To increase rice yield in areas with high soil salinity in Haryana, Uttar Pradesh and Puducherry, scientists at Central Soil Salinity Research Institute (CSSRI), Karnal, and its Regional Research Station at Lucknow have developed and released three salt-tolerant varieties — CSR-46, CSR-56 and CSR-60.

CSR-56 and CSR-60 have been released under the long bold grains and long slender grains category, respectively.

These were released by the Central Sub-Committee on Crop Standards last month for the sodic soil of the rice growing regions in these three states. Scientists claim these are high-yielding varieties. During trial, these varieties showed moderate resistance to pest and diseases, such as leaf blast, neck blast, brown spot, stem borer, leaf folder, case worm, blue beetle and white-backed planthopper.

Giving details, Dr PC Sharma, Director, CSSRI, said during the trial, the CSR-46 variety gave 10 per cent higher grain yield in comparison to the previous salt-tolerant variety CSR-36 for UP areas. Its production was 36 per cent higher in comparison to UP’s NDRK-50035 variety. He said it matured, on an average, in 130-135 days, and gave 65 quintal per hectare under normal soil, while it gave 40 quintal per hectare on salt-affected soil. About CSR-56, the Director said it was released for rice growing regions under salt-affected soils in Haryana and UP. It gave 18 per cent higher grain yield in comparison to previous salt-tolerant variety CSR-36 and 86 per cent high yielding in comparison to high-yielding variety Jaya.

“It matures in 120-125 days and gives yield of 70 quintal per hectare under normal soil and 43 quintal per hectare under the sodic soil,” he said.

The Director said the CSR-60 variety had been developed for the sodic soils of the rice growing regions of Uttar Pradesh and Puducherry.
