7th Wheat Yield Collaboration Yield Trial

Matthew Paul Reynolds Thomas Payne (2022, [Dataset])

The WYCYT international nurseries are the result of research conducted to raise the yield potential of spring wheat through the strategic crossing of physiological traits related to source and sink potential in wheat. These trials have been phenotyped in the major wheat-growing mega environments through the International Wheat Improvement Network (IWIN) and the Cereal System Initiative for South Asia (CSISA) network, which included a total of 136 environments (site-year combinations) in major spring wheat-growing countries such as Bangladesh, China, Egypt, India, Iran, Mexico, Nepal, and Pakistan.

Pathways to sustainable intensification in Eastern and Southern Africa - Kenya 2015

Paswel Marenya Menale Kassie Fulgence Mishili Gideon Obare (2017, [Dataset])

The Adoption Pathways project was part of a portfolio of projects that has contributed to the broader theme of sustainable intensification research led by the International Maize and Wheat Improvement Center (CIMMYT) and made possible by the contribution of sev eral teams from national and international research groups brought together by funding from the Australian Centre for International Agricultural Research (ACIAR). The project was undertaken in the five Eastern and Southern African countries of Ethiopia, Kenya, Malawi, Mozambique and Tanzania. 1. Gender disaggregated three wave panel data set (2010/11, 2013), building on a legacy dataset collected under a related ACIAR funded project (SIMLESA) is now being developed covering close to 3500 households in each data wave across the five project countries. The 2015/16 data will be available in due course. 2. Several empirical evaluations of the gender gaps in technology adoption, food security and market access have been completed and published. 3. These results have been shared in various policy forums including but not limited to annual project meetings. In order to achieve its full impact in the coming years; we propose that new projects and initiatives based on the work of the Adoption Pathways project be established. These should focus on capacity building for the analysis of panel datasets, continued work on studying intrahousehold input allocation and sharing of agricultural output and scaling up the findings from this project to influence next generation of sustainable agriculture policies.

Replication data for: Response of secondary growth parameters in maize (Zea mays L.) to conservation agriculture and conventional tillage systems in multi environments of Zimbabwe

Christian Thierfelder Blessing Mhlanga (2017, [Dataset])

Conservation agriculture (CA) had recently gained popularity and promotion in the southern parts of Africa. Research has shown a number of benefits of CA in contrast to the widely practiced conventional ways (CP), which chiefly include water and soil conservation. These gains have positive benefits towards grain yield in maize. However, the maize varieties that performs better than others in these different environments have to be investigated and updated for farmers and breeding purposes. Furthermore, physiological traits that are suitable for the CA system needs to be dissected for breeding purposes. Hence a study was conducted across Zimbabwe at University of Zimbabwe farm (heavy red clay), Domboshawa Training centre (DTC) (sandy loamy soils), Madziva (sandy soils), Hereford (red clays) and Zimuto (sandy soils) from 2012 up to 2015. Investigations of effects of CA and CP practices on emergence, chlorophyll content, early vigour , biomass and grain yield of different maize varieties using 12 hybrids and 4 open pollinated varieties (OPVs) were conducted. Emergence was collected as the number of days taken by the different varieties to emerge. At 6 weeks after sowing a destructive sampling was performed to quantify the vigor of the maize varieties using averages of height, number of leaves per plant, dry matter and chlorophyll content using a SPAD meter. At harvesting grain yield and biomass yield were calculate d.

Increase in sustainable agricultural production in Mozambique through drought tolerant maize and conservation agriculture

Christian Thierfelder (2016, [Dataset])

The objective of this work set is to demonstrate the best options currently available for the management of conservation agriculture (CA) practices in different communities in Mozambique. Eleven communities were selected from the districts of Sofala, Tete and Manica (approximately 100 to 200 families in each community) to host these demonstration sites and six demo fields were installed in each community from 2006-2015 (9 seasons). The treatments in each community were as follows: 1. Farmers' practice (control)- Traditional management with removal of stubble. 2. Conservation agriculture- The stubble is kept in the ground, there is no preparation of the ground, and the sowing is done manually in covachos previamento open (see the management of the covachos) and with SULCADOR in Nhamatiquite. 3. Direct sowing (SD): The stubble is kept in the soil, the direct sowing is done with Matraca or sharp bread.

1st to 23rd Elite Selection Wheat Yield Trial

Ravi Singh Thomas Payne (2017, [Dataset])

The Elite Selection Wheat Yield Trial (ESWYT) is a replicated yield trial that contains spring bread wheat (Triticum aestivum) germplasm adapted to Mega-environment 1 (ME1) which represents the optimally irrigated, low rainfall areas. Major stresses include leaf, stem and yellow rusts, Karnal bunt, and lodging. Representative areas include the Gangetic Valley (India), the Indus Valley (Pakistan), the Nile Valley (Egypt), irrigated river valleys in parts of China (e.g. Chengdu), and the Yaqui Valley (Mexico). This ME encompasses 36 million hectares spread primarily over Asia and Africa between 350S -350N latitudes. White (amber)-grained types are preferred by consumers of wheat in the vast majority of the areas. It is distributed to upto 200 locations and contains 50 entries.
