<p>Phosphate solubilize bacteria plays a key role on an increasing bioavailability of the insoluble phosphates through the action of releasing organic acids. The research was conducted on soil microbiology laboratory to evaluate the selected physiological and biochemical characteristics of the isolated strains. Series of research methodology was used to evaluate eco-physiological, morphological and biochemical tests. The nominated isolates show gram negative, mucous texture and all of them grown well at pH 6 and 7, 15-35℃ temperature and 1-1.5% salt concentration (Na Cl2). Promising result was observed from 1.5mg/l and 3.0mg/l of MnSO4 and 0.25mg/l ZnSO4. Regarding to carbohydrate utilization, all of the tested isolates were utilized the tested carbon source. Promising result was obtained from phosphate solubilization, the highest solubilization index was recorded from IS-B (2.21) followed by IS-E (2.18). The pull-down of pH from 7.0 to 4.75 shows that the ability of the isolated strain to release phosphates. Therefore, the authors concluded that, effective phosphate solubilize bacteria recommended for acidic soils particularly for the study sites to enhance phosphorus uptake to plant growth.</p>

<p>The performance of the genotypes depends on the genetic potential of the crop and the environment in which the crop is grown. The present study was aimed to identify and release of stable high yielding and medium maturing soybean variety with better agronomic performance in western Ethiopia. To this end, seventeen soybean genotypes including the standard check, Korme, were evaluated at three locations (Bako, Gute and Boshe) for two consecutive main cropping seasons (2017-2018). Additive main effect and multiplicative interaction (AMMI), Genotype and Genotype by environment (GGE) interaction biplot and regression analysis were computed using R- statistical software to identify stable genotype across locations in both years. The environment, genotype and genotype x environment interaction (GEI) effects were highly significant (p&lt;0.001) based on combined analysis of variance and additive main and multiplication interaction (AMMI) model. The three models revealed similar result in that PM-12-20, PM-12-32, PM-12-18 and PM-12-39 were stable and widely adapted genotypes. However, the genotypes PM-12-31, PM-12-45 and PM-12-43 had higher regression coefficient (b_i) value showing that these genotypes were sensitive to changes in environmental conditions and tend to give high yield at a favorable environment. Genotype PM-12-37, now named as Billo-19, was relatively stable and high yielding thus released for the western Ethiopian and other areas with similar agro-ecologies.</p>
