“…These findings acknowledged with results obtained by Simarmata et al (2016).Application of ZnO NPs improved the yield in rice over the control and ZnSO 4 application which maybe because of the delivery of Zn nutrient through ZnO NPs in the right dose and right size aided in enhancing the growth and yield attributes of rice crop. Similar findings were reported by Kheyri et al(2019).…”

“…Among the nutrient managements, the highest productive tillers were recorded with 75% RDF+ fortified rice residue compost + ZnO NPs(SP+FS) and lowest with control (100% RDF) with 417 and 290, respectively.TPR with 75% RDF+ fortified rice residue compost + ZnO NPs (SP+FS) recorded the highest productive tillers than other combinations (Ishfaq, 2020). Nano zinc application increased the Zn uptake by rice which played a significant role in metabolic, physiological and biochemical activities which aided in producing the higher number of productive tillers (Kheyri et al., 2019).…”

This study was conducted during the kharif, 2020 at ICAR-Perunthalaivar Kamaraj Krishi Vigyan Kendra, Puducherry, India aimed to examine the effect of fortified in situ rice residue compost, zinc nano fertilizer on the growth and yield of rice under rice cultivation methods. The experiment was conducted in a split plot design; 3mainplots (TPR, DSR and AR) and eight subplots (fortified manures and nano zinc particles) with three replications. The results revealed that the TPRsignificantly improved tillers, LAI, productive tillers, panicle weight, grain and straw yield, zinc content and uptake and it was statistically on par with DSRand superior over AR. Nutrient management, fortified manure + ZnO NPs (SP+FS) significantly registered higher growth and yield attributes, Zn content and uptake of rice over to ZnO seed priming alone, ZnSO4 and control. The PGPM, humic acid and seaweed extract fortified organic manures either FYM or rice residue compost, nano zinc as seed priming and foliar spray under TPR or DSR have the potential to maximize rice production without foregoing soil sustainability

“…Zinc can activate flavour enzymes, decomposing sugar, fat, and protein in rice. Flavour substances such as fatty acids, aldehydes, and ketones are increased, and the overall taste of rice is improved [32,33]. The data in our study showed that the appropriate amount of basal application of ZnO NPs increased the rate of the brown rice, milled rice and head rice, improving the rice processing quality.…”

Zinc oxide nanoparticles (ZnO NPs) have been applied widely in agriculture, and many studies were conducted to evaluate the effect of ZnO NPs on plant growth. So far, few studies have been investigated with regard to the potential effect of ZnO NPs on cereal yield formation or Zn content in grains. Herein, we used a pot experiment, which was conducted involving five dosages of Zn (0.3, 0.6, 1.2, 2.4, and 4.8 g Zn pot−1), to evaluate the impacts which ZnO NPs made in rice yield, dry matter accumulation, rice quality and grain Zn contents. The results demonstrated that ZnO NPs increased the production of grain, dry matter accumulation and particulate Zn content. Compared with control treatment, ZnO NPs application presented higher rice yield with more panicle number (4.83–13.14%), spikelets per panicle (4.81–10.69%), 1000-grain weight (3.82–6.62%) and filled grain rate (0.28–2.36%). Additionally, the dry jointing, heading and mature periods, LAI, SPAD values, and photosynthetic potentials of ZnO NPs were all significantly higher relative to treatment without ZnO NPs. The more photosynthetic substances and higher dry matter accumulated in the whole rice growing stage resulted in higher rice grain yield. Furthermore, ZnO NPs increased brown rice rate, milled rice rate, head rice rate, chalkiness size, chalkiness grain rate, chalkiness degree, amylose content and protein content, improving rice processing and appearance qualities. For the Zn nutrition in rice grain, ZnO NPs application significantly increased the Zn content of edible polished rice and promoted the relocation of Zn from the aleurone layer. This study effectively demonstrated that ZnO NPs could be a potential high-performed fertiliser for enhancing rice yield and quality.

“…The beneficial effect of SiO 2 NPs on grain yield may be ascribed to enhancing panicle fertility during grain filling [ 39 ]. Moreover, it is suggested that supplementation of Si in the nano form resulted in elevating Zn content in plant tissues, which lead to enhanced productivity [ 40 ]. It is worth noting that Si causes amendments of C/N homeostasis by remobilization of amino acids manifested by an enhancement of N needs during grain development [ 41 ].…”

Application of Silica Nanoparticles for Improving Growth, Yield, and Enzymatic Antioxidant for the Hybrid Rice EHR1 Growing under Water Regime Conditions

The current study was designed to assess the effect of different concentrations of silica oxide nanoparticles (SiO2NPs) (0, 30, 60, and 90 ppm) as foliar applications under three irrigation regimes i.e., irrigation every 3 days (IR3, control), irrigation every 6 days (IR6), and irrigation every 9 days (IR9) on growth, yield and certain metabolites of rice (Oryza sativa L. cv. EHR1). To achieve such a goal, 2 field experiments were conducted during the 2018 and 2019 seasons at the Experimental Farm of Rice Research and Training Center (RRTC), Sakha Agricultural Station, Kafr El-sheik, Egypt. Firstly, the as-prepared nanoparticles of SiO2 were prepared from useless materials (RHs) which are considered as one of the bio burdens on the environment via treating with HCl and followed by drying and calcination. Consequently, the synthesis was examined by making use of advanced tools such as X-ray diffraction (XRD), transmission electron microscopy (TEM), dynamic light scattering (DLS) for illustrating the hydrodynamic particle size of SiO2NPs and scanning electron microscopy (SEM). The nanoparticles were formed with nearly spherical shape and small size. The results indicated that leaf area index, dry matter production, the number of panicles/m2, the number of filled grains/ panicles, 1000 grain weight, grain yield, and biological yield as well as chlorophyll content have witnessed a significant increase under irrigated application every 3 and 6 days. Whilst a prolonged irrigation regime up to 9 days recorded a remarkable decline in the aforementioned characteristics except for the number of unfilled grains/panicle which increased considerably in both seasons. On the other hand, proline concentration and the activity of the antioxidant enzymes were increased in both irrigated treatments every 6 and 9 days compared with control treatment (irrigation every 3 days). The foliar supplementations of (SiO2NPs) contributed to ameliorating all the aforementioned characteristics progressively up to the dosage of 90 ppm compared to control treatment (no Si/NPS application) in both seasons. Invariably, growth and yield parameters in water-stressed plants treated with SiO2NPs were higher than those in water-stressed plants without SiO2NPs addition. Based on that, it could be concluded that the foliar application of SiO2NPs can mitigate the adverse effect of water stress on rice plants.
