The Tamil Nadu Agricultural University (TNAU) Agricultural Engineering College and Research Institute has taken up a research on producing paddy using sprinkler irrigation.
Research aims at ensuring maximum utilization of water by ascertaining the moisture of the soil periodically. Irrigation water is wasted when used excessively. While, sprinkler irrigation, with its rotation system, ensures economic and effective use, says K Ramaswamy, Dean.
He further added that the institute had taken up the experiment in response to the Prime Minister Narendra Modi’s call to adopt water conservation techniques. Two varieties – ‘Anna R 4’ and ‘ADT 49’ had been raised in the past and CR 1009 paddy is being raised at the farm.
“The moisture of the soil is closely monitored and the field is irrigated once in three days,” he said explaining the technical analysis for ascertaining the moisture level of the soil.
“If the field is too dry, the roots will need more energy for respiration,” he said. The field is never allowed to go dry which ensures regular irrigation for paddy.
The sprinkler is not used during pollination period of two hours between 10 a.m. and noon as the water from sprinkler would gush out with greater pressure disturbing the pollination process.
