Chickpea/Gram pea Stems play an essential role in supporting the overall structure of the plant and transporting water, nutrients, and sugars between the roots and leaves. Chickpea stems are typically slender, cylindrical, and herbaceous (non-woody). They emerge from the main root system and grow upwards, branching out into various side shoots as the plant matures.
The color of chickpea stems is usually green when they are young and actively growing. As they mature, they may become slightly reddish or brownish at the base. Chickpea stems have a relatively smooth texture, with shallow ridges or furrows running lengthwise along the surface. Chickpea plants exhibit an erect growth habit, meaning that the stems grow vertically, standing upright.
The stems of chickpea plants have nodes, which are the points on the stem where leaves, buds, or flowers emerge. These nodes are spaced at regular intervals along the stem.Some chickpea varieties may produce tendrils that emerge from the leaf axils. Tendrils are slender, coiling structures that help the plant attach to nearby support structures for stability.
Chickpea stems are relatively delicate compared to other woody plants, but they are crucial for the plant’s growth, supporting the leaves and reproductive structures while facilitating the transport of essential nutrients throughout the plant.
The Economic Importance and Uses of Chickpea/Gram Pea Stems
Below are the Economic Importance of Chickpea Stems:
1. Structural Support: The stems of chickpea plants provide structural support to the entire plant. They play a crucial role in maintaining the plant’s posture and ensuring that the leaves receive adequate sunlight for photosynthesis.
2. Biomass and Mulch: After harvesting the chickpea pods, the stems can be collected and used as biomass for energy production. Additionally, they can be turned into mulch, which helps retain moisture in the soil and suppress weed growth in agricultural fields.
3. Animal Bedding: The dried stems can be used as animal bedding material, providing a comfortable and absorbent surface for livestock.
4. Fiber Production: In some regions, the fibers from chickpea stems can be extracted and used for making ropes, baskets, or other handicrafts.
5. Green Manure: Chickpea stems, along with the rest of the plant, can be plowed back into the soil as green manure. Green manure refers to the practice of incorporating plant material into the soil to improve its fertility and structure. As the chickpea stems decompose, they release nutrients and organic matter, enhancing the soil’s health and productivity for subsequent crops.

9. Ethnobotanical Uses: Chickpea stems might hold cultural significance in certain regions and be utilized for ceremonial purposes or traditional rituals..
The Products and By-products That Can Be Derived From Chickpea/Gram Pea Stems
Chickpea, also known as gram pea or garbanzo bean, is a leguminous plant that produces not only the well-known edible seeds but also various parts that can be utilized to create different products and by-products.
Here are some examples:
1. Chickpea Seeds (Product): The most common product derived from chickpeas is the edible seeds themselves. These seeds can be used in various culinary applications, including salads, soups, stews, curries, and hummus. They can be consumed whole, cooked, sprouted, or ground into flour to make chickpea-based dishes like falafel or gram flour (besan).
2. Chickpea Flour (Product): Chickpea stems can be used to make chickpea flour by drying and grinding them into a fine powder. Chickpea flour, also known as gram flour or besan, is a gluten-free alternative to wheat flour and is commonly used in Indian, Middle Eastern, and Southeast Asian cuisines. It is used to make a variety of dishes like pakoras, socca, and various gluten-free baked goods.
3. Animal Feed (Product): Chickpea stems, along with other agricultural residues, can be used as animal feed. They can be dried, chopped, and processed to provide supplementary feed for livestock, contributing to their nutrition and health.
4. Biomass (By-product): After the seeds are harvested, the remaining chickpea stems can be used as biomass. Biomass refers to organic matter that can be used as fuel for energy generation. The stems can be burned or processed to produce bioenergy, such as biofuels, biogas, or electricity.
5. Mulch (By-product): Chickpea stems can be collected and used as mulch in agricultural practices. Mulching involves spreading a layer of organic material over the soil surface, which helps retain moisture, suppress weeds, and improve soil structure. Decomposing chickpea stems also enrich the soil with organic matter and nutrients.
6. Compost (By-product): Similarly, chickpea stems can be composted along with other organic waste to create nutrient-rich compost. Compost is an excellent natural fertilizer that can be used to improve soil fertility and promote plant growth in gardens, farms, and horticultural settings.
7. Craft Materials (By-product): Chickpea stems, due to their fibrous nature, can be used for crafts and DIY projects. They can be woven, braided, or used as decorative elements in various handicrafts.
8. Bioactive Compounds (By-product): Chickpea stems, like other plant materials, may contain bioactive compounds such as polyphenols, flavonoids, and antioxidants. These compounds have potential health benefits and can be extracted from the stems for use in the food, pharmaceutical, or cosmetic industries. For example, they could be incorporated into dietary supplements, functional foods, or natural skincare products.
