Total factor productivity growth and trend in production of gram in Central India

Abstract

The study was carried out using data from various sources for growth rate and TFP estimated. The output variable used in the study was yield (kg/ha) and input variables used in the research study viz.: fertilizer (kg/ha), animal power (pair hrs/ha), manure (q/ha), human labour (hrs/ha). These data have been classified into three period’s viz. Period-I (1982-1991), Period-II (1992-2001) and Period-II (2002-2011) along with overall period (1982-2011). An overall compound growth rate (CGR) of area (1.02%/year) was observed positively and non-significant. The growth of production of gram was found positive and significant 1.7, 2.02 & 2.96 per cent per year in all the Period while at overall CGR was observed positively & non-significant 2.37 per cent per year in gram. The overall growth of input- output index and TFP was positive during the study period of 1992-2011. Shows that input as a source of growth for gram crop was found decline in case of manure, human labour & animal labour revealing that the ratio of output to input declined over the period of time but still fertilizer and seed are the principal source of growth for gram crop in Madhya Pradesh.
