“…Medium for growing plants is an important component as this will provide nutrient for plants to grow (Mukhtar, 2019). Even though media types in this study were not significant (p<0.05), the growth patterns can still be seen (Figure 3).…”

Screw tree (Helicteres isora) is a shrub species (Fam: Malvaceae) with 1.5–4 m in height and with multi-main trunks up to 9–12. In Indonesia, kayu ules has been used as a traditional medicine, known as jamu, and has been commercialized. In order to cultivate this species, vegetative propagation is likely promising compared to the generative propagation since seed viability is low and cannot be stored for longterm. Nevertheless, there is a lack of information on which diameter classes, media types and light intensities would give the best result for vegetative propagation. This research aimed to obtain information on which diameter classes and media that were suitable for kayu ules stem cutting propagation and to what degree the light intensity would be best for the growth of the seedlings of kayu ules. Three diameter classes and four media types were employed in a complete random design under the greenhouse environment. Three months old good quality vegetatively-propagated seedlings were transplanted under two light intensities (under transparent canopy and shading net). The result showed that considering the factor of diameter classes and media in kayu ules stem cutting propagation, it had improved the survival of the stem cutting. Diameter class I was best grown in media type 3 with 46.67 ± 12.2 % of survival rate, diameter class II was best grown in media type 2 with 38.67 ± 11.6 % of survival rate, whereas diameter class III was best grown in media type 4 with 52 ± 6.9 % of survival rate. The transplanted seedlings also grew significantly better under transparent canopy with higher light intensity. The distinctive features of screw tree under shading net were wider leaf area, higher specific leaf area and relative water content but it was lower in above ground dry biomass compared to the kayu ules under transparent canopy.

“…They are used in several kinds of agricultural research to calculate crop parameters 20 . In some studies, the suitable performance of vegetation indices to determine plant nutrition has not been proven, the main reason being the weak performance of these indices in vegetation structure 21 . Combined indices could be used in places where producers make a special effort to find water resources to irrigate their fields and crops.…”

BACKGROUND: Spectral reflectance measurements and vegetation indices have been used widely to monitor plant nutritional status. Remote sensing methods are very fast, convenient, and non-destructive techniques for estimating crop nutrition indices. With the rapid development of remote sensing satellites, unmanned aerial vehicles, and the Internet of Things, remote sensing will increasingly be used in crop nutrition diagnosis. This can lead to lower operating costs for fertilization and can minimize loss of productivity. RESULTS: In this study, satellite images were used for 2 years to evaluate the use of vegetation indices for crop nutrition mapping, in two regions, located in the cities of Ray and Karaj. For each farm, eight reference points in each year were selected to determine the crop nutrition status for model development and accuracy assessment. Then, ten spectral vegetation indices were used to calculate the crop nutrition content at mid-season and at the end of the season. The results indicated that transformed chlorophyll absorption in reflectance index (TCARI) and modified chlorophyll absorption in reflectance index (MCARI) had the highest R 2 and the lowest RMSE values, respectively (R 2 TCARI = 0.83, RMSE TCARI = 12.47 kg ha −1 and R 2 MCARI = 0.75 and RMSE MCARI = 14.47 kg ha −1). CONCLUSION: The performance of TCARI and MCARI was strong across the two farms and allowed the creation of highly accurate crop nutrition maps. In conclusion, the use of the near infra-red and red-edge bands in mid-season led to better results than vegetation indices calculated at the end of the season or that do not included the red-edge band.

“…Vegetative propagation is used to capture elite phenotypes as putative cultivars and has been evaluated in a number of important tree species in the region, including Prosopis africana [433], Argania spinosa [435,436], B. aegyptiaca [437,438], A. digitata [76] and V. paradoxa [136]. For instance, in Niger, Prosopis africana has been found to be amenable to air layering with no significant differences between the diameter classes and between the positions, although the success rate was low (28% after 4 months) [439].…”

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?
