Chickpea: the story on HearLore | HearLore
Chickpea
The chickpea is named for its uncanny resemblance to the head of a ram, a detail that has persisted in human language for over three thousand years. This small, tan seed, scientifically known as Cicer arietinum, is not merely a vegetable but a historical witness to the dawn of agriculture. Archaeological evidence from Tell El-Kerkh in modern-day Syria reveals traces of cultivated chickpeas dating back to the 8th millennium BCE, making it one of the very first crops to be domesticated by human hands. While wheat and barley often steal the spotlight in discussions of the First Agricultural Revolution, the chickpea was cultivated alongside them, surviving the harsh winters and hot summers of the Fertile Crescent to become a staple for early hunter-gatherer societies transitioning into settled farmers. The specific epithet arietinum, meaning ram-like, was coined by the Roman writer Pliny the Elder, who noted the seed's shape, but the connection to the animal predates Latin by millennia, appearing in the ancient Greek word krikos and the Old Prussian word cicer, which retained the meaning of the seed even as languages diverged across the Pontic-Caspian steppe between 4,500 and 2,500 BCE. This linguistic thread connects the ancient Pelasgians of north Greece to the modern English speaker, proving that the chickpea has been a constant companion to humanity since the Neolithic Era.
The Linguistic Journey of a Seed
The story of the chickpea is written in the very words we use to describe it, tracing a path from the Proto-Indo-European roots of the Pontic-Caspian steppe to the modern kitchen. Historical linguistics have uncovered ancestral words relating to chickpeas in the prehistoric Proto-Indo-European language family, where roots denoting both the kernel of a legume and a pea appeared before the great migrations of 4,500 to 2,500 BCE. As speakers of this language became isolated, their dialects diverged, creating a complex web of names that still exists today. The Latin word cicer evolved into the Spanish word garbanzo, the French word pois chiche, and the Italian word ceci, while the Old Prussian word retained the original meaning of the seed. In the Americas, the term garbanzo appeared in writing as early as 1759, derived from the Spanish, while the English word pea itself evolved from the singular and plural word pease, which eventually lost its plural s to become the modern singular form. The Greek word krikos, mentioned in The Iliad around 800 BCE, and the Old Armenian word for chickpeas, which appeared before 400 CE, further illustrate how this single plant has woven itself into the fabric of global culture. Even the word falafel, now a global favorite, has roots in the Arabic word for chickpeas, hummus, which was used to describe the ground paste mixed with sesame seed paste. This linguistic diversity reflects the plant's journey from the wild fields of Turkey and Syria to the tables of India, Europe, and the New World, where it was introduced by Spanish and Portuguese explorers in the 16th century.
What is the scientific name of the chickpea plant?
The scientific name of the chickpea plant is Cicer arietinum. This species belongs to the family Fabaceae and is known for its tan, edible seeds.
When were chickpeas first domesticated by humans?
Archaeological evidence from Tell El-Kerkh in modern-day Syria reveals traces of cultivated chickpeas dating back to the 8th millennium BCE. This makes the chickpea one of the very first crops to be domesticated by human hands.
Where did the word chickpea originate from?
The name chickpea comes from the Latin word cicer, which was coined by the Roman writer Pliny the Elder to describe the seed's ram-like shape. The connection to the animal predates Latin by millennia, appearing in the ancient Greek word krikos and the Old Prussian word cicer.
Which country produces the most chickpeas in the world?
India accounts for 75% of global chickpea production in 2023. Australia has emerged as a major secondary producer of the crop.
What are the nutritional values of cooked chickpeas?
Cooked chickpeas contain 60% water, 27% carbohydrates, 9% protein, and 3% fat, supplying 164 calories per 100 grams. They are a rich source of folate, providing 43% of the Daily Value, and manganese, providing 45% of the Daily Value.
How does drought stress affect the growth of chickpeas?
Drought stress has a strong effect on the growth of the plant, with trials showing that Cicer arietinum differs from other plant species in its capacity to assimilate mineral nitrogen supply from the soil during drought stress. The plant is native to the dry Middle-Eastern region where it is most commonly cultivated.
The transformation of the chickpea from a wild plant to a domesticated crop was a deliberate process of selective breeding that took place over thousands of years. The closest evolutionary relative to the cultivated chickpea is Cicer reticulatum, a plant native to a small area in southeastern Turkey and nearby Syria, which was harvested by ancient hunter-gatherer cultures before 7500 BCE. The process of domestication involved selecting plants that produced large, palatable seeds without a dormancy period, seeds that were easy to separate from their pods, and plants with a predictable ripening period to allow entire fields to mature at once. This selective breeding produced several different varieties, including the desi and kabuli types, which differ in size, color, and coat texture. In Greece, Theophrastus wrote about these varieties in Historia Plantarum, noting that chickpeas differed in size, color, taste, and shape, with some called rams and others vetch-like. A key selection factor was the shift from winter sowing to spring sowing, as growing in the damp winter months made crops vulnerable to Ascochyta blight, a fungus that caused regular crop failures. By the Hellenistic period and the time of the Roman Empire, summer cropping of chickpeas was being practiced, allowing farmers to avoid the wet conditions that favored the disease. This adaptation was crucial for the spread of chickpea cultivation to the west, reaching present-day Greece by the late Neolithic Era, and to the east, where specimens from 1900 BCE were found at Tell Bazmusian. The domestication of the chickpea was not just about yield but about survival, allowing the plant to thrive in the hot, dry summers of the Near East and the damp winters of Europe.
