Introduction
Vegetable grafting is a recent innovation in vegetable cultivation that has a great potential for enhancing crop productivity and profitability under climate change scenarios, besides its potential to reduce the cost of cultivation.
Methods
The present strategic research focused on assessing the performance of grafted and non-grafted tomato cultivars (PHS-448 & Sahoo) in Naturally Ventilated Polyhouse (NVPH) and open field (OF) conditions.
Results and discussion
The results revealed that grafted tomatoes expressed significantly (p<0.05) higher values of growth parameters, i.e., leaf area and chlorophyll content, contributing to significantly higher total yield over non-grafted tomatoes. The grafted tomato cultivars, viz, PHS-448 and Sahoo, recorded an increased total yield of 36.65% and 46.7% respectively compared to the non-grafted ones. Growing grafted tomatoes under NVPH conditions increased yields by 63.79% due to an increase in pickings (by 3 to 5 times) compared to non-grafted tomatoes grown under open field conditions. The system productivity followed similar yield trends and revealed significant (p<0.05) variation across all picking days. The profitability analysis (gross and net monetary returns and benefit-cost ratio) showed that grafted combinations grown under NVPH are more profitable than the open field conditions and non-grafted ones, grown under both conditions. The multiple regression analysis revealed a strong correlation (R ² = >80) of yield with plant height, middle leaves chlorophyll, and leaf area, irrespective of the grafted and non-grafted combinations. The present investigation concluded that cultivating grafted tomatoes helps farmers achieve maximum productivity and profitability in both NVPH and open field conditions. However, a proper policy framework is necessary to promote and scale up grafted vegetable technology to enhance the profitability of vegetable growers in climate change scenarios.
... In addition, conventional farming practices, together with the use of chemical fertilizers and pesticides that were increasingly becoming popular farming methods partly explained by worsening environmental conditions linked to climate change (Demi and Sicchia, 2021;Kumar et al. 2022). These vegetable crops are exceedingly sensitive to climate change, particularly to increasing temperatures, which can directly impact their yield hence to address the challenges of climate change, it is crucial to develop vegetable varieties that are heat-resistant (Dumitru et al., 2023) Moreover, conventional farming practices are not sustainable in the long term (Panhwar et al. 2018). Though still in low quantities, unsafe chemical use practices pose serious occupational health and environmental consequences as well as food safety issues. ...
Improved governance arrangements are central in strengthening value chains with sustainable, resilient farming and healthy nutrition. This study explored governance arrangements important to the vegetable value chains in Food System Labs in Bahir Dar (Ethiopia) and Cotonou (Benin). The study collected data through face-to-face interviews from different actors including input suppliers, producers, processors, wholesalers, retailers and from different supporting institutions such as credit organizations in the vegetable value chains in the two regions. The paper uses descriptive analysis for quantitative data, content analysis for qualitative data, and the strengths, weaknesses, opportunities, and threats (SWOT) analysis method in the context of the indicator-based assessment framework to examine governance arrangements. Results indicate that multiple but also alternating modes of governance arrangements exist along the vegetables value chain. Spot market relations dominate at the successive stages of the value chain where different actors randomly interact at every transaction. Relational governance in terms of information sharing is notable among producers who attach high relevance to farmer associations as well as traders who largely trust and source information from amongst themselves. The value chains are typical of limited collaboration between actors coupled with weak processing skills. In addition, unconducive storage facilities undermine the potential of upgrading despite changing preferences and growing demand for vegetables. The study recommends development and strengthening of actor organizations such as cooperatives and associations, provision of an enabling environment where vegetable value chains can thrive, and national level efforts to develop post-harvest handling skills and infrastructure, as well as exploitation of last mile digitization initiatives to increase competitiveness of vegetable trade.
... Climate change and its associated stresses are the main problems in chili-producing countries, particularly Asia. The fluctuating weather patterns and unpredictable climate negatively affected the crops, first subjecting them to suffer from the heat and, subsequently, the heavy rainfall, resulting in a complete transformation of the climate conditions (Koundinya et al. 2018;Dumitru et al. 2023;Deng et al. 2024). Heavy rainfall caused widespread flooding throughout the chili-producing countries in Asia, including China, Indonesia, India, and Pakistan, and caused significant damage to the chili crops due to rotten plant occurrences (Hassan 2022; The World Bank 2022). ...
Chili pepper, widely recognized as a popular spice and an important cash crop worldwide, faces significant threats from climate change-related stress, particularly plant disease outbreaks. Emerging global diseases like Phytophthora blight, anthracnose fruit rot, and Ralstonia bacterial wilt threaten chili-producing countries, causing substantial annual yield losses. These major threatening diseases are difficult to control due to their widespread, extensive, and long-lived survival structures. Disease management practices rely on agrochemicals, leading to resistance to phytopathogens and environmental issues. Current research focuses on developing innovative, effective, chemical-free, and sustainable biosecurity strategies to address these challenges. Endophytes are plant endosymbionts that provide new insights for scientists due to their remarkable genome regulation to host plants. This review highlights the current state of emerging global diseases affecting chili pepper crops based on bibliometric analysis. We also focus on endophytes-mediated plant defense response as a sustainable solution for chemical pesticides. This review discusses the importance of omics-based technologies in deciphering the biochemical and molecular mechanisms of endophytes-mediated chili plant tolerance to various pathogens. A holistic approach of plant endophytes and multi-omics technologies can help develop effective mitigation strategies to prevent disease outbreaks for sustainable crop production and environmental restoration in the modern era of Agriculture 4.0 ‒ a green agricultural revolution.
