Abstract

The present study deals with the temporal changes, growth & instability in the exports of agricultural commodities from 1962–94. The exponential function was used to compute the growth rates and instability indices. The growth in export of fruits and vegetables, oilseeds, fish and fishery products and feeding stuff for animals have been remarkable in early nineties as compared to previous decade (1980–90). The export 01 cereals and cereal preparations, and sugar and honey were observed to be most volatile in the last two decades. Both total merchandise and agricultural sector trade are showing deficit since 1962–65 but trade in agricultural sector turned to surplus of $ 1349 million in 1990–94, indicating positive impact 01 new Iiberalised trade policies.
