“…Sugar yield in T2, T3, T4, T5, T6, and T7 were 27, 12, 35, 45, 10, and 55% higher than that of the control, respectively. This suggested that severe water deficit from sugar accumulation growth stage to harvest would increase sugar yield significantly, which was in accordance with the study results of Haghverdi et al (2017).…”

Core Ideas Different growth stages of drip‐irrigated sugar beet can bear different water deficit level. The canopy development stage is the most water‐sensitive period of the sugar beet. Regulated deficit irrigation could increase beet yield and reduce the consumption of water resources in arid land. ABSTRACT The shortage of water resources promotes the development of water saving irrigation in arid land. Regulated deficit irrigation (RDI), as one of the water‐saving irrigation technologies through applying a certain amount of water stress to the crops to promote the distribution of the photosynthate of crops to the needs of the tissues and organs, can save water and may increase yield. Our study evaluated the effect of the RDI on the sugar beet (Beta vulgaris L. cv. Beta356). Seven irrigation treatments were applied based on the growth stages of sugar beet (canopy development, storage root development, and sugar accumulation) and water deficit levels (30, 50, and 70% of field capacity [FC]). The yield, quality, sugar yield, irrigation water use efficiency (IWUE), and agronomic physiological traits of sugar beet were evaluated. Moderate water deficit (50% of FC) during canopy development increased sugar yield by 27% compared with the control (70% of FC during the whole growth stages). Severe (30% of FC) water deficit increased sugar yield by 45% during storage root development, and by 55% during sugar accumulation. The RDI during canopy development and storage root development inhibited leaf growth but did not affect yield. Malondialdehyde content and relative conductivity increased significantly when soil water content dropped to the irrigation threshold levels (i.e., 30% and 50% of FC) before rehydration during canopy development. After rehydration, there were significant increases in peroxidase activity and proline content (indicators of antioxidant defense and osmotic stress). Our results indicated that RDI increased yield at 30% and 50% of FC during three growth stages (canopy development, storage root development, and sugar accumulation) of sugar beet, which reduced irrigation water requirements. RDI could be applied as a strategic action for crop sustainability and water saving in arid land.

“…The simulated evaporation for corn and soybean growth seasons was lower with the CC system than the NCC system, and the simulated plant transpiration was higher with the CC system than the NCC system (Figs 3, 5). The decreased evaporation during crop growth period can be attributed to the residue on the soil that remained after the wheat CC was terminated in mid‐April (Haghverdi, Yonts, Reichert, & Irmak, 2017; Qi & Helmers, 2010; Qi et al., 2011). These simulations are consistent with Qi et al.…”

The effect of cover crop (CC) on soil water balance and agricultural production is closely related to rainfall amount and distribution in rainfed cropping systems. This study used the root zone water quality model, RZWQM2, calibrated and validated with 4-yr field measurements to predict the effect of planting a winter wheat (Triticum aestivum L.) CC in a no-till rainfed corn (Zea mays L.)-soybean (Glycine max L.) rotation on soil water balance, crop yield, and grain water-use efficiency (WUE) in northeast Mississippi. Seasonal rainfall for 80 consecutive years was classified as 'wet,' 'normal,' and 'dry' years using frequency analysis, and the data sets matched chronologically to wheat, corn, and soybean growth periods were used as an input parameter in RZWQM2 simulations. During autumn and spring (early October to early April), the CC reduced deep drainage by 69 (11%), 53 (15%), and 51 mm (21%) in wet, normal, and dry years, respectively. Averaged across 40 yr, the CC decreased surface evaporation by 64 (32%) and 38 mm (24%) for corn and soybean growth periods, respectively. Wheat CC also improved soil water storage in early crop growth period during April-June in any of the three rainfall patterns. Regardless of rainfall patterns, the increase in WUE can be attributed to a decrease in evapotranspiration during cash crop period without sacrificing cash crop yield in the CC system. Introducing CC into cropping systems is beneficial to reduce annual deep drainage and evaporation while maintaining higher crop yields under different rainfall patterns.Abbreviations: CC, cover crop; ET, evapotranspiration; NCC, no cover crop; RZWQM2, root zone water quality model; WUE, water-use efficiency.

“…It is well known that soil water, C and N processes have very close interactions in soil and plant systems (Rhymes et al, 2016). Soil moisture, for example, can significantly affect plant growth and ecosystem productivity (Haghverdi et al, 2017), microbial activities (Singh et al, 2011), and greenhouse gas (GHG) emissions (Kumar et al, 2016). Moreover, in agro-ecosystems, C fixation by crops is closely coupled to water loss, which mainly occurs via leaf stomata.…”
