Drought is a significant environmental stressor that induces changes in the physiological, morphological, biochemical, and molecular traits of plants, ultimately resulting reduced plant growth crop productivity. Seaweed extracts are thought to be effective mitigating effects drought stress on plants. In this study, we investigated impact crude extract (CE), polysaccharides (PS) derived from brown macroalgae Fucus spiralis (Heterokontophyta, Phaeophyceae) applied at 5% (v/v) 0.1% (w/v) respectively radish plants Raphanus sativus L. subjected varying levels stress, specifically 80% field capacity (FC) for no 60% FC moderate 40% severe stress. Our examination parameters, along with physiological biochemical characteristics, revealed both CE PS increased fresh weight over control by 47.43% 64% 12.5% 38% respectively. Under (40% FC), application decreased proline content leaves 23.45% 6.46% comparison control. Furthermore, treatment caused an increase alkaline phosphatase urease activity soil 182.5% 34.6% treatments led sugar total phenolics levels. Notably, lipid peroxidation was stressed treated PS, yielding lower concentrations (3.75 nmol MDA.g− 1 FW FC). Overall, F. interacted through several mechanisms using various compounds mitigate negative These results demonstrate seaweed could adopted integrated production systems boost food productivity under harsh climatic conditions.

Changing climates threaten crop growth and fodder yields in dryland farming. This study assessed two radish genotypes (LINE 2, ENDURANCE) under three water regimes (W1 = well-watered, W2 moderate stress, W3 severe stress) leaf harvesting options over seasons (2021/22 2022/23). Key findings revealed that regime significantly (P < 0.05) affected WUE, with yielding (4.71 kg ha-1 mm-1) higher values. The combination of LINE 2 biomass were reduced by ≈ 60.09% 2021/22 71.06% 2022/23, whereas ENDURANCE declined 63.9% 53.33%. Tuber yield was highest W1 W2, 59 t (W1) 48 (W2). Generally, micronutrient concentration (iron, zinc, β-carotene vitamin C). For example, improved E key showed human dietary for women children can be met. exceeded E, iron, zinc recommendations all ages. similar CP W1, indicating stress sustain yields. These highlight the importance strategic management food security, while meeting nutritional needs water-scarce regions.
