Wheat Adoption and Impact Study in Kyrgyzstan
No full textA household survey was conducted from May to October 2018 in the Chüy, Issyk-Kul, and Osh oblasts of the Kyrgyz Republic. The dataset offers insights into production patterns, the socio-economic and demographic situations of farmers and households growing wheat, factors influencing their production decisions, the adoption of new wheat varieties, and the impacts of wheat production on their livelihoods. The project received funding from CRP WHEAT.
Approximately 700 households growing wheat were interviewed. The survey was designed to collect data through face-to-face interviews. The questionnaire was supplied by CIMMYT, and its final version incorporated feedback from a pilot survey conducted in May. The questionnaire was prepared in English, Russian, and Kyrgyz. Data collection took place from June 1 to July 20, 2018
Replication Data for: Spatially differentiated nitrogen supply is key in a global food–fertilizer price crisis
No full textThe necessity for differentiated responses arises due to the significant surge in nitrogen fertilizer prices, posing a serious threat to food security. To sustain the production of staple cereals in agricultural systems with varying levels of fertilization, it becomes imperative to explore integrated management strategies encompassing both organic and inorganic nitrogen sources in high- and low-intensity cereal production.
According to estimates, adopting such an integrated approach could yield substantial reductions in nitrogen fertilizer usage: by 11% in India, 49% in Ethiopia, and 44% in Malawi. This strategy involves utilizing more cost-effective fertilizers with a high nitrogen content, such as urea, in conjunction with compost and legumes, particularly aimed at optimizing nitrogen utilization in deficient systems. Furthermore, embracing more efficient and targeted nitrogen fertilizer application would prove beneficial for systems with nitrogen surpluses. Geospatially diverse fertilization strategies should prioritize supplying nitrogen-rich fertilizers to low-yielding and nitrogen-deficient regions, while ensuring balanced fertilization of nitrogen, phosphorus, potassium, and micronutrients in high-yielding systems
Replication Data for: Two crops are better than one for nutritional and economic outcomes of Zambian smallholder farms, but require more labour
No full textSustainable intensification practices, such as intercropping maize with grain legumes, are essential for smallholder farmers in southern Africa to address climate change and declining soil fertility. A study in Zambia compared different diversification strategies (single-row intercropping, strip cropping, and crop rotation) with sole maize.
The results showed that while there were no significant differences in individual yields, intercropping systems provided important nutritional and economic benefits. However, these systems required more labor, which was not preferred by farmers. Soil organic carbon content and pH generally decreased without differences between systems. In summary, maize-legume intercropping can improve food security and agricultural benefits, although it requires more labor, which could be addressed with appropriate mechanization
Farmer field survey dataset underpinning 'Data-driven strategies to improve nitrogen use efficiency of rice farming in South Asia'.
No full textThis database integrates farmer field surveys with secondary environmental data for 45,643 farmer fields that cultivated rice between 2016 and 2021. This dataset integrates original survey datasets that have, or will be, published on the CIMMYT Dataverse. Collectively, the dataset covers six regions across South Asia: Andhra Pradesh (n=1,744), Bihar and eastern Uttar Pradesh (n=9,693), Odisha (n=1,947), Punjab and Haryana (n=5,833), Bangladesh’s floodplains (n=20,329), and the Terai region of Nepal (n=6,097). The northwestern Indian states of Punjab and Haryana are grouped together as they are commonly considered part of a distinct rice-producing area known as the ‘Trans-Gangetic Plains’. Similarly, Bihar and the neighbouring districts of eastern Uttar Pradesh—Ballia, Chandauli, Deoria, Ghazipur, Gorakhpur, Kushinagar, Maharajganj, Mau, and Siddharthnagar—are grouped together as a distinct rice production environment commonly known as the ‘Middle Indo-Gangetic Plains’. It should also be noted that the surveyed area of Bangladesh’s floodplains primarily includes the Tista Meander Floodplain and Ganges River Floodplains and may not represent other floodplain areas in Bangladesh
Replication Data for: Ms44-SPT: Unique genetic technology simplifies and improves hybrid maize seed production in sub-Saharan Africa
No full textHybrid maize seed production in Africa can face reduced yields based on the damage that may be incurred when detasseling female plants. Moreover, incomplete detasseling may lead to impurities hybrid seed production. A unique nuclear genetic male sterility seed production technology, referred to as Ms44-SPT, was developed to reduce these hybrid seed production challenges. Data collected to assess the impact of the Ms44-SPT technology on leaf loss during detasseling and on seed production are reported in this dataset
Yield of maize and wheat under permanent beds in a long-term experiment in Mexico's semi-arid highlands
No full textThis dataset includes experimental data collected from a long-term field experiment conducted over 20 years (1999-2019) in a semiarid region of central Mexico.
The study focused on evaluating the effects of various soil management practices—including the use of permanent beds, crop residue management, and tied ridges—on the yield and profitability of maize (Zea mays L.) and wheat (Triticum aestivum L.) under rainfed conditions.
The dataset includes: Grain yield data for maize and wheat, Biomass production measurements, Information on soil management practices applied during the experiment
