Maize Producers (Households Participated) in MCM Activities in Nepal
No full textThe dataset used in this study was collected as part of the evaluation of the Maize Commercialization Model (MCM) in Nepal, implemented under the Nepal Seed and Fertilizer (NSAF) project led by CIMMYT and funded by USAID. The dataset comprises survey responses from 493 smallholder households across five districts—Banke, Bardiya, Kailali (MCM intervention areas), and Dang, Kanchanpur (non-MCM comparison areas). The survey utilized a multistage random sampling approach, ensuring adequate representation of both male- and female-headed households (MHH and FHH). Key variables include demographic characteristics, agricultural practices, access to resources, maize productivity, and market participation. The dataset enables gender-disaggregated analysis of the impact of bundled agricultural interventions on commercialization outcomes. Data collection was conducted through structured household interviews, ensuring consistency and reliability. The dataset is anonymized to protect respondent confidentiality and is available in CSV and STATA formats for further analysis
Replication Data for: Farm production, marketing, and children's nutritional outcomes in rural Zambia
No full textThe collected data originate from a study conducted in the Eastern and Northern provinces of Zambia during the low season (December 2019 to February 2020). The sample includes 528 households selected through random sampling in various agricultural camps, with information on agricultural production, marketing decisions, seasonal food prices, food consumption, nutritional content of crops, and anthropometric measures of children under five years old. The households are located in the districts of Katete in the Eastern Province and Mbala in the Northern Province. Additionally, sociodemographic data and information on access to services were collected, along with variables related to crop diversification and household resources. The data were used to analyze the relationship between nutrient deficiencies from own production (NDOP), food sale and consumption decisions, and child growth outcomes, employing econometric methods to address potential endogeneity biases.</p
Soil properties predicted from mid-infrared spectral (MIRS) analysis of soil samples collected in 2023 (second year) before and/or after establishing on-farm trials on yield response to lime rates in Rwanda
No full textSelected soil properties were predicted from 524 topsoil samples subjected to spectral analysis (MIRS). A subset of samples were also subjected to wet chemistry analysis, and results were used to calibrate a machine-learning algorithm developed by the International Centre for Research in Agroforestry (ICRAF) in Kenya. Coordinates were truncated to protect farmer's privacy.
Unless specified, all properties were predicted. This dataset can be linked with yield data (coming soon) and previous soil analysis data (https://hdl.handle.net/11529/10549138) through the unique farm identifer "fid".

CIMMYT-derived Fall Armyworm (FAW) Tolerant Elite Maize Hybrids for Eastern and Southern Africa
No full textThe fall armyworm (FAW; Spodoptera frugiperda) has emerged as a serious threat to maize production in Africa since 2016, and in Asia since 2018. Host plant resistance is an important component of integrated pest management (IPM). Leveraging on CIMMYT’s tropical insect-resistant maize germplasm developed in Mexico, coupled with elite stress-resilient maize germplasm developed in sub-Saharan Africa, CIMMYT conducted intensive efforts over three years to identify and validate sources of native genetic resistance to FAW in Africa. This included screening more than 3500 hybrids in 2018 and 2019.
In 2020, CIMMYT evaluated a set of eight selected test hybrids (based on on-station results for FAW tolerance during trials in 2018-2019) along with four widely used commercial hybrids under different experiments/trials. The results of the trials for the three selected FAW tolerant hybrids as well as the checks are presented in this dataset
Evaluación de la comercialización y la oferta de proveedores de servicios de maquila agrícola en el sur de México y Guatemala
No full textLos datos presentados reúnen información proveniente de encuestas aplicadas a comercializadores de maquinaria agrícola y a prestadores de servicios de maquila, también conocidos como maquileros en el sur de México y Guatemala.
La información abarca aspectos como los servicios que ofrecen a los agricultores, la maquinaria disponible para la venta en el caso de los comercializadores y para la maquila en el caso de los prestadores de servicios, los canales de comunicación utilizados para llegar a sus clientes, así como la perspectiva de cada actor sobre los beneficios y las barreras que enfrentan en la implementación de la mecanización agrícola.</p
Replication Data for: Food and nutrition security merits of intercropping maize, sorghum and millet with legumes on small farms in Southern Africa
No full textThis database comprises grain and nutritional yield data from on-farm trials implemented in the Dedza and Mzimba districts of Malawi over three growing seasons (2017/18 to 2019/20).
The study was designed to evaluate yields resulting from treatments involving different cereals and legumes within intercropping systems.
The complete dataset supported the findings published in: 'Small grains for small farms? Food and nutrition security from maize, sorghum, and millet cropping systems in Southern Africa.</p
Estructura de datos y métricas de desempeño de los Puntos de Maquinaria (PDM) en México
No full text El Centro Internacional de Mejoramiento de Maíz y Trigo (CIMMYT) estableció 59 Puntos de Maquinaria (PDM) para facilitar el acceso a soluciones de mecanización sustentable, adecuadas a la escala de producción de cada región.
Los PDM funcionan como espacios físicos que ofrecen servicios de maquila o renta de maquinaria bajo esquemas accesibles. Además de su función operativa, los PDM permiten monitorear la adopción tecnológica.
Los datos recopilados contienen la identificación y ubicación geoespacial del PDM, métricas generales de desempeño (solicitudes, superficie y productores atendidos), desglose por tipo de servicio agronómico (desde labranza hasta manejo de residuos), estratificación de productores por superficie y el radio de cobertura en kilómetros.</p
DArTAG-fingerprints of CIMMTY BNI-translocation lines
No full textSeveral introgression lines carrying the BNI translocation, together with their respective recurrent spring bread wheat parents, were multiplied for distribution at CIMMYT’s Mexicali station. To confirm the presence of the target translocations and to verify line purity and genetic relationships, all materials were fingerprinted using the mid-density 3.9K TaDArTAG v2 genotyping panel in combination with KASP molecular markers
2018 CIMMYT Product Announcement and Results of the Maize Regional On-Station Trials for Southern Africa for 2018
No full textNew and improved maize hybrids, developed by the CIMMYT Global Maize Program, are available for uptake by public and private sector partners, especially those interested in marketing or disseminating hybrid maize seed across Southern Africa and similar agro-ecological zones. Following a rigorous trialing and a stage-gate advancement process CIMMYT advanced a set of new elite maize hybrids in Southern Africa in 2018. Phenotypic data collected in Stage 4 trials for the selected hybrids as well as information about the trial sites are provided in this dataset. These trials were conducted through a network of partners, including NARES and private seed companies, in Southern Africa under various management and environmental conditions
Data on performance of machine-led direct seeded rice (DSR) techniques compared to conventional rice transplanting in eastern India
No full textDirect Seeded Rice (DSR) using seed-cum-fertilizer drill is an emerging rice establishment technique in India. How the two versions of DSR (zero-till & dust mulch) are comparable with the most common conventionally transplanted rice is less known. To fill the knowledge gap, CSISA in collaboration with Krishi Vigyan Kendra (KVK) conducted on-farm agronomic trial in eastern India covering different agro-climatic zones. The trial was conducted with 10 KVKs continuously for five years starting from 2017. Across the years and geographies, it was done on 1,315 farmers' fields. The dataset formed the foundational evidence to inform initial policy handles and invites researchers to plan further research
