“…This technology can be implemented on lines, new high-yielding, or local rice varieties with the Sub-1 gene. Dash et al [37] reported that the recommendation for cultivation technology for the Swarna-Sub-1 and CR 1009 Sub-1 varieties is application of N: P: K fertilizer at a dose of 80-40-40 kg ha -1 , setting the seedlings transplanting age to 30 days after planting, and application of N fertilizer at a rate of 20 kg ha -1 at seven days after receding of floodwater. The implementation of this cultivation technology can recover the impact of immersion so that the yield of the Swarna-Sub-1 variety reaches 5.523 t ha -1 .…”

Swampland is one of the potential agroecosystems of rice production in Indonesia, but it is classified as marginal in terms of unpredictable inundation, primarily due to global climate change impact. Submergence-resistant variety’s high-yielding and efficient input are one of the efforts to overcome these constraints. The review aims to explore information on the availability and potentiality of immersion-resistant varieties, the efficiency of cultivation technology, and the availability and potentiality of local rice as a source of genes in creating immersion-resistant varieties. The review method is a reference study of different research results. The review results show that five varieties of swampland rice are mainly assembled to withstand immersion in all vegetative phases, namely for six days (Inpara 3) and fourteen days (Inpara 4-5, Inpari 29-30). Based on the Relative Agronomic Efficiency (RAE) parameter, cultivation technology is available. However, information on the research results and its implementation on these five varieties and other high-yielding rice varieties in the swampland is still limited. Sixteen local accessions of inundation tolerance have been identified. Further research is needed on different varieties of immersion resistance, RAE parameters-based cultivation technology, and new immersion-resistant varieties using available local varietal gene donors. This way the availability of effective technology and its dissemination efforts will have the opportunity to be adopted by the stakeholders, thus increasing their productivity and income.

“…These results have been confirmed by multiple tests of submergence tolerance carried out in farmers' fields and greenhouses [7], and the same result has been observed in floodprone places [8] for the Swarna sub 1 variety. According to [9], introducing this variety will significantly increase rice yield in low-lying places.…”

The study was conducted in the villages of Rayapuram and Keezhapattu in Tamil Nadu, as part of the National Innovation on Climate Resilient Agriculture (NICRA) project in the Needamangalam district of Thiruvarur from 2015 to 2018. These villages frequently experienced floods, particularly impacting the rabi season's crop growth and maturity. The monsoon season (September to December) contributed to about 71% of the total rainfall. A comparative analysis was carried out to assess the economic performance of the flood-resistant paddy variety CR 1009 sub 1 in contrast to the commonly grown CR 1009. Traditionally, farmers in Rayapuram and Keezhapattu favored CR 1009 due to its high market value during the monsoon period. However, they faced low income due to flooding in the rabi season. To address this challenge, scientists from KVK, Thiruvarur, recommended the flood-tolerant paddy variety CR 1009 sub 1 for cultivation during the rabi season under the "National Innovations in Climate Resilient Agriculture (NICRA)" project. Specific climate-resilient technologies, including flood-tolerant paddy variety "CR 1009 sub 1" and a high-yield, long-duration rice variety, were tested and demonstrated in the project villages to ensure rice production despite climatic variations leading to floods. It was crucial to assess how these varieties responded to climate vulnerabilities and how receptive farmers were to adopting them. Calculations were made to compare paddy productivity and economic returns under the improved technology with the traditional practices of farmers. The results indicated that the "CR 1009 sub 1" variety yielded higher harvests compared to the farmers' practices in the years 2015–16, 2016–17, and 2017–18, with increases of 12.60%, 11.69%, and 12.95% respectively. Furthermore, using improved technologies for paddy cultivation generated higher net returns of Rs. 57233, 60768, and 57728 per hectare in 2015–16, 2016–17, and 2017–18, respectively, in contrast to the farmers' practices (which yielded Rs. 49147, 50295, and 46266 per hectare in the same years). In comparison to the farmers' practices (with an average net return of Rs. 48569 per hectare and a benefit-cost ratio of 2.37), the demonstration fields showed an average net return of Rs. 58576 per hectare and a benefit-cost ratio of 2.56.

“…Furthermore, a wide scale adoption of SS1, prior to floods would have resulted in an approximate increase in rice production by 26% [21]. Apart from flood tolerance, the SS1 seeds also reduce the risk of yield loss during the normal growing period i.e., when there is no flood impact [20,22,23]. Overall, the development of submergence-tolerant varieties allows farming communities to become more resilient to existing and growing flooding risks [24].…”

Rice is the most important food crop. With the largest rain-fed lowland area in the world, flooding is considered as the most important abiotic stress to rice production in India. With climate change, it is expected that the frequency and severity of the floods will increase over the years. These changes will have a severe impact on the rain-fed agriculture production and livelihoods of millions of farmers in the flood affected region. There are numerous flood risk adaptation and mitigation options available for rain-fed agriculture in India. Procuring, maintaining and distributing the newly developed submergence-tolerant rice variety called Swarna-Sub1 could play an important role in minimizing the effect of flood on rice production. This paper assesses the quantity and cost of a flood-tolerant rice seed variety- Swarna-Sub1, that would be required during the main cropping season of rice i.e., kharif at a district level for 17 major Indian states. The need for SS1 seeds for rice production was assessed by developing a geospatial framework using remote sensing to map the suitability of SS1, to help stakeholders prepare better in managing the flood risks. Results indicate that districts of Bihar, West Bengal and Uttar Pradesh will require the highest amount of SS1 seeds for flood adaptation strategies. The total estimated seed requirement for these 17 states would cost around 370 crores INR, less than 0.01 percent of Indian central government’s budget allocation for agriculture sector.
