Buchanania lanzan, commonly known as Chironji, stands as a vital multipurpose tree species flourishing in Central India. Noteworthy for its hardy nature, this tree boasts kernels with high commercial value and is acclaimed for its medicinal properties. Unfortunately, owing to a confluence of natural and human-induced factors, Chironji faces a looming threat, resulting in its classification as a species under threat.
To counteract the decline of Chironji, a strategic approach involves its domestication in the fields of local farmers. Despite its potential to generate substantial income and employment opportunities, farmers have been slow to adopt its cultivation on their lands.
Addressing the disconnect between demand and supply necessitates the integration of Chironji into the agroforestry system, particularly in Central India. The species exhibits favorable interactions with various crops, signaling its compatibility with agroforestry practices.
Engaging in Chironji-based agroforestry stands as a pivotal measure to boost farmers’ income and ensure livelihood security. Planting this species at an optimal spacing of 10-12 x 10-12 meters allows for the successful cultivation of diverse oilseeds, pulses, and select cereal crops between tree rows.
While propagation commonly relies on seeds, the challenge of a hard seed coat hindering germination can be overcome through pre-treatment methods. Mechanical breaking of the seed coat with a light hammer proves effective in promoting optimal germination.
By adhering to sound cultural practices, farmers can anticipate a robust Chironji yield approximately 10-12 years post-planting. Given the accelerated depletion of this species, prioritizing Chironji and advocating for widespread plantation in farmers’ fields within the agroforestry system, especially in Central India, becomes imperative. The species holds immense potential for securing livelihoods and presents a compelling opportunity for large-scale cultivation in the region.

Vegetative Propagation Methods for Chironji Regeneration
Chironji is a valuable plant with versatile applications. To ensure its sustainable regeneration, various vegetative propagation methods can be employed. Let’s explore these methods and understand their advantages and applications in the context of Chironji cultivation.
Soft Wood Grafting
Soft wood grafting proves to be a viable method, especially in gravelly soils and drier tracts where nursery-raised grafts face high mortality rates. The process begins with freshly extracted seeds sown in polythene bags for germination. Once the seedlings reach a height of 5-10 cm, they are directly planted in the field at the desired distance. After one year, the vigorous seedlings, with pencil-like thickness, undergo soft wood grafting with scion sticks of suitable genotype. This method offers better plant growth and minimizes mortality, making it a resilient choice for Chironji orchards.
Chip budding stands out as a successful method for vegetative propagation of Chironji. In this technique, a healthy bud is carefully selected from the axil of a 2-month-old leaf emerging on a new flush. The leaf blade is removed, leaving the petiole intact. A precise series of cuts are made on the rootstock, and the bud is placed at the juncture, ensuring a secure fit. After careful tying and union, the top of the seedling is pruned above the bud union. Chip budding, when executed with precision and proper selection of scion and rootstock, can yield appreciable success during the months of July and August.
Root cutting, though challenging due to poor seed viability and slow seedling growth, can be successful with the use of growth hormones like auxins. Two-year-old root cuttings treated with IAA (1600 ppm) recorded a notable 67.66% rooting success. While rooting in root cuttings can be difficult, the application of growth hormones enhances the chances of success, providing an alternative avenue for Chironji regeneration.
Root cuttings offer varying degrees of success, but their use is limited due to the potential for serious injury to the plant when large amounts are taken. Additionally, the absence of the taproot affects longevity. The protocol for this method involves carefully removing a few roots on opposite sides to minimize harm to the plant. While successful, it is essential to consider the potential drawbacks and use this method judiciously.
Using root stock as a method of vegetative propagation is an effective means of controlling vigor and maintaining equilibrium between yield and quality. This method, considered as a good approach for Chironji, provides a balanced way to propagate and ensure the desirable traits of the plant.
In conclusion, the choice of vegetative propagation methods plays a crucial role in the successful regeneration of Chironji. Whether through soft wood grafting, chip budding, root cutting, or root stock, each method has its merits and considerations. By understanding and applying these techniques, we can contribute to the sustainable cultivation and propagation of this valuable plant.
Potential and Sustainable Harvesting
While Chironji offers numerous benefits, its natural regeneration faces challenges due to high seed extraction. Sustainable harvesting protocols are essential to enhance the species’ regeneration. Determining the best harvesting period, typically the 2nd week of May, ensures optimal results in seed size, weight, germination, and oil content.
Challenges in Artificial Regeneration
Artificial regeneration of Buchanania lanzan presents challenges, including low germination rates due to fungal contamination. Fungal attacks, especially by Fusarium sp., are common post-sowing, emphasizing the need for meticulous storage and planting conditions.
Enhancing Germination and Plant Survival
Overcoming challenges, breaking the hard seed coat before sowing significantly improves germination rates. Planting one-year seedlings in well-prepared pits with proper mulching enhances plant survival, ensuring satisfactory growth even in adverse conditions.
Ensuring Future Regeneration
With a long gestation period of 15-20 years and large genetic variability, ensuring the future regeneration of Chironji requires breeding operations. Plant tissue culture emerges as a promising technology for mass germplasm propagation, offering a sustainable solution for the species.
Beyond its culinary appeal, Chironji stands out as a remarkably nutritious nut with a myriad of health advantages. By understanding its nutritional value and addressing regeneration challenges, we can ensure the continued availability of this valuable and versatile resource.
Chironji, with its delightful taste and nutritional richness, proves to be more than just a culinary delight. From serving as a healthful snack to being a substitute for almonds in confectionery, its applications are diverse. Understanding its nutritional content and addressing challenges in regeneration opens the door to a sustainable future for this remarkable nut. So, why not make Chironji a regular part of your diet, enjoying both its taste and the benefits it brings to your well-being?
Conservation Challenges and Strategies for Chironji
