The potential of conservation agriculture in increasing yield and tackling climate change

A multitude of research on the benefits of conservation agriculture in South Asia has predominantly focused on favorable environments where farmers have reliable access to energy supporting irrigation and inputs.

In this new publication, scientists from the International Maize and Wheat Improvement Center (CIMMYT) explore the performance of conservation agriculture in under-developed coastal environments in southern coastal Bangladesh over a period of three consecutive years, including under rainfed conditions and/or with limited application of irrigation.

Responding to the identified research gap, this research tests the hypothesis that seasonally alternating tillage (SAT) practices that alternate between strip-tillage in the winter season for maize and conventional tillage (CT) prior to rice can reduce energy use, increase energy productivity, and reduce yield-scaled emissions while increasing or maintaining yield and profit, even under these challenging conditions.

Working with 35 farmers who managed experiments in partially irrigated and rainfed environments in southern coastal Bangladesh, researchers teamed up with farming communities to compare the full suite of conservation agriculture to SAT practices against CT and farmer’s own practices.

The research found that in these coastal environments, both conservation agriculture and SAT practices have the potential to increase cereal yields and energy productivity while reducing yield-scaled emissions, thereby enabling farmers even in challenging coastal environments to produce more while reducing energy use and mitigating greenhouse gas emissions.

However, in consideration of farmers’ aversion to the elimination of tillage in rice, the research suggests that adaptations in CA practices and seasonal tillage prior to rice may be a more practical fit for rice-maize systems managed by smallholders reluctant to eliminate tillage for rice in coastal Bangladesh.

This research gives implications for future research and development efforts to take into consideration farmers’ preferences or the trade-offs resulting from significant change to conservation agriculture management in otherwise fully tilled systems. It is also vital to integrate development efforts that focus not only on agronomic management, but also on building supportive value chains to improve availability and affordability of the inputs and farm machinery required to successfully establish crops with such practices.

The power of data in improving conditions for female farmers

Despite women’s essential role in agrifood systems, their contribution can be overlooked, with resources instead targeted towards their male counterparts.

However, advancements in technology now allow scientists to generate rich datasets that can aid analysis of the situational factors impacting women farmers’ participation in extension training services.

These developments have enabled scientists from the International Maize and Wheat Improvement Center (CIMMYT), Michigan State University, and Agricultural Advisory Society, a local NGO, to understand barriers to access and recommend improvements that will benefit women in Bangladesh.

Using a large dataset of 131,073 farmers in Bangladesh, researchers worked to identify ways to tackle gender exclusion in extension training. Scientists used machine learning to understand preferences according to gender and applied optimization theory and identified actionable ways to increase the number of farmers participating in video- and multi-media mediated trainings, while simultaneously improving gender inclusivity in public training events.

The study discovered strong gender specific considerations, such as the training session’s day of the week and time and the gender of the trainer, which prevented women from or encouraged them to take part in educational events.

It also demonstrates the potential for big data to transform our understanding of unstructured and semi-structured data into statistically verifiable insights that can genuinely impact farmer’s lives. Optimizing women’s involvement in agrifood systems can additionally play an important part in efforts to enhance farm productivity, gender and social inclusion, and nutrition in Bangladesh and beyond.

Essential actions to mitigate the food crisis, stabilize supply and transition to greater agrifood system resilience

As the Russia-Ukraine war continues to degrade global food security, a new analysis lays out concrete actions that governments and investors must do now to mitigate near-term food security risks and stabilize wheat supplies, while transitioning toward long-term resilience.

The guidance, published in Nature Food by scientists from the International Maize and Wheat Improvement Center (CIMMYT) and partners, lays out short-, medium- and long-term steps to respond to the global food crisis and ultimately lead to a more resilient global agrifood system.

“The Russia-Ukraine war will impact global food security over months — if not years,” said CIMMYT Global Wheat Program Director and lead author Alison Bentley. “We now need to move beyond defining the problem to implementing practical actions to ensure stable supply, safeguard the livelihoods of millions of vulnerable people and bring resilience to our global agrifood system.”

The war in Ukraine and trade sanctions against Russia are triggering a level of volatility that could easily overwhelm existing mitigation mechanisms. More than 2.5 billion people worldwide consume wheat-based foods; those in lower- to middle-income countries dependent on imports from Russia and Ukraine are particularly affected. Some of the world’s poorest countries, such as Bangladesh, Sudan and Yemen, rely heavily on Russian and Ukrainian wheat. Given the highly interconnected nature of contemporary agrifood systems, few will remain unaffected by this new global food shock.

