NIGER: Rapport de formation des producteurs de riz en hors amenagement sur le Systeme de Riziculture Intensive (SRI)

NIGER: Rapport de formation des producteurs de riz en hors amenagement sur le Systeme de Riziculture Intensive (SRI) | SRI Global News: Aug - Oct. 2024   *SRI-Rice -- System of Rice Intensification | Scoop.it

Dans le cadre de la mise à l’échelle de l’approche SRI (Système de Riziculture Intensive) par le PPAAO au Niger, une formation pratique des producteurs de riz hors-aménagement s’est tenue du 13 au 14 août 2018 sur le périmètre rizicole de Sébéri. L’atelier a regroupé vingt-quatre participants dont les CDA et les producteurs de régions de Zinder Tahoua,  Tillabéri et Dosso. L’objectif principal était de former des champions SRI capables à leur tour de disséminer l’information à d’autres producteurs de riz de leur zone.

SRI-Rice's insight:

English summary: As part of the scaling up of the SRI approach that continues to be used by the West Africa Agricultural Productivity Program (WAAPP) in Niger, practical training for rice farmers was held from August 13-14, 2018, in the Sébéri irrigation scheme of Niger. Participants came from regions of Zinder, Tahoua, Tillabéri and Dosso. The main objectives were to train SRI champions who in turn could disseminate information to other rice producers in their area and to increase the number of specialized NIS producers who could be used as FFS facilitators to popularize this  ecological approach to producing rice.

MANIPUR, INDIA: System of Rice Intensification - A Way of Reducing GHGs

MANIPUR, INDIA: System of Rice Intensification - A Way of Reducing GHGs | SRI Global News: Aug - Oct. 2024   *SRI-Rice -- System of Rice Intensification | Scoop.it

Climate change and climate variability create hurdles for food security and agriculture- based livelihoods, and acts as an obstacle to the economic growth of the people of Manipur, India.

The Directorate of Environment has introduced the System of Rice Intensification (SRI) to reduce GHG emissions and improve agricultural productivity in Phayeng village where a project to transform the village to a carbon-positive eco model village is in progress. Twenty-one farmers covering about 12 hectares of land were selected based on their interest and field conditions for a pilot study of SRI. Recent changes in the climate are affecting the Phayeng ecosystem services in terms of agricultural sectors and food insecurities.

 

A high potential is seen in SRI to help secure livelihoods and to enhance resilience to expected adverse impacts of climate change. SRI can be applied with both irrigated and rain-fed rice systems. The most vulnerable people and vulnerable economic sectors like agriculture will be given attention on priority basis.

TAMIL NADU, INDIA: Rhizosphere Bacterial Diversity and Soil Biological Attributes of Rice in Different Phenological Stages and Wetland Cultivation Methods

 This study assesses the impact of three cultivation methods (wetland, SRI, and direct seeding) on the biochemical properties and bacterial communities within the rice rhizosphere across three key growth stages: tillering, flowering, and maturity. The results deepened our understanding of how different cultivation practices influence plant-microbe interactions and their implications for overall rice productivity and soil health. Soil organic carbon (SOC), microbial biomass carbon (MBC), dehydrogenase, substrate-induced respiration (SIR), and metabolic quotient (MQ) were assessed along with high-throughput 16S rRNA sequencing of rice rhizosphere soils.

 

The rice rhizosphere soil under the SRI registered the highest SOC, MBC, and dehydrogenase followed by wetland and least in direct seeded aerobic cultivation. Cultivation methods caused notable shifts in the abundance of Proteobacteria, Bacteroidetes, and Chloroflexi, while crop growth stages affected the abundance of Proteobacteria, Actinobacteria, Cyanobacteria, Firmicutes, Chloroflexi, and Bacteroidetes. Based on these results, the SRI method brings higher diversification to the rhizosphere bacteriobiota, as well as greater incorporation of carbon into the soil and increased dehydrogenase activity compared to the wetland and aerobic rice.

