Abstract Background Soils affected by salinity are a recurring problem that is continually increasing due to the impact of climate change on weather conditions and ineffective agricultural management practices. The use plant growth promoting (PGP) Bacteria can alleviate its effects. In this regard, genus Rhizobium has demonstrated excellent PGP capabilities through various promotion mechanisms may therefore be promising biofortifier under saline conditions. However, little known about production volatile organic compounds (VOCs) bacteria their effects development.

Lettuce is a vegetable that contributes vitamins, minerals, fibre, phenolic compounds and antioxidants to the human diet. In search for improving production conditions crop health, use of microorganisms with plant growth-promoting capabilities, such as soil yeasts (PGPY), in conjunction nanotechnology could offer sustainable development agroecosystems. This study evaluated synthesis health-promoting bioactive lettuce under application yeast an iron nanoparticle (NP-Fe2O3) encapsulated alginate beads. Two strains, Candida guillermondii Rhodotorula mucilaginosa, consortium both were used presence absence Fe2O3-NPs. Phenolic identified quantified via HPLC-ESI-Q-ToF antioxidant activity.

Potato has great nutritional and economic importance in agriculture. However, Rhizoctonia solani represents a significant risk, reducing the yield quality of potato production. Flesh-colored (FCP) extracts show vitro inhibitory effects against R. solani, although environmental factors may reduce their stability. Solid lipid nanoparticles (SNLs) offer solution by encapsulating these compounds, preventing degradation, improving delivery, positioning solid as promising technology for sustainable extract application. A greenhouse assay at two phenological stages under inoculation was used to evaluate photosynthetic response (photosynthetic parameters pigments) doses nanoencapsulated (SNL + FCP). During commercial fungicide application, stomatal conductance, rate, internal CO2 concentration increased compared with those non-inoculated control (NT), whereas maintained levels similar NT, suggesting possible regulation defense system. In terms pigments, SLN FCP chlorophyll concentrations, unlike inoculated plants, which significantly decreased. Component analysis revealed that lower dose primarily B synthesis, higher control. These findings suggest an improved from fungicides, particularly respect pigments. further research is needed, results indicate potential eco-friendly phytopathogenic fungi

Deficit irrigation water (DW) is one of the main stress factors that negatively affect cotton cultivation. Hence, identification cultivars tolerant to DW and sandy soil conditions particularly needed. Understanding response essential for estimating needs. Besides, by understanding physiological antioxidant status, reflecting distinct growth, yield, fiber quality traits under DW, cultivar can be identified in early stage plant growth. Therefore, two (Giza 86 Giza 92, selected their suitability climatic study area) were evaluated this regimes (80% or 60% crop evapotranspiration; ETc) vs. complete (CW; 100% ETc as a control).

Environmental stresses biotic abiotic nature affect development metabolism can, consequently, impact biomass yield phytochemical content. Stress factors can be divided into eustressors distressors; while former stimulate positive response terms growth, productivity, resistance, latter impair development. Eustressors that, applied at low–moderate doses, improve performance. Several studies have investigated different types distress C. evaluated on less attention has been paid study eustress. This review discusses concept eustress by referring recent literature extrapolates it applications cultivation.
