Trends, growth and variability of Bengal gram in Andhra Pradesh

Abstract: 

The main objectives of the study are to examine the trends in area, production and productivity of Bengal gram in Andhra Pradesh over a period of 1987-88 to 2006-2007. Compound growth rates of area, production and productivity were estimated by fitting semi log trend equation. Decomposition of output growth of groundnut was examined by fitting component analysis model. The compound growth rates of area production and productivity of Bengal gram over the period shows positively significant. The study also confirms the magnitude of variability in production of Bengal gram. The synchronized movements in area and productivity both was responsible for low instability / variability in Bengal gram of Andhra Pradesh. Further, the study conducted a decomposition analysis to determine the contribution of different components to the growth rate. The decomposition analysis revealed that in the total production of Bengal gram was completely due to the change in area under the crop as the yield and interaction effects were very small.
