“…Poor seed quality (Hirpa et al, 2010(Hirpa et al, , 2016, potato diseases such as bacterial wilt, late blight, and viruses (Gildemacher et al, 2009;Nasir, 2016), and inadequate soil fertility management (Emana and Nigussie, 2011;Schulte-Geldermann, 2013) are claimed as the main bottleneck to increase potato productivity in the country. However, different strategies have been applied to increase potato productivity in Ethiopia, including seed quality management (seed systems management and seed production) (Gildemacher et al, 2009;Hirpa et al, 2016), water efficient and scheduled irrigation systems (Gebremariam et al, 2018;Alemayehu et al, 2023;Wabela et al, 2023), soil fertility management using nitrogen and phosphorus fertilizers (Sebnie et al, 2021;Woldeselassie et al, 2021;Amare et al, 2022), weed management (Kebede et al, 2016), integrated nutrient management (organic and inorganic mineral) (Girma et al, 2017;Mohammed and Dawa, 2018;Asaye et al, 2022), integrated disease and pest management (prevent bacterial wilt and late blight fungal disease, control of vectors and their viruses) (Wassihun et al, 2019;Andaregie and Astatkie, 2020;Wubet et al, 2022), post-harvest management (Tadesse et al, 2018;Degebasa, 2020), improved marketing systems, knowledge, and information systems, and using agricultural technologies (Gildemacher et al, 2009) are also critical for increasing potato productivity.…”

Environmental data are rapidly accruing on the unsustainability of diets based on animal products, such as dairy and meats. Shifting to alternative sources of protein is inevitable given an increase in the projected global population and protein demand. Left unchecked, a collision between food security and sustainability is imminent. Potatoes could be the strategic food and cash crop to harmonize food security and sustainability worldwide. Recently, there has been a growing interest in extracting proteins from the byproduct of the potato starch industry known as potato fruit juice. These proteins are garnering attention due to their nutritional value, characterized by a well-balanced amino acid profile, as well as their functional properties including emulsifying, foaming, and gelling capabilities. Moreover, these proteins are considered to be less allergenic than some other protein sources. Extracting potato protein, which is sourced as a byproduct, reduces food loss and waste, thereby eliminating pathogenic microorganisms from the environment and mitigating greenhouse gas emissions. Ethiopia is a major potato producer in East Africa. Potatoes help the country increase household income, ensure food security and revenue generation, and produce starch. However, Ethiopia’s potato starch industry has not yet begun protein extraction, despite the vital role of the proteins and the country’s huge cultivation potential. Furthermore, the global potato protein market is experiencing significant growth. This information urgently calls for innovative approaches to assess the impact of extracting protein from potatoes produced in Ethiopia. Therefore, this perspective article has two main objectives. First, to scan the extent of potato production in Ethiopia in relation to environmental sustainability and the economy. Second, to provide prospects on the impact of extracting protein isolate from potatoes produced in Ethiopia on environmental sustainability, Ethiopia’s economy, and human health.

“…Water productivity at the plant scale is the amount of revenue from each drop of water consumed (Molden et al, 2003). At the farm scale, water productivity is the total weight of the crop produced by a unit volume of water (Alemayehu et al, 2023;Mon, 2011;Wang et al, 2023). Water deficit stress in a plant species can cause changes in the structure or metabolic processes such that these changes may occur within seconds after the stress occurs or gradually during a growing season (Pinheiro et al, 2004).…”

Drought is a serious threat to crop growth, and finding new irrigation methods can save water. This study was conducted to investigate water use efficiency and seed yield in mung bean under wick irrigation. Irrigation treatments consisted of the wick irrigation method, surface irrigation (common irrigation) with water equivalent to wick irrigation, and surface irrigation with the double water use of wick irrigation. The results showed that the wick irrigation had a seed weight per plant, 100‐seed weight, seed number per pod, pod number per plant, seed yield, biological yield, water use efficiency of seed, water use efficiency of biomass and net income increase of 164, 14, 28, 80, 164, 128, 164, 128 and 300%, respectively, compared to surface irrigation with an equivalent water volume of wick irrigation. Wick irrigation resulted in increases in plant height, internode length, leaf number per plant, node number per plant, branch number per plant, leaf length and leaf width of 60, 59, 65, 91, 91, 52 and 52%, respectively, compared to surface irrigation with an equivalent water volume of wick irrigation. In conclusion, the wick irrigation method, as a new method, can save water and improve seed yield and net income.

There is a stark yield gap between sub-Saharan African (SSA) potato productivity compared to other regions, leading to food security challenges. Hence, there is an immediate need to improve SSA potato yield. Research trials were under smallholder settings to determine effective management practices on the integration of selected potato cultivars, fungicides, mulch application, and different localities. Tested factors mulch application (mulch, not mulch), fungicide (sprayed and unsprayed) and different potato cultivars (Electra, Mondial, Panamera, and Sababa) were laid in a randomized complete block design in under five localities (Gobizembe, Hlathikhulu, Mbalenhle, Mbhava, and Stezi), and replicated three times over two consecutive seasons. Data collection included climatic data, emergence, days to flowering, plant height, physiological maturity, stem number yield, and yield components. Integration of Electra, fungicide (sprayed or unsprayed), and mulch application (mulch or not mulch) under humid, low atmospheric water demand, dominated by sandy soils and high-altitude locality had higher yields with the highest of 64.2 t ha−1 and a harvest index of 90.2%. In the locality that is on a south-facing slope, with the lowest altitude, clayed soils had the lowest yield of 13.4 t ha−1 from Mondial cultivar under unsprayed and no mulch. Electra cultivar showed consistent performance under different practices and yielded more across localities. Hence, it is recommended that effective management practices such as Electra together with fungicide (spraying or unsprayed) and mulch (mulch or not mulch) can be adopted to increase potato yield under rainfed conditions.
