Fungal communities in the rhizosphere are crucial in maintaining soil health, driving nutrient cycling, and enhancing plant productivity. This study examined the role of intercropping of oats (Avena sativa L.) with vetch (Vicia sativa L.) and their subsequent use as green manure (incorporating fresh plant biomass into soil to enhance nutrient cycling and microbial activity) on fungal diversity and community structure. Three field treatments were organized as follows: (i) unplanted control, (ii) single-oat cultivation, and (iii) oat–vetch intercropping. In the ripening stage of oats development, the plants in the intercropping treatment were ploughed at a depth of 30 cm as green manure. Soil samples at ripening stage and 3 months after ploughing were analyzed. High-throughput sequencing of the ITS2 region, combined with multivariate diversity analyses (alpha and beta diversity, PCA, NMDS, and UniFrac), revealed distinct fungal community profiles across treatments. Ascomycota dominated under conventional and untreated conditions, while Basidiomycota, Mortierellomycota, and Glomeromycota were enriched in intercropped and organically amended plots, notably at intercropping. Intercropping and green manuring significantly increased species richness, evenness, and phylogenetic fungal diversity. These treatments also supported higher abundances of beneficial fungi such as Mortierella, Glomus, and Trichoderma, while reducing potentially pathogenic taxa like Fusarium. Rank–abundance curves and rarefaction analysis confirmed that diversified systems hosted more balanced and complex fungal assemblages. Beta diversity metrics and ordination analyses indicated strong dissimilarities between the conventionally managed and diversified systems. The results showed that intercropping and organic inputs alter fungal community composition and promote microbial resilience and ecological functionality in the rhizosphere. These practices promoted the development of stable and diverse fungal networks essential for sustainable soil management and crop production. Full article

Peach palm (Bactris gasipaes) is an underutilized Amazonian crop with emerging relevance for plant-based food systems. Global demand for plant-based products continues to expand, reaching USD 28.38 billion in 2024, yet current formulations rely on a narrow set of ingredients with limitations in nutritional quality, functionality, sustainability, and supply-chain resilience. This review synthesizes quantitative evidence on the nutritional composition (carbohydrates 30–72% dm, protein 2–8% dm, lipids 2–14% dm), fatty acid profile, mineral density, and bioactive compounds (carotenoids up to 800 µg/g dm; phenolics 60–90 mg GAE/100 g dm) of peach palm fruit. Techno-functional properties relevant for plant-based applications, such as emulsification, water-binding, and structural contributions in bakery products and meat analogues, are critically examined, along with the effects of processing on nutrient retention and antinutrient reduction. The review also evaluates sustainability attributes and identifies key limitations, including regional cultivation, sensory constraints, and economic and technological barriers. By integrating nutritional, technological, and ecological perspectives, this work highlights the potential of peach palm as a diversified ingredient source and outlines research gaps necessary for future industrial adoption.

Agricultural diversification represents an important strategy for promoting sustainability and resilience in rural regions. Goji berries (Lycium barbarum) have emerged as a promising alternative crop due to their high nutritional and functional potential. In this sense, the search for new crops to diversify the production in southwestern Spain is of main interest for farmers to adapt their productions to consumers claims and to climate change, having alternatives to the classical crops (olives, grapes for wine, etc.). This study evaluated several quality related parameters of three goji berry varieties cultivated in the southwest of Spain. Texture profile analysis (TPA) and puncture tests revealed varietal differences in firmness, cohesiveness, and springiness, influenced by genotype and harvesting time. Other morphological and quality parameters such as moisture, total soluble solids, titratable acidity and color were also affected. Significant differences in antioxidant capacity (ABTS and DPPH assays) were found among the varieties and harvesting times, with NQ7 exhibiting the highest values. Phenolic compounds were identified and quantified by LC–HRMS/MS, detecting 33 compounds, with most belonging to the hydroxycinnamic acids, flavonols and flavanones families. NQ7 presented the highest total phenolic content (74.787 mg/100 g DW), with rutin, coumaric acid derivatives, and naringenin as major contributors. The correlation analysis confirmed a strong relationship between total phenolic content and antioxidant capacity. Overall, the results indicated that goji berries grown in southwestern Spain exhibited favorable quality and bioactive profiles, supporting their suitability for sustainable production and commercialization, including further applications as functional food ingredients.

