Special Issue Information

Dear Colleagues,

Concepts of horticultural science are utilized for the production, enhancement and marketing as well as the improvement of human and animal life on Earth. With an arable land of 16.9 million hectares, and a world population that will increase from the current 7 billion to 9.5 billion by the year 2050, new technological advancements in horticulture have emerged as a major focus in crop production.

The field of horticulture has grown exponentially in recent years. The future of horticulture holds different possibilities for progress in terms of new technologies and precision agriculture, sustainable practices, urban agriculture, climate resilience, consumer preferences, health and wellness and biodiversity conservation. In the context of promoting efficient and sustainable crop production systems, that require less inputs and biodegradable wastes as well as do not compromise productivity and quality, we present this Special Issue with the aim to provide insights on the following areas:

  • The latest scientific results on innovative and smart technologies, such as vertical farming and indoor cultivation, agrovoltaics, artificial intelligence in agriculture, agroecology and automation and measurement of fertigation, all of which promote precision management in horticulture;
  • Other advances in soilless cultivation, with new opportunities to improve plant growth and reduce water and carbon footprint as well as improve nutrient efficiency in consonance with an environmental objective;
  • New substrates as a source of nutrients, substrates for green roofs and vertical gardens, new alternative substrates to peat and the study of physical, chemical, and biological properties of substrates, substrate disinfection and recovery and the reuse of nutritional solutions that can improve horticulture;
  • New fertilizers, such as biofertilizers, fortifiers and/or biostimulants, techniques for increasing efficiency in the use of fertilizers, use of compost and vermicompost, precision fertilization, new varieties adapted to climate change conditions, and new control techniques of plagues and diseases;
  • Importance of bioactive compounds in horticultural products, novel plant products for food, pre-harvest applications to improve post-harvest quality and the revaluation of plant resources for food as a sustainable link of the food chain.

Water scarcity is a significant global risk affecting health, food security, economic development, social stability, environmental sustainability, and climate change adaptation. Implementing deficit irrigation strategies can improve water efficiency and agricultural resilience. Spain, particularly the Region of Murcia, has pioneered apricot cultivation, with the ‘Mirlo Rojo’ variety known for its high productivity, Sharka virus resistance, and exceptional organoleptic qualities. This study evaluates the effects of regulated deficit irrigation (RDI) on the quality, antioxidant activity, fatty acid profile, and volatile compounds of ‘Mirlo Rojo’ apricots. Four irrigation treatments (100% ETc, 60% ETc, 33% ETc, and 0% ETc) were tested during the final growth stages in May 2023. Results showed no adverse effects on the evaluated parameters. RDI treatments increased total soluble solids, glucose, and fructose content, improving maturity and sweetness indices. RDI also enhanced phenolic content and antioxidant activity, optimizing water use without compromising fruit quality and bioactive compounds. Full article

Food security is threatened by climate change and associated abiotic stresses that affect the flowering stage and the biochemistry of flowers and fruits. In tomato, managed insect pollination and grafting elite tomato varieties onto robust rootstocks are widely practiced commercially to enhance tomato crop profitability, particularly under suboptimal conditions. However, little is known about rootstock–pollinator interactions and their impact on the chemical composition of fruit. In this study, a commercial tomato F1 hybrid (Solanum lycopersicum L.) was self-grafted and grafted onto a set of experimental rootstocks and cultivated under optimal and saline (75 mM NaCl) conditions in the presence of managed bumblebee pollinators (Bombus terrestris). The number of visits (VN) and total visiting time (TVT) by pollinators to different grafted plants were monitored through an RFID (radio-frequency identification) tracking system, while targeted metabolites (hormones, sugars, and organic and amino acids) and mineral composition were analyzed in the fruit juice by UHPLC-MS and ICP-OES, respectively. Pollinator foraging decisions were influenced by the rootstocks genotype and salinity treatment. Experimental rootstocks predominantly increased pollinator attraction compared to the self-grafted variety. Interestingly, the pollinator parameters were positively associated with the concentration of abscisic acid, salicylic acid, malate and fumarate, and tyrosine in salinized fruits. Moreover, a high accumulation of sodium was detected in the fruits of the plants most visited by pollinators, while rootstock genotype-specific responses were found for nitrogen and potassium concentrations. In addition to the known effect on yield, these findings underscore the synergic interactions between rootstocks, pollinators, and environmental stressors on tomato fruit composition. Full article

Organic fertilization is gaining importance as an alternative to chemical fertilization. However, the effects of organic products on crop quality need to be characterized, especially in biochar and derived products. Therefore, the effect of enriched biochar supplied with an organic fertilizer (biochar) on the yield and nutritional compounds of artichoke (Cynara cardunculus var. Scolymus) heads was analyzed and compared to inorganic conventional fertilization (control). For this purpose, the number of fruits and their weights were determined, along with the nutritional properties of artichoke heads, such as mineral content, fatty acids, phenolic compounds, and flavonoids. The results showed that biochar increased crop yield, as registered by the higher number of marketable or commercial artichokes compared to the control. Additionally, biochar-treated plants exhibited significantly higher contents of Ca, Mg, and S in the artichoke heads, but they had a decreased content of Co, Cu, and Zn. The fatty acid content in the biochar-treated artichokes was also significantly higher, primarily due to the presence of palmitic acid. Conversely, the contents of phenolic compounds (e.g., flavonoids) were negatively and significantly affected by the application of biochar. In conclusion, the application of biochar as a soil amendment in combination with organic matter for growing artichokes in the semiarid Mediterranean area (e.g., Murcia Region) favored an increase in yield without compromising its nutritional composition. Further developments to establish protocols for the extended use of biochar in this agri-food production area are guaranteed. Full article

Wounding stress stimulates secondary metabolism and induces the phytochemical accumulation of fresh-cut fruit and vegetables. This research aims to study the biosynthesis of secondary metabolites in citrus peel by-products after different wounding intensities. Orange, grapefruit, and lemon peels were cut into rectangular shapes of 8.5 × 2 cm (CTRL), 1 × 1 cm dices (D), and 0.25 cm grates (G). Samples were stored at 15 °C and 65% relative humidity. Their total phenolic content (TPC), total antioxidant capacity (TAC), and individual organic and phenolic compounds were analyzed after 0, 4, 8, 24, 28, and 36 h. The results showed that the metabolite content decreased with the incubation time, so it is recommended to sample by-products between the first 8 h to achieve the maximum content. Grating, the most severe abiotic stress, was not a suitable technique to induce the synthesis of biocompounds because it allowed the full recovery of flavedo, but partial of albedo. However, it was different for CTRL and D, whose TPCs were ~170 and ~200%, ~98 and ~78%, and ~8 and ~36% higher for orange, grapefruit, and lemon, respectively, compared to G. A principal component analysis confirmed differences between the fruit species and cutting shapes combining all factors. Wounding citrus peels induces the accumulation of phytochemical compounds, but the layer of peel recovered in the cut is crucial in the concentration of phytochemicals extracted. It could be an innovative tool to revalorize these inedible parts of citrus, but further research is still needed. Full article
