“…However, few studies reported reduced grain yield (by 6−33%) under soil moisture stressbased irrigation. 9,12,13 Furthermore, the increase in NAR increases chlorophyll, crop photosynthesis, promotes the number of a tiller and above-ground biomass, and increases the grain yield under HN as compared to that under LN.…”

However, Zhang et al 13 applied 2−3 cm of PWD when the SMPH reaches 250 cm at 15−20 cm soil depth and observed that the AWD practice can save 18% of total applied water with a decrease in grain yield by 10% as compared to the CI practice. Many other studies also observed that increasing the SMPH two times (at 15−20 cm soil depth) will save the total applied water by 20−55% and decrease the grain yield by 8− 23%.…”

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.

“…The third most limiting nutrient for the growth of plants is iron (Fe) [27] that plays a vital role in plant growth and food production [28] and, as a cofactor for approximately 140 enzymes, can improve photosynthesis and assimilates transportation to sinks and eventually amends grain yield and oil content under drought stress [20,29,30]. The nano iron chelates fertilizers application is highly efficient due to excessive chemical fertilizers and the resulting contamination of groundwater and soil salinization [31].…”

Background: Application nano iron chelate and AMF fertilizer can increase plants' tolerance against water deficit stress. The main objectives of the current study were to investigate the effect of arbuscular mycorrhizal fungi (AMF) and nano iron chelate fertilizer under drought stress on grain yield, leaf chlorophyll contents, root colonization, oil percentage, and fatty acids profile of Lallemantia species. The experiment was carried out as a factorial based on a complete randomized block design consisting of three factors of irrigation levels of 90 (I90), 60 (I60), and 30% (I30) depletion of available soil water (ASW)), fertilizer levels of control (no fertilizer), AMF inoculation, and nano iron chelate, and plant species of Lallemantia (L. iberica and L. royleana) at the Research Farm of College of Agriculture, Shahed University, Tehran, Iran, in 2018/2019. Results: The results showed that increasing water deficit stress significantly decreased the above traits while applying nano iron and AMF fertilizers significantly increased them across water treatments. AMF fertilizer inoculation significantly improved both species yield. Higher root colonization by AMF inoculation enhanced seed oil and fatty acids (palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, arachidic acid, and Eicosenoic acid). In contrast, applying nano iron chelate by increasing chlorophyll content in any irrigation regime could enhance seed oil and some fatty acids such as palmitoleic acid. Conclusions: Water deficit stress and application of fertilizers had different effects on both species. L. iberica, compared to L. royleana, had the most tolerance to water deficit stress and the highest dependence on AMF inoculation. Overall, these results demonstrated that the application of AMF could improve major features of Lallemantia species under deficit irrigation conditions, especially at the I60 irrigation level.

“…PFMC helps to save irrigation water and fertilizer, promote rice plant growth, improve ecological and economic benefits, and facilitate high grain yield when under appropriate water and fertilizer management (Fan et al, 2005;Li et al, 2007;Liang et al, 1999;Liu et al, 2003;Lu & Wu, 2002;Tian, Lu, Fan, Li, & Kuzyakov, 2013;Wu et al, 2001). However, there have also been some observations that the PFMC reduced, rather than increased, grain yield when compared with the CF (Cheng, Zhang, Zhao, Yao, & Wang, 2003;Li et al, 2017Li et al, , 2007Xu, Zhang, Lam, Wang, & Yang, 2007;Zhang et al, 2019;Zhang, Xue, Wang, Yang, & Zhang, 2009). Obviously, data on the effect of PFMC on yield would benefit from clarification.…”

An important challenge facing rice production in China is to solve the problem of declining freshwater supply without affecting grain yield and quality. The purpose of this study was to investigate the effects of cultivation methods on the grain‐filling and chalk grains of Zhonghan 3 (Japonica) upland rice and Wuxiangjing 99–8 (Japonica) paddy rice. Both cultivars were cultivated in fields under three cultivation methods: continuous flooding (CF) as a control, bare dry cultivation (BC), and plastic film mulching dry cultivation (PFMC). Compared with CF, the yield of the upland rice decreased significantly, and the yield of paddy rice did not differ significantly under PFMC. The yields of both cultivars decreased significantly under BC. Superior and inferior grains of the two cultivars under PFMC had a greater mean grain‐filling rate (G) and a shorter active grain‐filling time (D). Under PFMC, the two cultivars had a higher export translocation rate of the matter from the stem and sheath and a slower decrease of the chlorophyll content in the flag leaves and nitrogen content in the plants after heading. Upland rice had a higher grain weight, and paddy rice had a lower grain weight compared to CF. The chalkiness of the two cultivars was significantly lower under dry cultivation than under CF. The correlation analysis showed that the percentage of chalky grains was negatively correlated with G and positively correlated with D, indicating that dry cultivation could improve the grain‐filling rate and appearance quality of the two cultivars.
