A cationic AIE luminutesogen TBPD2+-6C as a potential bacterial detection agent and bactericide for plants bacterium

The rise of plant bacterial pathogens poses a significant threat to the yield and quality of essential food crops and cash crops globally. Our research introduced a versatile cationic AIE fluorescent probe for detecting and eliminutesating plant bacteria. With its unique aggregation-induced emission property, TBPD2+-6C can effectively detect plant bacteria by causing a fluorescence quenching effect and enables bacterial imaging under green fluorescence channels. Additionally, TBPD2+-6C demonstrates outstanding antibacterial effectiveness, with EC50 values of 0.27, 3.86, 0.47, and 11.5 μg/mL against Xanthomonas oryzae pv. oryzicola (Xoc), X. oryzae pv. oryzae (Xoo), Pseudomonas syringae pv. actinidiae (Psa), and X. axonopodis pv. citri (Xac), respectively. In vivo testing against Xoc revealed TBPD2+-6C showed better activity than commercial thiodiazole copper (TC) and bismerthiazol (BT). Furthermore, the investigation into the antibacterial mechanism revealed that the cationic compound can effectively integrate into the bacterial membrane, disrupt the membrane structure, trigger ROS accumulation, and inhibit biofilm formation. In conclusion, the development of multifunctional, broad-spectrum antimicrobial system molecular designs for rapid real-time detection, imaging, and elimination of resistant microbes could play a vital role in combating pathogens.

Continuous cropping obstacles: Insights from the community composition and the imbalance carbon fluxes within soil nematode food web

Long-term continuouscroppingcan lead to the deterioration of soil environment and the decrease of soil productivity. However, the biological mechanism on the negative effects of long-term continuous cropping has not been extensively explored. Soil nematode food web with multiple trophic levels play critical roles in nutrient cycling and energy flowing in the agroecosystem. Quantifying the carbon flux through different trophic channels within the nematode food web can indicate how continuous cropping influences carbon cycling in the agroecosystem by altering soil biota communities. Therefore, the effects of continuous peanut cropping with different years (1, 5, 20, and 30 years) on soil properties, soil nematode community composition, carbon flux within nematode food web and crop yields were investigated. Results showed that soil pH significantly decreased with increasing continuous cropping years. Differently, soil organic carbon and total nitrogen were the highest in 20-year, and decreased in 30-year of continuous cropping. As continuous cropping years increased, the relative abundance of microbivorous nematodes decreased and that of plant parasites reached as high as 76.11 % and 68.22 % in 20- and 30-year, respectively. Pearson correlation analysis revealed the nematode diversity, the carbon flux uniformity and peanut yield had a significant negative correlation with continuous cropping years. The random forest model indicated that the soil pH and the relative abundance of plant parasites were the key influence factor of the carbon flux uniformity within soil nematode food web. Outbreaks of plant parasites lead to the disruption of carbon flux uniformity within soil nematode food web, which can increase the risk of peanut yield decline after long-term continuous cropping. In conclusion, continuous peanut cropping changed soil properties, reduced soil nematode diversity, and disturbed the multitrophic carbon flux complementarity and uniformity in soil nematode food web, ultimately limiting the crop productivity. This study enhances our understanding of the importance of the resource transfers among soil food web in maintaining sustainable agroecosystem productivity.

Warming-induced soil moisture stress threatens food security in India.

Soil moisture (SM) interconnects various components of the Earth system and drives the land-atmosphere feedbacks and food production. However, around 40% of global vegetated land experiences SM drying. India is one of the global hotspots of land-atmosphere interactions and an extensively agrarian economy, but underexplored in terms of SM dynamics and its ramifications on food security. Here, we examine the mechanism of SM drying and its implications on cropland productivity in India based on remote sensing measurements and land surface model simulations in recent decades (2000-2019) and future projection of the 21st century. We find SM reduction predominantly in monsoon (4.5%) and winter (3%) seasons that areinthemajor agricultural seasonsofKharif and Rabi, respectively. Machine learning (ML)-based random forest (RF) reveals that temperature (T, 30.76%) is the dominant driver of SM variability, and then precipitation (P, 26.34%), evapotranspiration (ET, 26.08%) and surface greenness (16.82%). Concurrently, India experiences severe warming in terms of land (0.59 ℃/dec), soil (0.48 ℃/dec) and soil heat flux (SHF, 0.16 W/m2/dec) during 2000-2019. Partial correlation analysis between SM and T limiting the influence of P reveals a strong negative (> - 0.5) relationship in the agriculture intensive regions of Indo-Gangetic Plain (IGP) and South India (SI). Drying owing to warming and increased SHF, termed as warming-induced moisture stress, reduces gross primary productivity (GPP) (i.e. browning) and yield of major food crops of wheat, rain-fed rice, maize and soyabean, predominantly in SI and eastern IGP. Granger Causality shows that warming-induced soil moisture stress has a maximum temporal lag of 1month. In a warming world, the ever-growing population demands more food, and therefore, the warming-induced soil moisture stress is a serious threat to food security in India and similar agro-climatic regions of the world. This calls for climate-resilient agriculture, better agronomic management, improved irrigation and adoption of water-efficient crops.

