At seedling stage, interactive effect among salt stress (0 and 4.5 dSm<sup>-1</sup>), potassium sulphate (KS) application @ 10 mmol L<sup>-1 </sup>and soybean (Cvs. NIBGE-301 and NIGBE-158) was recorded for growth and ion relations.&nbsp;</p> <p><strong>Results:</strong> Germination, biomass, bio vigor, mass vigor and sap vigor of the seedlings and ion relations were affected highly significantly (p≤ 0.01).&nbsp; Under interactive effect of KS and salt stress at vegetative stage, Na<sup>+/</sup>K<sup>+</sup> in the plants declined with KS application. Sulphur and phosphorus concentration in the plants changed under the same conditions.</p> <p><strong>Conclusion: </strong>Induced salt stress revealed germination, seed bio vigor, seeding mass vigor, and seedling sap vigor seedling and other vegetative parameters of soybean cultivars. Potassium sulphate application revealed genotypes differential response to ion relations and growth under salt stress. NIBGE-301 was more tolerant to salt stress and more responsive to potassium sulphate application than NIGBE-158.</p> Badar-uz- Zaman, Zaryab Gul, Muhammad Suhaib, Muhammad Ishaq, Haris Khurshid ##submission.copyrightStatement## Sat, 31 Jul 2021 11:17:29 +0000 The Effect of Land Uses on Soil Erodibility (Index) and Soil Loss of the Keana Geological Sediments of Parts of Nasarawa State, Nigeria <p>The effect of land uses on soil erodibility and soil loss of the Keana geological sediments of parts of Nasarawa State, Nigeria was investigated in this study. Geographic positioning system (GPS) was used to identify three land uses (agricultural, forested, and residential). Soil samples were collected from top soils at 0-30 cm depth using core sampler from 1 ha of each land use in 8 settlement communities (16 locations). Standard laboratory methods for soil analysis were followed for determination of Dispersion ratio, Erosion ration, Clay ratio and Modified clay ratio. Linear regression and correlation were used to determine the logical relationship between the erodibility index and corresponding soil loss. The soils from the study area were classified as sandy loam and sandy clay loam with high density, high permeability and porosity making them less vulnerable to shear stress. Dispersion ration (DR) modified clay ratio (MCR), Clay ratio (CR) and Erosion ratio (ER) where high, which suggests that soils from the study area are vulnerable to erosion at various degree of susceptibility.&nbsp; Mean value of erodibility factor (K) and predicted soil loss of 0.0492, 0.0460 and 0.0357; 7.77, 7.20 and 5.48 tonnes/hectare/year&nbsp; for agricultural, forested, and residential&nbsp; lands respectively. The findings suggest that land uses influence the soil erodibility in the formation is in this order residential land &gt; agricultural land &gt; forested land use. The erosion class is ‘very low’ for forested (soils in this class have very slight to no erosion potential), ‘low’ (soil losses will occur) for agricultural and residential land uses respectively. These findings suggest that soil erodibility has been significantly influence by land use change in Keana geological sediment.</p> M. G. Abubakar, M. O. Udochukwu, O. S.

The number of bacteria and fungi present in both treated and untreated soil was then enumerated and the isolates determined.</p> <p><strong>Place and Duration of Study: </strong>The study is a cross sectional research and was conducted on two Farm lands located at Yola capital city of Adamawa state Nigeria wheresoil samples were collected and Microbiology laboratory of Modibbo Adama University Yola were the sample was processed and analyzed. The study was conducted from February to May of 2021.</p> <p><strong>Methodology: </strong>Bacteria and fungi were isolated from soil samples before and after treatment of the soils with N-(phosphonomethl)-glycine(Glyphosate) herbicide at different concentration, the bacteria and fungi populations isolated both before and after the treatment were compared.</p> <p><strong>Results: </strong>The study showed that Glyphosate herbicide caused reduction in the bacterial and fungal count from 3 days of treatment up to 15 days. The bacterial count reduced from 6.1x10<sup>8</sup>cfu/g in the untreated soil to 1.6x10<sup>8</sup>cfu/g on the treatment. Also the fungal count reduced from 1.0x10<sup>8</sup>cfu/g in the untreated soil to 5.0x10<sup>7</sup>cfu/g after 15days of soil treatment. Both the bacterial and fungal count continues to show a gradual decrease up to 15 days in the treated soil. However, several bacteria and fungi were isolated with <em>Bacillus</em> spp. and <em>Micrococcus</em> spp. having the bacteria with highest occurrence with 42(19.91%) and <em>Aspergillus</em>spp. as the fungi with the highest occurrence with 12(42.85%). Statistical analysis of the data obtained indicated that At 95% confidence level, there is a significant difference in the population of bacteria and fungi before and after the soil treatment <em>P-value</em>(T˃t)=.001</p> <p><strong>Conclusion:</strong> The study revealed that Glyphosate herbicide has a negative effect on soil bacteria and fungi population.</p> Halima Isa, Mohammed Bashir, Maryam Ibraheem, Aisha Mahmud Marafa ##submission.copyrightStatement## Fri, 27 Aug 2021 00:00:00 +0000