Mitigate the immediate crisis

The first priority, according to the authors, is to mitigate the immediate crisis by boosting wheat production in existing high- and low-productivity areas, ensuring grain access and blending wheat flour with other low-cost cereals. Bundled agronomic and breeding improvements and sustainable farming practices can reduce dependence on imported grain and fertilizer, while coordinated, multilateral policies can help conserve grain stocks for human consumption and avert trade restrictions.

Increase the resilience of wheat supply

In the medium term, the authors emphasized the need to increase the local, regional, and global resilience of the wheat supply. This can be done by expanding production within agro-ecological boundaries, supporting national wheat self-sufficiency and providing technical assistance, to increase the production of high-yielding disease-resistant wheat and to mainstream capacity for pest and disease monitoring.

Transition to system-level resilience

Finally, to reach crucially needed resilience in the world’s agrifood system, long-term measures must be taken that encompass agroecosystem diversity, address gender disparities in agriculture and rural communities and sustain increased investment in a holistic, agrifood transition.

“The current global food crisis underscores and compounds existing inequalities in our global food system,” Bentley said. “A transition to agrifood system resilience requires us to urgently balance global food supply needs with the multi-layered challenges of climate change, achieving gender equity, nutritional sufficiency and livelihood security.”

Researchers from the International Maize and Wheat Improvement Center (CIMMYT) are conducting a study in the state of Bihar, India, to improve our understanding of women’s and men’s contributions to decision-making around wheat crop management. The results will help reach women with new varieties that meet their needs and priorities.

The study seeks to overcome a big challenge for research organizations and national policymakers: to design a better framework for faster turnover of improved varieties and increased access to women and marginalized farmers.

Wheat is the second-largest crop grown in Bihar after rice, with a production of 5-6 million tonnes of it every year. Despite women’s contributions to farming activities, from sowing to harvesting, traditional gender norms can undermine their access to productive resources and influence household decisions. Additionally, women’s workload in wheat agriculture is increasing, due to men’s departure to non-agricultural jobs, but women are still not necessarily recognized as capable farmers.

Gender exclusion in agriculture

Given social norms and household-and-farm labor division based on gender, women are often confined to specific roles in the agricultural production system. In smallholder farming communities of South Asia like Bangladesh, India, and Nepal, men’s increasing involvement in non-agricultural activities has increased women’s workloads in every sphere of agricultural production. However, these long-held assumptions of their role can lead to exclusion from decision-making, limiting their control over what, how, and how much a crop is produced, their economic wellbeing, including household food security.

The CIMMYT study on “Intra-household gender dynamics in decision-making for wheat crop management in India (Bihar)” investigates women’s and men’s roles in production decisions. Led by Hom Gartaula, Gender, and Social Inclusion Specialist at CIMMYT, it covers eight villages — four in Darbhanga and four in Madhepura district — with 25 houses considered in each village.

As part of the Accelerating Genetic Gains in Maize and Wheat for improved livelihoods in Asia and Africa (AGG)  project, the research study will help gain deeper insights into the intra-household gender dynamics. It will also help in untangling who does what, how wheat cultivation and management decisions are organized within the households and the perceptions of the male and female farmers around why decisions are made in such a way.

Storytelling through household decision-making scenarios

In traditional rural societies, survey-based data collection might not be the best way to evaluate women’s agency, as the deeply rooted cultural restrictions might not allow them to talk openly about sensitive issues, like their relationship with a spouse. This study uses an innovative storytelling approach to data collection: using vignettes, farmers are given short stories to relate to their household circumstances. Stories are also easier to remember and help build a connection with the characters quickly.

The vignettes approach was first applied in the context of smallholder maize production in Kenya under the AGG project. According to Rachel Voss, the leader of the Kenyan study, “Using vignettes to explore decision-making in both East Africa and South Asia allows us to learn and compare across these regions and across crops. Gender relations in Indian wheat and Kenyan maize production might look similar in some ways, but very different in other ways, and our research and programming will need to respond to those differences.”

In this study, five vignettes with fictitious husband and wife characters are presented to participants to represent the different ways production and consumption decisions are made in the household. These vignettes describe how they engage in key decisions like seed procurement, labor hired, and harvest used for consumption or sale. With guidance from evaluators, respondents identify which scenario best aligns with the decision-making process in their household.

