The European chickpea market raises concerns about health risks for consumers due to contamination by mycotoxins. Contamination levels can vary depending on the farming system, and rapid and reliable screening tools are desirable. In this study, marketed chickpea seed samples from organic and non-organic farming systems were analyzed for fungal and mycotoxin contamination. Aspergillus and Penicillium were the most frequently identified mycotoxigenic genera. Significant differences in fungal detection were observed among the three isolation methods used, whose combined application is proposed to enhance detection efficiency. The number of Aspergillus and Penicillium colonies was significantly higher in the organic samples. Molecular analysis identified different species within each genus, including several not previously reported in chickpea, as well as potentially aflatoxigenic species such as A. flavus/oryzae and A. parasiticus. LC-MS/MS analysis revealed aflatoxin production only by A. parasiticus, which was present in low amounts. However, the presence of potentially aflatoxigenic Aspergillus species suggests that chickpeas should be monitored to detect their safety and subsequently protect consumer health. A qPCR protocol targeting the omt-1 gene, involved in aflatoxin biosynthesis, proved to be a promising rapid tool for detecting potentially aflatoxigenic Aspergillus species. Full article

Biochar is a carbon-rich material produced through the pyrolysis of agricultural waste. It effectively enhances the physical, chemical, and biological properties of salinity-affected soils. Chickpea (Cicer arietinum L.) is the world’s third most important legume crop, currently cultivated in over 50 countries. However, no study has yet established recommended biochar application rates for this crop under saline soil conditions. Therefore, this study aimed to assess the chemical properties of a clay soil following the application of varying rates of biochar and NaCl, and to evaluate their subsequent effects on the growth and yield of Cicer arietinum L. To evaluate the effect of biochar, a completely randomized experimental design with ten replicates was implemented. The biochar was produced from corncobs (Zea mays) and applied at two rates (1.5% and 3%). Soil salinity levels were classified into three groups: non-saline (S1 = 1.2 dS·m⁻¹), low/moderate salinity (S2 = 4.2 dS·m⁻¹), and moderate salinity (S3 = 5.6 dS·m⁻¹). The treatments were placed in pots for 100 days. The results demonstrated that biochar applications at 1.5% and 3% rates improved both soil chemical properties (pH, EC, SAR, and ESP) and the growth of C. arietinum across all evaluated treatments. The 3% biochar treatment showed superior effects compared to the 1.5% application. Therefore, biochar application in C. arietinum production emerges as an effective agronomic strategy to mitigate abiotic stress while simultaneously enhancing crop productivity and sustainability.

The production of food with a naturally enriched protein content is a strategic response to the growing global demand for sustainable protein sources. Wood distillate (WD), a by-product of the pyrolysis of woody biomass, has previously been shown to increase the protein concentration and bioavailability in chickpea seeds. Here, we evaluated the effect of 0.5% (v/v) WD soil drenching on chickpea productivity, nutritional profile, and proteomic pattern. WD treatment significantly improved the yield by increasing plant biomass (+144%), number of pods and seeds (+148% and +147%), and seed size (diameter: +6%; weight: +25%). Nutritional analyses revealed elevated levels of soluble proteins (+15%), starch (+11%), fructose (+135%), and polyphenols (+14%) and a greater antioxidant capacity (25%), alongside a reduction in glucose content, albeit not statistically significant, suggesting an unchanged or even lowered glycemic index. Although their concentration decreased, Ca (−31%), K (−12%), P (−5%), and Zn (−14%) in WD-treated plants remained within normal ranges. To preliminary assess the quality and safety of the protein enrichment, a differential proteomic analysis was performed on coarse flours from individual seeds. Despite the higher protein content, the overall protein profiles of the WD-treated seeds showed limited variation, with only a few storage proteins, identified as legumin and vicilin-like isoforms, being differentially abundant. These findings indicate a general protein concentration increase without a major alteration in the proteoform composition or differential protein synthesis. Overall, WD emerged as a promising and sustainable biostimulant for chickpea cultivation, capable of enhancing both yield and nutritional value, while maintaining the proteomic integrity and, bona fide, food safety.

