“…The short-term impact of RT on teff in our study might be linked to the immediate benefits afforded by improved soil moisture compared to that obtained with CT (Figure 4) because one of the major bottlenecks of rainfed teff production is the shortage of moisture immediately after planting and at flowering time [52]. In agreement with our present findings, Gezahegn et al [53] and Desta et al [54] have both reported that RT increased crop yield in the short term. However, others have reported a reduction in crop yield in the first 2-3 years of using RT [55].…”

Teff is an important crop for smallholder farmers in Ethiopia. Improved crop management practices are needed to increase teff productivity and decrease production costs. Here, we used a split–split plot design to evaluate the impacts of different tillage, sowing, and soil compaction practices, and their combinations, on agronomic performance, weed population, lodging, and cost in teff production in the northwestern highlands of Ethiopia in 2018–2020. Reduced tillage (RT) improved soil moisture, resulting in increased agronomic performance and decreased production costs compared with conventional tillage (CT); however, the weed population was substantially larger with RT than with CT. Row planting (RP) reduced seed cost and lodging but increased sowing and weeding costs compared with broadcast planting (BP). Plant population and leaf area index were substantially greater with BP than with RP during early-stage growth, but this reversed during late-stage growth. Despite labor costs being significantly greater with (WC) compaction than without (NC), little to no differences were observed in the weed population or in agronomic performance. Partial cost–benefit analysis revealed that RT–RP–WC followed by RT–RP–NC was the most economical treatment combination, suggesting that RT–RP–NC could be a labor-effective means of increasing teff production by smallholder farms in Ethiopia.

“…Its Page 2 of 16 Woldeyohannes et al CABI Agriculture and Bioscience (2022) 3:27 current average productivity is well below its genetic potential: improved cropping technologies in non-lodging conditions can result in yields exceeding 4.5 t ha −1 (Tefera and Ketema 2001), more than double the national average (Central Statistical Agency 2018). However, teff yield potential can be fully achieved only when applying appropriate sowing and plant curation (Ben-Zeev et al 2020;Mihretie et al 2021;Bogale et al 2013), management of soil fertility (Wato 2019), and appropriate agronomic practices (Gezahegn et al 2019;Berhe et al 2013) including weed management (Rezene and Zerhun 2000) and pest management (Gemechu Degete 2021;Gyan et al 2020).…”

Value of teff (Eragrostis tef) genetic resources to support breeding for conventional and smallholder farming: a review

et al. 2022

View full text Add to dashboard Cite

Crop germplasm collections are a key asset to support the resilience and productivity of cropping systems worldwide. In their diversity lays an oftentimes untapped reservoir of alleles that may enable breeding strategies targeting local adaptation, resulting in enhanced performance and higher varietal uptake. In the past five decades, the national genebank of Ethiopia actively collected and conserved thousands of teff (Eragrostis tef) accessions, a staple crop throughout the Horn of Africa at the basis of countless cultural uses and with high market relevance. This review article emphasizes the breeding significance of teff genetic resources, highlighting current challenges in teff farming and improvement that could be addressed further valorising germplasm collections. We collect data generated on the largest teff ex situ collections in the world to discuss opportunities to improve teff tolerance to stress and lodging, as well as to increase its productivity across its cropping area. In doing so, we highlight and critically revise current and past literature tapping in teff diversity to support teff improvement. This review starts providing a summary of teff characteristics, detailing the status and challenges of teff cultivation and breeding. It then follows describing the diversity existing in teff diversity collections and its relevance for teff improvement. The review concludes describing the molecular studies undertook on teff in the past two decades, highlighting the perspectives of molecular breeding for teff. The body of knowledge available on teff shows that there is large potential for improvement of this crop to target smallholder farming systems as well as international markets, and that improvement may start from the large diversity available in teff collections.