Researchers feel this qualitative data, gathered through a storytelling approach, could guide the reach of gender interventions in a more effective way. Gartaula and the team explained that the participants can build connections to a character in the story without biases, expressing their experiences in household decision-making through vignettes. They also observed that sometimes what the participant shared is the opposite of their assumption of women being excluded from decisions.

Rethinking gender roles

Traditional gender roles are deeply entrenched in the region. In the farming communities of rural Bihar, one might assume that who does what in wheat-rice cultivation is obvious, and it has been well studied in the past. However, investigating the stereotypes around gender to understand practices within households is an innovative aspect of this study.

For example, landless couple Pappu Paswan and Kamini Devi of village Kamtaul in Darbhanga district have been cultivating wheat on leased farm plots for many years. Devi is engaged in every aspect of decision-making. “We cultivate in leased plots of different sizes, spread across, requiring more effort and time in attending to them. We discuss additional labor during harvest and if there is money enough to pay them,” said Devi pointing her finger at the vignette illustrating ‘cooperation’ in household decision-making. They produce enough for their consumption, but when possible, “I advise my husband to sell some for income,” she added.

Despite contributing to decisions jointly with Pappu when it comes to farm labor and household finances, Devi has little or no knowledge of seed varieties and access. Her husband informs that it was UP262 (wheat seed variety) they have been cultivating for the last two years.

In Rishikesh Ram’s household, land ownership and livelihood specialization were factors in decision-making. He owns the land and makes all farming decisions, including how much will be saved for consumption at home. His wife, Kiran Devi, a nurse at the village primary health center, is hardly involved in any farming work. “As the income from her job contributes to expenses at home, decisions about loans or payment for labors on the farm are joint decisions,” Ram said.

“In these two households of the diverse decision-making process, different approaches to messaging and relevant extension services must be explored to address the issues of exclusion, access, and knowledge gaps in these households,” Gartaula observed.

Bridging the gender gap in agri-food systems

With the feminization of agriculture in the region, women’s contribution to agricultural production is likely to increase. Policy and research interventions must recognize this growing population and support their full economic and social contributions as cultivators, entrepreneurs, and laborers. However, whether women’s growing role in wheat production leads to increased decision-making authority and empowerment is still unknown. But hope is that AGG-supported gender research in South Asia and East Africa will help guide actions on gender and social inclusion in agri-food systems and support cross-learning between the regions.

A climate-smart remodeling of South Asia’s rice-wheat cropping is urgent

A climate change hotspot region that features both small-scale and intensive farming, South Asia epitomizes the crushing pressure on land and water resources from global agriculture to feed a populous, warming world. Continuous irrigated rice and wheat cropping across northern India, for example, is depleting and degrading soils, draining a major aquifer, and producing a steady draft of greenhouse gases.

Through decades-long Asian and global partnerships, the International Maize and Wheat Improvement Center (CIMMYT) has helped to study and promote resource-conserving, climate-smart solutions for South Asian agriculture. Innovations include more precise and efficient use of water and fertilizer, as well as conservation agriculture, which blends reduced or zero-tillage, use of crop residues or mulches as soil covers, and more diverse intercrops and rotations. Partners are recently exploring regenerative agriculture approaches — a suite of integrated farming and grazing practices to rebuild the organic matter and biodiversity of soils.

Along with their environmental benefits, these practices can significantly reduce farm expenses and maintain or boost crop yields. Their widespread adoption depends in part on enlightened policies and dedicated promotion and testing that directly involves farmers. We highlight below promising findings and policy directions from a collection of recent scientific studies by CIMMYT and partners.

Getting down in the dirt

A recent scientific review examines the potential of a suite of improved practices — reduced or zero-tillage with residue management, use of organic manure, the balanced and integrated application of plant nutrients, land levelling, and precise water and pest control — to capture and hold carbon in soils on smallholder farms in South Asia. Results show a potential 36% increase in organic carbon in upper soil layers, amounting to some 18 tons of carbon per hectare of land and, across crops and environments, potentially cutting methane emissions by 12%. Policies and programs are needed to encourage farmers to adopt such practices.

Another study on soil quality in India’s extensive breadbasket region found that conservation agriculture practices raised per-hectare wheat yields by nearly half a ton and soil quality indexes nearly a third, over those for conventional practices, as well as reducing greenhouse gas emissions by more than 60%.

