“…Many studies have proposed that the most sensitive and effective evaluation parameters for the difference in Zn efficiency between different genotypes are as follows: dry matter production, visual symptoms of the severity of Zn deficiency, R/S ratio, Zn content, and Zn uptake efficiency. On the other hand, parameters that have poor correlation with Zn efficiency includes Zn concentration and differences of subcellular Zn compartmentation (Rengel and Graham, 1996;Cakmak et al, 1997Grewal et al, 1997;Khan et al, 1998;Erenoglu et al, 1999;Grewal and Williams, 1999;Hacisalihoglu and Kochian, 2003;Hacisalihoglu et al, 2004;Genc et al, 2006;Sadeghzadeh et al, 2009;Impa et al, 2013a).…”

All over the world, a common problem in the soil is the low content of available zinc (Zn), which is unevenly distributed and difficult to move. However, information on the foraging strategies of roots in response to heterogeneous Zn supply is still very limited. Few studies have analyzed the adaptability of maize inbred lines with different Zn efficiencies to different low Zn stress time lengths in maize. This study analyzed the effects of different time lengths of low Zn stress on various related traits in different inbred lines. In addition, morphological plasticity of roots and the response of Zn-related important gene iron-regulated transporter-like proteins (ZIPs) were studied via simulating the heterogeneity of Zn nutrition in the soil. In this report, when Zn deficiency stress duration was extended (from 14 to 21 days), under Zn-deficient supply (0.5 μM), Zn efficiency (ZE) based on shoot dry weight of Wu312 displayed no significant difference, and ZE for Ye478 was increased by 92.9%. Under longer-term Zn deficiency, shoot, and root dry weights of Ye478 were 6.5 and 2.1-fold higher than those of Wu312, respectively. Uneven Zn supply strongly inhibited the development of some root traits in the -Zn region. Difference in shoot dry weights between Wu312 and Ye478 was larger in T1 (1.97 times) than in T2 (1.53 times). Under heterogeneous condition of Zn supply, both the –Zn region and the +Zn region upregulated the expressions of ZmZIP3, ZmZIP4, ZmZIP5, ZmZIP7, and ZmZIP8 in the roots of two inbred lines. These results indicate that extended time length of low-Zn stress will enlarge the difference of multiple physiological traits, especially biomass, between Zn-sensitive and Zn-tolerant inbred lines. There were significant genotypic differences of root morphology in response to heterogeneous Zn supply. Compared with split-supply with +Zn/+Zn, the difference of above-ground biomass between Zn-sensitive and Zn-tolerant inbred lines under split-supply with –Zn/+Zn was higher. Under the condition of heterogeneous Zn supply, several ZmZIP genes may play important roles in tolerance to low Zn stress, which can provide a basis for further functional characterization.

“…Thus, Zn deficiency has been found responsible for yield reduction in rice (Fageria et al 2002;Quijano-Guerta et al 2002). Furthermore, a remarkable decrease in grain Zn concentration was recorded in cereals grown on soils suffering from Zn deficit (Cakmak et al 1997). Zinc-deficient grains led to a reduction in its bioavailability in humans and may contribute to Zn deficiency in susceptible human populations, particularly in countries where people mainly depend on cereal-based food (Cakmak 2008;Hussain et al 2012).…”

Due to the ability of weeds to deplete nutrients from the soil, crop plants become subjected to a complex of abiotic and biotic stresses. Thus, the interactive effects between one of the most important micronutrients, i.e., zinc (Zn) and some herbicides on weeds, rice yield and nutrient uptake were investigated. The experiment was carried out in a randomized complete block design in factorial arrangement using three replicates. Ten combinations of two Zn levels (without Zn, Zn−, and with Zn, Zn+) as well as four herbicides (halosulfuron-methyl, bentazon, azimsulfuron, pyrazosoulfuron-ethyl), and unweeded treatment were investigated. Findings clarified that application of halosulfuron-methyl herbicide whether with Zn− or Zn+ were the effective combinations for decreasing weed biomass. Halosulfuron-methyl and pyrazosoulfuron-ethyl had similar impact either with Zn− or with Zn+ resulted in minimum values of K uptake by weeds. The increases in grain yield ha −1 due to the application of halosulfuron-methyl, pyrazosoulfuron, azimsulfuron, and bentazon reached 13.4, 15.9, 21.3, and 24.8%, respectively, under Zn+ greater than Zn−. Halosulfuron-methyl x Zn+ was the promising interaction treatment for increasing P, K, and Zn uptakes by rice. Correlation coefficient showed that fertile panicle number, fertile grain number, rice N and K uptakes, weed biomass, and weed P uptake were the most closely associated traits with grain yield. Our study proved that there is a positive correlation between Zn and the applied herbicides in rice. Zn application alleviated the herbicidal pressure (abiotic stress) and decreased weed harmful impacts (biotic stress) on rice plants. Thus, it should be focused on the complementary effect between Zn and applied herbicides in breeding programs for generating new rice genotypes which are efficient in Zn utilization and tolerant to herbicides.

“…Sulfur (S) and zinc (Zn) deficiencies in soils are common nutrient problems throughout the world, with respect to both crop productivity and human nutrition. − Zinc deficiency is widespread and most common in calcareous and sandy soils. − Sulfur deficiency has become more prevalent in the past decades due to a decrease in incidental inputs through atmospheric deposition and fertilizers and an increase in crop S removals. Therefore, S- and Zn-containing fertilizers are applied to large agricultural areas to increase crop yields and food quality.…”

Acidification by oxidation of elemental sulfur (ES) can solubilize ZnO, providing slow release of both sulfur (S) and zinc (Zn) in soil. For this study, a new granular fertilizer with ES and ZnO was produced and evaluated. The effect of incorporating microorganisms or a carbon source in the granule was also evaluated. Four granulated ES-Zn fertilizers with and without S-oxidizing microorganisms, a commercial ES pastille, ZnSO, and ZnO were applied to the center of Petri dishes containing two contrasting pH soils. Soil pH, CaCl-extractable S and Zn, and remaining ES were evaluated at 30 and 60 days in two soil sections (0-5 and 5-9 mm from the fertilizer application site). A visualization test was performed to evaluate Zn diffusion over time. A significant pH decrease was observed in the acidic soil for all ES-Zn fertilizer treatments and in the alkaline soil for the Acidithiobacillus thiooxidans-inoculated treatment only. In agreement with Zn visualization tests, extractable-Zn concentrations were higher from the point of application in the acidic (62.9 mg dm) compared to the alkaline soil (5.5 mg dm). Elemental S oxidation was greater in the acidic soil (20.9%) than slightly alkaline soil (12%). The ES-Zn granular fertilizers increased S and Zn concentrations in soil and can provide a strategically slow release of nutrients to the soil.
