“…Most of the plants inoculated with the strains of rhizobacteria evaluated increased root production even under water deficit conditions ( Figure 1 ). Similar responses have been reported in other crops such as maize ( Kavamura et al., 2013 ), sorghum ( Santana et al., 2020 ), cowpea ( Abiala et al., 2023 ), and spinach ( Jabborova et al., 2023 ). Many rhizospheric microorganisms are efficient in producing phytohormones such as abscisic acid, gibberellins, cytokinins, but mainly auxins, which promote root growth, branching, and hair formation ( Araújo and Hungria, 1999 ).…”

IntroductionWater scarcity is a challenge for sesame cultivation under rainfed conditions. In this scenario, a potential strategy to alleviate the water deficit is the application of plant growth-promoting bacteria. The objective of this study was to analyze the interaction of rhizobacteria with sesame cultivation under water deficit conditions.MethodsAn experiment was conducted in pots in a greenhouse using the BRS Morena sesame cultivar. The experimental design was completely randomized in a factorial scheme: 2 (irrigation regimes - daily irrigation and water deficit by suspending irrigation until 90% stomatal closure) x 6 (treatments with nitrogen or inoculants), with 5 replications. The types of fertilization were characterized by the addition of nitrogen (ammonium sulfate; 21% N), inoculants based on Bacillus spp. (pant001, ESA 13, and ESA 402), Agrobacterium sp. (ESA 441), and without nitrogen (control). On the fifth day after the suspension of irrigation, plant material was collected for gene expression analysis (DREB1 and HDZ7), activities of antioxidant enzymes (superoxide dismutase and catalase), relative proline content, and photosynthetic pigments. At the end of the crop cycle (about 85 days), production characteristics (root dry matter, aboveground dry matter, number of capsules, and thousand seed weight), as well as leaf nitrogen (N) and phosphorus (P) content, were evaluated.Results and DiscussionThere was a positive effect on both production and biochemical characteristics (proline, superoxide dismutase, catalase, and photosynthetic pigments). Regarding gene expression, most of the inoculated treatments exhibited increased expression of the DREB1 and HDZ7 genes. These biological indicators demonstrate the potential of rhizobacteria for application in sesame cultivation, providing nutritional supply and reducing the effects of water deficit.

“…This increased water availability is crucial for maintaining adequate hydration levels in plant cells. KBC indirectly reduces electrolyte leakage by promoting soil moisture retention and providing a stable environment for plant roots [ 3 ]. This, in turn, helps maintain the integrity of cell membranes, reducing the loss of electrolytes from plant cells.…”

Osmotic stress is a significant concern in agricultural crop production as it can harm crop growth, development, and productivity. Agriculture crops are particularly vulnerable to osmotic stress due to their reliance on water availability for various physiological processes. Organic amendments like activated carbon biochar and growth hormone gibberellic acid (GA3) can play a vital role. However, the time needed is to modify the established amendment to achieve better results. That’s why the current study used potassium-enriched biochar (KBC = 0.75%) with and without GA3 (15 mg/L) as amendments under no osmotic stress and osmotic stress in wheat. Results showed that GA3 + KBC caused significant enhancement in germination (9.44%), shoot length (29.30%), root length (21.85%), shoot fresh weight (13.56%), shoot dry weight (68.38), root fresh weight (32.68%) and root dry weight (28.79%) of wheat over control under osmotic stress (OS). A significant enhancement in chlorophyll a, chlorophyll b and total chlorophyll, while the decline in electrolyte leakage of wheat, also validated the effectiveness of GA3 + KBC over control in OS. In conclusion, GA3 + KBC is the most effective among all applied treatments for improving wheat growth attributes under no osmotic and osmotic stress. Further research is needed at the field level, focusing on various cereal crops, to establish GA3 + KBC as the optimal treatment for effectively mitigating the impacts of osmotic stress.

“…Only four species (23.5%) survived until the end of the growing season: Halogeton glomeratus, Suaeda acuminata, Climacoptera aralensis and Atriplex fominii [23]. The use of biochar, manure, preparations and rhizobacteria is highly effective in growing plants and improving soil properties under the influence of drought and salinity stress factors [1,[24][25][26][27]. In other similar studies, the regression rate of the Aral Sea coastline was determined at 5-year intervals from 1965 to 2019, depending on the landform, lithology, depth and salinity of the groundwater.…”

The article presents the results of research aimed at growing plants on the basis of different technologies in the relic-swamp salt-sand desert soils of the Aral Sea. The amount of annual precipitation on the soils of this area formed in the conditions of the arid climate region is 180-200 mm. Many factors should be taken into account for growing plants in these areas. It is necessary to choose a suitable halophyte plant for marshy saline soils and to take into consideration sharp changes in temperature throughout the season. Planting in these soils is due to atmospheric precipitation and groundwater. Therefore, experiments were carried out on plant cultivation in the pipe method, and the efficiency was up to 1.5 times higher than in conventional conditions. The combined use of different technologies with the pipeline method has further increased efficiency.