Ten years of research in the Indo-Gangetic Plains involving rice-wheat-mungbean or maize-wheat-mungbean rotations with flooded versus subsoil drip irrigation showed an absence of earthworms — major contributors to soil health — in soils under farmers’ typical practices. However, large earthworm populations were present and active under climate-smart practices, leading to improved soil carbon sequestration, soil quality, and the availability of nutrients for plants.

Rebooting marginal farms by design

Using the FarmDESIGN model to assess the realities of small-scale, marginal farmers in northwestern India (about 67% of the population) and redesign their current practices to boost farm profits, soil organic matter, and nutritional yields while reducing pesticide use, an international team of agricultural scientists demonstrated that integrating innovative cropping systems could help to improve farm performance and household livelihoods.

More than 19 gigatons of groundwater is extracted each year in northern India, much of this to flood the region’s puddled, transplanted rice crops. A recent experiment calibrated and validated the HYDRUS-2D model to simulate water dynamics for puddled rice and for rice sown in non-flooded soil using zero-tillage and watered with sub-surface drip irrigation. It was found that the yield of rice grown using the conservation agriculture practices and sub-surface drip irrigation was comparable to that of puddled, transplanted rice but required only half the irrigation water. Sub-surface drip irrigation also curtailed water losses from evapotranspiration and deep drainage, meaning this innovation coupled with conservation agriculture offers an ecologically viable alternative for sustainable rice production.

Given that yield gains through use of conservation agriculture in northern India are widespread but generally low, a nine-year study of rice-wheat cropping in the eastern Indo-Gangetic Plains applying the Environmental Policy Climate (EPIC) model, in this case combining data from long-term experiments with regionally gridded crop modeling, documented the need to tailor conservation agriculture flexibly to local circumstances, while building farmers’ capacity to test and adapt suitable conservation agriculture practices. The study found that rice-wheat productivity could increase as much as 38% under conservation agriculture, with optimal management.

Nitrogen-Efficient Wheat Production Systems in the Indo-Gangetic Plains through Biological Nitrification Inhibition (BNI) Technology

The Nitrogen-Efficient Wheat Production Systems in the Indo-Gangetic Plains through Biological Nitrification Inhibition (BNI) Technology project aims to raise awareness of the benefits of new nitrogen-efficient wheat production systems among stakeholders in India.

By introducing technologies that maintain crop yield and quality, even with a reduced amount of nitrogen fertilizer, this project will also lessen the footprint of food production systems and combat environmental degradation.

Rapid Point-of-Care Diagnostics for Wheat Rusts (MARPLE)

MARPLE (Mobile And Real-time PLant disEase) diagnostics is a new innovative approach for fungal crop pathogen diagnostics developed by Diane Saunders’s team at the John Innes Centre.

MARPLE is the first operational system in the world using nanopore sequencing for rapid diagnostics and surveillance of complex fungal pathogens in situ. Generating results in 48 hours of field sampling, this new digital diagnostic strategy is leading revolutionary changes in plant disease diagnostics. Rapid strain level diagnostics are essential to quickly find new emergent strains and guide appropriate control measures.

Through this project, CIMMYT will:

  • Deploy and scale MARPLE to priority geographies and diseases as part of the Current and Emerging Threats to Crops Innovation Lab led by Penn State University / PlantVillage and funded by USAID’s Feed the Future.
  • Build national partner capacity for advanced disease diagnostics. We will focus geographically on Ethiopia, Kenya and Nepal for deployment of wheat stripe and stem rust diagnostics, with possible expansion to Bangladesh and Zambia (wheat blast).
  • Integrate this new in-country diagnostic capacity with recently developed disease forecasting models and early warning systems. Already functional for wheat stripe rust, the project plans to expand MARPLE to incorporate wheat stem rust and wheat blast.

Transforming Smallholder Food Systems in the Eastern Gangetic Plains (Rupantar)

The Transforming Smallholder Food Systems in the Eastern Gangetic Plains (Rupantar) project aims to define the processes and practices (technical options, scaling interventions, policy settings and implementation) that can be applied to achieve sustainable, efficient, diversified food systems at scale in the Eastern Gangetic Plains of Bangladesh, India and Nepal.

Home to 450 million people, this region has the world’s highest concentration of rural poverty and strong dependence on agriculture for food and livelihoods. Productivity remains low and diversification is limited due to poorly developed markets, sparse agricultural knowledge and service networks, inadequate development of available water resources, and low adoption of improved, sustainable production practices.

Rupantar builds on existing work and partnership networks to link research outputs and development goals through the demonstration of inclusive diversification pathways, definition of processes for scaling to the millions of smallholder farmers in the region, and generating a better understanding of the policies that support diversification.