Cocoa vs. food crops: smallholder’s seasonal food access and extension support for climate adaptation in Ghana

ABSTRACT The food security implications of the production of cocoa compared to food crops and the phenomenon of the lean season amongst smallholder farmers have been well-researched. Yet, the literature has yet to consider how climate variability affects these dynamics. This study addresses this gap by comparing the contributions of cocoa and food crops to food stability and access during extreme and erratic weather events. It then compares government extension support for households’ climate adaptation of these crops. Our data draw on the case of smallholder cocoa farmers in Ghana’s Central Region and comprise a survey of 250 households, 16 focus group discussions, and 81 semi-structured interviews with smallholders, market sellers, and government officials. We find that food crops are essential for households’ food access during the cocoa lean season and when cocoa yields are reduced by climate change-related extreme or erratic weather events. However, food crop yields are themselves negatively affected by climate variability impacts. Furthermore, many farmers lack climate adaptation strategies or support for food crops as government extension services focus instead on export-driven cocoa. We argue that to promote households’ food stability, more smallholder extension support for food crop production and climate adaptation is urgently needed.

Exploring Endophytic Fungi as Natural Antagonists against Fungal Pathogens of Food Crops.

The yield and quality of cultivated food crops are frequently compromised by the prevalent threat from fungal pathogens that can cause widespread damage in both the pre-harvest and post-harvest stages. This paper investigates the challenges posed by fungal pathogens to the sustainability and yield of essential food crops, leading to significant economic and food security repercussions. The paper critiques the long-standing reliance on synthetic fungicides, emphasizing the environmental and health concerns arising from their widespread and occasionally inappropriate use. In response, the paper explores the potential of biological control agents, specifically endophytic fungi in advancing sustainable agricultural practices. Through their diverse symbiotic relationships with host plants, these fungi exhibit strong antagonistic capabilities against phytopathogenic fungi by producing various bioactive compounds and promoting plant growth. The review elaborates on the direct and indirect mechanisms of endophytic antagonism, such as antibiosis, mycoparasitism, induction of host resistance, and competition for resources, which collectively contribute to inhibiting pathogenic fungal growth. This paper consolidates the crucial role of endophytic fungi, i.e., Acremonium, Alternaria, Arthrinium, Aspergillus, Botryosphaeria, Chaetomium, Cladosporium, Cevidencealdinia, Epicoccum, Fusarium, Gliocladium, Muscodor, Nigrospora, Paecilomyces, Penicillium, Phomopsis, Pichia, Pochonia, Pythium, Ramichloridium, Rosellinia, Talaromyces, Trichoderma, Verticillium, Wickerhamomyces, and Xylaria, in biological control, supported by the evidence drawn from more than 200 research publications. The paper pays particular attention to Muscodor, Penicillium, and Trichoderma as prominent antagonists. It also emphasizes the need for future genetic-level research to enhance the application of endophytes in biocontrol strategies aiming to highlight the importance of endophytic fungi in facilitating the transition towards more sustainable and environmentally friendly agricultural systems.

Revolutionizing Rice: The Synthesis of Nature's Evolution and Biotechnology in C4 Rice

