About Litchi
- Litchi is a juicy subtropical fruit belonging to the Sapindaceae family and is widely valued for its flavour and commercial importance.
- India is the second-largest producer of litchi in the world after China, while other major producers include Thailand, Australia, South Africa, Madagascar, and Florida in the United States.
- In India, large-scale cultivation is concentrated in states such as Bihar, West Bengal, Uttar Pradesh, Jharkhand, and Assam.
- Shahi Litchi of Bihar received the Geographical Indication (GI) tag in 2018, recognising its unique quality, aroma, and geographical origin associated mainly with the Muzaffarpur region.
- The crop grows best in a moist subtropical climate and is generally cultivated in low-elevation areas, though it can be grown up to about 800 metres above sea level.
- Litchi cultivation requires deep, well-drained loamy soil rich in organic matter, with an ideal soil pH ranging between 0 and 7.0.
- The plant is sensitive to extreme climatic conditions, especially frost during winter and dry heat during summer.
- For healthy growth and fruit production, summer temperatures should remain below 5°C, while winter temperatures should not fall below the freezing point.
- Excessive or prolonged rainfall, particularly during the flowering stage, can negatively affect pollination and reduce fruit yield.
- Young litchi plants require protection from hot winds and frost during the initial years until they become fully established.
