The research was conducted at the screen house of the Department of Forestry and Wildlife, Faculty of Agriculture, Nnamdi Azikiwe University, Awka, Anambra state, Nigeria. The study was carried out from January to May 2021 to access the effect of different potting media on germination and early growth of Newbodia laevis. Treatments were laid out in a Complete Randomize Design (CRD) with four replications. The germination parameters measured were days to germination, germination period and germination percentage while the growth variables measured includes plant height, collar diameter and number of leaves. The potting media used were T1 (topsoil and cow dung), T2 (topsoil and goat dung), T3 (topsoil and poultry dropping), T4(topsoil and sawdust), T5 control (topsoil only). Data collected were subjected to R software, using the following packages: plyr, car, gvlma, one-way tests, user friendly science, ggplot. Results obtained indicated that T1 had the highest germination percentage (85%) followed by T2 and T3 with germination percentages of 82% and 80% respectively. T4 had the poorest germination percentage (60%). The results also showed that the treatment had direct effect on the seedling early growth; the highest mean collar girth was observed in T1 with 1.85 cm while the least was observed in T4 with 0.72 m. The highest mean height was observed in T2 with 22.15 cm while the least was observed in T4 with 7.23 cm. Also, the highest mean number of leaves was observed in T2 with 21leaves while the least was observed in T4 with 7 leaves. Based on the findings of these experiments it is recommended that for maximum growth and optimum germination of Newbodia laevis, T1 and T2 should be used, sawdust had poor germination and growth performance and thereby is not recommended for the early growth of Newbodia laevis seedlings.

“…However, significant progress has been made in Allanblackia parviflora by using proximal and longitudinal sections and by stratifying whole seeds at warm temperature to improve imbibition [149]. Scarification to break seed dormancy was achieved in C. schweinfurthii by physically cracking, removing or burning the seedcoat, to facilitate domestication by farmers [357]. Likewise, the germination of G. kola seeds has been improved by mechanical scarification, storage at room temperature and pretreatment with gibberellic acid (GA3) [358].…”

This paper follows the transition from ethnobotany to a deeper scientific understanding of the food and medicinal properties of African agroforestry tree products as inputs into the start of domestication activities. It progresses on to the integration of these indigenous trees as new crops within diversified farming systems for multiple social, economic and environmental benefits. From its advent in the 1990s, the domestication of indigenous food and non-food tree species has become a global programme with a strong African focus. This review of progress in the third decade is restricted to progress in Africa, where multi-disciplinary research on over 59 species has been reported in 759 research papers in 318 science publications by scientists from over 833 research teams in 70 countries around the world (532 in Africa). The review spans 23 research topics presenting the recent research literature for tree species of high priority across the continent, as well as that in each of the four main ecological regions: the humid zone of West and Central Africa; the Sahel and North Africa; the East African highlands and drylands; and the woody savannas of Southern Africa. The main areas of growth have been the nutritional/medicinal value of non-timber forest products; the evaluation of the state of natural resources and their importance to local people; and the characterization of useful traits. However, the testing of putative cultivars; the implementation of participatory principles; the protection of traditional knowledge and intellectual property rights; and the selection of elite trees and ideotypes remain under-researched. To the probable detriment of the upscaling and impact in tropical agriculture, there has been, at the international level, a move away from decentralized, community-based tree domestication towards a laboratory-based, centralized approach. However, the rapid uptake of research by university departments and national agricultural research centres in Africa indicates a recognition of the importance of the indigenous crops for both the livelihoods of rural communities and the revitalization and enhanced outputs from agriculture in Africa, especially in West Africa. Thus, on a continental scale, there has been an uptake of research with policy relevance for the integration of indigenous trees in agroecosystems and their importance for the attainment of the UN Sustainable Development Goals. To progress this in the fourth decade, there will need to be a dedicated Centre in Africa to test and develop cultivars of indigenous crops. Finally, this review underpins a holistic approach to mitigating climate change, as well as other big global issues such as hunger, poverty and loss of wildlife habitat by reaping the benefits, or ‘profits’, from investment in the five forms of Capital, described as ‘land maxing’. However, policy and decision makers are not yet recognizing the potential for holistic and transformational adoption of these new indigenous food crop opportunities for African agriculture. Is ‘political will’ the missing sixth capital for sustainable development?

“…Tropical forest is known to be very rich in species diversity as well as a home for different variety of micro and macro-organisms including wildlife, due to the unique microclimate it creates [1]. Due to rapid forest depletion in the tropics, the supplies of many useful forest products such as Annona muricata are severely threatened with serious consequences on the well-being of the local people who depend on these products.…”

The importance of appropriate growth media for propagation of Annona muricata seedlings cannot be over emphasized. An experiment was conducted to investigate the effects of biochar and organic soil amendments on seedling development of Annona muricata using different potting media. The treatments were Control; Topsoil only (T0), Mineralized goat dung (T1), Mineralized saw dust (T2), Mineralized poultry dropping (T3) and Mineralized biochar (T4). The experiment was laid out in Completely Randomized Design (CRD). Parameters accessed include seedling height (cm), collar diameter (cm) and number of leaves. The data collected were subjected to analysis of variance and significant means were separated using Duncan multiple range test at 0.05 significant level. Result shows that Mineralized biochar had the best performance in seedling height, collar diameter and number of leaves with mean values of 26.703±1.5488, 4867±0.22904 and 4.4451±1.55031 respectively. While the least performance in seedling height, collar diameter and number of leaves was recorded in the control with mean values of 19.986±1.1265, 0.3230±0.17363 and 3.6765±1.14724 respectively. However, there were significant differences in seedling heights and collar diameter among the treatment types at 5% level of probability, but the number of leaves was not significant. Annona muricata seedlings thrives excellently in biochar potting media. Hence, the use of biochar potting media should be adopted as the best growth media for early growth and development of Annona muricata seedlings.
