“…It was reported by Varga et al. () that water supplies well below the optimum level led to a reduction in WUE as a consequence of stress effects. Above‐optimum water supplies could be expected to result in the opposite tendency.…”

“…Varga et al. () found that changes in the HI values of winter wheat cultivars were paralleled by changes in WUE and that simulated drought resulted in various extents of reduction in HI. In the present experiment, a close correlation was detected between WUE and HI irrespective of the phenophase in which the plants suffered water withholding.…”

In Central Europe, drought is the most important limiting factor for autumnsown cereals. Due to the decline in groundwater, it is a priority to use less waterdemanding forms of crop production. Water use efficiency (WUE) can only be increased if cultivars with satisfactory water management traits are grown, so that they can exploit the water reserves of the soil even if drought occurs during the vegetation. Water consumption and water use efficiency of winter wheat genotypes were investigated in a model experiment carried out in a climate-controlled glasshouse. The plants were grown either with optimum water supplies or with simulated drought in three phenophases, and measurements were made on the yield parameters, phenological traits and water use parameters of the plants. Substantial differences were observed between the water demands of the cultivars, and it was found that the later the phenophase in which drought was simulated, the greater the decline in water uptake. The analysis of WUE led to the conclusion that the WUE values of cultivars with short vegetation periods dropped to the greatest extent when water deficit was suffered at first node appearance, while cultivars with longer vegetation periods were more sensitive to drought during the heading and grain-filling stages.

“…), but have also emphasized the fact that changes in WUE are especially important if the water supply to the plants is limited (Varga et al. ). Evans and Sadler () reported that much additional information is required about actual crop evapotranspiration and water use levels when plants suffer different levels of stress during different growth stages.…”

The decline in the amount of water available to plants will lend growing importance to the dynamics of water uptake and to water use efficiency (WUE; g kg−1) in cereals. Water use properties were investigated in terms of the phenological and yield parameters of five winter wheat genotypes in a greenhouse experiment carried out in climate‐controlled chambers. The plants were grown either with optimum water supplies or with simulated drought in two phenophases, combined with different CO2 concentrations (ambient and enriched to 700 and 1000 ppm). Multivariate analysis showed that the CO2 concentration alone significantly influenced water use and water use efficiency but in combination with the cultivars, it also had a significant influence on the grain yield and in a combination with the water supply on the straw biomass, respectively. Higher CO2 concentration significantly reduced the water uptake and improved the WUE values in both the drought treatments. All three factors investigated were found to have a significant influence on the water consumption during the growing season, and the interaction between CO2 and the cultivar influenced WUE. The least change in WUE was detected for Bánkúti 1201 (1.35–1.86 g kg−1), while Mv Mambó, Plainsman V and Mv Toborzó formed a group responding similarly to various environmental effects (1.85–2.55 g kg−1; 1.57–2.34 g kg−1 and 1.45–2.24 g kg−1, respectively).

“…Petříková et al (2006) mention other benefits, as higher drought tolerance and better water use efficiency (WUE). Similarly Varga et al (2013) point out importance of cereals with higher WUE for current climatic conditions. Sorghum can find use for light soils and in dry areas (Bolsen et al 2003).…”

The influence of sweet sorghum crop stand arrangement on biomass and biogas production

The possibility of sweet sorghum cultivation with different inter-row distances (20, 50, 75 cm) was verified in small scale plots with 3 cultivars (Bovital, Goliath, Sucrosorgho). The maize cv. Atletico (rows 75 cm) was used as a control. The influence of row width and cultivar on fresh and dry biomass, methane and biogas production per area was statistically significant. The methane and biogas production was evaluated in laboratory, via fermentation in Oxi Top Control Merck bottles. Generally, sorghum was more productive than maize. The highest biogas production per hectare was found in case of 25 cm row spacing. Goliath was the most yielding cultivar (in all parameters). The experiment proved possibility to produce biomass from sorghum in narrow rows for biogas stations in the Czech Republic.
