Compound Annual Growth (CAGR) Rate of Fresh Tea Leaf (Camellia sinensis) Production in Assam : A Statistical Approach

The present study aims at estimating compound annual growth rate of tea in the state of Assam and Sonitpur district of Assam. The study was based on secondary data, which were collected from various published and unpublished sources. The data related to area, production and productivity of green tea leaves were collected for the period of 2003-04 to 2017-18. For detailed analysis, the whole period was divided into three sub-periods i.e., period I (2003-04 to 2007-08), period II (2008-09 to 2012-13) and period III (2013-14 to 2017-18). The overall compound growth rates of area under tea for both the state of Assam and the district of Sonitpur were positive (0.06 per cent and 1.19 per cent respectively). But negative growth rate (-1.03 per cent) was found in area for the state in period-III (2013-14 to 2017-18). Compound annual growth of production of green tea leaves was found positive in overall period for both the state and the district. But negative growth rate (-1.86 per cent) in production was found in period-I (2003-04 to 2007-08) for the district. Productivity also showed similar trend in comparison with production. The overall growth rate of productivity was positive for both state and the district
