Special Issue Information

Dear Colleagues,

Citrus plants are among the world’s most economically important crops. A pivotal aim in modern citriculture is to improve fruit quality using agronomic techniques. Sustainable innovations include fertilizer application and irrigation scheduling, flower and fruit management, training and pruning techniques, pest and weed control, biotic and abiotic stress control, and scion/rootstock combinations. This Special Issue will provide fundamental technical support for growers, with studies exploring how to improve the productive and qualitative traits of citrus plants. This Special Issue of Horticulturae will showcase innovative agricultural strategies for citrus cultivation. Plant and fruit response mechanisms will be analyzed through physiological, biochemical, or molecular approaches, with the aim of increasing citrus yield and fruit quality pre- and post-harvest.

Kind regards,
Dr. Giulia Modica
Dr. Alberto Continella

Cultivation practices such as fruit thinning and soil management with ground covers are commonly applied in Citrus orchards, yet their physiological impact on young trees remains poorly documented. This study evaluated the effects of manual fruit thinning and weed-control mesh on vegetative growth, fruit development, and leaf mineral composition of Citrus sinensis L. Osbeck cv. ‘Navelina’ grafted on Citrus macrophylla. A six-month field experiment was conducted in southeastern Spain under semi-arid Mediterranean conditions using six treatments that combined different soil coverage and subsurface drainage systems. After physiological fruit drop, trees were standardized to ten fruits per plant. Vegetative parameters (canopy and trunk dimensions), fruit growth (size, juice content), and foliar nutrient concentrations were monitored. Trees with ground cover showed significantly greater canopy expansion and juice yield compared to uncovered controls. A negative correlation between fruit number and canopy-to-fruit volume ratio highlighted the trade-off between vegetative vigor and fruit load. Foliar analysis revealed lower micronutrient concentrations (Fe, Mn, B, Zn) in uncovered trees, suggesting reduced nutritional status. These findings demonstrate that combining early thinning with weed-control mesh promotes vegetative vigor, improves juice yield, and enhances nutrient uptake, providing practical insights for optimizing orchard establishment and early Citrus productivity in water-limited environments.
