Special Issue Information

Dear Colleagues,

Vegetables play an increasingly crucial role in ensuring food and nutritional security by serving as vital sources of nutrients that are necessary for healthier diets. Vegetable farming involves a diverse range of crops, leading to significant variations in the applied agricultural methods. Modern hybrid species are distinguished by higher yields, a better appearance, easier handling, and improved marketability, often at the expense of nutritional value.

Global shifts in attitudes towards sustainability and a reduced human impact on the environment, together with the projected population growth and climate change, motivate technological development that is aimed at ensuring global food and resource security. With the rapid development of technology and science, the application of new technologies becomes extremely important in agriculture. The parameters of the handling and cultivation environment enable R&D advancements of crops through the specific impacts of research on plants’ growth, development, and metabolism. In addition, the exploration of plants’ physiological characteristics and the advancement of genetic knowledge of cultivation methods focusing on species-specific plant functioning are enabled. This Special Issue of Plants will highlight insights on cultivation methods that are applied in the open field or in a closed environment, seeking to create strategies for combating hidden hunger.

Yours faithfully,

Dr. Giedrė Samuoliené

The application of biostimulants in vegetable cultivation has emerged as a promising approach to enhance the nutritional quality of crops, particularly in controlled environment agriculture and soilless culture systems. In this study, we employed a rigorous methodology, applying various biostimulants amino acids, Plant Growth-Promoting Rhizobacteria (PGPR), fulvic acid, chitosan, and vermicompost along with mineral fertilizers, both foliar and via the roots, to soilless greenhouse tomatoes during spring cultivation. The experiment, conducted in a coir pith medium using the ‘Samyeli F1’ tomato cultivar, demonstrated that plants treated with biostimulants performed better than control plants. Notable variations in nutritional components were observed across treatments. PGPR had the best effects on the physical properties of the tomato fruit, showing the highest fruit weight, fruit length, equatorial diameter, fruit volume, fruit skin elasticity, and fruit flesh hardness while maintaining high color parameters L, a, and b. PGPR and fulvic acid demonstrated significant enhancements in total phenolics and flavonoids, suggesting potential boosts in antioxidant properties. Amioacid and vermicompost notably elevated total soluble solids, indicating potential fruit sweetness and overall taste improvements. On the other hand, vermicompost stood out for its ability to elevate total phenolics and flavonoids while enhancing vitamin C content, indicating a comprehensive enhancement of nutritional quality. In addition, vermicompost had the most significant impact on plant growth parameters and total yield, achieving a 43% increase over the control with a total yield of 10.39 kg/m2. These findings underline the specific nutritional benefits of different biostimulants, offering valuable insights for optimizing tomato cultivation practices to yield produce with enhanced health-promoting properties.
