Abstract: The fall armyworm (Spodoptera frugiperda), an invasive pest first reported in Ethiopia in 2017, has emerged one of the most serious threats to maize production. Its high reproductive potential, polyphagous, and rapid spreading capacity has led to substantial crop loss and economic damage in Ethiopia. Reliance on existing pest management strategies based on synthetic insecticides are proving increasingly unsustainable due to the costs, pest resistance, access to crop protection products, and environmental damage associated with pesticides. Push-pull technology (PPT) has emerged as an agroecological innovation based on cropping maize with repellent intercrops (e.g. Desmodium species) and trap crops (e.g. Brachiaria or Napier grass) can also help partially draw and trap FAW to some extent. Recent evidence (within the 2020 to 2025 period) indicated that PPT can reduce fall armyworm infestation, reduce crop loss/damage, effectively promote natural enemy populations, improve soil health/quality, and increase household resilience. This review presents evidence from Ethiopia and more broadly across East Africa to disentangle mechanisms and pathways for effectively (and ineffectively) implementing PPT in Ethiopian maize systems. The review highlighted the potential for PPT in Ethiopia for sustainable fall armyworm management but acknowledged the need for strengthened institutional support, improved seed systems, and better integration into climate-smart agricultural pathways to facilitate future adoption.

Abstract: Chickpea (Cicer arietinum L) production in Ethiopia is highly constrained by diverse biotic and abiotic stresses, and it is full genetic potential has not been exploited yet. Chickpea grain yield is one of the complex quantitative traits influenced by prevailing environmental conditions. As a result, multi-environmental yield trials are indispensable to detect wide adaptable and high yielding cultivars in the breeding program. To this end, a total of 12 advanced chickpea genotypes were evaluated against two standard checks (Arerti and Harbu) across two locations (Sinana and Ginnir) from 2019 to 2021 main cropping season. Pooled analysis of variance for grain yield showed significant differences t (p ≤ 0.01) among the main effects of genotypes and environments and (p ≤ 0.01) for G × E interaction effects. This indicates that either the genotypes differentially responded to the changes in the test environments or the test environments discriminated the genotypes or both. The first two principal components accounted for cumulative of 84.88% interaction effects, indicating that the majority of interaction effects were within two principal components. Additive Main effect and Multiplicative Interaction (AMMI) biplot enabled identification of adapted genotypes, G5 (FLIP-09-287C) and G2 (FLIP-09-155C). GGE biplot analysis suggested the presence of one mega environment and enabled identification of high seed yielding and broadly adapted genotypes G5 (FLIP-09-287C). Therefore, FLIP-09-287C can be released as wide adaptable Kabuli type chickpea variety for potential growing areas of Bale and East Bale as well as other similar agro-ecologies.
