This paper examines the trends in rice and maize productivity growth in Andhra Pradesh. A nonparametric data envelopment analysis (DEA) programming method is used to compute Malmquist productivity indices. For study, time-series data on cost of cultivation of selected crops were collected from the reports of Commission on Agricultural Costs and Prices for the period 1996-97 to 2014-15. The results revealed that the decomposition of the TFPch for the corresponding years into EFFch and TECHch revealed that 48.8 per cent increase in TFPch was due to improvement in the technology used. The EFFch did not affect the TFPch in overall study period i.e., there was no catching up. For the maize, the highest improvement in the performance was observed in the year 1998-99 where the TFPch was 115.9 per cent and the entire improvement was due to TECHch. This implied that there was significant improvement in the “innovation” in this year.