Agriculture plays a fundamental role in meeting the essential needs of humanity, yet numerous factors continuously influence agricultural production and productivity. Over time, evolving agricultural practices have significantly increased yields of staple food crops, thereby enhancing global food security. However, as the world's population continues to grow, there is a pressing need to further augment crop yields. Historically, increases in yield were achieved by expanding cultivated land, but rapid industrialization and urbanization have diminished available agricultural land and depleted natural resources essential for farming. In response to these challenges, enhancing crop photosynthetic efficiency has emerged as a pivotal strategy. Photosynthesis, the process by which plants convert sunlight into energy, has been optimized in various crops through evolutionary and biotechnological approaches. One such innovation is the adaptation of the C4 photosynthetic pathway into C3 rice, a staple food for billions worldwide. The C4 pathway, found in several efficient crops like maize and sugarcane, enhances carbon dioxide uptake and reduces photorespiration, leading to improved water and nitrogen use efficiency. This review explores the integration of nature’s evolutionary principles with cutting-edge biotechnological advancements in the development of C4 rice. By introducing the C4 pathway into rice—a traditionally C3 plant—scientists aim to dramatically increase its productivity and resilience to environmental stressors. This transformative approach not only holds promise for meeting future food demands sustainably but also addresses the challenges posed by climate change and resource scarcity. Moreover, the review examines the scientific basis, technological innovations, and potential agricultural implications of implementing C4 rice. It highlights the collaborative efforts of researchers, agronomists, and biotechnologists worldwide in reimagining rice cultivation to secure global food supplies while minimizing environmental impact. Ultimately, the integration of C4 photosynthesis into rice represents a significant step forward in agricultural innovation, poised to redefine food production capabilities and enhance global food security in the face of escalating population growth and environmental change.

Perceived Effects of Climate Variability on Crop Production in Imo State, Nigeria

This study assessed the effect of climate variability on crop production in Imo State, Nigeria. Climate variability has direct impacts that cause vulnerability to the natural and social systems through changes in average temperatures, temperature extremes and extreme weather events like flooding and droughts. The study described the socio-economic characteristics of the crop farmers, ascertained crop farmers’ knowledge on climate variability, determined the perception of farmers on climate variability, and examined the perceived effects of climate variability on food crop yield production. A multistage sampling procedure was used in the selection of one hundred and eighty-three (183) crop-based farmers. Structured questionnaires were used in obtaining data and the data collected were analyzed using frequency, percentage, mean score and multiple regression analysis. Findings show that the mean age was 48.77 years. Majority (71.58%) were females. Majority (78.14%) were married with an average household size of 8 persons. Most (65.57%) had secondary education with an average farming experience of 21.18 years. Average farm size and farm income were 1.24 hectares and ₦33,000.00 respectively. Findings show that farmers had major knowledge of climate variability as zero/minimum tillage practices (99.45%) and knowledge on rain-water harvesting (97.81%) amongst others. Farmers perceived climate variability (x̄ = 3.49), starts late and ends early (x̄ = 3.45), extremes in temperatures (x̄ = 3.39), too much/heavy rains (x̄ = 3.396) and long dry spells during the season (x̄ = 3.51), amongst others. Crop farmers further perceived that climate variability has resulted in declining crop yields (x̄ = 3.35), increased water scarcity on farm (x̄ = 3.45), high incidences of pest and diseases (x̄ = 3.29), and increased rate of erosion/flooding (x̄ = 3.50) amongst others. The study strongly recommends that the extension services should be strengthened so as to pay farmers regular visits to ascertain their challenges on the effects of climate variability and know where to assist them.

Nanobiosensors based on on-site detection approaches for rapid pesticide sensing in the agricultural arena: A systematic review of the current status and perspectives.

The extensive use of chemical pesticides has significantly boosted agricultural food crop yields. Nevertheless, their excessive and unregulated application has resulted in food contamination and pollution in environmental, aquatic, and agricultural ecosystems. Consequently, the on-site monitoring of pesticide residues in agricultural practices is paramount to safeguard global food and conservational safety. Traditional pesticide detection methods are cumbersome and ill-suited for on-site pesticide finding. The systematic review provides an in-depth analysis of the current status and perspectives of nanobiosensors (NBS) for pesticide detection in the agricultural arena. Furthermore, the study encompasses the fundamental principles of NBS, the various transduction mechanisms employed, and their incorporation into on-site detection platforms. Conversely, the assortment of transduction mechanisms, including optical, electrochemical, and piezoelectric tactics, is deliberated in detail, emphasizing its advantages and limitations in pesticide perception. Incorporating NBS into on-site detection platforms confirms a vital feature of their pertinence. The evaluation reflects the integration of NBS into lab-on-a-chip systems, handheld devices, and wireless sensor networks, permitting real-time monitoring and data-driven decision-making in agronomic settings. The potential for robotics and automation in pesticide detection is also scrutinized, highlighting their role in improving competence and accuracy. Finally, this systematic review provides a complete understanding of the current landscape of NBS for on-site pesticide sensing. Consequently, we anticipate that this review offers valuable insights that could form the foundation for creating innovative NBS applicable in various fields such as materials science, nanoscience, food technology and environmental science.

