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...

Breeding analyses may include pedigree information and genotypic data. The wheat data in this dataset were used to asssess the accuracy of genomic predictons when the pedigree or genetic similarity matrix is combined with the genomic similarity matrix. This study included 5 single-environment models 5 multi-environments models with genotype-by-environment...

This dataset contains variety-level seed production and sales data of 297 public and private maize seed producers in Mexico during the period 2011-2019. The dataset was compiled using four different sources. The first is the MasAgro seed marketing survey, administered from 2013 to 2019 to MasAgro affiliated seed companies to monitor their seed sales and...

Every year, the MasAgro maize component of the Sustainable Modernization of Traditional Agriculture project (MasAgro) established a seed evaluation network in the three mega-environments of maize production in Mexico (Subtropic, Tropic and Highlands) to evaluate all materials developed by CIMMYT breeders for MasAgro, and assess their performance vis-à-vis...

To dissect the genetic architecture of grain yield and flowering traits under drought stress, a genome-wide association study (GWAS) was conducted using 236 test-crossed maize lines. The materials were evaluated under managed drought and optimal growing conditions in multiple environments using seven multi-locus GWAS models (mrMLM, FASTmrMLM, FASTmrEMMA,...

Selected soil properties were predicted from 71 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...

Selected soil properties were predicted from 104 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...

Selected soil properties were predicted from 79 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...

El presente conjunto de datos muestra el desensamble de un tractor de dos ruedas y una sembradora para animal de tiro para estudiar el proceso de manufactura, identificando pieza por pieza su diseño, perfil, tamaño, calibre, masa y volumen del material.

El consumo de combustible de una operación agrícola puede obtenerse a partir del consumo horario que presenta el motor del tractor durante la operación y el tiempo que se necesita para completar dicha operación. Con el objetivo de recolectar información sobre el consumo de combustible en tractores agrícolas al realizar diversas tareas en el ciclo de...

CIMMYT implemented a study at its station in Texcoco, Mexico to compare the effectiveness of 7 different commercially available shelling options for smallholder farmers in Mexico (OCT: hand sheller; DSG: manual crank-type sheller; THDG: pedal sheller; DEZ: electric sheller of Chinese make; RDI: electric rotating-disc sheller; MKT: two-wheel tractor,...

The sorghum data was collected from small-scale sorghum farmers in the Tanzanian regions of Dodoma and Shinyanga in November and December 2023. In the Dodoma region, two districts were selected: Kondoa and Kongwa, while in the Shinyanga region, the districts selected were Kishapu and Shinyanga. The sample size consists of 1,100 small-scale farmers. The...

This 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...

Hybrid 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...

Field and greenhouse FHB resistance evaluation for a panel of African wheat varieties, with deoxynivalenol (DON) toxin data provided.

CIMMYT implemented a study at its station in Texcoco to compare the effectiveness of 5 different storage technologies in minimizing grain loss during four consecutive storage cycles. In each storage cycle, the conventional practice of farmers in the area, polypropylene bag, was compared to four hermetic plastic bags from three different brands ((1)...

Data generated to understand the retention and bioavailability of iron and zinc during chapati and leavened bread production

The integrated BEM and e-Agrology dataset comprises historical data from 2012 to 2022, specifically collected from the Bajío region in Mexico, which includes the states of Guanajuato, Jalisco, Michoacan, and Queretaro. This dataset offers comprehensive information on farmers' field activities, plot details, and specific characteristics of various crops,...

This 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...

The groundnut data was collected from small-scale groundnut farmers in the Tanzanian regions of Dodoma, Shinyanga, Mtwara, Lindi, and Songwe in May and November 2023. The sample size consists of 2,200 small-scale farmers. The phase one data responses are from farmers in Dodoma and Shinyanga, collected in May 2023, while the phase two data is from farmers...
