“…After 10-15 days of no water supply, the maize leaves at 120, 180, 240, and 260 kg N ha −1 treatment rates gradually began to curl from 10:00 a.m. to 5:00 p.m. daily, and the leaves were unfurled for the rest time of the day (Figure 2a). Several studies have shown that N deficiency exacerbated the sensitivity of stomata to drought [15,26]; however, we did not observe the leaf curling in the absence of N treatments, which was found under higher N treatment rates. This might be the case, as the application of N fertilizers increased plant water transpiration ( Figure 5), causing the plants treated with higher N treatment rates to enter the drought state earlier, which masked the increased resistance to drought stress with additional N treatments for the maize.…”

Inadequate water and nitrogen (N) supplies can limit the productivity of maize. Climate change will likely increase drought in many regions on a global scale. The determination of N fertilizer rates under field drought conditions will be critical toward the reduction of agricultural risk. For this study, drought-resistant/sensitive cultivars were selected as experimental samples. Our results revealed that drought stress reduced the relative water content (RWC) of leaves, which resulted in leaf curling, while decreasing photosynthesis levels and N accumulation. In contrast to those without N treatments, the application of N significantly increased grain yields by 26.8% during the wet year but increased only by 5.4% during the dry year. Under the same N levels, the reduction in yield caused by drought increased with the increased application of N. This was because the application of the N fertilizer translated to increase the leaf area and transpiration, exacerbated the soil water loss and induced a leaf curling state in maize, which had deleterious effects on photosynthesis and N absorption. During the dry year, the yields of drought-sensitive cultivars were even less than those without the application of N. Compared with those of drought-sensitive cultivars, the RWCs of drought-resistant cultivars decreased more rapidly, and they entered the state of leaf curling earlier. Thus, N fertilizer inputs should be reduced, and the extent of N fertilization for drought-sensitive cultivars should be reduced even further.

“…The grain quality of the winter wheat is likely be affected by nutritional quality, the farinograph parameter, varieties and the environment. This study revealed that irrigation treatment would maintain higher grain pro-tein, coarse starch and whiteness than rain-fed agriculture (p < 0.05), and the results showed that 90 mm treatment may improve flour quality, which is consistent with previous studies (Waraich et al, 2010). In contrast, Vida et al (2014) determined that flour quality is not closely related to the environment for winter durum wheat; however, throughout the winter wheat growing season in the North China Plain, adequate irrigation could increase the water use efficiency, in the decreasing rainfall conditions.…”

With the shortage of water resources in recent years, water has become an important factor that limits the photosynthetic capacity and grain quality of winter wheat in the North China Plain. The experiment was conducted in 2011-2014, and the design of the two-factor split-plot was adopted, with three irrigation levels (0, 90, and 180 mm) for the main plot and three planting patterns (single-single row, single-double row, doubledouble row) for the subplot. The chlorophyll content index, net photosynthetic rate, and dry matter weight of winter wheat at different growth stages were measured, and the quality parameters of the grain were also measured after the harvest. The result indicated that irrigation increased the chlorophyll content index, net photosynthetic rate, grain protein, coarse starch and whiteness, which were favourable for producing dry matter and for seed formation. The chlorophyll content index, net photosynthetic rate, dry matter weight and gluten index of double-double row were higher than those of single-single row. Therefore, the 90 mm irrigation combined with the double-double row planting pattern is a good agronomic practice for winter wheat production, and beneficial for the improvement of flour quality in the North China Plain.

“…Higher deficit irrigation (DI60) resulted 11.8% less 1000-grain weight as compared to full irrigation. Higher 1000-grain weight with full irrigation might be due to translocation of more photosynthates towards higher 1000-grain weight (Waraich et al, 2010). In other words plants having limited water supply produced lighter grains which might be due to less availability of nutrients from soil solution (Sarwar et al, 2010).…”