The Fabaceae family, the third-largest among flowering plants, is nutritionally vital, providing rich sources of protein, dietary fiber, vitamins, and minerals. Leguminous plants, such as soybeans, peas, and chickpeas, typically contain two to three times more protein than cereals like wheat and rice, with low fat content (primarily unsaturated fats) and no cholesterol, making them essential for cardiovascular health and blood sugar management. Since the release of the soybean genome in 2010, genomic research in Fabaceae has advanced dramatically. High-quality reference genomes have been assembled for key species, including soybeans (Glycine max), common beans (Phaseolus vulgaris), chickpeas (Cicer arietinum), and model legumes like Medicago truncatula and Lotus japonicus, leveraging long-read sequencing, single-cell technologies, and improved assembly algorithms. These advancements have enabled telomere-to-telomere (T2T) assemblies, pan-genome constructions, and the identification of structural variants (SVs) and presence/absence variations (PAVs), enriching our understanding of genetic diversity and domestication history. Functional genomic tools, such as CRISPR-Cas9 gene editing, mutagenesis, and high-throughput omics (transcriptomics, metabolomics), have elucidated regulatory networks controlling critical traits like photoperiod sensitivity (e.g., E1 and Tof16 genes in soybeans), seed development (GmSWEET39 for oil/protein transport), nitrogen fixation efficiency, and stress resilience (e.g., Rpp3 for rust resistance). Genome-wide association studies (GWAS) and comparative genomics have further linked genetic variants to agronomic traits, such as pod size in peanuts (PSW1) and flowering time in common beans (COL2). This review synthesizes recent breakthroughs in legume genomics, highlighting the integration of multi-omic approaches to accelerate gene cloning and functional confirmation of the genes cloned.

Chickpeas (Cicer arietinum L.) were popular for their high nutritional profile and abundance of bioactive constituents, making them highly sought after in the consumer market. This investigation evaluated the impact of germination on the levels of total phenolics, total flavonoids, and other bioactive compounds, as well as free amino acids, soluble proteins, dietary fiber, and starch, in two chickpea sprout cultivars. The results demonstrated that germination significantly enhanced the concentrations of total flavonoids and phenolics in chickpeas. Compared to ungerminated seeds, the total flavonoid content in Xinying No. 1 and Xinying No. 2 sprouts increased by 3.95-fold and 3.25-fold, respectively, while total phenolic content increased by 2.47-fold and 2.38-fold. Germination also significantly augmented free amino acid, soluble protein, and total dietary fiber content while reducing resistant starch and insoluble dietary fiber. Concurrently, the bioaccessibility of essential nutrients was substantially improved, as indicated by enhanced solubility. This research provided valuable insights for optimizing the nutritional quality and bioactive compound content of chickpeas through sprouting technology. These results provided critical insights for optimizing the nutritional and functional properties of chickpeas via sprouting and established a scientific basis for the development of functional foods from germinated chickpeas, underscoring their potential to support dietary health and wellness.

This study evaluated the physiological and biochemical responses of chickpea (Cicer arietinum L.) to foliar application of cineole, carvacrol, and thymol at concentrations of 500 and 1000 ppm. Carvacrol at 1000 ppm significantly enhanced fresh biomass (+15.4%) and aerial biomass (+46.2%), whereas thymol significantly reduced plant height (−20.2%) and overall biomass, yet notably increased chlorophyll content (+23.3%) and vitamin C levels (+41.4%) at the same concentration. Cineole significantly improved antioxidant capacity by increasing total phenolic content (+15.5% at 1000 ppm) and total flavonoid content (+19.1% at 500 ppm), but simultaneously decreased soluble protein synthesis and chlorophyll content (−39% at 500 ppm). Mineral analysis showed notable increases in calcium content following treatment with cineole (+30.5% at 1000 ppm) and carvacrol (+32% at 500 ppm), while thymol at 1000 ppm significantly reduced phosphorus, potassium, manganese, iron, copper, and zinc accumulation. Molecular docking and dynamic simulations revealed strong interactions of thymol and carvacrol with essential enzymes, specifically ascorbate peroxidase and phenylalanine ammonia-lyase, which are involved in antioxidant and phenolic metabolism pathways. These molecular interactions suggest potential contributions of thymol and carvacrol to plant stress resilience mechanisms, although further experimental validation is needed to confirm their roles in vivo. These findings emphasize the importance of optimizing monoterpene concentrations, indicating that carefully calibrated treatments could effectively enhance chickpea growth, nutritional quality, and stress tolerance within sustainable agricultural practices.