TAMIL NADU, INDIA: Assessing the Impact of Climate Change on Methane Emissions from Rice Production Systems in Southern India

TAMIL NADU, INDIA: Assessing the Impact of Climate Change on Methane Emissions from Rice Production Systems in Southern India | SRI Global News: Aug - Oct. 2024   *SRI-Rice -- System of Rice Intensification | Scoop.it

The impact of climate change on methane (CH4) emissions from rice production  in the Coimbatore region of Tamil Nadu was studied utilizing the closed-chamber method for gas collection and gas chromatography analysis. This study identified differences in CH4 emissions between conventional cultivation methods and the system of rice intensification (SRI). Experimental data were subsequently used to guide parametrization and validation of the DeNitrification–DeComposition (DNDC) model.

 

The validated model was then used to develop future CH4 emissions projections under various shared socio-economic pathways for the mid- (2021–2050) and late (2051–2080) century. The analysis revealed a potential increase in CH4 emissions for the simulated scenarios, which was dependent on specific soil and irrigation management practices. Conventional cultivation produced the highest CH4 emissions.  The findings underscored an urgency to develop climate-smart location-specific mitigation strategies focused on simultaneously improving current water and nutrient management practices. This research also highlighted the critical interaction that exists between agricultural practices and climate change, and emphasized the need to implement adaptive crop management strategies that can sustain productivity and mitigate the environmental impacts of rice-based systems in southern India.

ANGOLA: SRI Methods are Tested in Angola for the First Time

ANGOLA: SRI Methods are Tested in Angola for the First Time | SRI Global News: Aug - Oct. 2024   *SRI-Rice -- System of Rice Intensification | Scoop.it

Rice consumption in Angola, like in many other African nations, is rising due to shifts in eating habits and population growth. The surge in consumption combined with low domestic production and productivity has led to a consistent rise in rice imports. In 2021 the State Treasury of Angola spent over US$260 million on rice imports.

 

During a February 2024 African Paddy Rice Greenhouse Gas Mitigation workshop, Eng. Carlos Francisco Canza,  Angola's focal point within the Coalition for African Rice Development (CARD) from the Rural Extension Department at the Ministry of Agriculture and Forestry, learned about SRI. Elielda Lopes Fernandes, the Tony Blair Institute (TBI) Manager for Food and Agriculture in Angola,  was also interested in SRI, and with SRI-2030 knowledge materials, they transplanted the rice seedlings in early July 2024 following SRI principles, marking the first known experimentation of SRI methods in Angola.

Green manuring–system of rice intensification (SRI)–blackgram (rice fallow pulses) cropping system is novel, and appears to be a sustainable approach, combining innovative farming techniques to optimize yields, improve soil health, and minimize environmental impacts. Field demonstrations were conducted on a farmer's field through the National Pulses Research Centre, Vamban, Pudukkottai, Tamil Nadu, within the kharif rabi and summer seasons of 2019–20. The demonstration was conducted in 50 hectares with 92 locations of Ponnaniyar sub-basin.

 

The improved practice of SRI recorded higher plant height and other yield attributes, including yields from 7580 to 9400 kg ha−1. Concurrently, within the IPT framework for the GM–SRI–Rice fallow pulses cropping system, the yields for Rice fallow Blackgram were 590 to 730 kg ha−1. A remarkable 39.9 percent enhancement in system productivity through the adoption of IPT practicesas well as significantly higher water productivity, The green manure–system of rice intensification–rice fallow pulses crop sequences emerged as the more productive and sustainable option, displaying the potential to enhance soil productivity and fertility status compared to conventional rice–blackgram/groundnut cropping sequences. These systems present promising alternatives for farmers Tamil Nadu's Ponnaniyar sub-basin.

