“…Sf 1 ). Nevertheless, as the effect of nutrients on a plant's response to disease is often species specific (Ghorbani et al, 2009;Spann et al, 2009), the role of micronutrients in enset is an important avenue for future research. Second, interferences in the uptake between K, Mg and Ca have been evidenced to influence plant health in banana crops (e.g.…”

“…Enset typically grows in gardens on weathered tropical soils, and animal manure and compost from household refuse are used as soil amendments (Elias et al, 1998;Tamire and Argaw, 2015;Tsgaye and Struik, 2002). However, the supply of these organic inputs is limited and mainly acquired from free-range cattle, which puts an additional strain of overgrazing on the already degraded communal lands (Amede and Taboge, 2007;Assefa and Bork, 2017;Elias et al, 1998;Garedew and Ayiza, 2018). Hence, the optimal use of scarce nutrient resources is vital, yet there are no generally accepted recommendations to the enset farmers in the region.…”

“…Enset Xanthomonas wilt (EXW), a bacterial wilting disease caused by Xanthomonas campestris pv. musacearum (Xcm) causes significant damage to enset gardens (Garedew and Ayiza, 2018;Yemataw et al, 2017;Yirgou and Bradbury, 1968). It can cause yield losses up to 100% (Yemataw et al, 2016), and all cultivated varieties are susceptible (Merga et al, 2019), albeit some variation in tolerance occurs (Handoro and Michael, 2007;Welde-Michael et al, 2008a;Wolde et al, 2016).…”

Abstract. Enset (Ensete ventricosum) is a productive, drought-tolerant and multipurpose food security crop grown in the densely populated Ethiopian highlands. It is a so-called orphan crop, and its production suffers from a lack of information on proper soil fertility management and its interaction with bacterial wilt disease caused by the pathogen Xanthomonas campestris pv. musacearum. The aim of this study was therefore to assess soil–plant nutrient variation within enset home gardens at three altitudes (ranging from 2000 to 3000 m above sea level – a.s.l.) in the Gamo highlands and investigate whether this variation affects disease prevalence. Altitude in the rift valley covaries with soil leaching, and plant available P, Ca and Mg in soils significantly raised with decreasing altitude. Soil carbon and most nutrients reached very high levels in the gardens, whereas the more distant outfields were severely nutrient deprived. Differences in management intensity within the garden caused soil pH, conductivity, total organic carbon, total N and available P, K, Ca, Mg, Mn and Fe levels to significantly decline with distance from the house; yet, this decrease in soil nutrients was not mirrored in a response of foliar nutrient content, except for N. Hence, over-fertilization is likely, and establishing evidence-based nutrient recommendations for enset would benefit soil quality and productivity both in the gardens and in the outfields. Disease prevalence was high in the study area, with one-third of the farms affected in the recent past. Although more experimental work is needed to exclude confounding factors, our data indicate that the effects of altitude, P fertilization, micronutrients and K-Ca-Mg balance are promising avenues for further investigation into Xanthomonas wilt disease susceptibility.

“…Secondly, the enset Xanthomonas or bacterial wilt (EXW) caused by Xanthomonas campestris pv. musacearum (Xcm) is wreaking havoc in enset dependent farming communities since its first outbreak in Ethiopia (Garedew and Ayiza, 2018;Yemataw et al, 2017;Yirgou and Bradbury, 1968).

Abstract. Enset (Ensete ventricosum) is a productive, drought-tolerant and multipurpose food security crop grown in the densely populated Ethiopian highlands. Its production suffers from poor soil fertility management and a bacterial wilt disease caused by the pathogen Xanthomonas campestris pv. musacearum. The aim of this study was to assess soil-plant-nutrient variation within enset home gardens over three different altitudes (ranging from 2000–3000 masl) in the Chencha catchment of the Gamo highlands and investigate whether this variation affects disease prevalence. Plant available P, Ca and Mg significantly increase with decreasing elevation but significantly decline with distance from the house. In addition, soil pH, conductivity, total organic carbon (TOC), total N, available K, Mn and Fe levels significantly decline with distance from the house. This indicates that soil fertility factors are influenced by both agro-ecology and farmers' management practices. Moreover, most nutrients reach very high levels in the garden whereas the more distant outfields are severely nutrient deprived. Plant nutrient levels are not correlated to soil nutrient levels except for N. Twenty two percent of the studied farms are symptomatic for bacterial wilt and its prevalence increases with decreasing elevation. Symptomatic gardens have a higher soil pH and available P, K and Ca levels. We conclude that soil fertility management in enset gardens should be optimized in relation to agro-ecological conditions and that both elevation and soil nutrient status need to be considered when developing strategies to curb the current Xanthomonas wilt epidemic.
