“…The value of available soil zinc in the field was detected as 1.07 ± 0.06 before the experiment. Three kinds of high-quality, high-yielding rice varieties (i.e., HHZ, Huanghuangzhan; NJ9108, Nanjing-9108; ND9925, Nuodao-9925) cultivated locally were chosen as the tested plants, and the critical limit of zinc (Zn) in the soil for rice ranges from 0.80 to 0.85 μg/g ( Rahman et al, 2022 ). Two levels of basal Zn fertilizers (0 and 30 kg ha –1 ) were applied as ZnSO 4 ⋅H 2 O ha –1 (effective Zn content 34.5%) before rice transplantation (25 May 2020).…”

“…However, Zn deficiency is a widespread micronutrient disorder in rice, resulting in reduced rice grain yield and poor nutrition quality ( Fageria et al, 2002 ), continuous application of fertilizer and their low efficiency, especially N and P, and has caused environmental degradation ( Bindraban et al, 2020 ). These problems have posed a major threat to sustainable rice production and food security ( Rahman et al, 2022 ). Zn is one of the irreplaceable minor elements required for rice growth and other food crops ( Broadley et al, 2007 ).…”

Zinc is an essential minor element for rice growth and human health, which can also change the structure of the microorganisms. However, it remains unclear for the effects of zinc fertilizer on microbiome function in agricultural soils and crops. To solve this research gap, we investigated the relationship between improving rice (Oryza sativa L.) yield, Zn concentration, soil microbial community diversity, and function by the application of Zn fertilizer. The field trials included three rice varieties (Huanghuazhan, Nanjing9108, and Nuodao-9925) and two soil Zn levels (0 and 30 kg ha–1) in Jiangsu province, China. As a test, we studied the variety of soil bacterial composition, diversity, and function using 16S rRNA gene sequencing. The results showed that soil Zn application reduced the diversity of microbial community, but the bacterial network was more closely linked, and the metabolic function of bacterial community was improved, which increased the grain yield (17.34–19.52%) and enriched the Zn content of polished rice (1.40–20.05%). Specifically, redundancy analysis (RDA) and Mantel’s test results revealed soil total nitrogen (TN) was the primary driver that led to a community shift in the rice rhizosphere bacterial community, and soil organic carbon (SOC) was considered to have a strong influence on dominant phyla. Furthermore, network analysis indicated the most critical bacterial taxa were identified as Actinobacteria, Bacteroidetes, Proteobacteria, and Chloroflexi based on their topological roles of microorganisms. KEGG metabolic pathway prediction demonstrated that soil Zn application significantly (p < 0.05) improved lipid metabolism, amino acid metabolism, carbohydrate metabolism, and xenobiotic biodegradation. Overall, their positive effects were different among rice varieties, of which Nanjing-9108 (NJ9108) performed better. This study opens new avenues to deeply understand the plant and soil–microbe interactions by the application of fertilizer and further navigates the development of Zn-rich rice cultivation strategies.

“…The different critical values of Mn for soybeans could be attributed to the diversified properties of soils. A variation in sample sites can cause a significant change in nutrient-critical levels, as suggested by Rahman et al [45]. In the graphical technique, the plotting of calibration data is done as Bray's %yield versus soil test value.…”

Manganese (Mn) is an essential micronutrient for plants, which influences multiple physiological systems. Determination of the critical limit (CL) of Mn in the soil is necessary for Mn fertilizer application as this limit delineates the deficiency, optimum, and toxicity ranges of Mn. A pot experiment was performed in the winter season with 20 soils collected from three Agro-Ecological Zones (AEZs) of Bangladesh to determine the CL of Mn for soybean (Glycine max L.). Manganese was applied in soil @ 0, 1, 2, and 4 ppm, and the experiment was laid out in a factorial and completely randomized design with three replications. The CL of Mn was determined by the Cate-Nelson graphical and statistical approach and was found 3.60 and 3.55 µg g−1, respectively. Applying 1 µg g−1 Mn in soil significantly enhanced root and shoot weight, as well as seed yield of soybean compared to no Mn application. In field conditions, a significant positive response of soybean yield was found up to the CL of Mn. The findings of the study could help predict possible Mn deficiency in soil and soybean response to Mn fertilizer, which is important in decision-making for efficient fertilizer management practices to ensure the yield potential of soybeans.

“…It also interacts with other nutrients, such as Ferrum (Fe), and thus modulates their uptake and translocation in rice crops [14]. Deficiency of Zn is amongst the most commonly occurring micronutrient adversities, particularly in lowland paddy areas, and results in reduced growth, chlorosis, smaller leaves, and sterility as well as low grain yield and nutritional quality [15][16][17]. Moreover, the ubiquity of Zn-lacking soils worldwide has exposed one-third of the global population Zn deficiency [18], including children less than five years old, who become extremely vulnerable to the risks of various infectious diseases and stunted growth [19].…”

Understanding the agronomic interventions that ensure higher crop yields and minimize their chances of failure is critical for meeting global nutritional demands. Rice is a staple food crop that is prone to lodging risk, particularly when higher yields are desired. The potential role of a combined application of Zinc (Zn) and Silicon (Si) in determining the grain yield and lodging resistance has been rarely investigated under field conditions. Thus, field trials were carried out to evaluate the grain yield and lodging resistance of rice at two different locations i.e., Qionghai and Wuzhishan, under three levels of Zn (0, 40, and 80 kg ha−1) and Si (0, 120, and 240 kg ha−1). The results showed that Zn application at the rates of 40 and 80 kg ha−1 increased rice yield by 9% and 5% at Qionghai, and by 5% and 6% at Wuzhishan, respectively. The improved grain yield due to Zn application could be attributed to the increased panicles m−2, splikelets m−2, and aboveground biomass. Meanwhile, Zn failed to show any remarkable impact on stem and root lodging susceptibility. Conversely, no significant influence of applying Si on grain yield was observed, while its application at the rates of 120 and 240 kg Si ha−1 enhanced the stem and root lodging resistance (denoted by their respective safety factors, for stem (SFs) and for root (SFr) by 32% and 22% at Qionghai, and by 11% and 34% at Wuzhishan, respectively, compared to zero Si application. The improved lodging resistance in terms of SFs and SFr could be ascribed to the increased stem bending strength and anchorage strength, while self-weight moment of whole plant decreased. In summary, a beneficial role of Si in lodging resistance and Zn in yield enhancement were evidenced in the present study across the two sites. It can be concluded that by combining 40 kg Zn ha−1 with 120 kg Si ha−1, both grain yield and lodging resistance could be simultaneously improved in rice crops.