Research objectives

  • Defining the processes and practices (technical options, scaling interventions, policy settings and implementation) that can be applied to achieve sustainable, efficient, diversified food systems at scale in the Eastern Gangetic Plains.
  • Understanding the context for diversification in the Eastern Gangetic Plains.
  • Defining and implementing diversification pathways using collaborative and inclusive approaches.
  • Deepening understanding of the trade-offs and synergies associated with diversification pathways.
  • Engaging and communicating with change-makers to ensure outputs are used and integrated into independent programs.

Project outcomes

  • Demonstrated pathways for equitable and sustainable diversified food systems in the EGP.
  • Improved evidence-based policies for planning and development programs that promote diversification.
  • Self-sustaining diversification pathways that are owned by local partners and promoted without ongoing project support.

Two approaches better than one: identifying spot blotch resistance in wheat varieties

Spot blotch, a major biotic stress challenging bread wheat production is caused by the fungus Bipolaris sorokiniana. In a new study, scientists from the International Maize and Wheat Improvement Center (CIMMYT) evaluate genomic and index-based selection to select for spot blotch resistance quickly and accurately in wheat lines. The former approach facilitates selecting for spot blotch resistance, and the latter for spot blotch resistance, heading and plant height.

Genomic selection

The authors leveraged genotyping data and extensive spot blotch phenotyping data from Mexico and collaborating partners in Bangladesh and India to evaluate genomic selection, which is a promising genomic breeding strategy for spot blotch resistance. Using genomic selection for selecting lines that have not been phenotyped can reduce the breeding cycle time and cost, increase the selection intensity, and subsequently increase the rate of genetic gain.

Two scenarios were tested for predicting spot blotch: fixed effects model (less than 100 molecular markers associated with spot blotch) and genomic prediction (over 7,000 markers across the wheat genome). The clear winner was genomic prediction which was on average 177.6% more accurate than the fixed effects model, as spot blotch resistance in advanced CIMMYT wheat breeding lines is controlled by many genes of small effects.

“This finding applies to other spot blotch resistant loci too, as very few of them have shown big effects, and the advantage of genomic prediction over the fixed effects model is tremendous”, confirmed Xinyao He, Wheat Pathologist and Geneticist at CIMMYT.

The authors have also evaluated genomic prediction in different populations, including breeding lines and sister lines that share one or two parents.

Index selection

One of the key problems faced by wheat breeders in selecting for spot blotch resistance is identifying lines that are genetically resistant to spot blotch versus those that escape and exhibit less disease by being late and tall. “The latter, unfortunately, is often the case in South Asia”, explained Pawan Singh, Head of Wheat Pathology at CIMMYT.

A potential solution to this problem is the use of selection indices that can make it easier for breeders to select individuals based on their ranking or predicted net genetic merit for multiple traits. Hence, this study reports the first successful evaluation of the linear phenotypic selection index and Eigen selection index method to simultaneously select for spot blotch resistance using the phenotype and genomic-estimated breeding values, heading and height.

This study demonstrates the prospects of integrating genomic selection and index-based selection with field based phenotypic selection for resistance in spot blotch in breeding programs.

Inspiring change through agricultural training: Women’s stories from Bangladesh

More than 40% of the global agricultural labor force is made up of women, and in the least developed countries, two in three women are employed in farming. Yet, despite being the largest contributors to this sector, women’s potential as farmers, producers and entrepreneurs is frequently untapped due to gender inequalities, limited access to farming assets and inputs, low participation in decision-making spaces, and lack of financing and capacity-building opportunities.

Tackling these gendered barriers is critical not only to help women achieve their highest economic potential, but also to feed an increasingly hungry world. Before this year’s Women’s History Month comes to an end, read the stories of three Bangladeshi women—Begum, Akter and Rani—to find out how the International Maize and Wheat Improvement Center (CIMMYT) are empowering them to become decision-makers in their communities, learn new skills and knowledge to boost their incomes, and advocate for bending gender norms across the country.

Embracing agricultural mechanization has improved Begum’s family finances

Rina Begum lives in Faridpur, a major commercial hub in southern Bangladesh. Before starting a business, her financial situation was precarious. Her primary source of income was her husband’s work as a day laborer, which brought in very little money. This, coupled with the lack of job security, made it hard to support a family.

Rina Begum started out in business as a service provider, hiring agricultural machines to farmers.

