Abstract In recent decades, the demand for vegetables has increased significantly due to blooming global population. Climate change affected vegetable production by increasing frequencies and severity of abiotic biotic stresses. Among stresses, drought salinity are major issues that possess severe threats on production. Many (e.g., carrot, tomato, okra, pea, eggplant, lettuce, potato) usually sensitive salt stress. The defence mechanisms plants against stress have been extensively studied in model plant species field crops. Better understanding susceptibility stresses will help towards development more tolerant genotypes as a long-term strategy these However, intensity challenges also warrants immediate approaches mitigate enhance short term. Therefore, this review enlightens updated knowledge responses (physiological molecular) potentially effective strategies Moreover, we summarized different technologies such seed priming, genetic transformation, biostimulants, nanotechnology, cultural practices adopted under We propose conventional breeding, engineering, crop management should be combined generate resistance cultivars adopt smart cultivation sustainable changing climate.

Silicon as a Smart Fertilizer for Sustainability and Crop Improvement

Biomolecules, Год журнала: 2022, Номер 12(8), С. 1027 - 1027

Silicon (Si), despite being abundant in nature, is still not considered a necessary element for plants. Si supplementation plants has been extensively studied over the last two decades, and role of alleviating biotic abiotic stress well documented. Owing to noncorrosive nature sustainability elemental Si, fertilization agricultural practices gained more attention. In this review, we provide an overview different smart fertilizer types, application fertilizers agriculture, availability fertilizers, experiments conducted greenhouses, growth chambers, open fields. We also discuss prospects promoting as among farmers research community sustainable agriculture yield improvement. Literature review empirical studies have suggested that Si-based expected increase future. With potential nanotechnology, new nanoSi (NSi) applications may further use efficiency fertilizers. However, general awareness scientific investigation NSi need be thoughtfully considered. Thus, believe can insight into promote crop

The aim of the current study was to isolate endophytes from roots Rhazya stricta and assess their potential improve growth drought-stressed sunflower seedlings. role isolated endophytic fungus initially screened by using two rice varieties (mutant cultivar Waito-C: Gibberellins deficient; Dongji byeo: Gibberellins-producing normal cultivar). A significant (p < 0.05) increase in various attributes both associated with one isolates i.e., N4 noticed. Furthermore, tested for its improving agronomic sunflowers under drought stress. symbiotic association significantly improved host protection PEG-induced mitigation N4-associated seedlings can be linked regulation phytohormones, stress-related metabolites, low-molecular-weight proteins sugars, scavenging reactive oxygen species (ROS). Microscopic analysis revealed that potent fungal strain consisted thin hyaline hyphae, forming dense olive-green mycelia (4–5 cm dm) black flask-shaped fruiting bodies. Based on ITS sequence homology phylogeny, identified as Fusarium proliferatum (MG251448). results this concluded phytohormone-secreting endophyte crop productivity dry areas where stress is main challenge faced crops.

Tomato (Solanum lycopersicum L.) is an important vegetable crop around the world, and water scarcity soil salinization are two major unfavorable factors limiting fruit yield quality of greenhouse tomato in arid semi-arid regions. The application exogenous silicon has been reported to enhance under salt or drought stress, but its effect combined salt-drought stress remains unclear. A two-season (autumn 2021 spring 2022) experiment was conducted with three irrigation levels (I1, 90%−100% θf, where θf field capacity; I2, 70%−80% θf; I3, 50%−60% θf), salinity (S0, 0.1%, g/g; S1, 0.4%, g/g) rates (T0, 0 mM; T1, 2.4 mM) explore their effects on leaf content, photosynthetic parameters, yield, nutrient productivity (WP), nitrogen uptake utilization, (NWP) economic benefit drip-irrigated tomato. results showed that deficit exerted significant inhibiting water-nitrogen productivity, inhibition alleviated by application, which increased content 67.0%, net rate (Pn) 25.3%, 12.3%, WP 11.9%, 10.0% (titratable acids) - 27.4% (soluble sugars) NWP 9.2% 26.1% average. average over growing seasons 66.01, 54.29 44.31 t ha−1 I1, I2 71.9%, 65.2% 63.0%, Pn 11.1%, 12.9% 7.6%, 12.8%, 16.2%, 8.1% at levels, respectively. Plant (NU) partial factor (NPFP) use efficiency (NUE) tended decrease increasing level, while improved NUE 3.9% 2.2% NPFP 13.8% 11.7% seasons, Silicon significantly profit 24.3% 17.7% autumn 2022, According principal component analysis, I1T1S0 ranked first both seasons. correlation matrix positively correlated Pn, stomatal conductance, WP, NU, NUE, NPFP, profit, it had negative NWP. In conclusion, can improve enhancing capability drought-stressed salt-affected conditions.
