The study was carried out on “Decomposition analysis of cereals production In Nagpur Division” during year 2014-2015. The main objectives of the study were to work out Growth rate and instability of area, production, productivity of selected cereals crop. In Maharashtra particularly in the Nagpur division of Maharashtra no such studies have been attempted so far, the Nagpur division on Maharashtra being an agrarian region, it has a wide scope for such studies. That’s way formulating valuable planning polices of agriculture of this region, the present investigation was undertaken to study to growth rate in area, production and productivity of important cereal crops viz; wheat and rice for period from 1995-96 to 2014-15. The study also focused attention on the inter district variation of selected crops and instability were also estimated in the study. The time series data relating to the aspects of study were collected for the above period from the published literature as well as from other relevant sources. The data were analyzed by fitting exponential function to estimate the compound growth rate, the decomposition analysis model (Minhas 1964) was used in the present study. The study concluded that compound growth rate for area and production under cereals has increase in some district of Nagpur division of Maharashtra during study period. The study revealed that the compound growth rate of wheat production in period I and period II was same in Nagpur division as whole. The Highest compound growth rate for area of rice was recorded in Wardha district is 23.16 per cent per annum followed by Nagpur district (3.69 per cent). The Chandrapur district was recorded the lowest instability (3.25 per cent) for area under rice 3.25 in period I. Compound growth rates of production of wheat was 4.18 per cent in Nagpur division. The area, production and productivity instability in cereals was observed in almost all districts in the state. It may be because the crop largely depends on vagaries of nature which causes heavy losses. Percent contribution of yield effect was more responsible for production of the selected cereals. Maximum instability was found in the overall period for selected cereals crops. For trend analysis among the competitive parametric models, in all district the area, production and productivity for wheat and rice only the cubic models are found best fitted.