In the Mediterranean basin, olive cultivation occupies the largest share of agricultural land, due to the region’s favorable soil and climatic conditions. However, the intensification of farming systems has had negative environmental impacts, for which diversified approaches such as agroforestry offer a potential solution. The objective of the present study was to determine the growth of barley, triticale, and pea as cover crops, as well as the respective intercrops in olive orchards and their productivity. The results showed that the intercropping of pea with barley and triticale had the highest yields in dry biomass compared to the other treatments, while barley monoculture recorded the highest yield in terms of grain. The findings demonstrated that intercropping enhances resource-use efficiency, particularly in terms of land productivity, Radiation-Use Efficiency, and Water-Use Efficiency. However, competitive dynamics varied significantly between species and across years, with pea often exhibiting dominance in biomass production, while cereals showed trade-offs in seed yield components due to shading and interspecific competition. These findings can be used for sustainable intensification strategies, ensuring higher productivity while minimizing external inputs in climate-vulnerable regions. Full article

Utilizing more bioresources exposes supply chains to agricultural risks. Therefore, sustainable agricultural practices are crucial for supporting a resilient transition. This requires tools for assessing the environmental performance of cropping systems. However, most existing tools are not adapted to the operational realities of, for example, cosmetics supply chains. The Field Cultivation Index (FCI) has been developed with a threefold aim: 1. assess cropping systems’ strengths and weaknesses and guide their improvement; 2. compare cropping systems to identify the most environmentally friendly; 3. promote initiatives and efforts made to improve sustainability. It also meets the requirements for tackling the specific operational challenges of global industries like cosmetics: it is (i) simple (data collection is easy and straightforward), (ii) deployable in all regions of the world (with a diversity of soils, climates, etc.), and (iii) adaptable to all cropping systems (industrial, family, etc.) and all plant species (perennials, annuals, etc.). Its methodology is based on scientifically recognized evaluation methods and economic operator initiatives. It is built around a theoretical framework embodying the concepts of regenerative agriculture, enabling the qualitative assessment of the impact of cropping systems on five main regenerative environmental outcomes: soil quality improvement water resource conservation biodiversity enhancement, pesticide reduction, and carbon emission mitigation. This article describes the FCI methodology and reveals initial results from the evaluation of about 40 diversified cropping systems. It demonstrates that the FCI is an operational, sensitive, and educational tool capable of determining the performance level of diversified cropping systems, while highlighting the need for a high level of regenerative practice deployment to achieve satisfactory scores. The tool supports farmers and supply chains in assessing and improving the environmental profile of agricultural production systems in line with sustainability goals. Finally, this paper discusses the benefits, limitations, and potential uses of this tool for monitoring the environmental impact of cropping systems within cosmetics supply chains. Full article

Rice is one of the most important staple foods worldwide. Asia, particularly South and Southeast Asia, is a major rice producer, and rice production is also gradually increasing in Africa. However, rice cultivation poses economic and environmental challenges, which are exacerbated by climate change. Hence, diversification of rice-based production systems is highly imperative to improve soil health and thus sustain productivity while also enhancing income opportunities. Vegetables and pulses are crucial components for diversifying rice-based production systems as they have the potential to increase income and improve soil health. The World Vegetable Center has introduced mungbeans and vegetable soybeans to diversify the cereal-based production systems in Asia. About 27–93% of the mungbean area in India, Pakistan, Bangladesh, and Myanmar is planted with varieties containing improved germplasm developed by WorldVeg in collaboration with national agricultural research systems. Additionally, the introduction of vegetables and legumes is highly remunerative and improves dietary diversity, leading to better nutrition. For instance, the productivity of vegetable crops increased by 200–350% when they were combined with improved production practices. Such diversification also holds great promise for improving income and nutrition in Africa. It also enhances the resilience of farming systems, particularly in a changing climate. Hence, governments should prioritize system diversification to enhance the income and livelihood opportunities for smallholders in Asia and Africa. Full article

The condition for the formation of fruit on fruit plants is the presence of flower buds, flowering and proper pollination/fertilisation of flowers. Fruit trees and shrubs are perennial plants, and the processes of flower bud formation and flowering are distant in time. The formation of flower buds occurs in the year preceding flowering and fruiting. The number and quality of flowers are the basic factors that determine the potential yield of fruit trees. Therefore, the review focuses on a thorough review of the latest research on the various stages in the development of trees, in which the processes that determine their flowering take place. The greatest emphasis was placed on the influence of factors that determine the yield of trees after the juvenile stage. Climate change leading to global warming will undoubtedly affect the formation of flower buds, which determine the size of crops. To avoid the unforeseen effects of abiotic factors on the availability of raw materials, such as fruits, it is good to diversify the structure of cultivated plants. Most fruit plants come from the Rosaceae family, so they have many pathogens and pests in common. To increase crop, economic, and habitat biodiversity, it is necessary to look for other, more genetically distant, sometimes even less known fruit-bearing species. Full article

