Abstract

Present investigation was undertaken to study the growth rate and instability of area, production and productivity of Cotton crop. The study was based on secondary data for the period of 23 years (1984–85 to 2006–07) for the districts viz., Buldana, Yavatmal, Akola, Amravati and Amravati division as a whole of western Vidarbha of Maharashtra state. The growth rate of cotton in all most all districts of Ambravati division and also division as a whole was found to be drastically decline in period-II as compared to period-I, except Akola district. The highest compound growth rate of cotton productivity was noted in Akola district (i.e. 9.78 per cent per annum) followed by Buldhana and Amravati district. During the overall period i.e. 23 year as a whole, Yavatmal recorded lowest degree of instability in area, 9.80 per cent Coefficient of variation (CV) and 11.09 per cent Coppock's instability index (CII) indicates least consistency in terms of area during overall twenty three years. Whereas, Akola recorded highest instability for production and yield i.e. 38.75 and 65.72 per cent CV respectively.
