To give proper attention to research on spices, an independent All India Co-ordinated Research Project (AICRP) on spices was started in 1986. which aims to evolve disease and pest resistant varieties,standerdise agricultural techniques to suit different climatic conditions of the country , developing a proper network between different agencies involved in research on spices. A regional station of the Central Plantations Crop Research Institute (CPCRI) was started in1976 specifically for spice research and on 1st July 1995, the centre was upgraded to the Indian Institute of Spices research. To assist farmers meet today's challenges and to encourage to increase export potential, the Spice Board is developed, many schemes are launched by the board.
