Description |
The present study entitled “Study of Fertilizer Consumption Pattern in relation to Rainfall in the Southern part of Telangana region of Andhra Pradesh” had been attempted to identify the trends in fertilizer consumption and its relation to rainfall distribution. The reference period of study was from 1979-80 to 2008-09 and the study was carried out for the three districts in Southern part of Telangana region comprising of Mahabubnagar, Medak and Nalgonda districts. Trends in fertilizer consumption were identified by compound growth rates. Trends in fertilizer consumption for these three districts as whole were studied. An attempt had also been made to assess the fertilizer consumption pattern in relation to rainfall pattern identified by correlation values by using cluster analysis. The study revealed that the N, P, K and total NPK fertilizer consumptions marked a significant increasing trend for the three districts. Potash consumption recorded highest compound growth rate in Medak and Nalgonda district. In Mahabubnagar district Phosphate consumption recorded highest compound growth rate and almost all the three districts exhibited positive trend. The fertilizer consumption pattern and rainfall pattern were identified for South-West monsoon, North-East monsoon and Total year using the cluster analysis and it revealed the season wise most probable and representative pattern of rainfall and fertilizer consumption in each district. The compound growth rates of Nitrogen, Phosphate, Potash and Total fertilizer consumption of Mahabubnagar district were 4.278, 5.332, 4.138 and 4.461 percent respectively. Phosphate consumption was recorded the highest growth rate over the years in the Mahabubnagar district. It was revealed the change in consumption levels over the years. The compound growth rates of Nitrogen, Phosphate, Potash and Total fertilizer consumption of Medak district were 5.675, 6.162, 9.395 and 6.060 per cent respectively. The compound growth rates of Nalgonda district were 7.123, 7.591, 9.211 and 7.412 per cent respectively. Potash consumption recorded highest compound growth rate in Medak and Nalgonda district. The cluster analysis revealed the season wise fertilizer consumption and rainfall pattern for thirty years of data for all the three districts. The average fertilizer consumption and rainfall for the most probable clusters were obtained. The fertilizer consumption pattern in relation to rainfall in three districts was identified by cluster analysis and correlation. In Mahabubnagar district, the rainfall pattern of two seasons and total for the year and the fertilizer consumption pattern positively correlated with rainfall pattern which was not significantly correlated. In Medak district, South-West monsoon and North-East monsoon fertilizer consumption negatively correlated with rainfall and was not significantly correlated. In the case of total year relationship between the fertilizer consumption and rainfall pattern was positively correlated which was not significantly correlated. Fertilizer consumption pattern was found to be positively correlated with rainfall pattern and the fertilizer consumption was not significantly correlated with rain fall pattern in two seasons in Nalgonda district. In the case of total year, relationship between the fertilizer consumption and rainfall pattern is negatively correlated which was not significantly correlated. |
