Evaluation of irrigation scheduling and yield response for wheat cultivars using the AquaCrop model in an arid climate

et al. 2021

Yield, soil water balance components and evapotranspiration-based water productivity (WPET) of three winter wheat cultivars were investigated using AquaCrop model under arid conditions in Shiraz, Iran, for two consecutive years. The irrigation treatments were non-stressed (I1) and post-anthesis water stress (I2) with three wheat cultivars. Evaluation of the model was performed using the coefficient of root mean squared error (RMSE) and normalized RMSE and R2. The AquaCrop model performed well in simulating grain yield and final biomass production with R2 > 0.90, RMSE and normalized RMSE values less than 10. The I1 treatment resulted in higher grain yield and biomass productivity than I2 treatment. The I2 irrigation resulted in yield reduction of 21 and 24% in 2006–2007 and 2007–2008 growing seasons, respectively, as compared with I2. Using the measured grain yield and AquaCrop-simulated water balance, the amount of WPET varied from 0.68 to 0.95 kg m−3. The AquaCrop model was able to predict winter wheat biomass and yield production with a good accuracy in arid conditions of this study and especially its ability to simulate these variables for different wheat cultivars' was notable. The AquaCrop model can be used to explore management scenarios to improve wheat water management in the study region.

“…The amount of WP IþP varied from 0.45 to 0.80 kg m À3 , which are lower than the values reported in the literature. Zhao et al (2020) reported a range of WP I from 0.78 to 2.29 kgm À3 for wheat. Xu et al (2016) showed that the maximum WPs were obtained when the wheat was irrigated at the heading and post anthesis stages.…”

“…Compared to YN, JM, and LX with lower yields both had higher CP from planting to jointing and from jointing to anthesis but a lower CP from anthesis to maturity stages (Figure 5 and Table 1). The significant increases in CP from anthesis to maturity stages of JM and LX in the following year may be due to the monthly precipitation fluctuations (Supplementary Figure 1) because the water requirement of winter wheat can be influenced by interannual precipitation variability (Zhao et al, 2020). A previous study showed that wheat yield and WUE in the water shortage area could increase by increasing post-anthesis water use amount and ratio via a reasonable irrigation strategy (Xu et al, 2018).…”

“…Improving water use efficiency (WUE) is a crucial approach for food security in regions such as the 3HP, where water shortage is a major challenge for agriculture (Brauman et al, 2013;Rashid et al, 2019). Therefore, reasonable irrigation strategies have been proposed (i.e., regulating irrigation frequency and timing, applying deficit irrigation, and supplemental irrigation) for increasing WUE and maintaining high wheat production (Wang, 2017;Meena et al, 2019a;Zhao et al, 2020). However, studies have shown that renewing varieties is an effective way to increase yield and WUE (Faralli et al, 2019;Meena et al, 2019b), and it is necessary to study the physiological characteristics of wheat varieties with high yield and high WUE.…”

Selecting high-yielding wheat varieties for cultivation can effectively increase water use efficiency (WUE) in the Huang–Huai–Hai Plain, where is threatened by increasing water shortages. To further identify the difference in water use and its relationship with root morphology and senescence characteristics, wheat varieties with different yield potentials—Yannong 1212 (YN), Jimai 22 (JM), and Liangxing 99 (LX)—were studied in a high-yielding wheat field. The water consumption percentage (CP) in YN decreased from planting to anthesis; however, crop evapotranspiration and CP increased from anthesis to maturity compared with JM and LX. In YN, a higher soil water consumption from anthesis to maturity in the 0–100 cm soil layer was partly attributed to the greater root weight density in the 20–60 cm soil layer. In topsoil (0–40 cm), root length density, root surface area density, and root diameter at 20 days after anthesis, root superoxide dismutase activity, and root triphenyl tetrazolium chloride reduction activity during mid grain filling stage were higher in YN than in JM and LX. YN had the highest grain yields of 9,840 and 11,462 kg ha–1 and increased grain yield and WUE by 12.0 and 8.4%, respectively, as compared with JM, and by 30.3 and 21.3%, respectively, as compared with LX. Ensuring more soil water extraction post-anthesis by increasing roots in the 20–60 cm soil profile, improving root morphology traits, and alleviating root senescence in the topsoil during mid-grain filling stage will assist in selecting wheat varieties with high yield and WUE.

“…In certain developmental periods of crops, water limited irrigation triggers a compensatory promotion of growth after release of the drought stress, which simultaneously improves water use efficiency, yield, and quality of crops ( Araya et al, 2019 ). An efficient rehydration compensation is dependent on a good balancing between “self-protection” of crops upon drought stress and “compensation” after rehydration treatment ( Zhao et al, 2020 ). Consequently, it is crucial to clarify the physiological changes and molecular mechanisms associated with both water deficit and rehydration in wheat ( Lopes et al, 2012 ; Song et al, 2017 ).…”

Rehydration Compensation of Winter Wheat Is Mediated by Hormone Metabolism and De-Peroxidative Activities Under Field Conditions

Water deficit and rehydration frequently occur during wheat cultivation. Previous investigations focused on the water deficit and many drought-responsive genes have been identified in winter wheat. However, the hormone-related metabolic responses and de-peroxidative activities associated with rehydration are largely unknown. In this study, leaves of two winter wheat cultivars, “Hengguan35” (HG, drought-tolerant cultivar) and “Shinong086” (SN, drought-sensitive cultivar), were used to investigate water deficit and the post-rehydration process. Rehydration significantly promoted wheat growth and postponed spike development. Quantifications of antioxidant enzymes, osmotic stress-related substances, and phytohormones revealed that rehydration alleviated the peroxidation and osmotic stress caused by water deficit in both cultivars. The wheat cultivar HG showed a better rehydration-compensation phenotype than SN. Phytohormones, including abscisic acid, gibberellin (GA), jasmonic acid (JA), and salicylic acid (SA), were detected using high-performance liquid chromatography and shown to be responsible for the rehydration process. A transcriptome analysis showed that differentially expressed genes related to rehydration were enriched in hormone metabolism- and de-peroxidative stress-related pathways. Suppression of genes associated with abscisic acid signaling transduction were much stronger in HG than in SN upon rehydration treatment. HG also kept a more balanced expression of genes involved in reactive oxygen species pathway than SN. In conclusion, we clarified the hormonal changes and transcriptional profiles of drought-resistant and -sensitive winter wheat cultivars in response to drought and rehydration, and we provided insights into the molecular processes involved in rehydration compensation.
