Drought-induced osmotic stress is a significant constraint to soybean growth and yield, necessitating the development of effective mitigation strategies. Silicon acts as an important strategy mitigate negative effects drought stress. The study was aimed evaluate potential soil-applied silicon in alleviating soybean. Two field capacities were tested: control (85% FC) (50% FC), with four application rates (0, 100, 200, 300 kg ha−1) applied at sowing. Drought significantly affected morphological parameters plant height, leaf area, water reduced by 25%, 20%, 36%, respectively, while root length increased compared control-85% FC. However, density, surface biomass Additionally, photosynthetic rates, chlorophyll b levels, stomatal conductance, increasing malondialdehyde hydrogen peroxide. natural defense system upregulated, activity phenolics, soluble proteins, antioxidant enzymes like catalase, superoxide dismutase, peroxidase. applications, especially 200 ha−1, alleviated improving morphophysiological biochemical traits soybeans. Compared control, Si200 length, rate, 22%, 39%, 23%, 17%, control. Furthermore, peroxide levels 21% 10%, enhancing resilience. supplementation also boosted attributes, total enzyme activities 30%, 55%, 19%, 24%, 31%, under conditions. In crux, ha−1 effectively mitigated soybean, becoming more sustainable approach sustain crop yield food security.

Enhancing Tomato Growth and Quality Under Deficit Irrigation with Silicon Application

Agronomy, Journal Year: 2025, Volume and Issue: 15(3), P. 682 - 682

Published: March 12, 2025

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.

Effects of Oak Leaf Extract, Biofertilizer, and Soil Containing Oak Leaf Powder on Tomato Growth and Biochemical Characteristics under Water Stress Conditions

Agriculture, Journal Year: 2022, Volume and Issue: 12(12), P. 2082 - 2082

Published: Dec. 4, 2022

Drought stress is one of the most significant abiotic stresses on sustainability global agriculture. The finding natural resources essential for decreasing need artificial fertilizers and boosting plant growth yield under water conditions. This study used a factorial experimental design to investigate effects oak leaf extract, biofertilizer, soil containing powder biochemical parameters four tomato genotypes throughout pre-flowering pre-fruiting stages development. experiment had two components. first component represented (two sensitive tolerant), while second treatment group, which included irrigated plants (SW), untreated stressed (SS), treated with (SOS), extract (SOES), biofertilizers (SOBS). When compared or control plants, drought treatments SS, SOS, SOES, SOBS conditions at their combination significantly lowered shoot length (12.95%), total fruit weight per (33.97%), relative content (14.05%), chlorophyll (26.30%). reduction values (17.58%), fresh (22.08%), (42.61%) were larger in tolerant genotypes, recorded percentages 8.36, 8.88, 25.32% length, weight, plant, respectively. Root root dry SOBS, other hand, increased comparison plants. Tomato fruits from considerably higher levels titratable acidity, ascorbic acid, phenolic compounds than during all stages. Under conditions, addition soil, biofertilizer improved leaves genotypes. Furthermore, lipid peroxidation was lower SOES susceptible In conclusion, application demonstrated slight decrease some morpho-physiological physicochemical traits SS treatment. However, can be described as novel agricultural practices because they are low-cost, easy use, time-consuming, meet growing demands sector by providing environmentally sustainable techniques enhancing resistance stress. usage crude powder, arbuscular mycorrhizal fungus should investigated further
