Chickpea

life science Maturity 11-13 Next article →

The chickpea, known scientifically as Cicer arietinum, is a vital annual legume.

It belongs to the family Fabaceae and the subfamily Faboideae. This plant is highly valued globally because its edible seeds are rich in protein. Chickpeas serve as a primary ingredient in many regional diets. In Mediterranean and Middle Eastern cooking, they are used to make hummus.

They are also the base for falafel, which are fried patties made from soaked, ground seeds. In India, chickpeas are essential for various soups, stews, and curries.

In 2023, India was a massive leader in this industry. It produced 75% of the world's total chickpea supply.

The physical structure of the chickpea plant is quite distinct. The plant typically grows to a height of 20 to 50 centimeters.

It features small, feathery leaves located on both sides of the stem. The plant produces white flowers that often contain blue, violet, or pink veins. As a type of pulse, the plant develops seedpods. Each individual pod contains two or three peas.

Farmers recognize two primary varieties of the chickpea. The first is the Desi variety, often called Bengal gram.

Desi chickpeas are common in South Asia, Ethiopia, Mexico, and Iran. They are typically grown in semi-arid tropical regions. These seeds are small with a rough coat. Their colors can be black, green, or speckled. The second variety is the Kabuli chickpea.

Kabuli seeds are larger and tan-colored with a smooth coat. They are mostly grown in temperate Mediterranean and Middle Eastern regions. This variety was introduced to India from Afghanistan during the 18th century.

History shows that chickpeas are among the earliest cultivated legumes.

Humans began domesticating them roughly 10,000 years ago during the First Agricultural Revolution. This occurred alongside the cultivation of wheat, barley, and lentils. The oldest archaeological evidence was discovered in Syria. Sites like Tell El-Kerkh and Tell Abu Hureyra contain traces of chickpeas from the 8th millennium BCE.

Over time, humans used selective breeding to improve the crop. They chose plants with large, tasty seeds that were easy to harvest. They also selected for seeds that did not require a dormancy period. This process created the many varieties used today.

The scientific name Cicer arietinum has deep historical roots. Carl Linnaeus first described the plant in 1753 using binomial nomenclature. He placed it in the genus Cicer, which is the Latin term for chickpeas. This name was based on earlier works by Joseph Pitton de Tournefort. The specific name, arietinum, refers to the shape of the seed. It resembles the head of a ram.

Ancient writers like Theophrastus and Pliny the Elder also noted this resemblance. Even the Roman writer Columella discussed the plant in 64 CE.

Modern agriculture uses specific methods to increase chickpea yields. One method involves the careful use of macronutrients like phosphorus and nitrogen.

Phosphorus levels are directly linked to how tall a plant grows. Increasing inorganic phosphorus can incrementally raise the height of the plant. Scientists have found that combining phosphorus with heat treatment is very effective. This heat cultivation can increase the protein content of the chickpea almost threefold. Nitrogen is also vital, but high doses can actually inhibit the plant's yield. Balancing these nutrients is a complex task for growers.

Despite their importance, chickpeas face challenges from various pathogens.

Fungi like Fusarium oxysporum f.sp. ciceris cause significant damage. This specific fungus causes yield losses between 10% and 15% in major growing areas. Other threats include bacteria, viruses, and nematodes. For example, the Ascochyta disease is spread by wind and water splash during wet weather. Researchers are studying the plant's genome to understand these issues. They have sequenced 90 different genotypes to identify over 28,000 genes. This work helps scientists develop stronger, more resilient crops for the future.