The effects of climate extreme events on selected food crop yields in Sub-Saharan Africa

The agricultural sector is essential for economic growth. However, agricultural performance can be limited by factors such as climatic risks. This paper aims to analyse the effect of climate extreme events on selected food crop yield in sub-Saharan Africa (SSA). The study uses data from the Food and Agriculture Organisation (FAO) database for maize, rice, and sorghum yields. Also, we used data obtained from the International Disaster Database of the Centre for Research on the Epidemiology of Disasters (CRED) for floods and droughts over the period 1990–2020. The data were analysed based on the Fully Modified Ordinary Least Squares (FMOLS). The results showed that climate extreme events negatively affected maize, rice and sorghum yields. Also, the findings showed that floods and droughts in past years negatively influence current yields of maize, rice and sorghum. Moreover, agricultural labour force, fertilizer and financial development are the main transmission channels through which floods and droughts can affect maize, rice and sorghum yields. The study concludes by recommending that policies aimed at promoting climate change adaptation measures as well as agricultural insurance could make the agriculture sector more resilient to climate extreme events and in turn that could improve agricultural productivity and reduce food insecurity.

Foliar application of commercial humic substances for possible increase of nutrient status and yield of oilseed rape

Inconsistent results on the effects of humic substances (HS) on yield and nutrient status of important food crops, including oilseeds, confirm the need for further research on different HS products to match their use to actual field conditions. The aim of this study was to evaluate the effect of foliar application of commercially produced peat- and vermicompost-derived HS preparations on nutrient status and yield of spring oilseed rape (Brassica napus). The field experiment was carried out in Stende State Cereals Breeding Institute, Latvia, during the vegetation season of 2012, using the spring oilseed rape cultivar ‘Perfect’. Although foliar sprays of HS were applied during the critical stages of crop development from rapid growth to flowering, they were ineffective in improving the supply of the deficient nutrients (N, K, B, Zn, Cu) in leaves. Moreover, both tested HS products caused a decrease in Cu and B content in the seeds, which resulted in a negative trend in oilseed rape seed yield. Therefore, the conducted experiment demonstrated that foliar application of both HS preparations was ineffective to promote nutrient status and did not contribute to spring oilseed rape yield.

Ozone pollution contributes to the yield gap for beans in Uganda, East Africa, and is co-located with other agricultural stresses

Air quality negatively impacts agriculture, reducing the yield of staple food crops. While measured data on African ground-level ozone levels are scarce, experimental studies demonstrate the damaging impact of ozone on crops. Common beans (Phaseolus vulgaris), an ozone-sensitive crop, are widely grown in Uganda. Using modelled ozone flux, agricultural surveys, and a flux-effect relationship, this study estimates yield and production losses due to ozone for Ugandan beans in 2015. Analysis at this scale allows the use of localised data, and results can be presented at a sub-regional level. Soil nutrient stress, drought, flood risk, temperature and deprivation were also mapped to investigate where stresses may coincide. Average bean yield losses due to ozone were 17% and 14% (first and second growing season respectively), equating to 184 thousand tonnes production loss. However, for some sub-regions, losses were up to 27.5% and other crop stresses also coincided in these areas. This methodology could be applied widely, allowing estimates of ozone impact for countries lacking air quality and/or experimental data. As crop productivity is below its potential in many areas of the world, changing agricultural practices to mitigate against losses due to ozone could help to reduce the crop yield gap.

A bibliometric analysis of the literature on crop yield prediction: insights from previous findings and prospects for future research.

This research presents a bibliometric analysis of articles predicting crop yield using machine learning methods. While several systematic review articles exist, a comprehensive bibliometric analysis illustrating the knowledge structure and research trends, along with collaboration networks among authors, institutions, and countries in this field, has not been conducted. The study focused on 826 articles published over a 32-year period (1992 to 2023) and revealed a significant increase in publications, particularly in recent years. Zhang Zhao from China authored the majority of articles, while the highest number of citations was associated with articles by Zhu Yan and Lobell. Leading countries in article publications are the USA, China, India, Germany, Australia, and Canada, showing strong interconnections in citing each other's research. The Chinese Academy of Sciences and the US Department of Agriculture are the institutions with the highest number of articles and citations in this domain. The journals Agricultural and Forest Meteorology and Remote Sensing are recognized as top ranking journals in this field (Q1). Based on co-occurrence analysis, three main thematic domains were identified: weather and crop yield prediction, plant growth simulation models, and crop yield prediction using remote sensing data. The research suggests a focus on variables such as disease, pests, insects, and soil salinity when predicting yield. Additionally, greater attention should be given to discussions on food security and crop yield, especially in developing countries.

