Description The present study entitled “Study of Fertilizer Consumption Pattern in
North Coastal Districts of Andhra Pradesh” has been attempted to identify the
trends in fertilizer consumption. The reference period of study was from 1979-80
to 2003-2004 and the study was carried out for the North Coastal region of Andhra
Pradesh comprising of Srikakulam, Vizianagaram, and Visakhapatnam districts.
Trends in fertilizer consumption, total cropped area, net irrigated area,
rainfed area were identified by computing compound growth rates. Trends in
Fertilizer consumption for these three North Coastal districts and Andhra Pradesh
state as whole were studied. The determinants of fertilizer consumption were
identified by multiple linear regression using non-price factors like total cropped
area, rainfed area, net irrigated area and rainfall. An attempt had also been made to
assess the rainfall pattern of these three North Coastal districts using cluster
analysis.
The study revealed that the N, P, K and NPK total fertilizer consumptions
marked a significant increasing trend for the North Coastal districts and state as a
whole. Potash consumption recorded highest compound growth rate in all the
districts. Almost all the three North Coastal districts exhibited positive trend but
non-significant incase in total cropped area, net irrigated area and rainfed area.
The rainfall pattern was identified for South-West and North-East monsoon
periods using the cluster analysis and it revealed the most probable and
representative pattern of rainfall in each district. It is also revealed that the total
cropped area that determined fertilizer consumption mostly, followed by Rainfall
among non-price factors that were included in the regression model.
The compound growth rates of Nitrogen, Phosphate, Potash and Total
fertilizer consumption of Srikakulam district were 3.99, 8.19, 22.10 and 5.05 per
cent respectively. Potash consumption was recorded the highest growth rate over
the years in the Srikakulam district. It was revealed the change in consumption
levels over the years. The compound growth rates of Nitrogen, Phosphate, Potash
and Total fertilizer of Vizianagaram district were 5.80, 6.65, 20.38 and 6.31 per
cent respectively. The compound growth rates of Visakhapatnam district were
6.45, 4.44, 18.05 and 6.59 per cent respectively. The compound growth rates of
Nitrogen, Phosphate, Potash and Total fertilizer for entire Andhra Pradesh state
were 5.05, 6.06, 6.46 and 5.45 per cent respectively.
The cluster analysis revealed the season wise rainfall pattern for twenty five
years of rainfall data for the all the three districts. The average rainfall for the most
probable clusters was obtained. The rainfall pattern in Srikakulam district was
identified by cluster analysis and thecluster-1 with 0.44 probability referred as
most probable pattern of rainfall during the South-West monsoon and the cluster-1
with 0.56 probability referred as most probable pattern of rainfall during North-
East monsoon. In Vizianagaram district the cluster-2 with 0.48 probability referred
as most probable pattern of rainfall during South-West monsoon and the cluster-2
with 0.44 probability referred as most probable pattern of rainfall pattern during
North-East monsoon. In Visakhapatnam district the cluster-1 with 0.68 probability
referred as most probable and representative pattern of rainfall during South-West
monsoon and the cluster-2 with 0.44 probability referred as most probable pattern
of rainfall during North-East monsoon.
Out of the four independent variables viz., total cropped area, net irrigated
area, rainfed area and rainfall that were included in the regression model, in most
of the cases for all the three districts only the total cropped area turned out to be
significantly affecting the fertilizer consumption. However, in Vizianagaram
district the rainfall turned out to be significant in determining the Nitrogen
consumption during sub period-2 and the total fertilizer consumption during
subperiod-2.
