Growth and instability of sorghum in vidarbha region

Sorghum is the fifth most important cereal crop in the world. However in India it is third cereal crop after rice and wheat. It was one of the major cereal staple during 1950 but recently its area came down. The present study based on the last 30 year time series data on area,production and productivity to identify the trend. The compound growth rate and coefficient of variation here analysed for period I (1985-86 to 1999-2000), period II(2000-2001 to 2014-15) and overall 30 years (1985-2015) for the major five districts of Vidarbha region .The study indicate that compound growth rate for area, production and productivity for almost all the district where negative highest decline in the sorghum area is observed in Yavatmal district followed by Amravati and Buldhana district. i.e82.75, 78.96 and 77.84.percent per annum during the last 30 years i.e. overall production found to be statistically significant at 1 percent level of probability with the highest coefficient of variation is observed in wardha district followed by akola and chandrpur i.e. 75.34, 74.02 and 69.62 percent. The coefficient of variation for almost all the district were less in period I as compared to period II. The similar pattern also observed in production. On the other hand the growth rate of productivity for the Sorghum was positive for almost all the district and both the period . Highest compound growth rate for productivity during the overall period was observed in wardha followed by akola ,chandrapur i.e. 15 percent per annum with coefficient of variation range in between 28.44 to 41.30 percent. Thus it is concluded that Sorghum is declining during the study period. Considering the importance of Sorghum as a low input crop and the staple food it is recommended option for the farmer in operating in any environment where other crop not performing well. On the other hand sweet Sorghum was specially used for bioethanol production which is blended with petrol, In the developing and developed economies it is need to concentrate on the crop specially to cultivate under marginal and stress prone areas to attend the sustainability.
