“…Hence, Pseudomonas aeruginosa B18 has an important role in plant growth and biological control mechanisms in sugarcane (Singh et al, 2021a). Furthermore, many studies have reported that biocontrol agents, such as Bacillus, Pseudomonas fluorescens, and Trichoderma spp., can inhibit the growth of Sporisorium scitamineum (Tegene et al, 2021;Wang et al, 2021;Rees et al, 2022;Vijitrpanth et al, 2023). Most bacteria, including the denitrification-active actinomycete Marmoricola, Iamia, and Reyranella, are helpful to smut resistance (Duan et al, 2023).…”

Environmental stresses are the main constraints on agricultural productivity and food security worldwide. This issue is worsened by abrupt and severe changes in global climate. The formation of sugarcane yield and the accumulation of sucrose are significantly influenced by biotic and abiotic stresses. Understanding the biochemical, physiological, and environmental phenomena associated with these stresses is essential to increase crop production. This review explores the effect of environmental factors on sucrose content and sugarcane yield and highlights the negative effects of insufficient water supply, temperature fluctuations, insect pests, and diseases. This article also explains the mechanism of reactive oxygen species (ROS), the role of different metabolites under environmental stresses, and highlights the function of environmental stress-related resistance genes in sugarcane. This review further discusses sugarcane crop improvement approaches, with a focus on endophytic mechanism and consortium endophyte application in sugarcane plants. Endophytes are vital in plant defense; they produce bioactive molecules that act as biocontrol agents to enhance plant immune systems and modify environmental responses through interaction with plants. This review provides an overview of internal mechanisms to enhance sugarcane plant growth and environmental resistance and offers new ideas for improving sugarcane plant fitness and crop productivity.

“…Sugar industries also use to schedule management practices based on weather forecast which may favor or disfavor the disease. Of course, Tegene et al (2021) demonstrated a significant association between smut intensity and varieties, crop cycle, soil type, growth stage, irrigation system, fertilizer utilization and weed intensity. However, the study failed to consider the association between smut intensity and meteorological variables.…”

“…Moreover, Zekarias et al (2010) reported a variable smut incidence of 3.78%, 3.61%, and 1.05% at Wonji, Metehara and Fincha, respectively. Furthermore, Tegene et al (2021) have also identified smut as the most important constraint in sugarcane production and recorded smut intensity reaching up to 27% in some of the newly established sugar estates in Ethiopia.…”

The development of sustainable smut management techniques requires an understanding of the impacts of smut on sugarcane growth and the relationships between smut intensity and meteorological variables, varieties, and crop types. Thus, assessments were made with the objectives to 1) determine the effect of smut on the above-ground growth of sugarcane, and 2) quantify the association of smut with weather variables, varieties and crop types. The effect of smut on above-ground growth was assessed in six fields planted with NCo 334 (wider coverage) having 6 months of age in Fincha and Metehara fields in 2021. Data on above-ground growth were taken from 20 randomly selected smut-affected and healthy stools from each field. Besides, 6 years’ data (2015 to 2021) on the numbers of smut-affected stools and smut whips of 79 fields were collected. Furthermore, 10 years’ (2011 to 2021) weather data were acquired from the sugar plantations. The results demonstrated reduction in the above-ground growth of sugarcane in the range of 18.39% and 73.42% due to smut. In addition, weather variables explained about 68.48% and 66.58% of the variability in the number of smut-affected stools and whips respectively. Smut intensity increased with crop types for susceptible varieties. The tight association between the smut epidemic and crop types, varieties, and weather, implied that these parameters must be carefully considered in management decisions. Continuous monitoring of smut disease, meteorological variables, varieties, and crop types in all the sugarcane plantations could be done as a part of integrated smut management in the future.

“…As a result, traditional rainfall patterns are changing; leading to more frequent droughts (USAID 2012).Projections of mean annual rainfall averaged over the country from different models in the ensemble project a wide range of changes in precipitation for Ethiopia, but tend toward increases. By 2030, the RCP4.5 10th percentile (−23%), median (0.6%), and 90th percentile (28%) ensembles for mean annual precipitation indicate high uncertainty in the direction and amount of change across the models (Tegene et al 2021). These empirical evidences indicate that climate change in Ethiopia is already happening, and the impacts are manifest in various places of the country (Zegeye 2018.According to Field et al (2012 and Leroy et al (2016), all four dimensions of food security are potentially affected by climate change through their effects on agricultural production and the incomes of rural households, food prices and markets and on many other parts of the food system (e.g., storage, food quality, and food safety).…”

Ethiopia's diverse agroecological zones showcase a variety of Climate Smart Agricultural (CSA) Practices, yet the documentation and prioritization of best-bet practices have been lacking. To address this gap, this study utilized the Climate Change, Agriculture, and Food Security (CCAFS)-CSA Prioritization framework. This approach was deployed across nine key agro-ecologies in Ethiopia to identify and prioritize CSA practices based on the three pillars of CSA and gender-equity considerations. By employing this participatory framework, this study successfully identified and prioritized over 200 Climate Smart Agricultural (CSA) practices within Ethiopia's nine major agroecological zones. These practices were segmented into four main systems: crop management (40 practices), livestock management (41 practices), soil fertility management (40 practices), erosion control and water management (41 practices), and forest and agroforestry (40 practices). Notably, the results highlighted the significance of CSA practices linked to agroforestry/forestry management, rangeland/forage enhancement, exclosure strategies, and water management in addressing the goals associated with the three pillars (productivity, adaptation, mitigation) of CSA practices simultaneously. The findings also revealed that the majority of Climate Smart Agricultural (CSA) practices focused on improving productivity and enhancing adaptation to climate change. Additionally, the results demonstrated that trade-offs exist among the three pillars of CSA, emphasizing the need for integration with other practices to enhance complementarity and achieve all pillars simultaneously. Overall, this study underscores the importance of combining CSA practices of various categories to maximize their effectiveness and impact in sustainable agriculture
