in order to study the effects of simultaneous application of znso4 and biological fertilizer, azotobacter chroococcum and azospirillum brasilense, on grain yield and nitrogen uptake efficiency in rapeseed (brassica napus l.), cv. hyola308, a field experiment was conducted as split plot factorial based on randomized complete block design at research field of faculty of agricultural sciences, uni...

This study was carried out on olive trees cv. Amygdalifolia, to investigate the effect of spraying potassium nitrate, KnO3, and zinc sulfate, ZnSo4, on the fruit weight, dimension and volume. The plants were sprayed with 0, 0.5, 1.0 and 1.5% KnO3 and 0, 0.25, 0.50 and 0.75% ZnSO4 and their combinations in August about halfway through the fruit growth period. The highest fruit weight was observe...

to study the effects of simultaneous application of urea, znso4 and inoculants, (azotobacter and azospirillum), on uptake and nitrogen use efficiency in rapeseed, var. hyola308, a field experiment with split plot factorial layout based on a randomized complete block design was conducted at the research field of faculty of agricultural science, university of guilan in 2008. experimental treatmen...

Zinc sulfate is an inorganic compound: the sulfate salt of zinc and a good source of zinc ions. The molecular 40 formula for zinc sulfate is ZnSO4. A graphic representation of the structure of zinc sulfate is shown in figure 1 41 (Pubchem, 2014). Zinc sulfate appears geologically as a white crumbly salt efflorescence known as “goslarite.” 42 Goslarite, the heptahydrate of zinc sulfate was first...

Pelargonium odoratissimum is a perennial evergreen used as a fragrant ornamental plant. Leaves, green branches and fresh flowers contain essential oils, that have been shown to possess antibacterial, antifungal, antiviral, insecticidal and antioxidant properties. In order to study the effect of foliar spray of ZnSO4 (0, 1000, 2000, 3000 and 4000 mg L-1) on vegetative growth and some physiologic...

Pseudomonas aeruginosa (GRC1) isolated from potato rhizosphere, grew better on succinate medium than tryptic soy medium and produced hydroxamate type of siderophore in iron-deficient succinate medium. When the strain GRC1 was grown in the presence of different metal ion compounds, viz. ZnSO4, MnSO4, MnCl2 and FeCl3 at 6 and 12 microM concentrations individually, ZnSO4 (12 microM) promoted sider...

Zinc oxide nanoparticles (ZnO NPs) are being utilized in an increasing number of fields and commercial applications. While their general toxicity and associated oxidative stress have been extensively studied, the toxicological pathways that they induce in developmental stages are still largely unknown. In this study, the developmental toxicity of ZnO NPs to embryonic/larval zebrafish was invest...

In a 36-d experiment, 32 pigs were depleted of Zn (24 d) using a soy-isolate (basal) diet (17 mg/kg of Zn) and then fed the basal diet (12 d) supplemented with 45 mg/kg of Zn from ZnSO4 (purified zinc sulfate dry powder, ZnSO4.nH2O) or from a Zn amino acid chelate (ZnAAC) to study the effectiveness of these dietary Zn sources in restoring serum and soft tissue Zn concentrations. Concurrently, n...
