“…The intake of digestible OM and N were highest at higher levels of supplementation for both pseudostem and corm diets, which may have increased the supply of available N and energy. Moreover, DM degradability (Nurfeta et al., 2008b) and non‐fibre carbohydrate content (Nurfeta et al., 2009) of corm was higher than that of pseudostem. The quantity, quality and degradability of the carbohydrate and N components influence the activity of ruminal micro‐organisms and diet utilization (NRC, 1985).…”

The aim of this study was to investigate the effects of different levels of Desmodium intortum (Desmodium) hay supplementation in sheep fed fixed amounts of enset pseudostem or corm and a basal diet of wheat straw on intake, digestibility and nitrogen utilization. Eighteen male sheep with a mean (± SD) live weight of 20.5 ± 1.45 kg were assigned to six treatments in a completely randomized design and fed either 108 g dry matter (DM) enset pseudostem or 165 g DM enset corm each with three levels (100, 200 and 300 g) of hay supplementation. For the pseudostem diets, there was no significant difference in total DM intake. Total crude protein (CP) intake and N retention increased with increasing levels of hay in both pseudostem and corm diets. The apparent digestibility of DM, OM, CP, acid detergent fibre and neutral detergent fibre (NDF) and microbial nitrogen supply (MN) at 100 g was lower that other levels of supplementation. For the corm diets, total DM and OM intake and MN supply increased with increasing levels of hay. The digestibility decreased (p < 0.001) with increasing levels of supplementation. The results suggest that at least 300 g (395 g/kg dietary DM) of Desmodium hay is required in pseudostem diets, whereas 200 g (337 g/kg dietary DM) may be sufficient in corm diets for efficient nutrient utilization.

“…Pseudostem and corm are poor in crude protein (CP) (Fekadu and Ledin, 1997; Nurfeta et al., 2008b). Fekadu and Ledin (1997) fed enset leaf and pseudostem to non‐lactating cows with or without supplementation of urea.…”

“…Considering the importance of enset as a dietary staple food, compared to other regional crops only a relatively small number of nutritional analyses have been undertaken on raw enset plant tissues (Fanta & Satheesh, ; Fekadu & Ledin, ; Mohammed et al, ; Nurfeta, Eik, et al, ), covering a small selection of varieties (max n = 10), with a low number of replications (max n = 3), summarized in Table . Overall, the calorie content of kocho per 100 g of edible material is reported 200 kcal or 57% lower than the corresponding value for 100 g of food grains (Urga, Fite, & Biratu, ).…”

Enset is a staple food for over 20 million people via its starch-rich corm and pseudostem, yet it is virtually unknown outside a narrow zone of cultivation in southern Ethiopia. Due to acculturation and urbanization coupled with climate change, emerging pests and the introduction of new crops, the extensive indigenous knowledge associated with this crop is in danger of being lost, imperilling the future food security and prosperity of millions of Ethiopians. Here, we synthesize the current state of enset ethnobotanical research, identifying key gaps and challenges, and provide a framework for further enset research to safeguard this important, but neglected, tropical crop. SummaryEnset (Ensete ventricosum (Welw.) Cheesman) is the major starch staple of the Ethiopian Highlands, where its unique attributes enhance the food security of approximately 20 million people and have earned it the title "The Tree Against Hunger".Yet enset-based agriculture is virtually unknown outside of its narrow zone of cultivation, despite growing wild across much of East and Southern Africa. Here, we review historical production data to show that the area of land under enset production in Ethiopia has reportedly increased 46% in two decades, whilst yield increased 12fold over the same period, making enset the second most produced crop species in Ethiopia-though we critically evaluate potential issues with these data. Furthermore, we address a major challenge in the development and wider cultivation of enset, by reviewing and synthesizing the complex and fragmented agronomic and ethnobotanic knowledge associated with this species; including farming systems, processing methods, products, medicinal uses and cultural importance. Finally, we provide a framework to improve the quality, consistency and comparability of data collected across culturally diverse enset-based agricultural systems to enhanced sustainable | 213 BORRELL Et aL.

“…For farmers, enset is more than a year-round staple food, as it provides multiple additional daily 50 benefits yet requires little crop management husbandry. The multipurpose benefits are derived 51 from different enset landraces that are particularly suited for feed, fiber, packaging, construction 52 material as well as providing a medicinal role (Brandt et al, 1997;Nurfeta et al, 2008;Yemataw 53 et al, 2017). Due to its long history of cultivation across diverse ethnic groups, enset has 54 significant cultural and socio-economic value in Ethiopia (Shigeta, 1990;Olango et al, 2014, 55 transferred it to the species Xanthomonas vasicola (Studholme et al 2019 in press).…”

Bacterial wilt, caused by Xanthomonas vasicola pv. musacearum (Xvm), formerly X. campestris pv. musacearum, is the most threatening and economically important disease of enset (Ensete ventricosum), the multipurpose food security crop orphan to south and southwestern Ethiopia. Xvm has also had a major impact on banana and plantain production in East Africa following its detection in Uganda in 2001 and subsequent spread. Effective control of this disease currently relies on integrated disease management (IDM) strategies including minimization of field pathogen inoculum and deployment of wilt resistant enset landraces. Identifying landraces with stable and durable Xvm resistance will greatly accelerate breeding of varieties that can be included as a component of IDM. In this study, 20 enset landraces previously reported to exhibit lower susceptibility to Xvm were grown in pots under open field conditions and inoculated with an aggressive Xvm inoculum isolated from a disease hotspot area. Longitudinal and survival analyses were applied to each landrace, based on disease units representing a combination of area-under-disease progress stairs, disease index and apparent infection rate. Considerable variation was observed among the 20 landraces; however, none exhibited full immunity to Xvm infection. Three landraces, viz. Hae’la, Mazia and Lemat (HML), showed lowest susceptibility to Xvm as evidenced by lower disease units and higher survival rates. Landraces Kuro, Gezewet, Bededet, and Alagena showed similar levels of Xvm infection as did HML, but with lower survival rates. By contrast, landrace Arkia showed the highest infection level and lowest survival rate, suggesting a high degree of susceptibility to Xvm. This study identifies new material that can be used in future breeding programmes to develop Xvm-resistant enset varieties.
