Tamil Nadu Agricultural University launches Irrigation Water Calculator

Irrigation Water Calculator was launched jointly by TNAU (Tamil Nadu Agricultural University) and IWMI (International Water Management Institute)-TATA Policy Research Program(IWMI TATA) here on Thursday.

The calculator has been developed for the first time in the country by S.Raman, Water Management scientist and consultant to IWMI.

After launching the calculator, TNAU Vice Chancellor P.Murugesa Boopathi pointed out that it can calculate the water requirement specific to each crop and location. He said that water available for agriculture was expected to decrease from 85 percent to 73 percent by 2025 due to ground water over exploitation and increasing NEED for industrial use and human consumption.

S.Raman, the inventor of the calculator, explained that the irrigation water calculator was a micro-processor-based platform for calculation of water requirements of all types of crops grown in different climatic conditions.

According to him, the calculator which works based on climatological approach estimates the water requirement for different stages of crop growth taking into account the drip irrigation system efficiency. It operates on a 9 V battery and has option for rechargeable battery. It has advantages like energy saving and additional 30 to 40 percent water savings in the existing drip irrigation use.

Sources said that the calculator is likely to be provided to select villages free of cost. Though the price of the calculator has not been officially fixed, it is expected to cost around Rs.1000.