The abandonment of farmland in Europe is a significant issue due to its environmental, socio-economic, and landscape consequences. This tendency mainly impacts marginal and inner areas, located far from large urban districts, because of biophysical and/or socio-economic factors. Although European and national regulations try to turn the fragility of these territories into an opportunity for sustainable development, many of these areas, especially in southern Europe, continue to suffer socio-economic disparities. For this reason, it is necessary to consider regional and district-wide initiatives that can economically revitalize marginal areas while safeguarding their natural capital. Alternative cropping systems, capable of optimizing the quality of some food crops, can play an essential role in the economic development of populations living in marginal areas. These areas, represented by inland zones often abandoned due to the difficulty of applying mechanized agriculture, can represent an opportunity to rediscover sustainable and profitable practices. Among the high-value crops, saffron (Crocus sativus L.), “red gold” and “king of spices”, stands out for its potential. Indeed, thanks to the use of tuff tubs, a more eco-sustainable choice compared to the plastic pots already mentioned in the literature, it is possible to improve the quality of this spice. Furthermore, Crocus sativus L. not only lends itself to multiple uses but also represents a valid opportunity to supplement agricultural income. This is made possible by its high profitability and beneficial properties for human health, offering a way to diversify agricultural production with positive economic and social impacts. It is known that the saffron market in Italy suffers from competition from developing countries (Iran, Morocco, India) capable of producing saffron at lower costs than European countries, thanks to the lower cost of labor. Therefore, this study seeks to identify marginal areas that can be recovered and valorized through an eco-sustainable cultivation system with the potential to enhance the quality of this spice, making it unique and resilient to competition. Specifically, this paper is organized on a dual scale of investigation: (a) at the local level to demonstrate the economic-ecological feasibility of saffron cultivation through the adoption of an alternative farming technique on an experimental site located in Tricarico (Basilicata—Southern Italy, 40°37′ N, 16°09′ E; 472 m. a.s.l.) that, although fertile, is not suitable for mechanized cropping systems; (b) at the regional level through a spatially explicit land suitability analysis to indicate the possible location where to export saffron cultivation. The final map, obtained by combining geo-environmental variables, can be considered a precious tool to support policymakers and farmers to foster a broad agricultural strategy founded on new crop management systems. The adoption of this alternative agroecological system could optimize the use of land resources in the perspective of increasing crop productivity and profitability in marginal agricultural areas.

Faced with the dual challenge of increasing agricultural production (both intensified and diversified) and improving soil health, this study investigated the capacity of legume-based integrated farming systems to restore soil health in the Brazilian Cerrado. For that, we evaluated two experiments in the Minas Gerais State comparing the following land use systems: native vegetation (NV), conventional tillage with Zea mays (CT-8), two pasture systems with Urochloa decumbens (PAST-13) and Urochloa brizantha (PAST-1), and three integrated production systems arranged with Cratylia argentea + Zea mays (IPS-8A), Gliricidia sepium + Zea mays (IPS-8B) and Cratylia argentea + Urochloa brizantha (IPS-1). To assess seasonal variations in microbial attributes (microbial carbon [Cmic], microbial quotient (qMIC), and enzymatic activity, we collected soil samples during the rainy season (December 2021) and the dry season (July 2022). Soil carbon (C) and nitrogen (N) stocks were also evaluated. The soil C and N stocks in pasture systems were similar to VN, with values of 120 and 8.2 Mg ha⁻¹ in PAST-1 at 0–30 cm. Additionally, integrated systems with legume crops promoted an increase in soil C stocks up to 24% (IPS-8B) when compared to monoculture cultivated under conventional tillage (CT-8). We also found that the legume-based integrated farming systems increased Cmic and β-glucosidase activity at the surface layers. Our findings demonstrate that integrated systems utilizing Cratylia argentea and Gliricidia sepium offer a promising approach to soil health restoration and a potential replacement for annual crop and pasture monocultures in the Brazilian Cerrado.

