“…Irrigation with salt water in the vegetative growth stage has a lesser negative impact on seed production than in the fruiting stage. 48 Using water with different electrical conductivities and adding nitrogen, phosphorus and potassium salts can alleviate salt stress in plants by promoting ion homeostasis. 49,50 It has been reported that a mixture of organic matter, sulfur, and gypsum can reduce soil salinity and maintain soluble and exchangeable cations, promoting plant growth.…”

Sustaining agricultural productivity is essential to ensuring food security. Climate change, increasing population and dwindling resources are factors of concern threatening crop productivity. Research across the globe have focused on seeking innovative measures to protect and enhance crop yield. We explored and analyzed peer-reviewed literature to provide an understanding of current and emerging trends in the field. A bibliometric method was followed using the database Scopus. Search queries used to retrieve documents were “Agriculture/crop productivity” and “Plant stress”. The study period was restricted to the last five years, from 2017-2021. The search query found 2207 documents in Scopus under the agriculture and plant stress theme. Increasing growth of publications was observed in successive years. Research activities in this field have the most contributors from Asian countries – China and India followed by the US. The major stresses affecting agricultural productivity being investigated were-Water stress, Temperature stress, Salinity stress. Amongst these, the theme related to water stress/ precipitation/ drought stress was the most investigated. The availability of water has a pivotal role in sustainable agriculture. The use of conservation agricultural practices such as intercropping, no-tillage, and soil mulching has proven to be effective in retaining soil water content and reducing the dependency on irrigation, especially in rainfed areas, thereby assisting in drought mitigation and increasing crop yield. Precision agriculture approach employing satellite data to predict weather and rainfall and early detection of stress signals using hyperspectral reflectance has shown promising results in ensuring sustained productivity. Breeding and transgenic approaches for plants with higher water use efficiency (WUE) and the ability to tolerate water stress are key areas of research being followed throughout the world.

“…Although several studies address the effects of salt stress on passion fruit (Lima et al, 2021;Sá et al, 2021;Silva et al, 2021), the tolerance of this crop to salinity varies according to crop development stage (Soares et al, 2021). In this context, the objective of this study was to determine the quantum yield, chlorophyll levels, and cell damage in yellow passion fruit cultivated under different irrigation strategies with brackish water and potassium fertilization in the second year of its cultivation.…”

The occurrence of water sources with high concentrations of salts in the semiarid region of Northeast Brazil stands out as a limiting factor in the cultivation of irrigated yellow passion fruit. Thus the search for irrigation strategies with brackish water is fundamental for the sustainability of irrigated crops. The objective of the present study was to determine the quantum yield, chlorophyll levels, and cell damage in yellow passion fruit cultivated under different irrigation strategies with brackish water and potassium fertilization. The experiment was conducted under field conditions in São Domingos -PB, Brazil, adopting a randomized block design in a 6×2 factorial scheme, consisting of six strategies of use of brackish water applied in the different phenological stages of crop and two doses of potassium (60 and 100% of the recommendation), with four replicates. Two levels of irrigation water salinity were used, with low (1.3 dS m -1 ) and high electrical conductivity (4.0 dS m -1 ). The potassium dose of 100% recommendation corresponds to the application of 345 g of K 2 O per plant per year. The use of brackish water (4.0 dS m -1 ) increased chlorophyll fluorescence and negatively affected the photosynthetic pigments of yellow passion fruit, regardless of the phenological stage. Salt stress intensified intercellular electrolyte leakage in passion fruit plants under higher dose of potassium. Our results show that fertilization equivalent to 100% of the potassium recommendation is excessive for yellow passion fruit 'BRS GA1' in the tropical semiarid region under salt stress conditions.

“…Climatic changes cause abiotic stresses in plants and trigger physiological changes which reduce the production and quality of agricultural products. This scenario shows a growing demand for food, fibers, and bioenergy and draws attention to cultivated species with multiple applications, such as naturally colored fiber (NCF) cotton (Gossypium hirsutum L.) (Soares et al, 2021).…”

Abiotic stresses reduce the yield and quality of cotton production, however, this problem may be mitigated by exogenous elicitors. This study investigated physiological adjustments, improvement in productivity, and fiber yield and quality from naturally colored cotton BRS Topázio cultivar under leaf silicon spraying. Five doses of silicon (0, 50, 100, 150, and 200 mg L-1) were tested in a completely randomized design. The variables assessed were physiological, production, fiber yield and quality. Data were submitted to principal component analysis, multivariate and univariate variance, and multiple linear regression. Silicon promotes physiological adjustments, increased production, cotton fiber yield and quality. Optimum silicon dose varies depending on the variable response. Fiber quality from plants treated with silicon is within the expected pattern for this cultivar and the international standard D-4605 of the American Society for Testing and Materials. Therefore, planting BRS Topázio cultivar under silicon foliar applications may be recommended to improve the naturally colored fiber cotton production chain in the Brazilian semiarid region.