Assistance to Farmers in Increasing Rice Production Through Direct Seed Planting System in Langsat Permai Village, Bungaraya District

The increase in agricultural yields of food crops and horticulture in Langsat Permai Village, Bungaraya District was initiated by the construction of canal blocking in the activities of the Partner Village Service Program by DIKTI in the 2017-2019 implementation year which will continue until 2023. However, the harvest index (HI) of rice has not reached 300 due to the transplanting system, so that it takes quite a long time from the transplanting period to finally harvesting and replanting. Therefore, the rice cultivation system with the direct seed planting system can be a solution that can help farmers increase the harvest index (HI) and rice crop production. The activity partners who were the targets of the activity were farmers and members of the Langsat Permai Village youth group. Assistance is carried out by providing knowledge about rice cultivation using the direct seed planting system starting from the understanding of the direct seed planting system, its tool, the advantages and disadvantages of rice cultivation using the direct seed planting system, as well as the stages of the direct seed planting system cultivation from land preparation, seed preparation, planting to fertilization. Based on the results of the mentoring carried out, the knowledge of farmers and youth groups in Langsat Permai Village about rice cultivation using the direct seed planting system has increased compared to before the mentoring activities were carried out.

Productivity and economic feasibility of cultivated forage and food crops in the central highlands of Ethiopia

The study was conducted to evaluate the yield performance of improved forage and food crops and to estimate the profitability of fodder and food crops in Holetta and Ejere areas, central highlands of Ethiopia during 2019 and 2020 cropping seasons. The experiment was laid out in randomized complete block design with three replications and evaluated two annual forage crops, two perennial forage crops, and two cereal food crops. Data on herbage dry matter (DM) yield was collected for forage crops while straw and grain yields were measured for food crops. Partial budget analysis was made to evaluate the economic feasibility of forage and food crops production. The result revealed that the herbage DM yield varied (P<0.05) at each location during each production year and combined over years and between the two locations. The straw and grain yields of food crops also varied (P<0.05) between the two production years and locations. The nutritive values of herbage and straw yields of forage and food crops differed (P<0.05) for all measured parameters. The crude protein and in-vitro dry matter digestibility of perennial forage crops were relatively higher than annual forage crops and straw of food crops. The partial budget analysis result indicated that the gross revenue (GR) and net return (NR) obtained from food crops were the highest followed by annual forage crops while the least was recorded from perennial forage crops during the first year of production. However, perennial forage crops produced the higher GR and NR than food crops and annual forage crops in the second year of production. In the second year of production, among the forage crops, Desho grass generated 308, 293, 287, and 232% while Rhodes grass generated 99, 92, 90, and 62% more NR than wheat, sole oat, barley, and oat/vetch mixtures, respectively. The benefit-cost ratio (BCR) of perennial forage crops was the lowest (3.0 for Desho and 1.6 for Rhodes) in the first year of production but the ratio was the highest (17.2 for Desho and 8.6 for Rhodes) in the second year of production. This confirms the better economic feasibility of perennial forage crops as they can be maintained using minimal management cost once they have been established.

Towards sustainable food crop production: Drivers of shift from crop production to mining activities in Ghana's Arable Lands

This study contributes to the observed reduction of arable lands discourse by examining the shift in land use patterns as well as factors influencing farmers' shift from crop production to mining activities. To achieve this, we employed a combination of Geographic Information System (GIS) technology and Cragg's Double Hurdle Econometric Model as analytical tools. Our approach integrates an econometric model of land use with GIS simulations that predict the spatial pattern of land-use change. The results revealed that crop production lands have been converted into artisanal small-scale mining (galamsey) sites, a development which has implications on food security, life on land and effective utilizations of land and water resources. The results also showed that membership in Farmer-Based Organizations (FBOs), access to credit, and low yield of food crops influenced farmers to shift from crop production to participate in mining activities. In addition, the extent of participation in mining was influenced by family size, membership in FBOs, and low crop yield. While mining operations offer substantial economic benefits, it is crucial to strike a balance between land use for mining activities and food crop production. This is because it has the potential to worsen recent hikes in food prices and subsequently leading to rising inflation rates in Ghana. Our findings have implications on achieving multiple SDGs, viz. SDG 2 (Zero Hunger), SDG 6 (Clean Water and Sanitation) and SDG 15 (Life on Land) as minimizing illegal mining helps increase food production as well as protect water bodies and land. We therefore suggest that government should take steps to make credit accessible to farmers by collaborating with financial institutions and also collaborate with Crops Research Institutes to develop high-yielding crop varieties. Future research could focus on exploring the impact of participating in mining activities on the profitability of food crop production in Ghana.

