N. Ihejiofor U. N. Ukwu uchenna.ukwu@unn.edu.ng G. O. Adeoye <p><strong>Aim:</strong> To investigate growth and yield response of greengram to different levels of Kolgrace organic fertilizer with a view to determining the most favorable application rate for greengram production.</p> <p><strong>Study Design: </strong>Completely randomized design (CRD) with treatments replicated five (5) times.</p> <p><strong>Place and Duration of Study:</strong> Screenhouse of the Department of Agronomy, University of Ibadan, Nigeria, between July to November 2016.</p> <p><strong>Methodology:</strong> Six levels of kolgrace organic fertilizer were used (0.00, 0.50, 1.00, 2.00, 4.00 and 8.00 t ha<sup>-1</sup>). Top soil (0 -15 cm) was collected from the Teaching and Research Farm of the Department of Agronomy, and leached of nutrients by soaking and washing in water for 24 hours. 2 kg of air-dry soil was mixed with the appropriate fertilizer rate and filled in each pot. 3 seeds were sown per pot and thinned to 1 seed at 2 weeks after sowing (WAS). Chemical analysis of air-dry soil sample and Kolgrace fertilizer were done at the soil chemistry laboratory of the Department of Agronomy, University of Ibadan, Nigeria, to ascertain their elemental composition. Soil particle size distribution [1], Soil pH [2], exchangeable K and Na [3], exchangeable Mg and Ca [4], exchangeable acidity [5], organic matter and organic carbon [6], available P [7], Nitrogen [8] and micronutrients (Mn, Fe, Cu and Zn) [4] were determined.</p> <p><strong>Results:</strong> Application rates were significant (p&lt;0.05) for all the traits measured. 0.5 t ha<sup>-1 </sup>was significantly higher in plant height (39.5), number of pods (7.0) and dry pod weight (4.98). Application rate of 1 t ha<sup>-1 </sup>was higher in number of leaves (18.0) although was comparable to application rate of 0.5 t ha<sup>-1</sup>.</p> <p><strong>Conclusion: </strong>Application rate of 0.5 t ha<sup>-1 </sup>was best for three of the five traits measured and is hereby recommended.</p> 2020-07-29T00:00:00+00:00 ##submission.copyrightStatement## https://journalajraf.com/index.php/AJRAF/article/view/30105 Relationship Underlying Seedlings Composition and Abundance of Mature Tree Species at Coral Rag Forest of Mnarani Ruins 2020-08-11T09:21:11+00:00 Mercy Jebiwott Korir mercykorir3317@gmail.com Joyce Mnyazi Jefwa Michael Ajanja Sakha <p>The tropical regions have a rich diversity of tree species which provide the basis for a number of different forms and scales of economic activity. This study therefore was conducted with an aim of enhancing the knowledge of tree species diversity (seedlings and mature trees), and their relationship at the site. The experiment was laid out in three transects and quadrants in the forest: for mature trees the transects measured 100 m by 20 m, whereas for the seedlings quadrants measured 5 m by 5 m. That is along the ocean (T1), along human settlement (T2) and along the forest path (T3). Data was collected by counting mature trees species and seedlings. Data was analysed using R software 3.4.4 and results showed that a total of 22 tree species were recorded in the forest. In T1, the highest (22) species richness was recorded with 4 tree species restricted to the site (<em>Bourellia nemoralis</em>, <em>Flueggia virosa</em>, <em>Turraea wakefieldii </em>and <em>Eryithrinia abyssinica</em>). <em>Combretum schumanii </em>was most abundant in mature trees (89) followed by <em>Lecaniodiscus fraxinifolius (36)</em>, <em>Ochna thomasiana </em>(21) and <em>Adansonia digitata </em>(14). All the above abundant species except <em>Adanosnia digitata </em>(2) were also abundant in seedlings with (189), (11) and (21) seedlings respectively. In T2, 9 tree species were recorded. <em>Azadirachta indica </em>was the most dominant in both mature trees (40) and seedlings (261) while <em>Sterculia appendiculata recorded the lowest </em>(1) and (0) respectively<em>. </em>T3 was rich with three exotic tree species namely <em>Delonyx regia</em>, <em>Azadirachta digitata </em>and <em>Lannea schweinfurthii</em>. <em>Lecaniodiscus fraxinifolius </em>was the most common with (35) followed by <em>Combretum schumanii </em>(11). While the seedlings were (23) and (67) respectively.&nbsp; In conclusion, it was evident that anthropogenic factors reduced species richness and the corag rag forest had more indeginous tree species and good seed recruitment.</p> 2020-08-11T00:00:00+00:00 ##submission.copyrightStatement## https://journalajraf.com/index.php/AJRAF/article/view/30106 Assessment of Threats to Survival of Biodiversity and Ecosystem Services in Stubbs Creek Forest Reserve, Akwa Ibom State 2020-08-13T09:03:32+00:00 Nsikak E. Umoren nsyumoren@yahoo.com Gordian C. Obute Kingsley O. E. Ukaegbu <p>Different climes are endowed with a myriad of biodiversity resources, ecosystem services and functions suited to sustenance of lives and providing assorted raw materials for sustainable development if effectively managed. There is global outcry about disappearing biodiversity and mismanaged fragile ecosystems. Human endeavours are strongly implicated in the resulting distorted ecological balance. This study therefore sets out to examine the cause and effects of the declining singular gazetted forest reserve in Akwa Ibom State, the Stubbs Creek Forest Reserve (SCFR). Threats to survival of biodiversity and ecosystem services (BES) were studied qualitatively (a combination of field observation and engagement with key stakeholders of SCFR). Community forest occupational user-groups, corporate players and the public sector were engaged. Outcomes of the study suggest that among other factors, institutional weakness and unsustainable consumption patterns may be of primary concern in tackling further degradation. A quick concerted intervention is required to reposition SCFR for alignment with global sustainable development goal 15, ecosystem restoration and climate change adaptation.</p> 2020-08-13T00:00:00+00:00 ##submission.copyrightStatement##
