This study aimed to evaluate the effect of two irrigation systems (deficit (DI)—70% field capacity—and full (FI)—100% capacity) and a biostimulant formulation (silicon (Si) calcium (Ca) at four different rates) on chemical composition fruit quality greenhouse-grown tomatoes. Deficit application influenced proximate tomato fruits. Fructose glucose were main soluble sugars, while malic citric acids predominant organic acids. Free sugar acid content increased under DI applications. In contrast, deficit combined with decreased α-tocopherol levels. terms carotenoids, lycopene β-carotene concentrations higher irrigation. The fatty palmitic (C16:0) linoleic (C18:2n6) acids, saturated (SFA) polyunsaturated (PUFA) being classes. Moreover, applications reduced total phenolic regardless regime, whereas flavonoid when biostimulants applied FI conditions. Regarding antioxidant activity (assessed by TBARS OxHLIA assays), variable response was observed. conclusion, Si Ca showed promising results in yield it could be considered sustainable strategy mitigate adverse effects climate change horticultural crops.

Organic fertilizers are safer and more eco-friendly than chemical fertilizers; hence, organic can be used to support sustainable farming. The effects of PGPRs manifold in agriculture, especially monoculture crops, where the soil needs modified increase germination, yield, disease resistance. objective this study was assess combined with fertilizer on yield productivity canola. Canola chosen for its global importance as an oilseed crop responsiveness amendments, making it ideal evaluating synergistic health. This research, which carried out over two years, aimed at establishing effectiveness together inorganic canola yields performed a two-factorial RCBD design under field conditions. We applied Azotobacter salinestris Bacillus subtilis biochar, compost, animal manure, poultry NPK fertilizer. Insect pest management other agronomic practices were maintain experiment. traits enhanced by combination fully recommended N: P:K ratio (140:55:40 kg/ha). Additionally, application biochar 2 tons/ha improved quality canola, well structure nutrient regulation soil. In light these results, we recommend seeds along either t/ha or entire dose These strategies help producers environment Combining enhances efficiency, promotes growth, boosts stress resilience, addressing agricultural environmental challenges.

Silicon (Si) is a beneficial nutrient well-known for its functions in enhancing plant resistance to abiotic and biotic stresses. How Si application affects tomato yield quality underlying physiological mechanisms remain largely unclear. Our pot experiment showed that (45 kg ha⁻¹ Na₂SiO₃) significantly promoted accumulation of nitrogen, phosphorus, potassium, the shoot soil-cultured greenhouse. Such improved mineral nutrition favored Si-applied performance terms height, stem diameter, single fruit weight, yield, as indicated by significant increases 11.34%, 53.57%, 62.12%, 33.81%, respectively, when compared control (0 Na₂SiO₃). Higher catalase superoxide dismutase activities contrast lower concentrations hydrogen peroxide malondialdehyde suggested facilitated health. Importantly, upregulated expression phytoene synthase carotenoid isomerase enhanced corresponding enzyme activities, resulting higher lycopene fruit. also stimulated vitamin C synthesis genes (GDP-D-mannose-3', 5'-isomerase, GDP-L-galactose phosphorylase, dehydroascorb-ate reductase, monodehydroascorbate reductase) levels accumulation. health, nutritional at molecular level, favoring production towards sustainable agricultural development.

Abstract Background and Aims: Potassium (K)- bearing minerals are vital for soil fertility act as slow-release reservoirs crop productivity. Organic acids, such oxalic citric enhance K dissolution. Methods Time-dependent experiments measured dissolution from in acids. Mehlich-1 extraction atomic absorption spectrophotometry quantified release over intervals under controlled conditions. Results Oxalic acid enhanced by 25% more than acid. For biotite-mica, increasing concentration 0.5 to 5.0 mmol L⁻¹ raised 800 1600 mg kg⁻¹. During a further increase 10 L⁻¹, slightly improved was recorded. Percentage varied mineral, muscovite-mica, K-feldspar recorded 5–11%, 3–7%, 2–6% respectively. Citric caused significant between 1.0 with increases up L⁻¹. Above 5 muscovite-mica dissolved biotite-mica K-feldspar, showing higher percentages of 3.1–7.5% that 2.4–6.2%. Conclusion acids via chelation, destabilization mineral surfaces, solubility increases. acid’s superior performance highlights its role improving fertility. Also, outperformed dissolving minerals, underscoring the importance targeted nutrient management strategies.

Soil bacteria play a crucial role in enhancing mineral weathering, thereby facilitating the release of structural ions into environment. Pseudomonas brassicacearum NFM421, root-isolated bacterium, produces two different siderophores form pyoverdine and ornicorrugatin. We studied interaction between this bacterium biotite─a natural iron-bearing phyllosilicate─to assess factors governing siderophore-mediated biogenic weathering. demonstrated that bacterial Fe is an essential factor driving biotite Our findings suggested lipopeptidic siderophore ornicorrugatin might be more effective than as weathering agent. This secondary siderophore's production maintained even when iron requirement fulfilled. Moreover, we observed another mechanism requiring direct physical contact enable P. to acquire from soil minerals.
