Data for: Postharvest grain system in Ecuador and small-scale farmers' perceptions of gender roles and postharvest loss

INIAP (Instituto Nacional de Investigaciones Agropecuarias) and CIMMYT implemented a postharvest diagnostic in Ecuador to document grain production and postharvest practices among small-scale farmers in Ecuador. The survey was conducted between 2021 and 2022, to characterize production systems, identify determinants of postharvest loss, and understand gendered participation across the agricultural value chain. The dataset contains the following information: (1) General household and respondent characteristics; (2) Crop production and field management; (3) Postharvest practices and loss assessment; (4) Pest management and grain use; and (5) Gender roles in agricultural and postharvest activities. This dataset provides a comprehensive resource for analyzing postharvest loss determinants, gendered labor contributions, production constraints, and grain storage practices in Ecuador’s smallholder farming systems.

2025 CIMMYT Maize Southern Africa Product Announcement

New 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 culminating in the 2024/25 Stage 5 trials, CIMMYT advanced a total of eight (8) new elite maize hybrids in Southern Africa in 2025. Phenotypic data collected in Stage 4 and Stage 5 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 NARS and private seed companies, in Southern Africa under various management and environmental conditions.

Replication Data for: Arthropods caught using malaise traps in maize and wheat in El Batan and CENEB

The database contains data on arthropods caught using Malaise traps in maize and wheat fields planted with flower strips across two agro-ecological regions of Mexico: El Batán in Estado de México, and Campo Experimental Norman E. Borlaug (CENEB) in Ciudad Obregón, Sonora. Over three years (2021-2024), arthropods were sampled regularly at five distances from the flower strips using Malaise traps, and were assigned to taxonomic and functional groups.

Maize and soybean farming practices and yields during the 2022-2023 season in Malawi, Mozambique and Zambia

This dataset describes farming practices in soybean and maize monocrop fields in Malawi, Mozambique and Zambia for the 2022-2023 growing season. Crop cuts were carried out on the fields of farmers participating in the EiA use case, as well as neighbouring farms and farms in non-implementing communities for representativeness. Data are provided as Excel spreadsheets and an .rds file (compatible with R 4.4.1). There is one table with the raw data (as recorded through KoboCollect) and one with the cleaned data used for the related manuscript. Survey data are reproduced as closely as possible to how they were recorded. Secondary data were used as indicated in the codebook.

Replication Data for: Food and nutrition security merits of intercropping maize, sorghum and millet with legumes on small farms in Southern Africa

This 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.

From farms to carbon markets: Farmers’ awareness, motivation, determinants, and impact of participating in carbon farming in India

This dataset was collected using two questionnaires developed by CIMMYT: the "Household Survey Questionnaire" and the "Lead Farmer Survey Questionnaire". The dataset includes comprehensive household-level, farm-level, plot-level, and village-level information related to carbon farming in India. The household-level data (from 841 households) covers demographics, landholding, crop production, input use, irrigation, sustainable agricultural practices, awareness and participation in carbon credit programs, payment arrangements, training, and social networks. It enables analysis of factors influencing farmers’ participation in carbon farming, adoption of sustainable practices, and the economic, environmental, and social impacts of such participation. The village-level data, provided by lead farmers—either carbon farmers or other knowledgeable farmers—includes details on cropping patterns, adoption of resource-conserving technologies, residue management practices, irrigation water availability and quality, distances to agricultural and community facilities, and specific carbon farming activities within the village. This information supports analysis of the dissemination of sustainable practices, local infrastructure and resource conditions, and the role of lead farmers in promoting carbon farming and encouraging other farmers to participate.

Impact of nitrogen split application on wheat grain yield and protein content in Conservation Agriculture

Research on the effect of split nitrogen application on wheat grain yield and quality under conservation agriculture. The study was conducted during the 2016-2017 and 2017-2018 fall-winter cycles in the Bajío region of Guanajuato. The effects of study locations, wheat varieties, nitrogen fractionation, and their interactions were evaluated.