The moth Helicoverpa armigera (Lepidoptera: Noctuidae), better known as the pod borer, poses significant threats to chickpea (Cicer arietinum L.) production. Therefore, effective and sustainable crop management strategies are required to mitigate the impact of this cosmopolitan pest. The present study aimed at investigating the potential of wood distillate (WD), a liquid byproduct of the pyrolysis of waste lignocellulosic biomass, to both reduce H. armigera pest incidence and to enhance crop yields in field-grown chickpea. The application of WD as a foliar spray effectively reduced the number of damaged pods by 35% during the plant´s reproductive stage compared with water-sprayed plants (~16 vs. 24 bored pods plant⁻¹, respectively) and increased the number of healthy pods (~16 vs. 10 pods plant⁻¹, respectively). Moreover, the lower pest incidence was accompanied by an improvement of both the seed yield and the quality at the plant´s full maturity stage. Specifically, WD-treated plants increased both the number and weight of seeds by ~80% compared to water-sprayed plants (~23 vs. 13 and 5.5 vs. 3 plant⁻¹, respectively) which further showed a remarkable improvement in their nutritional value, with the concentration of total polyphenols, flavonoids, starch, calcium, and magnesium increasing by 17%, 56%, 43%, 23%, and 15%, respectively. These results underscore the potential of WD to both improve chickpea performance and to reduce H. armigera damage to sustainably improve the productivity of this critical legume crop, aligning with the principles of the circular economy and offering an environmentally friendly alternative to synthetic pesticides and fertilizers in agriculture.

The present study investigates the impact of freeze drying on the physical, cooking, and functional properties of some chickpea (Cicer arietinum) cultivars. Freeze drying was applied to reduce the cooking time in addition to evaluating its effect on other quality attributes. The results revealed a significant reduction in cooking time in the freeze-dried chickpeas (67.00–77.33 min) compared to the control chickpeas (80.33–93.66). Additionally, functional properties were enhanced, such as the water absorption capacity, which increased from 0.84–0.98 g/g to 1.051–1.24 g/g, the oil absorption capacity, which increased from 0.73–0.98 g/g to 0.909–980 g/g, and the foaming capacity, which increased from 42.58–45.16% to 44.37–47.20%. The textural analysis revealed that freeze drying resulted in a decrease in hardness from 2.72–3.91 kg to 1.48–2.05 kg among the cultivars. The structural analysis indicated notable modifications in starch granules, supporting the observed changes in pasting behavior, which exhibited increased peak and breakdown viscosities. However, a reduction in antioxidant activity, viz., DPPH, TPC, TFC, and FRAP, was observed, indicating a potential trade-off between the preservation technique and nutritional quality. This study underscores the potential of freeze drying to improve the cooking and functional properties of chickpeas, with a special focus on their cooking properties. Full article

