Adaptive detection of volunteer potato plants in sugar beet fields [PDF]

Volunteer potato is an increasing problem in crop rotations where winter temperatures are often not cold enough to kill tubers leftover from harvest. Poor control, as a result of high labor demands, causes diseases like Phytophthora infestans to spread ...

Management Strategies and Agricultural Calendars for Forage Production in Semi‐Arid Brazil Using AquaCrop

Irrigation and Drainage, EarlyView.
ABSTRACT Forage production in semi‐arid regions of Brazil is limited by water deficit. This study aimed to identify the most adapted and efficient production systems and define their agricultural calendars for the semi‐arid region of Brazil. Twenty‐nine production arrangements that included different cropping conditions, plant density, plant cycles ...

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

JSFA 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 ...