... Horticultural crops with high irrigation requirements [8] are particularly vulnerable to reduced precipitation, a scenario exacerbated by climate change [9]. In this context, eggplant (Solanum melongena L.) is emerging among vegetables as a promising candidate for cultivation under water-stressed conditions [10,11]. ...
Background
The generation of new eggplant (Solanum melongena L.) cultivars with drought tolerance is a main challenge in the current context of climate change. In this study, the eight parents (seven of S. melongena and one of the wild relative S. incanum L.) of the first eggplant MAGIC (Multiparent Advanced Generation Intercrossing) population, together with four F1 hybrids amongst them, five S5 MAGIC recombinant inbred lines selected for their genetic diversity, and one commercial hybrid were evaluated in young plant stage under water stress conditions (30% field capacity; FC) and control conditions (100% FC). After a 21-day treatment period, growth and biomass traits, photosynthetic pigments, oxidative stress markers, antioxidant compounds, and proline content were evaluated.
Results
Significant effects (p < 0.05) were observed for genotype, water treatments and their interaction in most of the traits analyzed. The eight MAGIC population parental genotypes displayed a wide variation in their responses to water stress, with some of them exhibiting enhanced root development and reduced foliar biomass. The commercial hybrid had greater aerial growth compared to root growth. The four F1 hybrids among MAGIC parents differed in their performance, with some having significant positive or negative heterosis in several traits. The subset of five MAGIC lines displayed a wide diversity in their response to water stress.
Conclusion
The results show that a large diversity for tolerance to drought is available among the eggplant MAGIC materials, which can contribute to developing drought-tolerant eggplant cultivars.
... Climate changes further affect our ability to farm. Among the types of climate changes, increases in temperature have the most negative impact on crops, including vegetable crops [43][44][45].

The total land used for land-based food farms is less than 1% in Singapore. As a result, more than 90% of Singapore’s food needs are imported. To strengthen food security, Singapore has set a target to develop the capability and capacity of the agri-food industry to locally produce 30% of its nutritional needs by 2030. To achieve this goal, technology is the key to helping farms to “grow more with less”. This review first discusses how aeroponic systems have been adapted for growing all kinds of leafy vegetables in the tropics through the manipulation of root-zone temperature and heat priming to save power energy. Growing vegetable crops indoors and in greenhouses not only allows the growers to achieve high productivity but also enables them to enhance nutritional values. The second part of this paper emphasizes how to achieve substantial yield through deficit irrigation with higher nutritional quality in a cost-effective manner. Growing crops vertically has become increasingly popular, as it increases land use. We establish a commercially viable LED-integrated aeroponic system to grow vegetables vertically. The last part of the paper discusses the impacts of LED spectral quality, quantity, and duration on vegetable production.
Climate change and its impact on agricultural production due to the occurrence of extreme weather events appear to be more imminent and severe than ever, presenting a global challenge that necessitates collective efforts to mitigate its effects.There have been many practical and modelling studies so far to estimate the extent of climate change and possible damages on agricultural production, suggesting that water availability may decrease by 50% and agricultural productivity between 10 and 30% in the coming years ahead. Though there have been many studies to estimate the possible level of damage by the climate change on the production of many agricultural crops, no study has been conducted on the greenhouse tomato production. Therefore, this study was conducted to discover the effects of extreme high temperatures during the 2022–2023 growing season on the high-tech Turkish tomato greenhouse industry through a survey. The results showed that all greenhouses lost yield, ranging from 6 to 53%, with an average of 12.5%. Survey data revealed that irrigation and fog system water consumption increased by 29.32% and 31.42%, respectively, while fertilizer and electricity consumption rose by 23.66% and 19%. Some 76.5% of the growers declared difficulty in climate control, 11.7% reported tomato cluster losses with no information on yield loss, 9% experienced yield losses despite no cluster losses, and 61.7% observed a decline in tomato quality, leading to reduced sales prices. Considering these findings, it is recommended that greenhouses must adopt advanced climate control technologies, expand fog system capacities, and integrate renewable energy sources to enhance resilience against climate-induced challenges. Additionally, improving water-use efficiency, optimizing cooling strategies, using new and climate-resistant varieties and adjusting cropping seasons could help mitigate yield losses due to extreme temperatures. The study results offer extremely valuable insights into greenhouse production for researchers, technology developers, and policymakers for the mitigation of climate change effects and the development of more sustainable production systems.