This study was aimed at providing athletes a solution to replenish the muscle glycogen re-synthesis at an optimal rate with hemp seeds as a natural protein source and Bengal gram dal and its use for the preparation of gel. The gel contains the richest source of energy, and it is an effective way to provide energy and nutrients to athletes. The gel was prepared in three variations with different hemp seed concentrations. We then analyzed the gel for pH and macronutrient composition. The sensory characteristics were analyzed for seven parameters, including appearance, taste, color, texture, aroma, consistency, and acceptability, using a hedonic scale on 25 panelists. A sensory analysis showed that sample A received an overall acceptability score of 7.16 ± 0.99 from the sensory panel. The shelf life was observed at the recommended temperature of 4 degrees Celsius, which was 12 days. The best formulation was sample B with 38 g of hemp seeds, which showed better taste, color, aroma, and acceptability and a lower average pH value (6.68 ± 1.44, 6.56 ± 1.29, 7.6 ± 1.16, 7 ± 1.26, and 5.822 ± 0.0183, respectively). Sample B contained 30.8 g of protein, 16.09 g of carbohydrates, 8.4 g of fat, and 263.16 kcal of energy per 100 g. The resulting ratio of carbohydrates to protein is optimal for use as a high-protein post-workout meal. Hence, it can be considered a post-workout supplement. Full article

This study investigated the impact of soil properties under greenhouse conditions on the growth and productivity of two chickpea (Cicer arietinum) genotypes (V1 and V2) using two distinct soils collected from Marchouch and Beni Mellal sites. Soil analysis revealed significant differences in organic matter, phosphorus, potassium, and nitrogen levels between the two sites. Marchouch soil, characterized by higher nutrient content, especially phosphorus, demonstrated a more favorable environment for chickpea growth, resulting in enhanced plant height, leaf number, chlorophyll content, seed number, and seed weight. Variety V2 showed slightly better performance than V1 across both soil types, particularly in terms of seed yield and mineral content. This research highlights the importance of soil nutrient availability. Furthermore, this study emphasizes the important role of phosphorus in chickpea growth, with Marchouch soil having a higher phosphorus level (62.9 mg kg⁻¹), significantly boosting plant development and yield. Although soil mineral characteristics and genotypes had little effect on most minerals, zinc (19.77 mg uL⁻¹) and iron (69.43 mg uL⁻¹) levels stood out as significant exceptions. Therefore, further studies should focus on examining additional soil characteristics and expanding genotype selection. Based on the findings, Marchouch soil appears to be more favorable for chickpea cultivation. However, more research is needed on the effect of soil and genotypes on Rhizobium activity. Full article

Mineral malnutrition negatively impacts almost 30% of the world population and could result in anemia, blindness, and stunted growth. Seed traits involve nutritional, physical, and physiological characteristics that play a key role in achieving seed quality. Chickpea (Cicer arietinum), the second most important food legume crop worldwide, is characterized by its rich nutrient profile, fiber, and antioxidant content. However, seed quality traits composition and daily nutritional value in chickpea seeds remain largely unknown. The objectives of the current study were to determine the variability in concentrations of macro and micronutrients, oil, protein, their correlations, and daily nutritional values (% DV) in the seeds of 61 chickpea genotypes. The results demonstrate substantial variation among chickpea genotypes in most nutrients, protein, and oil content. Moreover, this study identifies 12 promising chickpea genotypes that indicate large nutrient content and potential usage in chickpea biofortification and breeding programs. Our results further show that consumption of 100 g chickpea seeds could provide 122% DV of manganese (Mn), 77% DV of copper (Cu), 43% DV of magnesium (Mg), 32% DV of phosphorus (P), 27% DV of zinc (Zn), 26% DV of iron (Fe), and 5% DV of calcium (Ca). Overall, these findings improve our understanding of chickpea seed nutrient content as well as global food security by combatting mineral malnutrition. Full article

The seeds of some chickpea (Cicer arietinum L.) accessions are prone to sticking in twos or threes in a pod in the course of their maturation. Such seeds are usually easy to detach although their coats often become damaged due to forcible separation. Sticking is observed both in fields and glasshouses, with frequency potentially increasing in dry hot climates. Our morphometric survey of non-desi seeds (kabuli and intermediate types) suggests that it is seed shape, rather than size or color, that determines seed adhesiveness, with rounder seeds being the most prone to sticking. A similar phenomenon is known in pea (Pisum sativum L.) where it is conditioned by a single rare mutation affecting seed coat features. Unlike pea, numerous chickpea lines and cultivars of different origin have intrinsic susceptibility to seed adhesion, although to a variable extent depending on environment and seed shape, so this feature is multifactorial rather than solely genetic in C. arietinum. Although stuck seeds are mostly detached during mechanical harvesting, the accompanying seed coat lesions may be potentially undesired for seed storage and germination characteristics. Full article

