CIMMYT annually distributes improved germplasm developed by its researchers and partners in international nurseries trials and experiments. The High Temperature Wheat Yield Trial (HTWYT) is a replicated yield trial that contains spring bread wheat (Triticum aestivum) germplasm adapted to Mega-environment 1 (ME1) which represents high temperature areas.

Nutrient Ommission Trials (NOTs) from three states in Nigeria. Six treatments, yield, soil and ear leaf nutrient contents.

Nutrient expert performance trials (PTs) from three states in Nigeria. Four treatments, management, yield, soil

TAMASA Agronomy Panel Survey 2016/17 Season. This file contains the maize grain yield from approximately 578 maize fields in the Southern Highlands, Northern and Eastern Zones of Tanzania in collected May-August 2017. Maize grain yield data can be linked to associated maize yield and soil by the common HHID.

Experiments at multiple locations in Tanzania (800 to 1500m) to calibrate development or phenology of maize varieties. Locations are Igeri, Minja, Mitalula, Mlaaleni, Monduli, Selian, Seatondale, Suluti, Uyole, W. Kilimanjaro. Observations include dates of emergence, tassel, silking and maturity; Daily min & max temperatures are in a separate file

Nutrient Omission Trials (NOTs) conducted in two zones (West Showa and Jimma) in Ethiopia in 2015 and 2016. Trials comprise six nutrient management treatments, namely Control (zero fertilizer), PK, NK, PK, NPK, NPK+Ca+Mg+Zn+B. Trials were conducted on-farm with six plots per farm. Observations include soil analysis (0-20cm), biomass and grain yields

Nutrient Omission Trials (NOTs) from three states in Nigeria. Six treatments, yield, soil and ear leaf, stover and grain nutrient contents

Survey at multiple locations in Tanzania (680 to 2100 m) to establish baseline biomass yields at farm level.

Survey at multiple locations in Tanzania (600 to 2100 m) to establish baseline yields at farm level.

This dataset consists of soil data from Baseline Yield Survey conducted in Southern Highlands, Northern and Eastern Zones in Tanznaia. These data are associated, by location, with the yield data collected under the same baseline survey for the same areas and time period

TAMASA Tanzania Agronomic Panel Survey (APS) Soil data for 2016. Soil samples were collected at harvest time at 0-20 and 20-50 cm depths in 560 geo-referenced fields. Soils data were analysed by mid-IR and XRF methods.
