“…Maximum nodule number (70) was also found in 20 cm × 15 cm size polybag. This is because T4 treatment contains much growing media which supplies more nutrients to the seedlings and the results support the findings of Hossain et al (2009).…”

“…ex Benth.) is an evergreen, exotic, heavily branched, forked bole species, mostly planted on roadsides and railway embankments, parks and gardens because of its ornamental and shade bearer values in Bangladesh (Das and Alam 2001;Hossain et al 2009;Girijashankar 2011;Islam et al 2013). It is a multipurpose tree species and considered as one of the most promising plantation species because of its ability to survive on a wide range of degraded environmental conditions (Alam et al 1991;Das and Alam 2001;Jahan et al 2008).…”

Abstract. Islam MDA, Rahman MDA, Hossain MK. 2019. Effect of container and potting media on raising quality seedlings of Acacia auriculiformis in the nursery. Asian J Agric 3: 26-32. The study elucidates the effect of container and potting media on raising quality seedlings of Acacia auriculiformis in the nursery of the Institute of Forestry and Environmental Sciences, University of Chittagong to find out a suitable container and potting media for raising large scale quality seedlings. The seedlings were evaluated by five container and seven potting media treatments for eight months. A Completely Randomized Block Design (CRBD) was adopted for the study with three replications for each treatment. The Analysis of variance (ANOVA) and Duncan’s Multiple Range Test (DMRT) was tested for the analysis to explore the possible treatment variations. However, the study reveals nodulation with growth parameters; shoot and root dry biomass production and quality index were highest in 20 cm × 15 cm size polybags whereas the highest root length and shoot-root ratio was observed in 15 cm × 10 cm and 15 cm × 13 cm size polybag respectively. Considering the potting media, highest nodulation, growth parameters, shoot dry and fresh weight, shoot- root ratio and biomass were found in combination of soil + cow dung + phosphorus (0.16 g/polybag). Highest root length, root fresh and dry weight, and quality index were found in the combination of soil + cow dung (3:1). Therefore, it is recommended that containers of 20 cm × 15 cm size polybag and with a potting media of soil + cow dung + phosphorus (3 parts soil, 1 parts cow dung + 0.16 g/polybag) combination produce quality A. auriculiformis seedlings in the nursery.

“…At the fifth leaflet, only flattened leaf stalks which were leaves that resembled human ears, thick and greenish in color were produced. These features make this plant adaptable to hot climates and drought [7]. Analysis of variance (ANOVA) indicated significant differences (P<0.05) among soil types and seed pretreatment methods of the Acacia auriculiformis from the different treatment combinations.…”

“…Some degrees or levels of dormancy are naturally associated with its viable seeds which should be pretreated prior to sowing [3,4,5,6]. It is an evergreen tree that is very useful for erosion control and water conservation [7]. It can fix nitrogen after nodulating with a range of rhizobium and brady-rhizobium strains [8].…”

The multiple products derivable from Acacia auriculiformis in terms of its soil nutrient augmentation by virtue of its nitrogen fixation capabilities are incontrovertible. This is in addition to being an ornamental, evergreen and shade providing tree, But its seed dormancy and dearth of knowledge regarding its growth rates in different soil types had hampered large scale production of its seedlings. Thus, an evaluation of the effects of some seed pre-sowing treatments on its seedling emergence (rates and percentages) and morphological growth parameters (external) in different soil types were investigated at the Screen House of the Department of Plant Science and Biotechnology, Adekunle Ajasin University, Akungba Akoko, Ondo State, Nigeria for a period of 8 weeks. The experimental design was a 4 × 3 factorial experiment in completely randomized design comprising 4 different soil types, 3 pre -sowing treatment methods (replicated thrice). Seedling emergence (rates and percentages) and external morphological growth indices (plant height, collar girth, number of leaves and leaf area) were investigated. Analysis of variance (ANOVA) test was Ojo et al.; IJPSS, 30(5): 1-9, 2019; Article no.IJPSS.51910 2 employed in processing the data collected by employing relevant statistical package (SPSS 20.0). Results indicated that seeds pretreated with concentrated sulphuric acid and sowed in sandy loam (a 3 b 1 ) emerged as the best treatment combination in terms of seedling emergence rate and percentage, morphological growth indices (significant at P<0.05) while the control (aobo: river sand with untreated seeds) had the lowest values.

Although deviations from standard guidance for land application of biosolids occur in practice, their importance is largely unknown. A list of such deviations (plausible failure scenarios) were identified at a workshop of industry, regulators, and academic professionals. Next, a survey of similar professionals was conducted to rank the plausible failure scenarios according to their severity, frequency, incentive to ignore control measures, gaps in existing control processes, public concern, and overall concern. Survey participants rated intentional dumping (unpermitted disposal) as the most severe of the failure scenarios, lack of worker protection as the most frequent scenario, and application of Class A biosolids that have failed to meet treatment standards as the scenario for which incentives to ignore control measures are highest. Failure of public access restrictions to application sites was the scenario for which existing controls were judged the weakest; application of biosolids too close to wells was ranked highest for public concern and for overall concern. Two scenarios for which existing controls were considered weaker, site restriction violations and animal contact leading to human exposure, were also rated as frequently occurring. Both scenarios are related in that they (1) involve inappropriate access to a site before the required time has elapsed, and (2) could be addressed through similar biosolids management measures.
