PLACROSYM is the abbreviation for Plantation Crops Symposium, which is a series of scientific conferences held in India at different locations.

Background
A preliminary Symposium on Plantation Crops was as held in 1972 at Trivandrum, which should be accounted as the mother for all later Plantation Crops Symposia.
Its proceedings were published 1973 as a supplement to Journal of Plantation Crops. Although this preliminary symposium is entitled First National Symposium on Plantation Crops, it is not counted to the series of the later PLACROSYM's.

Later, in 1978, the title for National Symposium on Plantation Crops was modified as Annual Symposium on Plantation Crops, indicating an annual appearance up to PLACROSYM V.

From PLACROSYM VI, these series of symposia were held biennially at different research institutions engaged in research and development of plantation crops. The objective of this symposium is to provide a common forum for interaction among the scientists and extension officers who are engaged in plantation crops research and development. The symposium also provides the platform for exchanging scientific ideas and technologies developed in various member institutions and to put in a collective thought for the overall development of the plantation sector. Further, it offers opportunity for the young scientists to acquire scientific knowledge and modern technologies through inspiring lectures by experts and participating in thought provoking discussions.
