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. |