This study examined the responses of four legumes—chickpeas (Cicer arietinum L.), red kidney beans (Phaseolus vulgaris L., Taishokintoki), adzuki beans (Vigna angularis), and peanuts (Arachis hypogaea)—to storage and roasting under high-temperature and high-humidity conditions (HTC beans). Roasting enhanced antioxidant activity in HTC chickpeas and peanuts, with chickpeas also showing increased resistant starch. In contrast, kidney beans showed reduced resistant starch after storage, with minimal recovery upon roasting, while refrigeration better preserved resistant starch. For adzuki beans, roasting reduced resistant starch in control samples but not in HTC samples. Reducing sugars decreased in all beans after roasting. These findings highlight roasting as a promising method for repurposing HTC chickpeas and peanuts for functional food applications. Limitations include variability among legumes and the need for further mechanistic and sensory studies. Full article

The purpose of this study was to evaluate the potential of using fuzzy C-means clustering, AMMI and GGE biplot analysis methods to predict the yield of chickpea (Cicer arietinum L.) genotypes grown in various environments. The trials were conducted in the Central, Silvan and Hazro districts of Diyarbakir province and Kiziltepe district of Mardin province in the Southeastern Anatolia Region of Türkiye. During the 2016 growing season, 19 chickpea genotypes were tested across four distinct environments. Multiple location experiments were used to assess the genotypes’ performance and stability. The study employed a two-factor experimental design in randomized blocks with four replications in each environment. As a result, the genotype FLIP98-206C showed the highest performance for yield (1727.3 kg ha⁻¹) at the Diyarbakır location among all locations. On the other hand, the Diyar-95 variety showed the lowest yield (723.5 kg ha⁻¹) at the Hazro location among all locations. The Diyarbakir location was determined as an ideal test environment for genotype selection in fuzzy C-means clustering, AMMI and GGE biplot analysis. The Silvan region was determined as the weakest environment for this purpose. It is considered that the determination of genotypes with high yield and stability in this research, in which different analysis methods were used in combination, will contribute to agricultural production.

Chickpea is among the major legume crops grown globally. In Ethiopia, it plays a vital role in the food security and economic stability of smallholder farmers. However, its production is often hampered by abiotic factors, particularly soil acidity, which is a major yet often overlooked challenge. Using tolerant genotypes alone or combined with soil amendments is a sustainable approach to improving chickpea production in acidic soils. Hence, the present study assessed the genetic variation of 64 Ethiopian chickpea accessions for acidic-soil tolerance using simple lattice design-based field experiments with two replications at two sites with acidic soil, Emdebir and Holetta. The study revealed significant genetic variation among the evaluated accessions for acid soil tolerance. The study also identified tolerant and high-yielding chickpea accessions with a high yield stability index (YSI) at both test sites. The landrace ETC_B_1_2016 exhibited the highest number of primary branches per plant (NPB), number of pods per plant (NPP), and total seed yield (TSY) at the Emdebir acidic soil trial. At the Holetta acidic soil trial, the landrace ETC_41237 recorded the highest TSY, followed by ETC_K_3_2016 and ETC_B_1_2016, while Akaki had the least. In addition, 14 accessions had the highest TSY and YSI at the Emdebir site, while 16 had the highest YSI at the Holetta site. Notably, NPP displayed the strongest positive correlation with TSY at both sites, irrespective of lime application. Higher genetic variance and broad-sense heritability observed for NPP, hundred-seed weight (HSW), and TSY suggest that genetic factors mainly influence these traits and are more likely to improve through selection. The identified acid-tolerant and high-yielding accessions could be considered for direct cultivation in areas with acidic soils, potentially increasing chickpea productivity. Additionally, these accessions can be crossbred with existing improved varieties to enhance their adaptability to acidic soils, ultimately contributing to food security in regions affected by soil acidity.
