Analysis of growth trends in area, production and yield of tea in Bangladesh

The Growth trends in area, production and yield of a crop express its contribution to the economy. The present study seeks to examine the growth rates of area, production, and yield of tea in Bangladesh before independence (1947–1970) and after independence (1972–2018). To carry out the objectives the secondary data were collected from the various issues of the Annual Report of Bangladesh Tea Association and International Tea Committee. The exponential growth model was run to estimate the growth of the area, production, and yield of tea. The study showed that on average area, production and productivity increased significantly @ 1.05, 1.89, and 0.98% respectively per annum during the period of 1972–2018 than the period of 1947–1970. Area expansion and yield were the main vehicles for increased tea production. Therefore, the thrust should be given to increase the area by utilizing the suitable area and to increase the yield through technological advancement, varietal research, and strengthening advisory services in Bangladesh.
