Narrow Row

Management practices can have a major impact on the successful production of winter cereals. A field experiment was conducted with winter wheat (Triticum aestivum) to compare the effects of two row spacing planting patterns (row width set at 30 cm, 30; or row widths set at a narrow row of 20 cm and a wide row of 40 cm, 20 + 40) and four irrigation schedules (no irrigation, T0; irrigation given at stem elongation stage, T1; at stem elongation and heading stage, T2; at stem elongation, heading and milk stage, T3) on yield, water use efficiency (WUE), evapotranspiration (ET) and soil water content (SWC) for the 2003/2004 and 2004/2005 seasons at Taian, Shandong Province, China. Mean soil daily evaporation (Es) was greater in the wide row than the narrow row, and resulted in decreased SWC in the wide row. For the same irrigation treatment, no significant differences in changes of SWC and yield were found between the row-spacing planting patterns in either season. Differences in ET were found in 2005 with ET from the T0 treatment being much lower than the irrigated treatments for both planting patterns. During the cropping season in 2005, WUE of the T3 treatment was lower than from the T1 and T0 treatments at the same planting patterns. The WUE of the 20 + 40 planting pattern was lower than that of the 30 planting pattern with the same irrigation schedule, perhaps due to elevated levels of evaporation from the soil beneath the canopy and decreased yields for the 20 + 40 planting pattern. Therefore, based on WUE, the effect of the 30 planting pattern was better than that of the 20 + 40.

Red Winter Wheat

Greenhouse and field studies were conducted to determine the effects of Wheat streak mosaic virus (WSMV), a member of the family Potyviridae, on root development and water-use efficiency (WUE) of two hard red winter wheat (Triticum aestivum) cultivars, one susceptible and one resistant to WSMV. In the greenhouse studies, wheat cultivars were grown under three water regimes of 30, 60, and 80% soil saturation capacity. After inoculation with WSMV, plants were grown for approximately 4 weeks and then harvested. Root and shoot weights were measured to determine the effect of the disease on biomass. In all water treatments, root biomass and WUE of inoculated susceptible plants were significantly less (P < 0.05) than those of the noninoculated control plants. However, in the resistant cultivar, significance was only found in the 30 and 60% treatments for root weight and WUE, respectively. Field studies were also conducted under three water regimes based on reference evapotranspiration rates. Significant reductions in forage, grain yield, and crop WUE were observed in the inoculated susceptible plots compared with the noninoculated plots. Both studies demonstrated that wheat streak mosaic reduces WUE, which is a major concern in the Texas Panhandle because of limited availability of water.
