“…In addition, Zn-EDTA (ethylenediaminetetraacetic acid) is also being recommended due to its efficiency of Zn availability for the plant (Rehman et al, 2012). However, varied responses of crops to the Zn fertilizers have been reported, depending on the source, application time, methods (Rehman et al, 2012;Takrattanasaran et al, 2013) as well as soil chemical properties, which are also influenced by water management (Rehman et al, 2012).…”

Zinc (Zn) deficiency and water scarcity are major challenges in rice (Oryza sativa L.) under an intensive rice production system. This study aims to investigate the impact of water-saving management and different Zn fertilization source (ZnSO 4 and Zn-EDTA) regimes on grain yield and Zn accumulation in rice grain. Different water managements, continuous flooding (CF), and alternate wetting and drying (AWD) were applied during the rice growing season. Compared with CF, the AWD regime significantly increased grain yield and Zn concentrations in both brown rice and polished rice. Grain yield of genotypes (Nipponbare and Jiaxing27), on the average, was increased by 11.4%, and grain Zn concentration by 3.9% when compared with those under a CF regime. Zn fertilization significantly increased Zn density in polished rice, with a more pronounced effect of ZnSO 4 being observed as compared with Zn-EDTA, especially under an AWD regime. Decreased phytic acid content and molar ratio of phytic acid to Zn were also noted in rice grains with Zn fertilization. The above results demonstrated that water management of AWD combined with ZnSO 4 fertilization was an effective agricultural practice to elevate grain yield and increase Zn accumulation and bioavailability in rice grains.

“…According to the Office of Agricultural Economics (OAE), Thailand produced approximately 35 million tons of cassava, 50 thousand tons of soybeans, and 35 thousand tons of peanuts in 2021 ( OAE, 2021 ). Zinc insufficiency is a common issue in Thailand, where calcareous soils are widely utilized for cultivating staple crops ( Takrattanasaran et al, 2010 ; Chittamart et al, 2016 ). These soils have less bioavailable zinc because some of the zinc is adsorbed on the calcium carbonate in the calcareous soils ( Takrattanasaran et al, 2013 ).…”

These soils have less bioavailable zinc because some of the zinc is adsorbed on the calcium carbonate in the calcareous soils ( Takrattanasaran et al, 2013 ). In addition, Zn deficiency in crops is caused by a combination of factors, including low Zn levels in the soil, inadequate Zn solubility in the soil, and Zn conversion to an insoluble form ( Sharma et al, 2013 ).…”

Zinc-solubilizing rhizobacteria can convert insoluble zinc to an accessible form and increase Zn bioavailability in soil, which help mitigate Zn deficiency in crops. In this work, 121 bacterial isolates were isolated from the rhizosphere soils of peanuts, sweet potatoes, and cassava, and their capability to solubilize Zn was evaluated using Bunt and Rovira’s agar containing 0.1% ZnO and ZnCO3. Among these isolates, six showed high Zn solubilization efficiencies ranging from 1.32 to 2.84 and 1.93 to 2.27 on the medium supplemented with 0.1% ZnO and ZnCO3, respectively. In a quantitative analysis of soluble Zn in liquid medium supplemented with 0.1% ZnO, the isolate KAH109 showed the maximum soluble zinc concentration of 62.89 mg L−1. Among the six isolates, the isolate KAH109 also produced the most indole-3-acetic acid (IAA) at 33.44 mg L−1, whereas the isolate KEX505 also produced IAA at 17.24 mg L−1 along with showing zinc and potassium solubilization activity. These strains were identified as Priestia megaterium KAH109 and Priestia aryabhattai KEX505 based on 16S rDNA sequence analysis. In a greenhouse experiment conducted in Nakhon Pathom, Thailand the ability of P. megaterium KAH109 and P. aryabhattai KEX505 to stimulate the growth and production of green soybeans was examined. The results revealed that inoculation with P. megaterium KAH109 and P. aryabhattai KEX505 considerably increased plant dry weight by 26.96% and 8.79%, respectively, and the number of grains per plant by 48.97% and 35.29% when compared to those of the uninoculated control. According to these results, both strains can be considered as a potential zinc solubilizing bioinoculant to promote the growth and production yield of green soybeans.

“…In 2021, the Office of Agricultural Economics (OAE) reported that the production volumes of cassava, soybean and groundnut in Thailand were approximately 35 million tons, 50 thousand tons and 35 thousand tons, respectively [ 1 ]. In Thailand, calcareous soils are widely used for cultivating economic crops and zinc deficiency frequently appears in the soil [ 2 - 4 ]. Calcareous soils contain high levels of calcium carbonate that affect low-bioavailable zinc concentrations due to some of the zinc adsorbed on calcium carbonate in this soil [ 5 ].…”

Zinc-solubilizing bacteria can convert the insoluble form of zinc into soluble forms available to plants. This study was conducted to isolate and screen zinc-solubilizing actinobacteria from rhizosphere soils and to assess their effect on vegetable soybean growth. In total, 200 actinobacteria strains belonging to 10 genera were isolated from rhizosphere soil samples. Among these isolates, four showed zinc solubilization with solubilizing index values ranging from 3.11 to 3.78 on Bunt and Rovira agar supplemented with 0.1% zinc oxide. For the quantitative assay, in broth culture, strains CME34 and EX51 solubilized maximum available zinc contents of 529.71 and 243.58 μg/ml. Furthermore, indole-3-acetic acid (IAA) and ammonia were produced by these two strains, the strain CME34 produced the highest amount of IAA 4.62 μg/ml and the strain EX51 produced the highest amount of ammonia 361.04 μg/ml. In addition, the phosphate-solubilizing abilities in Pikovskaya’s medium of CME34 and EX51 were 64.67 and 115.67 μg/ml. Based on morphological and biochemical characterization and 16S rDNA sequencing, the strains CME34 and EX51 were closely related to the genus Streptomyces . In a greenhouse experiment, single-strain inoculation of Streptomyces sp. CME34 or EX51 significantly increased the shoot length, root length, plant dry weight, number of pods per plant and number of seeds per plant of vegetable soybean plants compared to the uninoculated control. These findings facilitated the conclusion that the two Streptomyces strains have potential as zinc solubilizers and can be suggested as bioinoculants to promote the growth and yield of soybean.
