Realizing the need for a sound research support for the improvement of livelihood security in the state through improvement in farm productivity, the Indian Council of Agricultural Research (ICAR), New Delhi had set up a research complex at Tadong, Gangtok (altitude 1300 m amsl) on 11th October 1976 as one of the Regional Centre of ICAR Research Complex for NEH Region, Shillong. Subsequently a Krishi Vigyan Kendra (KVK) was established at Ranipool and Saramsa (East District, Sikkim) in 1982. The research complex at Tadong is a representative location of sub-tropical and mid hills of Sikkim and act as technology generation centre while its KVK serves as technology transfer wing. The research complex has 19.96 ha land; of which 8.50 ha is under experimental crops and 2.50 ha under forests. The KVK has 6.16 ha land. The research complex has office-cum laboratory building, PCR Laboratory, library, ARIS cell, video conferencing facility, seminar hall, committee room, residential quarters, guest house, farm complex, farm store and animal sheds.

Standardization of organic package of practices for Sikkim mandarin, chillies and ginger.
DNA Fingerprinting and chemo profiling of native cultivars of ginger and chilli.
Standardization of package of practices for round the year cultivation of high value vegetable crops like tomato, capsicum, broccoli etc.
Standardization of cultivation package for temperate fruits like peach, strawberry and kiwi fruit.
Eco-friendly/organic management of insect pest and diseases of rice, maize, chillies, Sikkim mandarin ginger and large cardamom.
Cattle development- efforts are concentrated on livestock production, through artificial insemination using good quality frozen semen.
Poultry development- Introduction of high yielding layers and fast growing broilers, promotion of backyard poultry.
Pig development– introduction of fast growing breeds of pigs.
Goat development- genetic improvement for litter size through selective breeding
