraulic conductivity, and cation exchange capacity [ 56 ].…”

“…The soil amendment of VC increased exchangeable K + , Ca 2+ , and Mg 2+ , plant height, total dry matter content, and decreased exchangeable Na + in the saline soil [ 63 , 64 , 65 ]. In addition, VC application reduced salt-induced injuries of plants grown in saline soil by increasing relative water content, stomatal conductance, chlorophyll-a, superoxide dismutase (SOD), ascorbate peroxidase (APX), and catalase (CAT) activities and decreased electrolyte leakage and malondialdehyde (MDA) levels [ 55 , 66 , 67 , 68 ].…”

Natural and/or human-caused salinization of soils has become a growing problem in the world, and salinization endangers agro-ecosystems by causing salt stress in most cultivated plants, which has a direct effect on food quality and quantity. Several techniques, as well as numerous strategies, have been developed in recent years to help plants cope with the negative consequences of salt stress and mitigate the impacts of salt stress on agricultural plants. Some of them are not environmentally friendly. In this regard, it is crucial to develop long-term solutions that boost saline soil productivity while also protecting the ecosystem. Organic amendments, such as vermicompost (VC), vermiwash (VW), biochar (BC), bio-fertilizer (BF), and plant growth promoting rhizobacteria (PGPR) are gaining attention in research. The organic amendment reduces salt stress and improves crops growth, development and yield. The literature shows that organic amendment enhances salinity tolerance and improves the growth and yield of plants by modifying ionic homeostasis, photosynthetic apparatus, antioxidant machineries, and reducing oxidative damages. However, the positive regulatory role of organic amendments in plants and their stress mitigation mechanisms is not reviewed adequately. Therefore, the present review discusses the recent reports of organic amendments in plants under salt stress and how stress is mitigated by organic amendments. The current assessment also analyzes the limitations of applying organic amendments and their future potential.

“…Various crop seed priming agents have been explored for abiotic and biotic stress tolerance. In onions, vermicompost seed priming enhanced germination, and healthy plants withstood drought, salinity, and temperature stresses (Muhie et al, 2020 ). This was due to the improved activities of enzymes such as catalase, superoxide dismutase, and ascorbate peroxidase.…”

Concurrent waterlogging and anthracnose-twister disease in rainy-season onions (Allium cepa): Impact and management

Waterlogging and anthracnose-twister disease are significant obstacles in rainy-season onion cultivation. As a shallow-rooted crop, onions are highly sensitive to waterlogging. Wherever rainy-season onion cultivation has been undertaken, the anthracnose-twister disease complex is also widespread across the world in addition to waterlogging. Waterlogging is the major predisposing factor for anthracnose and other fungal diseases. However, studies on the combined stress impact on onions have been ignored. In the present review, we have presented an overview of the anthracnose-twister disease, the waterlogging effect on host physiology, host-pathogen interaction under waterlogging stress, and appropriate management strategies to mitigate the combined stress effects. Crucial soil and crop management strategies can help cope with the negative impact of concurrent stresses. Raised bed planting with drip irrigation, the use of plant bio-regulators along with nutrient management, and need-based fungicide sprays would be the most reliable and feasible management options. The most comprehensive solution to withstand combined stress impacts would be a genetic improvement of commercial onion cultivars.
