This is because inorganic fertilizers production consumes an increasing proportion of the global energy budget and the supply of key raw materials, primarily phosphorus is becoming more limited. Therefore, this study was conducted to evaluate the effect of Arbuscular Mycorrhiza Fungi, AMF (<em>Glomus mossae</em>) and compost on soil properties and early growth response of <em>Parkia biglobosa</em>. The experiment was set up at the screen house of the Department of Bioscience, Forestry Research Institute of Nigeria. The experimental design was a 2 x 5 factorial, laid in a Completely Randomized Design (CRD) with four replicates. The treatments used were compost at five (5) levels: 10t/ha, 20t/ha, 30t/ha, 40t/ha, no amendments; and two (2) levels of AMF inoculation (with and without). Data on plant height, number of leaves, collar diameter and dry matter yields were generated and subjected to analysis of variance, and significant means were separated using Duncan’s Multiple Range Test at 5% level of significance. The result shows that mycorrhizal inoculation significantly increased (<em>p&lt; 0.05</em>) plant height, stem diameter and leave numbers when compared with the non-mycorrhizal plants. There was no variation in number of leaves and height among the inoculated treatments as compared with the un-inoculated treatments which are significantly different from each other at -AMF 0 and –AMF 10 respectively. Interaction of AMF and compost at 40 t ha-<sup>1</sup> had the highest plant height with a value of 35.06 cm. Application of 40 t ha-<sup>1</sup> of compost with inoculation significantly increased (<em>p&lt; 0.05</em>) the root dry matter yields while no significant differences were observed in leaves and stem dry matter yield for both inoculated and un-inoculated. The analysis of the soil before and after the experiments could also be comparable to one another as no variation was observed. From the results obtained, it can be concluded that AMF can successfully be inoculated into compost amended soil to improve the performance of <em>Parkia biglobosa</em>.</p> V. A. Olayiwola F. O.

U.S. Nagar, Uttarakhand India <p>Stress is an inevitable part of human life. Every individual encounters different level of stress and has a tendency to develop unique style to respond and cope with it. Dropping out of school is one such stressful event. Despite universalisation of&nbsp;elementary education in India, there are still a significant number of school dropouts in the country. Hence, the research team of Child Development Unit of All India Coordinated Research Project, Pantnagar conducted a study to study the coping strategies used by school dropouts. It also implemented group interventions for the promotion of effective coping strategies. The study included a sample of 52 school dropout adolescents from four purposively selected villages of Distt. Udham Singh Nagar, Uttarakhand. Standardized scales were used for identifying their coping strategies. School dropouts were seen to usually avoid the stressor to reduce its impact. Rarely did they go for understanding the problem and working for more converting it into a challenge to accept and win over. Post intervention there was significant shift in their coping strategies. It led to significant increase in practice of coping styles like logical analysis, positive appraisal, seek guidance &amp; support, problem solving and significant decline in the use of coping strategies like cognitive avoidance, acceptance, seek alternative rewards, emotional discharge post intervention.</p> Ritu Singh Niharika Bisht Huma Parveen Neera Agrawal ##submission.copyrightStatement## 2019-09-13 2019-09-13 1 8 10.9734/cjast/2019/v37i430294 Energy Potential Study of Some Tropical Wood Species from Nigeria <p><strong>Aims: </strong>To carry out experimental study of the energy potential of some tropical wood species.</p> <p><strong>Study Design:</strong> It involved sample collection, experimental analysis and numerical validation of the obtained calorific values.</p> <p><strong>Place and Duration of Study:</strong> National Centre for Energy Research and Development (NCERD), University of Nigeria, Nsukka, Enugu State, Nigeria between November 2016 and September 2018.</p> <p><strong>Methodology:</strong> Wood waste (saw dust) from ten (10) selected tropical wood species sourced from sawmills in Benin City, Nigeria were subjected to proximate analysis, ultimate analysis as well as energy content study.</p> <p><strong>Results: </strong>Thermal conversion characteristics of low ash content (0.2 – 2.76%), very high volatile matter (87.51 – 90.94%), low moisture content (8.62 – 10.53%.), relatively high carbon, hydogen and oxygen contents as well as low nitrogen and sulphur contents were observed. Obtained calorific values were validated using three already existing correlations.</p> <p><strong>Conclusion:</strong> Among the 10 species studied, <em>Afzelia africana</em> (Apa) was found to be best suited for energy generation while <em>Triplocyton scleroxylon</em> (Obeche) was found to be least suited.</p> J.
