Special Issue Information

Dear Colleagues,

Horticulture is fundamental to world subsistence, and it plays a structural role at the cultural, social, and economic levels of the world. Each horticultural species requires optimal climatic and meteorological conditions for its development, yield, and quality of its products. Climate change may therefore exert a significant impact on the subsistence of these horticultural crops. According to various records, historical trends have already indicated an increase in average temperatures and changes in rainfall patterns. In addition, various climate scenarios have suggested that these conditions will intensify.

It is crucial to understand the evolution of the climate and the possible impacts it has, and will have, on horticultural crops. Therefore, this Special Issue entitled “Enhancing Adaptation of Horticultural Crops to Climate Change Challenges” welcomes studies that highlight the evolution of the climate, the climatic needs of horticultural crops, the possible impacts of climate change on horticulture, and adaptation and mitigation measures in the face of climate challenges.

Applying nitrogen fertilizers in agriculture can cause uncontrolled gas emissions, such as N2O and CO2, leading to global warming and serious climate changes. In this study, we evaluated the greenhouse gas emissions (GHGs) that are concomitant with applying different rates of N fertilization, i.e., 50, 75, 100, and 125% of the recommended dose (727 kg N ha−1) for two cultivars (Balady and Sids-40) of Allium sativum L. grown under three planting dates (15 September, 1 October, and 15 October). For this purpose, two field experiments were carried out during the two growing seasons of 2020/2021 and 2021/2022. Treatments were arranged in a split–split plot design with three replicates: planting dates were set up in the main plots, nitrogen levels were conducted in the submain plots, and garlic varieties were in the sub-subplots. The obtained results can be summarized as follows: Planting on 15 September significantly increased vegetative growth parameters (i.e., plant height, leaves area, number of leaves plant−1, and leaves dry weight) and total bulb yield, in both seasons. The application of the highest rate of N (125%) gave significantly higher records for vegetative growth parameters, while the 75% nitrogen treatment appeared to give the highest total bulb yield in both seasons. The means of plant growth characteristics and total bulb yield were significantly increased by the cultivation of the Balady cultivar. In addition, the results show that GHGs were positively correlated with increasing the rate of N fertilization. It could be recommended that planting on 15 September and fertilizing with 75% N fertilizer from the recommended dose for Balady cultivar achieve maximum yield and its components. Full article

The renaissance in urban agriculture is driven by its contributions to fostering more sustainable, healthy, and renaturalized cities. While urban gardens are usually designed to improve food security or serve social purposes, they also offer additional benefits. The aim of this research is to study the urban allotment gardens in Valladolid, Spain, highlighting their capacity to support low-income populations and their potential contribution to urban cooling. As a result of research in twelve plots across four gardens, we found that crop selection in Valladolid aligns with broader urban gardening trends in the Global North, with production adapted to limited plot space and varying significantly by season. In addition, we observed that urban allotment gardens provide more stable and cooler temperatures compared to urban gray spaces, although not as significantly as urban parks. The cooling effect was most pronounced during the summer, a season with the highest number of crops and the warmest temperatures. The study identified that greater crop cover above soil had a more significant cooling effect at the plot level. Surprisingly, crop abundance and crop diversity showed a weak correlation with cooling benefits. As a complement, survey questionnaires conducted with gardeners revealed their awareness of climate change and its perceived direct threat to their crops, health, and city. The future concerns of gardeners regarding the availability of water for both crop growth and the development of urban allotment gardens are emphasized. The findings provide results on self-produced food, urban cooling, and the opinion of gardeners, underscoring the multifunctional contributions of urban gardens to cities. Full article