Facility agriculture is essential for diversifying food supply and advancing agricultural modernization. Guided by the concept of new quality productive forces, this study establishes a comprehensive framework to analyze the optimization of facility agricultural land allocation in Zhejiang Province. The findings indicate a relatively low overall allocation level, with higher intensity in the breeding industry compared to crop cultivation. Facility agricultural land is predominantly located in areas with lower elevations, gentler slopes, proximity to roads and rivers, and moderate distances from urban centers. Service areas vary significantly, with grain cultivation having the largest impact, followed by other crop cultivation, fruit and vegetable cultivation, aquaculture, other livestock breeding, and pig farming. As agriculture transitions from small-scale to large-scale and facility-based production, service areas exhibit an inverted U-shaped trend, initially increasing before declining. To optimize decision-making, this study proposes a classification system (shared, modern, safeguard), an entry list (encouraged, restricted, prohibited), and strategies for spatial layout, flexible control, and intensive land use. Guided by green and high-quality development goals, this research establishes a contemporary standard system and optimization strategies, offering scientific and practical guidance for sustainable facility agricultural land development and supporting land resource allocation and industry upgrading.

The decrease in grain plantation areas poses a growing concern for global food security. China, with its large population, increasingly diversified food demands, and relatively small cultivated lands, has suffered deeply from this phenomenon (non-grain production, NGP) in recent years. Since 2020, the central government of China has claimed to deal with this problem by attracting agriculturalists and organizations involved in grain plantation. In this context, understanding the global NGP of the national situation is vital for policy making. Remote sensing is regarded as the most effective and accurate method for this purpose, but existing studies have mainly focused on algorithms operating at the local scale or exploring grain-producing capability from the perspective of agricultural space. As such, the characterization of NGP on a national scale remains deficient. In this study, we tried to bridge the gap through spatio-analysis with a newly published nationwide crop pattern and land use geo-datasets; the quantitative, spatial, and structural features, as well as the utilization of NGP cropland in the year 2019, were observed. The results showed that about 60% of the cropland was used for non-grain plantation. About 15% of the NGP parcels were cultivated with grains at least three times in the past 4 years, and of these 60% and 40% were parcels with double- or single-season plantation, respectively, which could result in a 16–22% increase in the grain-sown area compared with 2019. Forest and grassland were the dominant non-cropping categories which NGP cropland transferred into, indicating more time and economic cost for regaining grains. NGP parcels also presented spatio-heterogeneity regarding cropping intensity and transformation. Parcels with double-season plantation mostly emerged in northern, central, and southern provinces, while those with single-season plantation were always located in northeastern and western provinces. The parcels that were transferred into forest or grassland mainly appeared in southern and Inner Mongolia, respectively, while the parcels in northern and central areas mostly continued cropping. According to these results, we propose remediation policies focusing on raising the cropping intensity of cultivated land in central and northern provinces due to their advantages of water, heat, terrain, and land use change features. Future work is warranted based on this study’s deficiencies and uncertainties. As a forerunner, this study provides a holistic observation of the NGP phenomenon in mainland China on a national scale, and the findings can inform improvements in land use policies concerning grain production and food security in China.

Eryngium foetidum is a promising crop for diversifying agriculture and supporting sustainable development through nutrient-rich unconventional foods. However, limited knowledge about its seed viability and post-harvest management hinders its commercial scalability. This study explored the effects of post-harvest resting treatments on seed quality and vigor, assessing seeds from whole plants, aerial parts, floral spikes, and umbels after 7 and 14 days of resting. Key metrics included seed yield, purity, moisture content, germination, and vigor were assessed. Results showed that seeds retained on whole plants achieved the highest physical purity (72.2%). Seeds that rested for 7 days exhibited higher germination rates (59%), faster germination (mean germination time of 17 days), and improved seedling establishment (70% emergence) compared to seeds that rested for longer durations. These outcomes highlight the importance of specific post-harvest conditions for optimizing assimilate redistribution enhancing seed quality and seedling performance. This research bridges a critical gap in post-harvest management knowledge for E. foetidum, offering practical insights to improve cultivation practices and promote its adoption as a strategic crop. The findings align with global efforts to advance sustainable and innovative agroecosystems. Further studies under diverse environmental conditions and harvest times are recommended to validate these results and support large-scale implementation. Full article

