Growth and instability in area, production and productivity of Red gram in Vidarbha region of Maharashtra

Abstract

The present study has been conducted to analyse the growth and instability in area, production and productivity of Red gram in Vidarbha region of Maharashtra. The time series data of area, production and productivity of Red gram of all the districts of Vidarbha were collected from various government publications, reports and related websites. For analysing the performance of Red gram, the statistical tools like Absolute change and Relative change, Compound growth rate, Coefficient of Variation and Coppock’s Instability Index were worked out. The results concluded that the significant increase in the growth rate of area of Red gram was noticed in Gadchiroli district followed by Bhandara and Chandrapur district at the rate of 7.22, 3.82 and 2.88 percent per annum respectively. Additionally, the districts of Chandrapur, Gadchiroli, and Nagpur had the fastest increase rates in red gram production, with annual growth rates of 9.69, 7.87, and 4.06 percent, respectively. However, Chandrapur district was the only one to record notable increases in Red Gram productivity, with annual growth rates of 6.62%. The growth rates of area and production of Red gram were found positive and significant for Nagpur division as a whole whereas non-significant for Amravati division. It is observed that, the highest variation and instability of Red gram was observed in Akola district whereas the highest instability is observed in Gadchiroli and Chandrapur districts.
