Book Description
Irrigating soybean prior to an extensive rain can result in waterlogged soil that may cause root damage and plant death. Some soybean cultivars tolerate waterlogged soils. The objective of this study was to evaluate tolerance of soybean cultivars to waterlogged soils at different soybean growth stages and flood durations. A selection of maturity group IV soybean cultivars was screened for flood tolerance in the field. Five cultivars were selected for variations in tolerance to waterlogged soil conditions. An experiment was conducted to determine the response of these cultivars to waterlogged soil for 192 h at thee growth stages (V5, R1, and R5). A second experiment was conducted to determine the response of these cultivars to flood for 0, 48, 96, 144, and 192 h at the R1 stage of growth. A significant interaction was found between cultivars and growth stage flooding when exposed to waterlogged soil. The greatest yield suppression from waterlogged soil occurred at the R5 growth stage compared to V5 and R1. Soybean yield suppression due to waterlogged soil was least when flood was applied at V5 compared with the R1 and R5 stages of growth. Flood duration had a significant negative effect on soybean yield (P = 0.0012). When averaged across years and cultivars, soybean yields declined 310 kg ha-1 after being flooded for 192 hours at bloom compared to non-flooded checks. Significant interactions between cultivar and duration were not found.

Book Description
Increases in soybean productivity have been relatively small compared to other major economic crops. Wet-soil culture, a relatively new technique of growing soybeans under a high controlled water table, has increased soybean production potential under Australian conditions. Therefore, two field experiments during 1985 and 1986 seasons were conducted with U.S. adapted varieties at the Plant Science Research Center, Mississippi State University. The first study had twenty-four varieties from three different maturity groups tested in three soil moisture regimes: wet-soil culture + N, conventional irrigation and dry. The 1985 season showed low performance of soybean plants grown in wet-soil culture compared to conventional irrigation and dry grown beans. Thiswas due to the water table being higher than intended, which resulted in near flooding. Planting of flat beds contributed to this near flooding situation. By planting on elevated beds in 1986, the wet-soil culture outyielded the other two soil moisture regimes due to better water table control. The second study was a combination of two varieties, five rates of N and two times of initiating wet-soil culture. The varieties were Tracy-M and Centennial (Leflore in 1986). Nitrogen was surface applied as urea at five rates. Time of initiating wet-soil culture was V3 and V8 growth stages. The same problem of near flooding occurred in this experiment, as evidenced by stem splitting. This morphological change was not present in 1986. Seed yield was slightly (...).
