Special Issue Information

Dear Colleagues,

The human population is continually expanding. The United Nations estimates that the world population will grow by nearly 4 billion people in 2100, which will exceed 11 billion people. This fact makes it necessary to change the current cultivation paradigm in order to feed a constantly growing population. However, it is not enough to just produce more; the production practices must be sustainable and environmentally friendly.

Alongside the problem of overpopulation is the added, current problem of malnutrition. It has been reported that a large part of the population lacks vitamins or has anemia due to a lack of iron. Therefore, it is necessary to search for new eco-friendly food production techniques that provide foods with better nutritional quality and that allow food to be supplied to the entire population.

Therefore, we are pleased to announce this Special Issue on “Agronomic Practices for Improving Growth, Quality, and Yield of Vegetables”, which will be a compilation of high-level scientific research, reviews, and high-level opinion articles. This Special Issue will address new and sustainable cultivation strategies that allow for improved vegetable production and quality.

Increasing soybean productivity can be achieved by treating seeds with biostimulants. To this end, an investigation was conducted into the potential of a formulation prepared with clove es-sential oil (CEO) diluted in soybean oil for seed treatment. Soybean seeds were treated with CEO concentrations between 0.5 to 3.0 mL/L, and subjected to germination, vigor, and sanity analyses. The CEO at 1.6 mL/L exhibited favorable outcomes regarding germination, root length, and re-duced fungal infection. In this way, a two-crop field experiment evaluated soybean seeds treated with CEO at 1.6 mL/L. Soybean seeds treated with CEO in the field in 2021/2022 were not different from the controls. However, in 2019/2020, there was a higher percentage of emergence, nodulation, and production of 749 kg/ha more than in the industrial treatment. These results highlight the potential use of CEO as a biostimulant. Full article

Auxin transport is regulated by the AUX1/LAX, PIN, and ABCB gene families, controlling the distribution of auxin and ultimately fruit curving in cucumbers. However, studies on the differential expression of these auxin transporters and their roles in fruit curving are limited. In this study, we identified 36 auxin transporters from cucumber, including CsLAX1–7, CsPIN1–10, and CsABCB1–19. Basic characteristic analysis revealed that all CsLAX proteins were conservative, and a C-terminal NPNTY motif was found in CsPIN1–4/7–10. CsABCB1/5/11/14/17 were categorized as half-size transporters. Phylogenetic analysis revealed a genetic relationship between auxin transporters in Arabidopsis and cucumber. Exogenous auxin treatment on fruits and qPCR analysis indicated that differential expression patterns of auxin transporters control cucumber fruit curving. Co-expression analysis indicated that CsPIN1 and CsLAX2 were substantially negatively correlated, and they displayed opposite expression patterns in curved fruits. A proposed model suggested that CsLAX2 transports extracellular auxin to the convex side of the fruit; however, CsPIN1 inhibits auxin efflux at the same location. This leads to uneven auxin distribution that results in cucumber fruit curving. Full article
