Rice output rising repeatedly, because of 2 high-yield varieties from ICAR


“If the prediction of IMD comes true, farmers will realise the efficacy of CR Dhan 801 and this may assist develop the range,” Singh mentioned. A minimum of 20,000 quintal of seeds (ample for 60,000 hectare) of this selection could also be accessible throughout kharif 2021 season in japanese UP, he added.

Even because the nation has been witnessing flood and drought in some components nearly yearly, the rice manufacturing has been repeatedly rising — reaching a report 120.32 million tonne in 2020-21 crop yr (July-June) – because of the agriculture scientists’ fixed endeavour to develop newer varieties with greater yield. Two such varieties – CR Dhan 801 and CR Dhan 802, developed by Nationwide Rice Analysis Institute (NRRI) having distinctive traits of each drought- and flood-tolerant — are more likely to be boon for the farmers within the calamity-prone japanese area because of its acceptance by farmers.

Because the India Meteorological Division has predicted decrease than regular monsoon rainfall throughout ensuing season in japanese area of India, these two rice varieties might assist farmers tide over any drought-like situation. Seasonal rainfall this yr may be 98% of LPA with a mannequin error of +/-5%, M Rajeevan, secretary at ministry of earth sciences on April 16 had mentioned, including the precipitation could possibly be regular throughout the nation, barring Odisha, Jharkhand, Bihar, Assam and japanese Uttar Pradesh.

As much as 10,000 hectare was lined below these two varieties, largely below CR Dhan 801 final kharif season, from about 5,000 hectare in 2019, for multiplication of seeds. Solely in japanese Uttar Pradesh, CR Dhan 801 selection was planted in about 700 hectare, mentioned Ram Kathin Singh, govt director of Lucknow-based Nand Academic Basis for Rural Improvement (NEFORD). Singh, a retired professor of genetics and concerned within the distribution of those seeds, additionally mentioned that the typical yield was round 6-7 tonne per hectare the place his company was intently monitored the cultivation.

“If the prediction of IMD comes true, farmers will realise the efficacy of CR Dhan 801 and this may assist develop the range,” Singh mentioned. A minimum of 20,000 quintal of seeds (ample for 60,000 hectare) of this selection could also be accessible throughout kharif 2021 season in japanese UP, he added.

Launched for industrial cultivation final yr, the CR Dhan 801 is supposed for Andhra Pradesh, Telangana, Odisha, West Bengal and Uttar Pradesh, which have 33-98% of paddy space below irrigation. This selection is in reality an enchancment over the favored Swarna Sub1 selection (which is flood-tolerant), in keeping with S Okay Pradhan, principal scientist at NRRI. Three genes of drought-tolerant traits from different varieties are added in CR Dhan 801 and two such genes in CR Dhan 802, which is supposed for Bihar and Madhya Pradesh (34-65% paddy space irrigated).

Pradhan additionally mentioned that the present common yield in these two new varieties is 6 tonne/hectare which could be improved as much as 8 tonne below good practices. Throughout flooding, even when the crop is submerged for 14 days, the yield will fall most 30%, relying on torbidity in water. In case of a drought, the yield will most drop by a half. “We’re engaged on varieties that may stand up to flooding upto 3 weeeks,” he mentioned.

Each CR Dhan 801 and CR Dhan 802, weakly photosensitive with common maturity of 140-145 days, are immune to stem borer (each lifeless coronary heart and white ear heads), leaf folder and case worm whereas reasonably immune to bacterial blight and rice tungro virus. However, CR Dhan 802 is moreover immune to plant hopper, too.

“These varieties, if promoted by the Centre and states collectively, the japanese area can present sustainable manufacturing of extra requirement of rice in case the federal government decides to shift non-basmati cultivation from Punjab, Haryana and Uttar Pradesh,” mentioned an knowledgeable. Greater than 60% of water accessible for agriculture use within the nation is diverted in the direction of irrigating two water guzzler crops, rice and sugarcane, having a share of simply 24% in gross cropped space.

The federal government’s efforts to incentivise Punjab and Haryana farmers to shift from water-guzzler non-basmati rice to different crops like maize and cotton haven’t been very profitable up to now within the absence of sturdy, remunerative and assured procurement system for these crops.
Based on Ashok Gulati, a former chairman of the Fee for Agricultural Prices and Costs (CACP), farmers in these two states use a staggering 5,000 litres of water to supply only one kilogram of rice.

All India rice yield has elevated from 2.18 tonne/hectare in 2008-09 to 2.58 tonne/hectare in 2017-18. Nonetheless, in main producing states like Punjab the yield is as excessive as 4.37 tonne. Even throughout the state, there’s a huge disparity in rice yield because of varied components. For example, the state common of yield is 1.8 tonne (in 2017-18) in Odisha whereas in a number of the irrigated western districts it’s as excessive as 6-7 tonne.