About five years ago, Begum’s interest in agricultural mechanization was ignited by the farmers in her town, who were earning extra money by investing in farm machinery and hiring it out. Her first foray into the business world was buying a shallow irrigation pump and setting herself up as a service provider. Next, she saw her neighbor using a power tiller operated seeder and decided to try one out for herself. Finally, after taking part in a potential machinery buyer program run by CIMMYT under the Cereal Systems Initiative for South Asia – Mechanization and Irrigation (CSISA-MEA) and funded by USAID, she took the bold step of purchasing a seeder and adding it to her inventory of machines available for hire.

While her husband learned to operate the seeder, Begum put her business and accounting skills to good use, taking on an essential role in what ended up being the family business and establishing herself as an entrepreneur. Her work defied the established social norms, as she regularly interacted with the mechanics and farmers who came to her for mechanized services. Moreover, she occasionally stepped up alongside her husband to repair and maintain the machines. All this earned Begum a reputation as an experienced service provider, operator and mechanic, and turned her into a decision-maker and a role model to her family and community.

In 2021, Begum used her business profits to pick up the bill for her daughter’s marriage. “I know this job inside-out now,” she says, “and I’m really proud to have paid for the wedding myself.”

This taste of success fueled Begum’s appetite to expand the business even further, pushing her to take part in another training offered by CIMMYT, this time in mat-seedling production. Moreover, Begum, who plans to grow seedlings to sell on to rice farmers this year, has applied for a government subsidy to buy a rice transplanter, which can be hired out for use with mat-seedlings, and increase her stock of agricultural machinery.

With her new skills, Akter is advancing gender equality in Bangladesh’s light engineering sector

At age 18, Nilufar Akter (pictured top) passed her high school certificate and soon after married Rezaul Karim, the owner of a light engineering workshop in Bogura, a city in northern Bangladesh, that manufactures agricultural machinery parts, with a workforce mainly composed of men. Akter’s ambition was to go out into the workplace and make her own money, so when Karim asked her to work alongside him, she agreed and soon became a valuable part of the business. Her primary responsibilities were inventory management and marketing, as well as business management, which she found more difficult.

Reza Engineering Workshop began working with CIMMYT in 2020 as part of CSISA-MEA, an initiative that supports light engineering workshops in Bangladesh with staff development, access to finance, management, and business growth. Under this project, CIMMYT organized a management training at the Bangladesh Agriculture Research Institute (BARI), which Akter attended. With the confidence these new skills gave her, she went back to the workshop and introduced a few changes, including building a computerized finance management system and updating the stack management. Moreover, she also established a dedicated restroom for female employees.

“We need human resources to maintain things in the business—and women can do a fantastic job”, Akter says. “We had no idea what good source of strength women workers would be for the factory. Therefore, if we provided them with adequate facilities, we could create jobs for many women who really need them”, she adds.

Akter’s current priorities are workshop safety and occupational health, two issues she’s tackling using the knowledge she learned in the CIMMYT training. Recently, she’s created some occupational health and safety posters, and established a series of workshop rules. “I used to think I wasn’t cut out for light engineering because it was primarily male-dominated, but I was mistaken”, Akter confesses. “This industry has a lot to offer to women, and I’m excited at the prospect of hiring more of them”, she adds.

Producing better quality rice has boosted the income of Rani and her family

Monika Rani lives in Khoshalpur, a village located in Dinajpur district in northern Bangladesh, with her husband Liton Chandra Roy and their two-year-old child. They farm just a quarter of a hectare of land, and Liton supplements their income with occasional wages earned as a day laborer.

Monika Rani wanted to increase her family’s income to provide better schooling opportunities for her children.

Rani was looking for ways to increase their income so they could give their children an education and a better life. During last year’s boro rice-growing season (December to May), she and her husband joined the premium grade rice production team of CIMMYT as part of CSISA-MEA. The market value and yield of premium quality rice is greater than other types, so when Rani heard that she could make more money producing that variety, she decided to make a start right away. CIMMYT provided her with five kgs of premium seed for the 2021-22 winter season and trained her in premium quality rice production technology and marketing, which she followed to the letter.

Through hard work and persistence, Rani and her husband avoided the need to hire any additional labor and were rewarded with the maximum yield possible. She dried the premium quality rice grain according to buyer demand and sold 1,600 kgs, in addition to 140 kgs to farmers in her town.

“Knowing about premium quality rice production has tremendously changed my future for the better,” Rani explains. “I had no idea that, through my own hard effort, I could have a better life”, she added.
