WheatfieldA

WheatfieldA is a designated experimental wheat field in the Central Plains region, used for agronomic research and variety evaluation. Administered by the National Agricultural Research Agency, the field covers about 150 hectares and hosts multi-year trials comparing modern bread wheat cultivars under varying management practices.

The field lies near the town of Riverbend, at an elevation around 180 meters. Soils are predominantly loamy with moderate fertility. The climate is temperate, with mean annual precipitation of 600 mm and a growing season that typically runs from late spring to early autumn.

History: Established in 2005 as part of a national program to accelerate wheat improvement. It has since hosted numerous cultivar evaluations and agronomy experiments, and its data have supported breeding releases and extension recommendations.

Research and methods: WheatfieldA runs replicated trials using randomized complete block designs to assess yield, grain protein, test weight, and milling quality across varieties. Experiments examine fertilizer rates, nitrogen timing, tillage systems, irrigation (where applicable), and pest management strategies.

Significance and impact: Findings inform breeding programs, input optimization, and policy guidance; the site also facilitates collaboration with universities and seed companies.

Access and management: Managed by NIAR Field Stations; access is restricted to authorized personnel; safety protocols and data collection schedules are published to researchers and partner institutions.

Notable events: 2012 drought-response trials demonstrated resilience differences among cultivars; 2018 integrated sensor networks and variable-rate technology; 2020 data portal release.