Exploring the Impact of Alternate Wetting and Drying and the System of Rice Intensification on Greenhouse Gas Emissions: A Review of Rice Cultivation Practices

Exploring the Impact of Alternate Wetting and Drying and the System of Rice Intensification on Greenhouse Gas Emissions: A Review of Rice Cultivation Practices | SRI Global News: Aug - Oct. 2024   *SRI-Rice -- System of Rice Intensification | Scoop.it

An article in Agronomy shows that there need not be a trade-off between food security and climate change mitigation. A review of field studies found that SRI is associated with both reduced GHG emissions and higher yield compared with conventional flooded rice farming. The authors found that the mean reduction in emissions per kilogram of rice produced was 48% when SRI is compared with conventional practices. Yield benefits of SRI compounded the already significant reduction in emissions associated with alternate wetting and drying (AWD). The authors recommend that farmers be encouraged to adopt SRI practices given the dual benefits for food security and climate change mitigation. They also cited other benefits of SRI, and call for more research into the potentially even more significant benefits of soil carbon sequestration with SRI.

LIBERIA: SRI Methods have Positive Impact in the LIFE Project in Crayton Town, Grand Bassa County

LIBERIA: SRI Methods have Positive Impact in the LIFE Project in Crayton Town, Grand Bassa County | SRI Global News: Aug - Oct. 2024   *SRI-Rice -- System of Rice Intensification | Scoop.it

The Community of Hope Agriculture Project (CHAP) is implementing Climate Smart Agriculture under the Livelihood Innovation Food Security Entrepreneurship (LIFE) Project with funding from Irish Aid through Concern Worldwide Liberia. The project, which began in Grand Bassa, Liberia, during 2023 and extended to Rivercess in February 2024, is currently working with 25 smallholder farmers per community, which comprises a total of 214 smallholder farmers who are being introduced to the System of Rice Intensification (SRI) for rice cultivation.


Since the introduction of the SRI in Grand Bassa County, farmer groups like the one in Crayton Estate, have been able to grow rice twice in a year with less external inputs. The resulting SRI adoption has proven sustainable for farming thus far and is achieving high yields. In addition to SRI methods for production, CHAP has created a market for the SRI farmers’ out-grower scheme across the country in support of the “I love Liberian rice” domestic rice production in keeping with the Ministry of Agriculture’s National Agriculture Development Plan (NADP), which includes cultivation of 50,000 ha of lowland rice across the country from 2023 to 2030.

INDIA: Ecological Weed Management and Square Planting Influenced the Weed Management, and Crop Productivity in Direct-Seeded Rice

INDIA: Ecological Weed Management and Square Planting Influenced the Weed Management, and Crop Productivity in Direct-Seeded Rice | SRI Global News: Aug - Oct. 2024   *SRI-Rice -- System of Rice Intensification | Scoop.it

Herbicide use may pose a risk of environmental pollution or evolution of resistant weeds. As a result, an experiment was carried out to assess the influence of different non-chemical weed management tactics (one hoeing (HH) at 12 DAS followed by (fb) one hand weeding at 30 DAS, one HH at 12 DAS fb Sesbania co-culture and its mulching, one HH at 12 DAS fb rice straw mulching @ 4t ha−1, one HH at 12 DAS fb rice straw mulching @ 6 t ha−1) on weed control, crop growth and yield, and economic returns in direct-seeded rice (DSR). 

 

Zero-till seed drill-sown crop (PN) had the lowest weed density at 25 days after sowing (DAS), while square planting geometry (PS) had the lowest weed density at 60 DAS. PS also resulted in a lower weed management index (WMI), agronomic management index (AMI), and integrated weed management index (IWMI), as well as higher growth attributes, grain yield (4.19 t ha–1), and net return (620.98 US$ ha–1). In the case of weed management treatments, one HH at 12 DAS fb Sesbania co-culture and its mulching had the lowest weed density  at 25 DAS. However, one hoeing at 12 DAS fb one hand weeding at 30 DAS (HH + WH) achieved the highest grain yield (4.85 t ha–1) and net returns (851.03 US$ ha–1) as well as the lowest weed density at 60 DAS. PS × HH + WH treatment combination had the lowest weed persistent index (WPI), WMI, AMI, and IWMI, and the highest growth attributes, production efficiency, and economic return.

SRI-Rice's insight:

As we move toward more integration of SRI with CA and direct-seeding, these studies are becoming more important!
