Water use efficiency (WUE) and response of grape vines (Vitis vinifera L. cvs. ‘Cabernet Sauvignon’, ‘Merlot’, and ‘Viognier’) to a particle film treatment (PFT) under varying levels of applied water were evaluated in Victoria, Australia, and southwestern Idaho. Vines that received the least amount of water had the warmest canopy or leaf surface temperature and the lowest (more negative) leaf water potential, stomatal conductance (gS), transpiration (E), and photosynthesis (A). Vines with plus-PFT had cooler leaf and canopy temperature than non-PFT vines; however, temperature difference resulting from irrigation was greater than that resulting from PFT. In well-watered vines, particle film application increased leaf water potential and lowered gS. Point-in-time measurements of WUE (A/E) and gS did not consistently correspond with seasonal estimates of WUE based on carbon isotope discrimination of leaf or shoot tissue. The response of vines with particle film to undergo stomatal closure and increase leaf water potential conserved water and enhanced WUE under non-limiting soil moisture conditions and the magnitude of response differed according to cultivar.

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.

SUMMARYThe effects of planting pattern and irrigation on the soil water content, stomatal conductance, leaf relative water content, leaf water potential and leaf water use efficiency of winter wheat were investigated in North China during the 2008/09 and 2009/10 growing seasons. A field experiment was conducted using a randomized complete block design that consisted of three planting patterns: (i) a uniform row spacing of 25 cm, and alternating wide–narrow row spacing of 40 and 20 cm tested as (ii) flat and (iii) furrow–ridge seedbeds. In addition, irrigation treatments of 90, 135 and 180 mm were used. The planting pattern, irrigation treatments and interactions between them significantly affected soil water content, stomatal conductance, leaf relative water content, leaf water potential and leaf water use efficiency. The soil water content, stomatal conductance, leaf relative water content, leaf water potential, grains/spike, thousand grain weight, leaf water use efficiency and yield were highest in the furrow–ridge seedbed planting pattern and increased with increasing irrigation (except for the leaf water use efficiency). The leaf water use efficiency in the 135 mm irrigation treatment was significantly greater than in the other treatments. In addition, soil water content, stomatal conductance, leaf relative water content, leaf water potential, grains/spike and thousand grain weight were positively correlated with leaf water use efficiency and yield of winter wheat. The interaction between the furrow–ridge seedbed planting pattern and 135 mm irrigation increased soil water content, leaf water indices, grains/spike, thousand grain weight, leaf water use efficiency and yield. These results indicated that a beneficial response occurred for wheat yield. The furrow–ridge seedbed planting pattern combined with 135 mm of irrigation improved the soil and leaf water status and could increase wheat yield while using less water.
