“…This indicated that NS and MS practices received adequate soil moisture as compared to SS (Figure 2). Similarly, Zhang et al 42 and Oliver et al 43 also observed that the above-ground biomass was decreased by 6−17% under the NS practice when compared to that under soil moisture stress-based irrigation. Furthermore, the aboveground biomass was influenced by the NAR.…”

Alternate wetting and drying irrigation practice in rice cultivation can save a significant amount of irrigation water. It involves irrigating rice fields alternately based on an irrigation triggering criterion and possibly influences the soil–plant–water system. In this study, field experiments were carried out for 3 years with three levels of soil matric potential heads (SMPHs) (no soil water stress: conventional irrigation, NS; 400 cm: mild soil water stress, MS; and 750 cm: severe soil water stress, SS) along with three levels of nitrogen (150 kg N/ha: high nitrogen, HN; 120 kg N/ha: medium nitrogen, and MN; 60 kg N/ha: low nitrogen, LN), and they were replicated three times. The daily ponding water depth and SMPHs at 10, 40, and 70 cm soil depths and agronomical parameters (plant height, number of tillers, biomass, and grain yield) were measured at regular intervals during the field experiments. The field data were used to assess water and nutrient dynamics and determine the crop production function. The grain yield under MS was almost similar to that under NS, but it was reduced by 9% under the SS practice. On the other hand, the MS and SS practices reduced 23 and 27% of the total available water depth, 6 and 15% of N uptake, 5 and 15% of P uptake, and 7 and 18% of K uptake, respectively, compared to NS. Furthermore, the effect of lesser uptake of water and nutrients on the crop yield was not significant in the case of MS. The MS + MN practice reduces the irrigation water without any significant reduction in grain yield, and this combination of water and nutrient management will be more appropriate for sustainable rice production.

“…AWD is the most widely used water-saving irrigation technology in rice production, with obvious watersaving benefits (H. Zhang, Zhang, Yang, Zhang, & Wang, 2008). This model has been adopted in Hubei, Anhui, Zhejiang, and other provinces in southern China as well as in the north (S. H. Ma et al, 2021;Yao et al, 2014;H. L. Zhang et al, 2018).…”

The conflict between rice production and water scarcity is becoming more pronounced. Therefore, the advancement of water‐saving rice cultivation is crucial in guaranteeing both food and ecological security. This study provides a summary of the development and characteristics of various water‐saving cultivation techniques for rice, including alternate wetting and drying irrigation, wet irrigation, controlled irrigation, the system of rice intensification, direct seeding rice, and dry cultivation of rice (DCR). We also introduce the varietal characteristics of upland rice, aerobic rice, water‐saving and drought‐resistant rice, and DCR. We summarize the impact of different water‐saving cultivation models on yield and quality and regulatory measures, and propose challenges and strategies for the development of water‐saving cultivation of rice in the future. We hope to provide a reference for promoting the development of rice water‐saving cultivation and dry farming agriculture.

“…According to some studies, upland rice cultivation or alternating dry and wet cultivation enhances the sensory and nutritional qualities of rice. ( Norton et al., 2017 ; Zhang et al., 2020 ; Song et al., 2021 ). However, some researchers have found that water-saving irrigation increases the chalkiness degree and amylose content of grains, thereby negatively affecting rice quality ( Graham-Acquaah et al., 2019 ).…”

IntroductionApproximately 50% of irrigation water is saved during drip-irrigation of rice, which has tremendous potential for water-saving agriculture, particularly in areas where water resources are scarce. However, the grain yield and quality of drip-irrigated rice are adversely affected.MethodsIn this study, we investigated the effects of different irrigation strategies on the grain yield and quality of drip-irrigated rice using field experiments. Four irrigation treatments were studied: whole growing season flooding (FI), whole growing season normal drip irrigation (DI, soil relative moisture (RSM) was maintained in the range of 90-100%), pre-anthesis drip irrigation and post-anthesis water stress (SAF, the RSM was maintained in the range of 80-90% after anthesis), pre-anthesis drip irrigation, and post-anthesis flooding (FAF).ResultsThe results showed that grain yield, harvest index, seed setting rate and 1000 grain weight in DI and SAF were significantly lower than in FI and FAF. These parameters were not significantly different between FI and FAF but were significantly greater in DI than in SAF. Compared with FI and FAF, the source capacity, source activity time, and sink activity of DI and SAF decreased, and the sink-source difference increased. The sink-source difference had a significant negative correlation with rice yield and 1000 grain weight. The activities of ADP-glucose pyrophosphorylase, starch branching enzyme, and amylopectin content in grains in the middle panicles of FAF were significantly higher than those of DI and SAF. SAF resulted in increased amylose/amylopectin ratio and total protein content in grains but decreased proportion of glutenin in total protein. Irrigation after anthesis of drip-irrigated rice narrowed the difference between sink sources in rice plants, increased the grain yield and harvest index by 29.2% and 11%, respectively, compared to DI, increased water productivity by 19% compared to FI, and improved the grain quality of drip-irrigated rice.DiscussionThis study highlights that post-anthesis sufficient irrigation of drip-irrigated rice plays a positive role in maintaining the source-sink balance. This study serves as a foundation for the development of more effective rice farming methods that conserve water, while increasing the grain yield and quality of drip-irrigated rice.
