Saccorhiza polyschides Extract as Biostimulant for Reducing Salt Stress Effect in Common Bean Crops

Published: June 20, 2024

Salinity stress emerges as an important menace to global food security, particularly affecting susceptible crops such common bean plants (Phaseolus vulgaris L.). The disruption of ion balances caused by salt withing cells reduces water and nutrient absorption, hampers growth productivity. Sacchorhiza polyschides, a brown macroalga rich in essential elements, macrominerals, has drawn attention natural biostimulant, being potential remedy bolster crop resilience against stress. This study delves into the effect extracts polyschides (SPE) across varying concentrations (1%, 2%, 5%) under (68.4 mM NaCl) conditions. Two different methods application were used: spraying aerial part plant or irrigation together with watering solution. effects both systems studied on parts plants. SPE exhibited significant enhancements morphological parameters, chlorophyll content, carbon-nitrogen activities, antioxidant enzymatic system alongside increasing osmolyte accumulation, compared salt-stressed without biostimulation. Moreover, reduced reactive oxygen species (ROS) levels stress, mitigating lipid peroxidation. 2% 5% applied showed most results parameters analyzed. By shedding light underlying science behind this biostimulant effect, research underscores enhance augment production salt-challenged environments.

Phycoremediation of Potato Industry Wastewater for Nutrient Recovery, Pollution Reduction, and Biofertilizer Production for Greenhouse Cultivation of Lettuce and Celery in Sandy Soils

International Journal of Plant Biology, Journal Year: 2024, Volume and Issue: 15(3), P. 652 - 672

Microalgae-based wastewater treatment offers an eco-friendly opportunity for simultaneous nutrient recovery and biomass generation, aligning with the circular bioeconomy concept. This approach aims to utilize nutrients of potato industry (PIW) algal growth while mitigating environmental impact this industrial byproduct. study focused on cultivating three cyanobacterial strains, Anabaena oryzae, Nostoc muscorum, Spirulina platensis, in PIW synthetic media 30 days assess feasibility. Growth performance was monitored by measuring chlorophyll content, dry weight (DW), optical density (OD), pH at 3-day intervals. The high-performing from laboratory findings formulated into a biofertilizer, which then evaluated controlled greenhouse experiment celery lettuce plants. biofertilizer replaced conventional NPK mineral fertilizers different levels (25%, 50%, 75%), control group received 100% chemical fertilizer. results showed favourable all cyanobacteria strains their mixture throughout experiment. mixed followed platensis exhibited highest rates, achieving contents 3.75 2.30 µg·mL−1, DWs 1.79 g·L−1 1.63 g·L−1, ODs 0.41 0.38, respectively, surpassing other treatments. biofertilizers, Spi-PIW (Spirulina + wastewater) Cyano-PIW (mixed culture+ wastewater), significantly enhanced plant height, root stem lengths, number leaves per compared group. These treatments also improved contents, as well macro- micronutrient levels, two crops. Additionally, application these biofertilizers certain sandy soil properties, i.e., pH, total organic matter, nitrogen, phosphorus, potassium. In conclusion, utilizing substrate producing high-quality liquid bio-organic holds potential reducing recommended fertilizer doses 25–50% growth, providing environmentally friendly approach.
