Performance of pulses during pre and post-WTO period in Andhra Pradesh: district wise analysis

The present study was attempted to cluster the districts based on different criterion, estimating the patterns of growth and magnitude of instability, and assessing the explanatory variables' affects on pulses production in Andhra Pradesh. The time series data for the period 1986–87 to 2007–08 on area, production and productivity were collected from various publications of the Bureau of Economics and Statistics, Government of Andhra Pradesh. Hierarchical and K-Means Clustering, Compound Growth Rate (CGR), Coppock's Instability Index (CII), and decomposition analysis (change in average production) were employed for achieving the objectives. Growth performance of pulses production was high, but it was accompanied by high degree of instability. Decomposition analysis revealed that area effect was marginally higher than the productivity effect on the production differential. Therefore, growth in production should mainly come from area attributing factors like assured supply of farm inputs and provision of remunerative prices.
