A regional yield trial called the East Central Africa bean yield trial was distributed in three separate groups that aligned with three breeding pipelines: Andean bush beans (Group 1 or G1), Mesoamerican bush beans (G2), and climbing beans (G3). Forty-three trials met minimal standards of data quality. Trial environments composed of a site, planting date, and its climatic parameters were clustered based on 13 variables of temperature, rainfall, relative humidity, vapor pressure deficit, and altitude. Climatic data were derived from the NASA Prediction of Worldwide Energy Resources (POWER) database, which estimates day-by-day weather for each site. Four climate clusters emerged from this analysis. Climbing bean yield corresponded to climate clusters and heavily responded to high altitude and temperature. Most Andean bush bean environments occupied a centric cluster with few extreme variables. No patterns were observed in the Mesoamerican bush beans.

These benefits persisted in the second wheat phase in the WW–WW and HRSW–WW systems, albeit with increased variability. Canola stubble, while not offering immediate advantages for WW, contributed to high and stable yields in WW and HRSW when planted in the second year. However, a wheat yield drag was noted in the second year, especially affecting HRSW, indicating that monoculture cereal rotations are more detrimental to HRSW than to WW. In-crop growth patterns aligned with yield responses, with leguminous stubbles, especially lentil, promoting superior in-season growth compared to canola, flax, and oats.

Unfortunately, irrigation management that oxidizes the soil can potentially result in higher Cd concentrations. This 2-year study tested the hypothesis that AWD with two short drains is better than a single mid-summer drain (MSD) or flood (FLD) on rice yield, element content, and various starch quality attributes. The results revealed that AWD did not reduce yield compared to MSD and FLD and that AWD and MSD resulted in a negligible milling quality penalty compared with FLD. AWD had the added benefit of significantly reducing tAs and iAs in grains compared with FLD and MSD. AWD did not increase grain Cd in brown rice when compared with FLD and caused either no consequential change or a desirable increase in 10 other elements.
