Description The present study entitled “Study of Fertilizer Consumption Pattern in Prakasam and
Nellore Districts of Andhra Pradesh” had been attempted to identify the trends with shifts in
fertilizer consumptions, to identify the determinants of fertilizer consumption and developing
forecasting model for fertilizer consumptions. The reference period of study was from 1977-78 to
2008-09 and the study was carried out for the Prakasam and Nellore Districts of Andhra
Pradesh.
Trends in Fertilizer consumption, Total cropped area, Gross irrigated area, Rainfed area
were identified by computing compound growth rates. However, the time series data on these
dependent variables exhibited a discontinuity over the study period. Hence, the growth in fertilizer
consumption was measured after identifying the period of discontinuity which leads to formation of
sub periods in the data. These years of discontinuity or shifts were identified by the graphical
approach (control charts).
The determinants of fertilizer consumption were identified by multiple linear regression
using non-price factors like Total cropped area, Rainfed area, Gross irrigated area.
The conventional trend models were fitted to the season wise fertilizer consumption and the
best fitted models for forecasting the fertilizer demand were identified based on significant Adj R2
and least Residual Mean Square (RMS).
The study revealed that the N, P, K and NPK total fertilizer consumption marked a
significant increasing trend for the Prakasam and Nellore Districts of Andhra Pradesh. In both
districts phosphate showed high compound growth rate compared to remaining three i.e., N, K,
NPK total. Phosphate consumption recorded highest compound growth rates i.e., 8.32 ,6.94 in
Prakasam and Nellore districts respectively. The total NPK fertilizer recorded highest consumption
in Nellore district with a mean consumption of 66435 tonnes.
In Prakasam district total cropped area, gross irrigated area and rainfed area recorded
negative growth rate but in Nellore district total cropped area and rainfed area recorded
negative growth rate and gross irrigated area showed positive growth rate.
Out of the three independent variables viz., total cropped area, gross irrigated area and
rainfed area that were included in the regression model, in maximum cases gross irrigated area
significantly affected the fertilizer consumption except in Nellore district where total rainfed area
had significantly affected the Phosphate fertilizer consumption.
