Welcome to
Sugarcane Research Institute

The Sugarcane Research Institute (SRI) is a statutory body established by the Act of Parliament no. 75 of 1981 (ratified on 29 December 1981), for conducting research on cultivation and processing of sugarcane to cater to technical and technological needs for the development of the sugar industry of Sri Lanka, which, until 1981 was undertaken by the Research and Development Division of the Sri Lanka Sugar Corporation (SLSC).

Crop and Resource Management

In most sugarcane varieties, elevated carbon dioxide alone does not affect photosynthesis, but the combination of elevated carbon dioxide and elevated temperature decreased photosynthesis. Elevated carbon dioxide decreases stomatal conductance and transpiration while increasing transpiration efficiency. The variable responses to elevated temperature and the significant genotypic variation to elevated carbon dioxide and elevated temperature observed, both individually and together, demonstrate a considerable scope to breed sugarcane varieties for a future high carbon dioxide and warmer climate.

Mechanization Technology

Sugarcane harvesting with dray leaves (Cane and Dry leaves Harvesting- CDLH) helps to increase manual harvesting efficiency, energy recovery, and sugar recovery. However, reengineering of the system is essential. (Read more ...)


Maturity Patterns of the sugarcane varieties are useful to schedule the planting and harvesting times. Therefore maturity patterns of sugarcane varieties introduced by Sugarcane Research Institute (SRI) from 1984-2017 are presented with the dates of planting and harvesting, and variation of pure obtainable cane sugar (POCS) with the age of the crop in different series of the varieties.

The qualitative parameters of the clarified juice vary with different preliming pH. Therefore, optimizing preliming pH according to key parameters are essential for the efficient juice clarification process. (Read more ...)
