Potassium solubilizing bacteria (PSB) are able to dissolve K from K-minerals and enhance plant growth and yield. A field experiment was carried out during 2017/2018-2018/2019 growing seasons in a ...randomized complete block design (RCBD) with three replicates. This study aims to assess the performance of bio-fertilization (Bacillus cereus) as PSB on the growth of potato (Kara Spp) and availability of N, P, and K. Potato plants were fertilized with K-feldspar and inoculated with PSB. The results showed that the PSB significantly increased the plant height (PH), branches number (BN), and shoot dry weight by about 15%, 27%, and 26%, respectively, compared to the untreated one. Soil available K increased by 42% as a result of PSB inoculation, moreover, K uptake by potato tubers increased by 62% in compassion with untreated plants. Leaf N, P, and K concentrations as well as the uptake were significantly increased in the plants inoculated with PSB compared to the un-inoculated plants. The graded weights of potato were increased by 20%, 26%, and 25%, for large, medium, and small size of tubers, respectively as a result of applying of bio-fertilizer. The bio-fertilization of potato with Bacillus cereus significantly increased the total yield of potato by 21% above the untreated plants. The application of K-feldspar (12% total K

Enrichment of soils with organic amendments could increase the content of available nutrients, improve soil chemical characteristics and increase plant growth. In the current pots experiment, the ...influences of biochar (BC), humic acid (HA), and compost (CO) on barely growth were investigated under saline conditions. Barely plants grown on a clay loam soil and irrigated with saline water concentration of (EC = 13.8 dS m

) were amended with BC, HA and CO at a rate of 1 or 3% of soil weight. The results showed that BC, HA and CO treatments had significant effects on the soil salinity, pH, organic matter (SOM), and plant nutrients. The results showed that the high rate application of BC, HA and CO increased the SOM by 14, 75 and 58% respectively, above the control. Consequently, the total chlorophyll as affected by the treatments can be arranged in descending order: BC

> CO
1
> CO

> HA

> C. The high rates of BC, HA and CO increased the dry biomass by 28.0, 21.6 and 39.7% respectively, above the control %, respectively, above the control. The investigated organic amendments increased the nutrients availability and uptake and enhanced the synthesis of chlorophyll in the plant tissues and this may be the reason of increasing the ability of barley to tolerate salinity.
Purpose. To compare clinical outcome of IVCD combined with oral therapy with IVCD alone in patients with toxoplasmic retinochoroiditis. Patients and Methods. Thirty eyes were reviewed. Two equal ...groups were identified (15 eyes each). Clinical outcome measures were resolution of active inflammation, changes in BCVA and CMT, adverse drug reactions, and rate of recurrence. Results. Mean baseline of BCVA 1.08 ± 0.17 and 1.03 ± 0.15 improved to 0.64 ± 0.18 and 0.69 ± 0.17 at the end of follow-up in group I and II, respectively. No statistically significant difference was observed. CMT was 392.6 ± 33.16 μm and 397.3 ± 14.6 μm significantly decreased to 314.7 ± 4.43 μm and 319.6 ± 7.8 μm. Resolution of acute inflammation was achieved in all cases in both groups. There were no recurrent cases in group I, and only one out of 15 (6.7%) in group II. No ocular or systemic adverse events were recorded. Conclusion. IVCD is an effective route of treatment for active toxoplasmic retinochoroiditis that can be used solely without the need to use systemic medications..
