In order to know the technological impact of the Drip cum fertigation, time series analysis has been conducted. The result shows that the following

It could be drawn from the Time Series Analysis that the area under sugarcane was cultivated using conventional methods before the year 2000. The modern technology on drip cum fertigation was introduced during the period 2000 to 2001 through awareness campaign then the area was only 7.20 ac but the yield was 118.18 t/ha. It is due to the drip cum fertigation system which increase the water and nutrient use efficiency since the application is very closer to the rhizosphere of the crop. During the year 2001-2002, the technology was popularized through 'model farm approach' the areas also mushrooming to 52.00 acres under this technology. Similarly, Farmer to farmer approach was followed in the year 2003 then the area under drip was increased to 77.17 acre. In addition to the afore mentioned approaches, the farmers were motivated with the support of the officials of the sugar factories by emphasizing the opportunities of the drip irrigation there by the area had been increased to 337.12 ac during the period 2003-2004. Further, the KVK took efforts intensively to increase the area under drip cum fertigation through Integrated Participatory Approach and by organizing awareness campaign, model farms, training programmes along with the line departments. In order to make them to learn firsthand information field visits were organized for the trainees.

The critical analysis on yield particulars inferred that the yield increase of drip cum fertigation over conventional method was 23% per hectare. The drought is the crucial factor often intervening the yield parameters and led to yield reduction. It could be effectively managed by the drip irrigation system. Unless this drip irrigation system, the production of sugarcane will face a critical issues.

Due to the technical feasibility, economical variability and social acceptability of the technology, the State Government of Tamil Nadu welcomed this technology and advised the scientists to popularize the technology in 2.00 lakhs hectare area in Tamil Nadu. However approval was already given to popularize the technology in 375 hectares in the districts viz., Sivagangai, Pudukkottai, Thanjavur, Kancheepuram and Coimbatore so as to increase the production and productivity of the sugarcane crop.