Intensive annual forage cultivation via diversified sowing can increase resource-use efficiency and meet the food requirements of the growing population. However, increasing cultivation time could increase energy demands and production costs with accompanying environmental hazards, such as greenhouse gas (GHG) emissions. A 2-year field experiment including three cropping systems (forage oat monoculture [O], forage oat–common vetch mixed-cropping [O/V], and common vetch monoculture [V]) and two sowing dates (spring and summer) was conducted to comprehensively assess productivity performance, energy utilization, and ecological efficiency under a cereal–legume mixed system over two sowing seasons in Northwestern China. The average system dry matter yield and economic benefit in the mixed system increased by 70.9% and 132.6%, respectively, compared to those of the monoculture system. The application of a mixed-cropping system increased energy efficiency and the ecoefficiency index (EEI) by 61.4% and 132.3%, respectively, with a decline in GHG emission intensity (GHGI) by 49.9%. Spring sowing increased average forage productivity and economic benefit by 9.3% and 18.6%, respectively, with a 23.0% decline in GHGI compared with that engendered by summer sowing. However, there was no correlation between the mixed-cropping system and single sowing date, and the average dry matter yield, economic benefit, and GHGI of the mixed-cropping system were 7.8 t ha⁻¹, 1478.4 USD ha⁻¹, and 0.3 kg CO₂e kg⁻¹, respectively. Furthermore, compared with the monoculture system, the combination of spring and summer seasons under the mixed-cropping system could increase the average annual system forage productivity, economic benefit, and EEI by 37.0%, 49.9%, and 53.1%, respectively, while reducing GHGI by 48.4%. This study demonstrates that the mixed forage oat and common vetch during spring and summer was the sustainable cropping system that achieved high system productivity, good economic returns, high energy utilization, and low environmental risk in Northwestern China.

Crop diversification is pivotal in sustainable agriculture, influencing soil microbial communities and soil nutrient cycling functions. Yet, the impacts of incorporating medicinal plants into crop diversification strategies on the functional characteristics of these microbial communities remain understudied. This research elucidates the benefits of diversified cropping systems by assessing soil nutrient content, diversity and composition of soil microorganisms, the abundance of functional genes involved in carbon (C), nitrogen (N) and phosphorus (P) cycling, and overall agricultural productivity; collectively referred to as ecological benefits. The experimental design included four treatment groups: (1) continuous maize (Zea mays L.) cultivation (MC); (2) maize–A. lancea (Atractylodes lancea Thunb.) intercropping (MA); (3) maize–sorghum (Sorghum bicolor L.) rotation (MS); and (4) maize–A. lancea intercropping combined with sorghum rotation (MSA). Findings indicate that diversified cropping treatments significantly enhance the alpha diversity of soil bacterial communities over fungal communities. NH₄⁺ and NO₃⁻ predominantly influence the composition of soil bacterial communities, with a notable increase in the relative abundance of Acidobacteriota, Gemmatimonadota, and Chloroflexi. Compared to MC treatment, the MA and MSA treatments significantly increased the abundance of C (121.44%, 294.26%), N (206.57%, 294.26%), and P (112.02%, 225.84%) cycling genes. The inverse variance weighting evaluation demonstrates that, compared to the MC treatment, the MS (5.34) and MSA (8.15) treatments significantly boost soil ecological benefits. Overall, diversifying the cultivation of A. lancea with grains can enhance the ecological benefits of the soil. This study offers new perspectives on diversified planting, particularly in terms of species selection and practical combinations on farmland. Full article

The use of conventional farming methods, excessive reliance on fertilizers and inputs, and abrupt shifts in climate have raised significant concerns regarding global agricultural production, particularly in developing countries like Nepal. Agriculture products such as rice hold significant importance in Nepal’s agriculture and economy, serving as a staple food and a crucial source of livelihood for its population. Sustainable cultivation and enhancing productivity are imperative for ensuring food security and economic stability in the country. Adoption of climate-smart agriculture (CSA) practices can minimize detrimental effects, promote sustainability, and enhance resilience towards climate change. We surveyed 200 farmers across four municipalities in the Chitwan District of Nepal to explore the prevalence and socio-economic drivers of the adoption of CSA practices, which include stress-tolerant varieties, efficient water management, and diversified cropping, among others. The results revealed that the adoption of pest-resistant plant varieties was a common CSA practice in the study area. Logistic regression results revealed that the adoption of CSA practices increases with an increase in the education of farmers and membership of climate-related organizations. Similarly, the adoption of CSA practices is negatively associated with an increase in farm size, farmers’ farming experience, and their access to credit facilities. Short-term courses and training could be initiated as a complement to formal education to maximize the adoption of CSA practices. Similarly, climate and farmer-related organizations should be further strengthened to maximize their capacity to facilitate more farmers and provide need-based, timely information flow. This study highlights the potential of CSA to promote sustainability and enhance resilience to climate change, but also identifies barriers such as credit access and the need for tailored policy interventions. Our findings contribute to understanding the dynamics of CSA adoption in vulnerable agricultural settings and can guide future strategies to promote sustainability and climate resilience in smallholder farming communities in developing countries.
