“…This difference might be due to the suitability of early sowing on un-compacted soil for Dagim variety, which contributed to maximum dry biomass yield. These results are in agreement with Desta et al [9] who reported significant difference in tef aboveground dry biomass yield when Kora variety was sown in early July. Moreover, Juraimi et al [10] reported that delaying of sowing time caused a decrease in biological yield in an experiment undertaken at Alem Tena (Central Ethiopia) that when sowing dates were delayed by 1 or 2 weeks, the biological yield was reduced by 35%.…”

Tef is the most cultivated crop in terms of area and second most produced crop after maize in Ethiopia. Soil compaction, inaccurate sowing date and shortage of high-yielding varieties are crucial problems in the study area. Therefore, this experiment was carried out during the main cropping season of 2021 to study the effects of soil compaction, sowing dates and tef varieties on yield and yield components of tef in Toke Kutaye district. The treatments included soil compaction (compacted and un-compacted soil), three sowing dates and three tef varieties such as [Dedefe (as standard check), Quncho and Dagim]. Treatments were factorially arranged and laid out in randomized complete block design with three replications. Analysis of the data indicated that days to 50% emergence, days to 50% panicle emergence, days to 90% physiological maturity and number of productive tillers of tef were significantly (P<0.05) influenced by main effect of soil compaction, sowing dates and varieties. Plant height, panicle length, total number of tillers, above-ground biomass yield, grain yield and straw yield of tef were significantly affected by the interaction of three factors. Highest plant height (124.26 cm), panicle length (36.26 cm), above-ground biomass yield (7.47 t ha-1), and grain yield (2.8 t ha-1) were recorded from un-compacted soil, in early sown Dagim variety. Therefore, farmers in the study area are advised to grow Dagim variety with July 15 sowing date without trampling the soil to improve tef production and yield. However, the experiment has to be repeated across locations and seasons to provide a reliable recommendation for improved tef production for similar agroecology.

“…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.

“…The increase in yield was significantly higher in the dry years than in the wet years [157]. After implementing no-tillage, positive soil promoting factors are expected to increase over time [158]. Analysis by Van Ittersum et al [159] showed that the initial application of no-tillage may have negative results at the start but long-term notillage has potential benefits such as reduced fertilizer demand and stable crop yields.…”

Taking sustainable agriculture measures is critical to effectively cope with the effect of the increasing population on water shortage. Straw mulching and reduced tillage are the most successful measures adopted in arid and semi-arid regions which affect crop production by changing the crop environment. This review focuses on the effects of tillage and mulching on the soil environment, including soil organic matter, soil moisture, soil temperature, soil microorganisms, soil enzyme activity, soil fertility, soil carbon emissions, pests, weeds, and soil erosion. In addition, water use efficiency and crop production are discussed under different tillage measures. Straw mulching can increase soil organic matter content, adjust soil moisture, and prevent water loss and drought; however, it can also lead to an increase in pests and diseases, and change the structure of the soil microbial community. Straw mulching can significantly enhance WUE (water use effectively) and yield. Reducing tillage maintains soil integrity, which is conducive to soil and water conservation, but could negatively impact crop yield and WUE. Precise field management measures, taken according to crop varieties and local conditions, not only ensure the high yield of crops but also protect the environment.