A perspective study for the assessment of field robots in agriculture: An enhanced fuzzy MADM approach

The industrial revolution led in the creation of robots capable of performing complicated tasks in a range of industries. Robotic agrifarming is an innovative smart farming technology that can improve food safety and crop yield and address the global labour crisis. Agribots are used to undertake field tasks ranging from seeding through harvesting, which improve soil quality and guarantee long-term growth. As a result, the development of a decision-support system for determining the most appropriate robot for an agricultural operation is necessary. This study develops a T2IF-based integrated decision system for evaluating the situation at hand. The performance of five field robots is assessed based on technical, economic, social, political, and environmental aspects using the integrated BWM-MULTIMOORA methodology. The advantage of the developed ranking technique is that it follows Borda’s rule for prioritizing the alternatives rather than dominance theory, where both the utility and the subordinate ranking order of methods are considered. In addition, a comparative and sensitivity investigation is carried out to examine the stability of the results.

Fluorides immobilization through calcium aluminate cement-based backfill: Accessing the detailed leaching characterization under torrential rainfall

Urbanization and economic development have increased the demand for fertilizers to sustain food crop yields. Huge amounts of by-products, especially phosphogypsum (PG), are generated during the wet processing of rock phosphate to produce fertilizers. Chronic exposure to fluoride in phosphogypsum in groundwater as a result of the weathering of fluoride-containing waste poses a significant health risk to millions of people. We propose a method for using calcium aluminate cement (CAC) to remediate high fluoride contents in solid waste. Column leaching tests under harsh rainfall conditions confirmed the efficient fluoride immobilization capacity of a CAC binder. Although the fluoride concentrations in leachates during the first 1–2 days (1.25 mg/L) slightly exceeded the threshold of 1.00 mg/L, the concentrations over 3–28 days (ranging from 0.98 to 0.83 mg/L) consistently remained well within the acceptable range. Furthermore, our characterization and geochemical modeling revealed the fluoride retention mechanisms of CAC-stabilized PG under laboratory-simulated conditions of torrential rainfall. During leaching, physical encapsulation prevents fluoride from contacting leachate. However, an unfavorable pH value can cause the release of fluoride from the cement matrix, which is subsequently captured by aluminate hydrate through adsorption or co-precipitation. We quantified the carbon footprint of CAC for immobilizing 1 mg of fluoride in PG, obtaining a remarkably low value of 4.4 kg of CO2, in contrast to the emissions associated with the use of ordinary Portland cement (OPC). The findings suggest a unique opportunity for extensive PG remediation. This opportunity extends the horizons of achieving zero-waste emissions in the phosphorus industry and has practical significance in the context of reducing carbon emissions.

Intercropping Perennial Fruit Trees and Annual Field Crops with Aromatic and Medicinal Plants (MAPs) in the Mediterranean Basin

The Mediterranean basin (MB), a “climate hotspot”, is experiencing faster than average increases in global temperature and water deficit, as well as soil degradation, with detrimental impacts on food crop yield and pest/pathogen incidence. Hence, there is an urgent requisite for sustainable crop diversification strategies to promote crop resilience, soil quality conservation and pest/pathogen control. Intercropping is a strategy that has yet to be widely adopted. Presently, cereal–legume combinations represent the most common intercrops. Of relevance, a large number of medicinal and aromatic plants (MAPs), native to the MB, serve as potentially profitable indigenous resources for intercropping with food crops. Environmentally sustainable benefits of MB MAP intercropping with food crops have ironically been reported largely from research outside the MB. The present study aims to review the published literature from 2003 to 2023 on MAP intercropping with perennial nut/fruit crops and annual field crops in the MB. Published research is scarce but shows a promising upward trend, with 70% and 47% of intercropping studies with perennials and annual field crops, respectively, dated between 2020 and 2023. MAP intercropping shows potential in augmenting yield, pest/pathogen and weed control, soil health and cash crop quality, warranting further research with more widespread adoption in the MB.
