Assessing area, production and return with rice varieties of NRRI, Cuttack

Abstract

The ICAR-National Rice Research Institute (NRRI), Cuttack in Odisha develops varieties and agro-technologies for enhancing and sustaining rice production. The Institute so far has released 133 high-yielding varieties of rice for various ecosystems. Some of the varieties have been very popular among the farmers and even became ruling varieties in some states. However, there are no reports on the area covered by NRRI varieties and its impact on incremental gain in farm income. In the present study, area covered by NRRI varieties in the country during 2017-18 was estimated based on the amount of quality seeds provided to the farmers through various ways: breeder seed indent to the DAC; breeder seed and truthfully-labeled seed supplied by the NRRI farm; participatory seed production by NRRI; seed distributed in various programmes and projects of the Institute; front-line demonstrations and on-farm testing; seed of NRRI varieties supplied by the private entrepreneurs and disseminated from farmers to farmers etc. A validation exercise was conducted to cross-check the estimated areas under NRRI varieties. The analysis showed that currently NRRI varieties cover about 8.0 million ha (Mha) i.e., 18% of rice area of the country. West Bengal has the largest area of 2.26 Mha, followed by Odisha with 2.18 Mha. Total production of rice with NRRI varieties is 27.80 million tons (Mt) with the value of Rs.48,643 crores per annum. Further, incremental production and income with NRRI varieties considering 5% more than the existing popular varieties is estimated to be 1.39 Mt and Rs.2,432 crores per annum, respectively. Over the years, indents of breeder seed (BS) of NRRI varieties have increased considerably indicating growing popularities of NRRI varieties among the farmers in different states.

Marker‐trait association analysis for gall midge (Orseolia oryzae) resistance in a diverse rice population

“…Rice, being a staple cereal, aids in feeding nearly 60% of the world's population (Joshi et al, 2018). Rice is also widely grown in India, with 117.47 million tonnes produced, accounting for 40% of total grain production (Pathak et al, 2020). However, accounting for the losses because of biotic and abiotic stresses, India continues to trail behind China, Indonesia, and Vietnam in terms of average rice productivity (2.6 t/ha) (Pathak et al, 2020).…”

Among the biotic constraints causing a loss in rice production, insect herbivores play an indispensable role in lowering the yield level (Jena et al, 2018).…”

Mutation resource of Samba Mahsuri revealed the presence of high extent of variations among key traits for rice improvement

“…Rice is the staple food for almost 56% of the world’s population and it is the source of 20% of the world’s dietary energy supply. Global rice consumption is projected to increase from 500 million to around 750 million tons by 2050 [ 1 ]. Hence, rice production has to be enhanced (50% projected growth) to match the increased requirements of the future.…”

Innovative Technology Added Value in Reducing Rice Yield Gap in Tidal Land

“…Of course, the tidal agro ecosystem with its constraints and problems needs to be minimized so that the specified output can be achieved. Therefore, to protect the environment while improving rice productivity to meet the ever-growing demand, careful management of rice ecosystem functions, the use of technology, infrastructure, and policies must be updated and embraced [8].…”
