Seaweed (Ascophyllum nodosum L.) extract improved the physiology, promoted the vegetative development and yield of grapevines under arid/semiarid condition

A two-year study demonstrates that foliar application of *Ascophyllum nodosum* seaweed extract significantly improves the physiology, vegetative growth, and yield of 'Alphonse Lavallée' and 'Prima' grapevines under arid/semiarid continental climate conditions, making it a recommended precision viticulture strategy for mitigating heat and drought stress.

Nutrient-to-price ratios of commonly consumed foods and modelled dietary guideline costs in Bangkok, Thailand

This study demonstrates that in Bangkok, Thailand, selecting specific foods based on nutrient-to-price ratios within the framework of existing dietary guidelines can significantly reduce the cost of a healthy diet—by up to 69.8%—making it more affordable for low-income populations without altering recommended serving structures.

Enzymatic tailoring of potato proteins establishes multiscale structure–functionality relationships for plant-based meat analogue texture formation

This study demonstrates that enzymatic tailoring of potato proteins, through mechanisms such as crosslinking or controlled hydrolysis, enables precise multiscale control over gel network formation to rationally engineer the texture of plant-based meat analogues.

Biochar-immobilized Burkholderia pyrrocinia bacterial agent alleviates cadmium stress in pepper throughout the growth cycle: physiological and transcriptomic insights into growth promotion and decreased cadmium accumulation

This study demonstrates that a biochar-immobilized *Burkholderia pyrrocinia* agent effectively alleviates cadmium stress and enhances growth in pepper plants throughout their lifecycle by improving physiological resilience and upregulating key molecular pathways involved in cadmium sequestration, hormone biosynthesis, and oxidative stress defense.

Impact of small-scale irrigated vebetable production on household food and nutrition security

This study in Ethiopia's Kombolcha district demonstrates that participation in small-scale irrigated vegetable production significantly improves household food and nutrition security, as evidenced by a Propensity Score Matching analysis showing substantial increases in dietary diversity and food consumption scores among participating farmers compared to non-participants.

Establishing Lethal and Growth Reduction Doses of Fast Neutron Irradiated Cowpea [Vigna Unguiculata (L.) Walp.]

This study determined the median lethal (LD₅₀) and growth reduction (GR₅₀) doses of fast neutron irradiation for two cowpea varieties, revealing that SAMPEA 21 is more radiosensitive than SAMPEA 20T and providing essential genotype-specific benchmarks to optimize mutation breeding protocols.

Efficiency of timber harvesting with a harvester in fir stands with designated and undesignated thinning

This study found that while harvesting fir stands with undesignated thinning takes approximately 12% longer than with designated thinning due to extended machine movement and cut planning, the operator's mental workload and concentration levels remain comparable in both scenarios.

Emerald ash borer specific dsRNA demonstrates short-term persistence in soil and minimal effects on collembolans

This study demonstrates that emerald ash borer-specific dsRNA exhibits short-term persistence in soil and causes minimal adverse effects on non-target collembolans, with laboratory bioassays showing no negative impacts on survival or growth and field data indicating only transient fluctuations in abundance.

Integrated phosphorus management strategy improves maize phosphorus use efficiency by coordinating root-zone phosphorus availability and root architecture under reduced-P drip irrigation

This study demonstrates that an integrated phosphorus management strategy combining deep banded P placement with γ-polyglutamic acid under reduced-P drip irrigation significantly enhances maize phosphorus use efficiency and maintains yield in calcareous soils by synchronizing root-zone phosphorus availability with optimized root architecture.
