"Analysis of Growth Trends of Isabgolin Rajasthan - An Overview"

Abstract

The growth trends in area, production and productivity of isabgol in Nagaur district and in the Rajasthan state as a whole have been estimated by the three growth rate functions/models like linear, semi-log and compound models. The estimates of growth rates pertained to the period from 2009-10 to 2018-19. In this analysis, semi-log growth function was found to bebest fitted model as it is having highest value of R2 (coefficient of determination) and lowest value of RMSE (root mean square error). Findings showed that growth trends in area, production and productivity of isabgol in Nagaur district were significantly increased at a semi-log growth rate of 6.18, 10.34 and 6.31 per cent per annum during the study period, respectively. In Rajasthan state as a whole for the period 2009-10 to 2018-19, growth rates in area, production and productivity of isabgol were found significantly positive at the rate of 9.55 per cent per annum in area, 15.85 per cent per annum ain production and 6.18 per cent per annum in productivity, respectively. The result of the study indicated that the increase in production was attributed to the area and productivity of isabgol crop in Nagaur as well as Rajasthan state. It may be recommended that there is a need to increase the productivity of the crop mainly by developing improved varieties of isabgol suiting to the changing agro climatic condition of the state.
