International Durum Screening Nursery (IDSN) distributes diverse CIMMYT-bred spring durum wheat germplasm adapted to irrigated and variable moisture stressed environments. Disease resistance and high industrial pasta quality are essential traits possessed in this germplasm. It is distributed to 100 locations, and contains 150 entries.

International Durum Yield Nurseries are replicated yield trials designed to measure the yield potential and adaptation of superior CIMMYT-bred spring durum wheat germplasm that have been developed from tests conducted under irrigation and induced stressed cropping conditions in northwest Mexico. These materials have been subjected to numerous diseases...

The Semi-Arid Wheat Screening Nursery (SAWSN) is a single replicate trial that contains diverse spring bread wheat (Triticum aestivum) germplasm adapted to low rainfall, drought prone, semi-arid environments typically receiving less than 500 mm of water available during the cropping cycle. CIMMYT's breeding approach attempts to combine high yield...

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...

The International Bread Wheat Screening Nursery (IBWSN) is designed to rapidly assess a large number of advanced generation (F3-F7) lines of spring bread wheat under Mega-environment 1 (ME1) which represents diversity for a wide range of latitudes, climates, daylengths, fertility conditions, water management, and (most importantly) disease conditions. The...

The Semi-Arid Wheat Yield Trial (SAWYT) is a replicated yield trial that contains spring bread wheat (Triticum aestivum) germplasm adapted to low rainfall, drought prone environments typically receiving less than 500 mm of water available during the cropping cycle. The combination of water-use efficiency and water responsive broad adaptation plus yield...

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...

Conservation agriculture involves reduced tillage, diversification of plant associations, and retention of crop residues to maintain soil cover. However, there is knowledge gap on the appropriate rate of application and interactive effect of residues and nitrogen as in some situations cases of nitrogen lock-up have been reported. This present data set...

The aim of this project is to document the adoption and impact of improved maize germplasm at poor, maize-dependent farmers’ level, in combination with understanding how access to affordable quality maize seed can be achieved through seed sector development. The assumption is that understanding the challenges, opportunities and implications of changes in...

The present data is from a long-term trial set at Msekera Research Station in Zambia to monitor and evaluate the the longer term effects of conservation agriculture practices on soil quality, soil water dynamics, weeds, pests/diseases and crop yield. The treatments set to investigate this are: T1: Control plot 1 (CPM1); traditional farmers practice...

This trial is designed with 1 conventional farmers practice and 4 conservation agriculture (CA) treatments in 5 replications; Plots are subdivided into a continues maize area and a maize/legume (sunnhemp) rotation to investigate the effect of CA practices on soil quality and system productivity. The trial was set in the growing season of 2005 and is still...

This data set is from a long-term (2010-2016) trial set in sandy soils. The study seeks to monitor and evaluate the effects over time of conservation agriculture (CA) practices on crop yield, soil quality, weeds, pests and diseases. The trial was set as a randomised complete block design with the following treatments: T1: Check plot (CP); traditional...

The purpose of the study was (1) to assess the economic viability of custom-hire service for ZT in CSISA's target districts in Bihar, the development of ZT service provision businesses over time, and constraints to further business expansion; (2) to assess service providers’ resource endowment, risk exposure, risk preferences, and risk management...

The purpose of the study was (1) to assess the performance of ZT wheat as compared to conventional-tillage wheat in farmers' fields in six CSISA target districts in Bihar; (2) to assess farmers’ resource endowment, risk exposure, risk preferences, and risk management practices; (3) based on (2), to identify influencing factors of farmers' awareness and...

This study contains spring wheat yield data (1st, 2nd, and 3rd WYCYTs and 1st, 2nd, 3rd and 4th SATYNs) from 136 international environments that were used to evaluate the predictive ability of different models in diverse environments by modeling G×E using the pedigree-derived additive relationship matrix (A matrix).

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...
