The broad objective of the above adaptive research programme is to introduce a crop management package to increase the resilience of tea crops to climate change and other biotic and abiotic stress factors. The overall management package has two components. One component focuses on the nursery stage and includes certain selected measures to produce a vigorous seedling for planting in the field. The second component focuses on introducing certain selected management practices in the field to improve the climate resilience/stress resilience of established tea crops.

The research is at present effective in tea fields at the seven estates managed by Upper Kahawatte Plantations Ltd. in the Nawalapitiya region.
The ongoing filed treatments of the proposed management package has initiated with 12,500 nursery cuttings since April 2018 at Kataboola Estate.
