A new research plan on cultivation of sugarcane using drip irrigation technique has taken up by Tamil Nadu Agricultural University’s Sugarcane Research Station at Sirugamani for achieving higher yield with good sugar content. Drip irrigation is a form of irrigation that saves water and fertilizer by allowing water to drip slowly to the roots of many different plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters.The research, being carried on an area of two acres using the ‘TNAU (S) Si 8’ variety, focuses on maximum utilisation of available water. It would also help to educate the farmers on ways and means for economic use of fertilizers. More importantly, the length of the cane, the length of the nodes and inter nodes also increase appreciably, quoted by R. Chandrasekaran, Professor and Head of the Station.
He states that water efficiency would be about 30 to 40 per cent over the conventional irrigation practices. Since drip irrigation is also used for supplying fertilizer, the entire quantum of fertilizer is fully utilised for cane growth. “In the conventional method, much of the fertilizer is lost into the earth,” he said.
Spacing and Mechanisation
The major advantage of drip irrigation ensures adequate spacing which, in turn prevents the growth of weeds in the sugarcane field. Even in case of weed growth, they can be cleared mechanically. Further, the wide space available would facilitate mechanised harvest process. Many sugarcane farmers have been visiting the Kendra for an exposure to the technique.

So much of attention is given by governments on drip irrigation which aims at improving the ways of cultivation and utilizing economy resources properly. Some of the Pros/Advantages which drip irrigation brings to help farmers and to make the best possible use of scarce resources are as follows:-
- Weeds can not absorb water as no water is available for them.
- Yield of crops are maximum.
- Fertilizers can be used with high efficiency.
- Weed are grown in less number.
- Operational cost is low.
- Soil erosion is not taken place.
- Soil infiltration capacity is increased.
- Fertilizers and ground water is not mixed.
As every concept has its own positive and negative aspects it should be considered that what are the methods/things which could harm the cultivation of sugarcane or any other crop. If not properly used certain mishappenings can take place, keeping in mind the Cons/Disadvantages of drip irrigation are as follows:-
- Problems in moisture distribution.
- Salinity problem.
- Germination problem.
- High skills are required.
