“…While, concentrate 10 ppm was more effective on fresh weight that was related to length and diameter of fruit, as well as the fruit yield kg/plant and ton/hectare. In the same trend found by Zheng et al [39] It was found that the temperature of preparation Mn0.5Zn0.5Fe2O4 NPs had a significant effect on proximate components of the squash leaves during two seasons 2017 and 2018 ( Table 4). showed that the change in the temperature of preparation of Mn0.5Zn0.5Fe2O4 NPs had a role on photosynthesis processes of leave squash; this may be due to the change of the size and the shape of the prepared nanoferrite (Fig.…”

This study aims to synthesize manganese zinc ferrite nanoparticles (Mn0.5Zn0.5Fe2O4 NPs) using a green chemistry synthesis technique and investigate their efficiency as nanofertilizers for squash plant (Cucurbita pepo L). In this work, Mn0.5Zn0.5Fe2O4 NPs were successfully prepared at different temperatures via simple template-free microwave-assisted hydrothermal route and used as foliar nanofertilizers for squash plant. The physicochemical characteristics of the as-prepared ferrites were investigated using X-ray diffraction (XRD), N2 adsorption-desorption isotherm, field emission scanning electron microscopy (FE-SEM) and high resolution transmission electron microscopy (HR-TEM) techniques. The prepared nanoferrites showed type IV adsorption isotherm characteristic for mesoporous materials. FE-SEM and HR-TEM imaging proves the production cubic shaped nanoparticles with average particle size 10-12 nm. Also the impact of using different concentrations of Mn0.5Zn0.5Fe2O4 NPs on vegetative growth, minerals content and the yield of squash plant were investigated. The result showed that the highest vegetative growth for squash appeared with plants supplied by Mn0.5Zn0.5Fe2O4 NPs synthesized at 180°C. On the contrary, the yield of squash recorded the best with 160°C. As for the use of different concentrations of Mn0.5Zn0.5Fe2O4 NPs, it was found that the use of the lowest concentrations gave the highest values of vegetative growth and yield characters. The chemical content of the squash plant differs from the components of proximate value and the elements according to the temperature used in the composition of the compound Mn0.5Zn0.5Fe2O4 NPs and its concentrations. Accordingly, these nanoferrites can be considered as good candidates for Cucurbita pepo L fertilization.

“…IAA and ALA were reported not only to promote plant growth but also to regulate plants spatially and help them adapt to abiotic stress (Blakeslee et al, 2019;Grobelak et al, 2019). Soil acidification affects the bioavailability of plant nutrients, especially inefficient nitrogen sources (Hao et al, 2019). This present study reported that R. palustris KKSSR91 was able to secrete IAA (29.58 mg/L) and ALA (2.89 mg/L) and fix N 2 from its environment (Figure 4; Tables 1 and 2).…”

To screen acid tolerant purple nonsulfur bacteria (PNSB) isolated from peat swamp forests for their abilities to produce plant growth promoting substances (aminolevulinic acid: ALA, siderophores, indole-3-acetic acid: IAA) and also release ammonium from N2 fixation. Among 10 PNSB isolates grown in basic isolation medium (BIM), pH 4.5 found that strain KKSSR91 was the most effective to release ALA and siderophores under microaerobic light conditions; while strain KTPWG11 exhibited highest production of siderophores under aerobic dark conditions. Based on ALA production in medium containing 60 mM glycine, 4 PNSB isolates were selected for further studies and found that strain KTSSR92 produced highest IAA at 36.9 mg/L. All of them were able to release NH4 + , but no activity to solubilize phosphate. In addition, maximal ALA production in the medium supplemented with glycine by strain KKSSR91 was 2.89 mg/L at 4000 lux light intensity. Seed germination index (GI) of kidney bean (Phasecolus vulgaris L.) test using strain KKSSR91 at 1 g fresh biomass/L, pH 4.5 was 68.81% compared with a control in distilled water as only 58.68%. Strain KKSSR91 was identified using 16S rRNA sequencing and found that it showed 99% similarity with Rhodopseudomonas palustris.

“…The analysis of results from PCA arises two issues to analyze: 1) the trend of heavy metal accumulation in seeds when urea is applied as fertilizer and 2) the decrease of Ni content in seeds by same reason. In the first case, there is several reports indicating the influence of urea in soil acidification [16,17], increasing in consequence the availability of heavy metal as was previously explained [14,18]. Nevertheless, the reduction of Ni in seeds can be explained by it inclusion as prosthetic group in urease enzymes of microbial community of soil [19] that in spite soil acidification by urea can make Ni more available, microbiological synthesis of urease in soil -which is activated by urea-could capture Ni reducing his availability for plant and in consequence diminish the Ni content in seed [20].…”

In this work the effects produced by two treatments on maize crop samples have been studied. Analysis of maize grain based on two types of agronomical conditions was performed on: (a) lots treated with different fertilizers and (b) lots with different crop density. Analysis was carried out by microwave induced plasma with optical emission spectrometry (MIP OES) and included the quantification of 11 elements: Ca, Cd, Cr, Cu, Fe, Mg, Mn, Ni, P, Pb and Zn. With the purpose of understand the effect of agricultural practices on elemental profile, principal components analysis (PCA) and cluster analysis (CA) were used as chemometrics tools, finding a correct grouping of each crop based on the type of treatment. The obtained models can be useful to evaluate agricultural strategies, as well as for determining potential yields in maize crops.