The Global Table of the Ancient World
Chickpeas have been a cornerstone of Mediterranean and Middle Eastern cuisines for millennia, appearing in dishes that range from humble street snacks to elaborate feasts. In the Middle East, chickpeas are roasted, spiced, and eaten as a snack known as leblebi, while in India, they are used to make curries, salads, soups, and stews, serving as one of the most popular vegetarian foods in the subcontinent. The Arabic word hummus, which means chickpeas, describes the paste made by cooking and grinding the seeds with tahini, a sesame seed paste, and by the end of the 20th century, hummus had become common in American cuisine, with 5% of Americans consuming it regularly by 2010. In Portugal, chickpeas are a main ingredient in rancho, eaten with pasta, meat, or rice, and in Spain, they are used cold in tapas and salads, as well as in cocido madrileño. The plant's versatility extends to the Philippines, where chickpeas preserved in syrup are eaten as sweets and in desserts such as halo-halo, and to the Ashkenazi Jewish tradition, where whole chickpeas, referred to as arbes in Yiddish, are served at the Shalom Zachar celebration for baby boys. The chickpea's journey to the New World began in the 16th century when Spanish and Portuguese explorers introduced it to the Americas, where it was adopted into local cuisines and became a staple in regions like Mexico, where guasanas or garbanza is a popular street snack. The plant's ability to adapt to different climates and culinary traditions has made it a global icon, with India accounting for 75% of global chickpea production in 2023, and Australia emerging as a major secondary producer.
The Science of Survival and Yield
Modern research into the chickpea has revealed a complex interplay between genetics, environment, and disease that continues to shape its future. The genome of 90 chickpea genotypes has been sequenced, including several wild species, and a collaboration of 20 research organizations led by the International Crops Research Institute for the Semi-Arid Tropics has identified more than 28,000 genes and several million genetic markers. Despite these advances, the stagnation of yield improvement over the last decades is linked to the plant's susceptibility to pathogens, which can cause yield losses of up to 90%. One example is the fungus Fusarium oxysporum f.sp. ciceris, present in most major pulse crop-growing areas and causing regular yield damages between 10 and 15%. The emergence of Ascochyta rabiei, a disease favored by wet weather, has been a persistent challenge, with spores carried to new plants by wind and water splash. Research has started selecting favorable genes for pathogen resistance and other traits through marker-assisted selection, a promising method for achieving significant yield improvements. The plant's growth is also influenced by environmental factors such as heat cultivation and macronutrient coupling, with a combination of heat treatment and the vital macronutrients phosphorus and nitrogen being the most critical component to increasing overall yield. The level of phosphorus that a chickpea seed is exposed to during its lifecycle has a positive correlation relative to the height of the plant at full maturity, while high doses of nitrogen can inhibit yield. Drought stress, a native characteristic of the dry Middle-Eastern region where the chickpea is most commonly cultivated, has a strong effect on the growth of the plant, with trials showing that Cicer arietinum differs from other plant species in its capacity to assimilate mineral nitrogen supply from the soil during drought stress.
The Nutritional Powerhouse
Cooked chickpeas are a nutritional powerhouse, containing 60% water, 27% carbohydrates, 9% protein, and 3% fat, and supplying 164 calories per 100 grams. They are a rich source of folate, providing 43% of the Daily Value, and manganese, providing 45% of the Daily Value, making them a moderate source of thiamine and several dietary minerals. The consumption of chickpeas is under preliminary research for the potential to improve nutrition and affect chronic diseases, with studies showing that cooking treatments do not lead to variance in total protein and carbohydrate content. Soaking and cooking of dry seeds possibly induces chemical modification of protein-fibre complexes, which leads to an increase in crude fiber content, thus increasing protein quality by inactivating or destroying heat-labile antinutritional factors. Cooking also increases protein digestibility, essential amino acid index, and protein efficiency ratio, although it lowers concentrations of amino acids such as tryptophan, lysine, total aromatic, and sulphur-containing amino acids, their contents are still higher than proposed by the FAO/WHO reference. The plant's leaves, which are consumed as cooked green vegetables in some parts of the world, have a significantly higher mineral content than either cabbage leaves or spinach leaves, and can supplement important dietary nutrients in malnourished populations. The chickpea's ability to improve protein digestibility through germination, which degrades proteins to simple peptides, and its role as an energy and protein source for animal feed, make it a valuable crop for both human and animal nutrition. The plant's secondary components, such as lecithin, polyphenols, oligosaccharides, and trypsin and chymotrypsin inhibitors, can lead to lower nutrient availability and impaired growth in nonruminants, but ruminants generally have less trouble digesting legumes with secondary components since they can inactivate them in the rumen liquor.
The Future of a Global Crop
The future of the chickpea lies in the balance between genetic research, environmental adaptation, and global demand. As the world's population grows, the need for sustainable, high-protein crops like the chickpea becomes increasingly critical, with India accounting for 75% of global production and Australia emerging as a major secondary producer. The plant's ability to thrive in semi-arid tropics and temperate regions makes it a valuable crop for regions facing climate change and water scarcity. Research into heat cultivation and macronutrient coupling, such as the combination of heat treatment and the vital macronutrients phosphorus and nitrogen, is the most critical component to increasing overall yield. The plant's growth is also influenced by environmental factors such as drought stress, which has a strong effect on the growth of the plant, with trials showing that Cicer arietinum differs from other plant species in its capacity to assimilate mineral nitrogen supply from the soil during drought stress. The stagnation of yield improvement over the last decades is linked to the plant's susceptibility to pathogens, which can cause yield losses of up to 90%, but research for yield improvement, such as an attempt to increase yield from 1.5 to 2.5 tonnes per hectare by breeding cold-resistant varieties, is always linked with pathogen-resistance breeding. The plant's versatility, from its use in hummus and falafel to its role as animal feed, makes it a valuable crop for both human and animal nutrition, and its future depends on the continued efforts of researchers, farmers, and consumers to ensure its survival and prosperity in a changing world.
