“…Water stress negatively affects the growth and productivity of crops (Ahuja et al 2010;Shekoofa and Sinclair 2018). Physiological functioning in rice plants (Guimarães et al 2013;Yang et al 2019;Abdou et al 2021) viz root length density, root moisture extraction, the rate of apical development, canopy size, leaf elongation rate, leaf rolling, transpiration rate, RWC, biomass production, spikelet number, spikelet sterility, panicle development, grain size, and grain yield (Palanog et al 2014;Kruzhilin et al 2016;Yang et al 2019) may be drastically reduced due to water stress, especially if it occurs during vegetative or reproductive stages of rice, depending upon the stress severity and cultivar tolerance. In recent years, the trickle irrigation system has been spread out more intensely, not only for enhancing water productivity but also for increasing crop production (Geerts and Raes 2009).…”

Inoculating rice plants by plant growth promoting rhizobacteria (PGPR) may be used as a practical and eco-friendly approach to sustain the growth and yield of drought stressed rice plants. The effect of rice inoculation using plant growth hormones was investigated under drip full irrigation (FI; 100% of evapotranspiration (ETc), and deficit irrigation (DI; 80% of ETc) on growth, physiological responses, yields and water productivities under saline soil (ECe = 6.87 dS m−1) for 2017 and 2018 seasons. Growth (i.e. shoot length and shoot dry weight), leaf photosynthetic pigments (chlorophyll ‘a’ and chlorophyll ‘b’ content), air–canopy temperature (Tc–Ta), membrane stability index (MSI%), and relative water content, (RWC%) chlorophyll fluorescence (Fv/Fm) stomatal conductance (gs), total phenols, peroxidase (PO), polyphenol oxidase (PPO), nitrogen contents and water productivities (grain water productivity; G-WP and straw water productivity; S-WP) were positively affected and significantly (p < 0.05) differed in two seasons in response to the applied PGPR treatments. The highest yields (3.35 and 6.7 t ha−1 for grain and straw yields) as the average for both years were recorded under full irrigation and plants inoculated by PGPR. The results indicated that under water scarcity, application of (I80 + PGPR) treatment was found to be favorable to save 20% of the applied irrigation water, to produce not only the same yields, approximately, but also to save more water as compared to I100%.

The results of studies on the influence of water or nutrient regimes of the soil on the formation of the root system of rice when watering drip system. Thus, while maintaining the water regime of the soil not less than 80% of HB in the 0.6 m layer, the root mass was in the three years in the 0.4 m layer 4.96, and 0.6 m - 5.64 t/ha. In the variant where soil moisture was maintained at least 80% HB and the depth of soil wetting until the end of the tillering phase by 0.4 with a further decrease to 0.6 m, the plants differed in maximum foliage and habitus, which contributed to an increase in the root mass of aerobic rice in the layer of 0.4 m to 5.40, and in the layer of 0.6 m 6.14 t/ha. In the variant of the water regime of the soil with a moisture content of not less than 80% HB from sowing to the end of the tillering phase in a layer of 0.4 m, followed by a decrease to 0.6 m, and from wax to full ripeness of grain not less than 70% HB the volume of roots compared to the second option for three years in a layer of 0.4 m became less by 0.18 t/ha, and in a layer of 0.6 0.20 t/ha, but more than the first in a layer of 0.4 m by 0.26 m and 0.6 m 0.30 t/ha. Also had a great influence on the root system of aerobic rice. Thus, its lowest value, 5.46 t/ha for the three years, was formed when making N95P62K75 (5 t/ha). Making N114P74K90 (6 t/ha) increased root weight by 0.48 t/ha regarding the N95P62K75 dose (5 t/ha), but was below making N137P90K108 (7 t/ha) 0.60 t/ha. In the result of the conducted researches it was established that maximum yield of grain (of 6.95 t/ha) was obtained in variant water regime of soil 80% of NV in layers of 0.4 and 0.6 m, making N137P90K108 (7 t/ha). The minimum yield, 4.88 t/ha, was obtained in the variant of soil water regime of 80% of NV in a layer of 0.6 m with the introduction of N95P62K75 (5 t/ha).

“…In this case of drought stress, the root water uptake of rice is affected by the root response, which is highly dependent on the crop genotype, period, and density of stress [46,47]. The reduction in growth and yield of rice caused by water stress may be attributed to the decrease in SWC, resulting in lower water and nutrient uptake by roots, causing a reduction in cell deviation, a cell enlargement decreases in the leaf area [48], stomatal closure, and a reduction in photosynthetic activity [49][50][51][52].…”

Root distribution during rice cultivation is a governing factor that considerably affects soil water content (SWC) and root water uptake (RWU). In this study, the effects of activating root growth (using growth function) and assigning a constant average root depth (no growth during simulation) on SWC and RWU for rice cultivation under four deficit drip irrigation treatments (T90, T80, T70, and T60) were compared in the HYDRUS-2D/3D model version 3.03. A secondary objective was to investigate the effect of applied deficit irrigation treatments on grain yield, irrigation water use efficiency (IWUE), and growth traits of rice. The simulated DI system was designed to reflect a representative field experiment implemented in El-Fayoum Governorate, Egypt, during two successive seasons during 2017 and 2018. The deficit treatments (T90, T80, T70, and T60) used in the current study represent scenarios at which the first irrigation event was applied when the pre-irrigation average SWC within the upper 60 cm of soil depth was equal to 90%, 80%, 70%, and 60% of plant-available water, respectively. Simulation results showed that as water deficiency increased, SWC in the simulation domain decreased, and thereby, RWU decreased. The average SWC within the root zone during rice-growing season under different deficit treatments was slightly higher when activating root growth function than when considering constant average root depth. Cumulative RWU fluxes for the case of no growth were slightly higher than for the case of root growth function for T90, T80, and T70 accounting for 1289.50, 1179.30, and 1073.10 cm2, respectively. Average SWC during the growth season (24 h after the first irrigation event, mid-season, and 24 h after the last irrigation event) between the two cases of root growth was strongly correlated for T90, T80, T70, and T60, where r2 equaled 0.918, 0.902, 0.892, and 0.876, respectively. ANOVA test showed that there was no significant difference for SWC between treatments for the case of assigning root growth function while the difference in SWC among treatments was significant for the case of the constant average root depth, where p-values equaled 0.0893 and 0.0433, respectively. Experimental results showed that as water deficiency decreased, IWUE increased. IWUE equaled 1.65, 1.58, 1.31, and 1.21 kg m−3 for T90, T80, T70, and T60, respectively. Moreover, higher grain yield and growth traits of rice (plant height, tillers number plant−1, panicles length, panicle weight, and grain number panicles−1) were obtained corresponding to T90 as compared with other treatments. Activating the root growth module in HYDRUS simulations can lead to more precise simulation results for specific dates within different growth stages. Therefore, the root growth module is a powerful tool for accurately investigating the change in SWC during simulation. Users of older versions of HYDRUS-2D/3D (version 2.05 and earlier) should consider the limitations of these versions for irrigation scheduling.
