Introduction
Arasi is a cultivar of the common mango (Mangifera indica) that is predominantly cultivated in the southern regions of India, especially in the state of Tamil Nadu and the Nilgiri hills. The fruit is prized for its distinctive sweet flavor, aromatic fragrance, and smooth, thin skin. Its cultivation has a long history that intertwines with local agricultural practices, culinary traditions, and economic activities. The cultivar is often found in markets under the name “Arasi Mango” or “Arasi” and is known for its relatively small to medium size compared to other popular varieties such as Alphonso or Haden.
Etymology and Linguistic Origins
The name “Arasi” is derived from the Tamil word “அரசி” (pronounced “arasi”), meaning “queen.” The appellation reflects the cultivar’s esteemed status among mango varieties in the region. It is sometimes alternatively spelled “Arasi” or “Arasi Mango” in local markets. The term has been in use since at least the early twentieth century, as documented in agricultural reports from the colonial period. The use of a regal title underscores the cultural reverence for the fruit’s taste and aroma.
Botanical Description
Taxonomy
Arasi belongs to the family Anacardiaceae, genus Mangifera, species Mangifera indica. Within the species, it is classified as a distinct cultivar characterized by a specific set of phenotypic traits. The scientific naming conventions recognize it as Mangifera indica L. var. Arasi, though some taxonomic authorities treat it as a cultivar rather than a formal variety. The cultivar is propagated primarily through vegetative methods to maintain its genetic identity.
Morphological Characteristics
The fruit of the Arasi cultivar typically measures 8–12 centimeters in length, with a weight ranging from 200 to 350 grams. Its skin is thin, pale yellow with a faint greenish hue during maturation, and it exhibits a smooth surface devoid of prominent lenticels. The flesh is bright yellow, fibrous to semi-fibrous, and demonstrates a high degree of juiciness. The kernel is relatively small, centrally placed, and hard, often considered non-edible. The tree itself grows to a height of 12–20 meters, featuring a moderate canopy spread. Leaf morphology is consistent with the species: lanceolate, glossy, and dark green.
Geographical Distribution and Habitat
Arasi mango trees are primarily found in the dry deciduous forests of Tamil Nadu’s interior districts, including Kallakurichi, Ariyalur, and Thanjavur. The cultivar also thrives in the cooler climates of the Nilgiri hills, where elevation ranges between 1,000 and 1,500 meters above sea level. The climate in these areas is characterized by moderate temperatures, a distinct dry season, and monsoon rainfall patterns. Soil types suitable for Arasi cultivation include loamy, well-drained, and slightly acidic soils with good organic matter content.
Cultivation Practices
Soil and Climate Requirements
Optimal growth of Arasi mangoes requires a soil pH between 5.5 and 7.0, with a moisture content that allows for adequate drainage while preventing waterlogging. The trees exhibit tolerance to moderate drought conditions but require supplemental irrigation during dry spells, especially during the flowering and fruit-filling stages. Temperature ranges of 25–35°C are considered ideal, with minimal tolerance to extreme cold or heat stress. The cultivar benefits from seasonal monsoon rains that provide essential moisture without excessive runoff.
Propagation Techniques
Arasi is primarily propagated through grafting, using the bud or scion of a mature tree onto a compatible rootstock. Grafting techniques include the side-veneer graft and cleft graft, depending on the age of the rootstock and desired outcome. Seed propagation is not commonly employed because seeds from Arasi produce genetically variable offspring, thereby losing the cultivar’s distinctive traits. Tissue culture methods have been experimented with, but grafting remains the most practical approach for large-scale cultivation.
Harvesting and Post-Harvest Handling
Harvesting of Arasi mangoes typically occurs between November and January, coinciding with the post-monsoon period. Farmers use hand-picking methods to avoid damage to the fruit’s delicate skin. Post-harvest handling involves careful washing, grading, and packaging to preserve fruit quality during transport. Cooling at temperatures of 13–15°C reduces respiration rates and extends shelf life. The typical shelf life under proper conditions is 12–18 days, after which the fruit may begin to deteriorate.
Historical Context and Cultural Significance
Historical Development in India
Arasi mango cultivation traces back to the late nineteenth century, when local farmers in Tamil Nadu experimented with cross-breeding indigenous varieties to improve yield and flavor. Historical agricultural records from the 1930s mention the Arasi cultivar as a favored fruit among rural households. The name “Arasi” likely originated from a popular local legend describing the fruit’s regal attributes, which gained popularity through oral tradition and folklore.
