New Delhi: The Department of Science and Technology is trying to calculate the total crop output in the country using remote sensing technology over the next six months. The DST has worked out an algorithm using various inputs like rainfall, moisture content in soil and plant properties to arrive at crop estimates. If the project is successful, the data will available much faster than the present methodology being used by the National Sample Survey Organisation (NSSO). The crop output estimates are arrived at by the crop cutting experiments of sample areas by the NSSO, with inputs from Department of Agriculture. The pilot project, carried out for Haryana, for crops like mustard, wheat, cotton and paddy, has been successful.
Applying the newly developed model, the DST arrived at the production estimates for Haryana for 2004-05, 2005-06, 2006-07 and compared it with the NSSO data for validation. The data for 2005-06, which had a variation with the NSSO crop production data, happened to be closer to procurement data of the Haryana. Incidentally, according to DST, the production in Haryana in 2005-06 was lower due to excess heat. Now, the StateGovernment has asked weekly reports from the DST that can show soil moisture content, rainfall, sowing and the extent of green-cover for each village.
