A comprehensive review on rice responses and tolerance to salt stress

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: March 31, 2025

The challenge of salinity stress significantly impacts global rice production, especially in coastal and arid regions where the salinization agricultural soils is on rise. This review explores complex physiological, biochemical, genetic mechanisms contributing to tolerance (Oryza sativa L.) while examining agronomic multidisciplinary strategies bolster resilience. Essential adaptations encompass regulation ionic balance, management antioxidants, adjustments osmotic pressure, all driven by genes such as OsHKT1;5 transcription factors like OsbZIP73. evolution breeding strategies, encompassing traditional methods cutting-edge innovations, has produced remarkable salt-tolerant varieties FL478 BRRI dhan47. advancements this field are enhanced including integrated soil management, crop rotation, chemical treatments spermidine, which through antioxidant activity transcriptional mechanisms. Case studies from South Asia, Sub-Saharan Africa, Middle East and, Australia demonstrate transformative potential utilizing varieties; however, challenges persist, polygenic nature tolerance, environmental variability, socioeconomic barriers. highlights importance collaborative efforts across various disciplines, merging genomic technologies, sophisticated phenotyping, inclusive practices foster climate-resilient sustainable cultivation. work seeks navigate complexities its implications for food security, employing inventive cohesive confront posed climate change.

Investigating the Impact of Tillering on Yield and Yield-Related Traits in European Rice Cultivars

Agriculture, Journal Year: 2025, Volume and Issue: 15(6), P. 616 - 616

Published: March 13, 2025

Optimizing rice productivity is crucial for global food security, especially in Mediterranean environments. This study investigated the influence of tillering capacity on yield and other agronomic traits nine European cultivars over two seasons (2021–2022). A split-plot design was used with as main factor five levels: stems (Mn), primary (T1), secondary (T2), tertiary (T3), quaternary (T4) sub-factors. The grain yield, total dry matter, harvest index, 1000-grain weight, number were measured. Significant differences revealed among cultivars, levels, their interaction all traits. Mn T1 consistently outyielded later tillers, Ronaldo’s achieving 4.71 t ha−1. Mare Olympiada displayed highest average yields (1.52 ha−1) through balanced resource allocation across tillers. Strong correlations between levels (R2 = 0.73) demonstrate that early tillers significantly enhance productivity. We conclude optimizing tiller productivity—rather than maximizing numbers—should be prioritized breeding programs. Cultivars combining vigorous development efficient partitioning offer most promising approach improving

The combination of sulfur and nitrogen fertilization has a direct impact on the recovery process of degraded pastures in tropical climates

Grassland Science, Journal Year: 2025, Volume and Issue: unknown

Published: March 27, 2025

Abstract The present study aimed to determine the effect of combining sulfur (S) with nitrogen (N) in pastures Marandu palisade grass ( Urochloa brizantha [A. Rich.] R.D. Webster) at an early stage degradation. experiment was conducted São Luís de Montes Belos (located Brazilian Cerrado region), starting October 2019 and ending September 2021. design used a randomized block arranged factorial scheme, where plots were made up S doses subplots N doses, four replications. Five (0, 65, 130, 195 260 kg/ha) three 100 200 assessed. Doses promote increases green ground cover rate color index. combined application kg/ha 150 results average forage productivity 15.59 Mg/ha, representing 21.93% increase biomass production previously degraded pastures. This demonstrates that interaction between positively influences recovery tropical climate regions, as evidenced by improvement production.

Evaluation and Optimal Design of a Balanced Diet

Mathematics, Journal Year: 2024, Volume and Issue: 12(17), P. 2637 - 2637

Published: Aug. 25, 2024

Malnutrition has led to growth retardation in many adolescents and health deterioration adults all over the world. Recently, there been increasing attention on balanced diets as a preventive measure. This study evaluates daily diet of student, aiming optimize amino acid score (AAS) across three meals per day. By using criteria constraints, we established single-objective nonlinear programming model, maximizing AAS objective function. The model was solved by simulated annealing algorithm, obtained that is both high AAS. helps raise awareness about individual nutritional needs provides guidance for dietary structure improvements, thereby contributing global public enhancement.
