Adjustment of a turbulent boundary layer to a 'canopy' of roughness elements

open access: yes, 2003
A model is developed for the adjustment of the spatially averaged time-mean flow of a deep turbulent boundary layer over small roughness elements to a canopy of larger three-dimensional roughness elements.

Integrated characterization of Greek fennel genotypes through morpho‐agronomical characteristics, yield components and phytochemical compounds

open access: yesJSFA reports, Volume 5, Issue 3, Page 91-103, March 2025.
Abstract Background Fennel (Foeniculum vulgare Mill.) is a widely cultivated vegetable and aromatic‐medicinal plant. In this research, field studies assessed 12 fennel genotypes of diverse origin, comprising 10 Greek accessions and two European commercial varieties, focusing on their morpho‐agronomical traits, phenolic compounds and antioxidant ...

The Collembola fauna of lrish forests – a comparison between forest type and microhabitats within the forests

open access: yesSoil Organisms
Forest is the climax vegetation for most of Ireland. Yet, at the beginning of the twentieth century, because of deforestation, only 1.4 % of the land area was afforested.

Synergistic effects of maize defoliation and common bean relay cropping in Western Ethiopia

open access: yesJSFA reports, EarlyView.
Abstract Background Maize defoliation is practiced to enhance crop management by improving light penetration, nutrient allocation, controlling weeds, and providing supplementary feeds for livestock. A rapid decline in soil fertility and low crop yields associated with maize‐based monocropping has prompted the recent introduction of maize common bean ...

Effects of deficit irrigation and biostimulants on melon productivity and quality in semi‐arid conditions

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Water scarcity and soil salinization are major constraints to irrigated agriculture in semi‐arid regions, affecting crop productivity and fruit quality. Combining deficit irrigation with biostimulant application has emerged as a promising strategy to improve water use efficiency and plant stress tolerance.

Assessing plant water status: Part 1 – Classical methods

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract As a result of the changing climate, water scarcity poses a significant threat to crop and pasture production. Although soil water content can indicate drought, its measurements often provide limited spatial resolution and are weakly correlated with plant water status, producing misleading drought assessments.

Assessing plant water status: Part 2 – Non‐destructive and remote sensing approaches

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Precise, real time and non‐destructive assessment of plant water status is important for advancing plant physiological understanding, optimizing water usage, improving crop resilience and supporting precision agriculture in the face of increasingly variable climatic conditions.
