“…Salinity leads to cause osmotic stress and ionic toxicity which adversely affects growth and economic yield of plants [ 6 ]. In Pakistan, salinity stress is at an alarming rate because total cultivated area is 22.1 Mha out of which 6.28 Mha area is salt affected [ 7 ]. Human activities are also responsible for secondary salinization by mishandling the land and primary source of salinity [ 8 ].…”

Salinity in soil and water is one of the environmental factors that severely hinder the crop growth and production particularly in arid and semi-arid regions. A pot experiment was conducted to investigate the impact of salinity levels (1.5 dS m-1, 3.5 dS m-1, 7.5 dS m-1 and 11.5 dS m-1) on emergence, growth and biochemical traits of moringa landraces under completely randomized design having three replications. Four landraces of Moringa oleifera (Faisalabad black seeded moringa [MFB], Patoki black seeded moringa [MPB], Faisalabad white seeded moringa [MFW] and Rahim Yar Khan black seeded moringa [MRB]) were selected for experimentation. All the salinity levels significantly affected the emergence parameters (time to emergence start, time to 50% emergence, mean emergence time, emergence index and final emergence percentage) of moringa landraces. However, 1.5 dS m-1 and 3.5 dS m-1 were found more favorable. Higher salinity levels (7.5 dS m-1 and 11.5 dS m-1) significantly minimized the root surface area, root projected area, root volume and root density as compared to 1.5 dS m-1, 3.5 dS m-1. Number of branches, leaves, leaflets and leaf length were also adversely affected by 7.5 dS m-1 and 11.5 dS m-1. Maximum seedling fresh and dry weights, and seedling length were recorded at 1.5 dS m-1 followed by 3.5 dS m-1. Chlorophyll a and b contents, carotenoids and membrane stability index were also observed highest at salinity level of 1.5 dS m-1. In case of moringa landraces, MRB performed better regarding emergence attributes, growth parameters, and biochemical analysis followed by MFW as compared to MFB and MPB. Moringa landraces i.e. MRB and MFW were found more tolerant to salinity stress as compared to MFB and MPB.

“…Also some areas of the world receive inadequate rainfall causing hindrance in efficient leaching of salts from root zone ( Francois et al., 1994 ). However, in Pakistan, one of the main factor causing salinity is the imprudent use brackish underground water as irrigation water ( Malik et al., 2021 ). Worldwide, irrigated agriculture is a major reason for salinity, which frequently leads to secondary salinization of land and water resources in arid and semi-arid conditions.…”

An overview of salinity stress, mechanism of salinity tolerance and strategies for its management in cotton

et al. 2022

Salinity stress is one of the primary threats to agricultural crops resulting in impaired crop growth and development. Although cotton is considered as reasonably salt tolerant, it is sensitive to salt stress at some critical stages like germination, flowering, boll formation, resulting in reduced biomass and fiber production. The mechanism of partial ion exclusion (exclusion of Na+ and/or Cl–) in cotton appears to be responsible for the pattern of uptake and accumulation of harmful ions (Na+ and Cl) in tissues of plants exposed to saline conditions. Maintaining high tissue K+/Na+ and Ca2+/Na+ ratios has been proposed as a key selection factor for salt tolerance in cotton. The key adaptation mechanism in cotton under salt stress is excessive sodium exclusion or compartmentation. Among the cultivated species of cotton, Egyptian cotton (Gossypium barbadense L.) exhibit better salt tolerance with good fiber quality traits as compared to most cultivated cotton and it can be used to improve five quality traits and transfer salt tolerance into Upland or American cotton (Gossypium hirsutum L.) by interspecific introgression. Cotton genetic studies on salt tolerance revealed that the majority of growth, yield, and fiber traits are genetically determined, and controlled by quantitative trait loci (QTLs). Molecular markers linked to genes or QTLs affecting key traits have been identified, and they could be utilized as an indirect selection criterion to enhance breeding efficiency through marker-assisted selection (MAS). Transfer of genes for compatible solute, which are an important aspect of ion compartmentation, into salt-sensitive species is, theoretically, a simple strategy to improve tolerance. The expression of particular stress-related genes is involved in plant adaptation to environmental stressors. As a result, enhancing tolerance to salt stress can be achieved by marker assisted selection added with modern gene editing tools can boost the breeding strategies that defend and uphold the structure and function of cellular components. The intent of this review was to recapitulate the advancements in salt screening methods, tolerant germplasm sources and their inheritance, biochemical, morpho-physiological, and molecular characteristics, transgenic approaches, and QTLs for salt tolerance in cotton.

“…Salinization is one of the leading causes of soil degradation in Sindh and Punjab, reducing its fertility and overall productivity. According to a study by Malik et al (2021), the salinity levels in the soils of Punjab province have increased significantly in the past few decades due to over-irrigation, poor drainage, and inadequate soil management practices. The authors used remote sensing data to map land use changes and soil salinity levels in the study area, finding that the total area affected by soil salinity increased by 43% during the study period.…”

The Northern Indian Plains are facing severe environmental challenges that threaten the health and well-being of millions of people in the region. Deforestation, soil degradation, water pollution and scarcity, and poor air quality are some of the major environmental issues that require urgent attention. Deforestation in the region has resulted in the loss of biodiversity, soil erosion, and reduced water availability. Soil degradation is another major issue in the region, resulting from unsustainable agricultural practices, overuse of chemical fertilizers, and erosion caused by deforestation. It has also reduced soil fertility, resulting in lower crop yields and reduced agricultural productivity. Using chemical fertilizers and pesticides has also led to water pollution, affecting the health of people and animals who rely on these water sources. Water scarcity and pollution are major challenges in the region, with many people having limited access to clean and safe drinking water. The pollution of water sources due to industrial and agricultural activities has further compounded the problem, leading to waterborne diseases and various health issues. Finally, air pollution is a major environmental challenge in the Northern Indian Plains, with high levels of particulate matter and other pollutants affecting people's health in the region. Burning crops, vehicular emissions, and industrial activities contribute to poor air quality, leading to respiratory illnesses, cardiovascular disease, and other health issues. This study aims to provide a comprehensive overview of the mentioned environmental challenges in the Northern India Plains by utilizing contemporary literature and evidence-based research to establish its findings.
