“…Therefore, germination is reduced or slowed with increasing salinity, which was observed within this study. This pattern of germination has also been observed in several Eragrostis species, such as E. plana (Bittencourt et al 2017), E. tenella (Chauhan 2013), and teff [Eragrostis tef (Zuccagni) Trotter] (Papastylianou et al 2019). In contrast, some plants can develop over time to produce seeds that withstand a greater salt tolerance as a result of a difference in genetic variation or adaption to localized climatic conditions (Dehnavi et al 2020).…”

African lovegrass [Eragrostis curvula (Schrad.) Nees] is a highly invasive C4 perennial grass that threatens global biodiversity. Appropriate management of the species has been hampered by a lack of knowledge of the species’ seed ecology, resulting in significant economic and environmental impacts within various environments. Consequently, this study explored the effects of a selection of environmental factors (photoperiod, alternating temperature, pH and salinity) by analysing several measures of germination on four geographically distinct populations of E. curvula to assist in its extirpation from infested sites. Seeds were collected in Australia from Maffra and Shepparton, Victoria; Tenterfield, New South Wales and Midvale, Western Australia. Key results showed that seeds from Maffra (54% vs. 79%), Tenterfield (38% vs. 61%) and Shepparton (34% vs. 71%) had significantly reduced germination in complete darkness compared to an alternating 12 hours light and 12 hours dark photoperiod, whereas Midvale had consistent germination (91% vs. 99%). Temperatures between 17/7 OC reduced germination for Maffra (42% vs. 73%), Tenterfield (34% vs. 55%) and Shepparton (33% vs. 59%) compared to the mean of all other temperature combinations, whereas, Midvale had consistent germination. Furthermore, germination for all populations was consistent between pH 4 and 9. For salinity, germination was significantly reduced at ≥100 mM for Maffra (29% vs. 67%), ≥150 mM for Tenterfield (29% vs. 94%) and Shepparton (39.5% vs. 81.5%), and 250 mM for Midvale (39% vs. 82%) compared to the mean of all other concentrations. Although each trial was conducted independently, they can be used to generate species targeted management. Such strategies include maintaining high levels of quarantine and hygiene programs to avoid future spread, where practical apply light-limiting strategies (mulching, tilling or scraping) for the Maffra, Tenterfield and Shepparton populations; and maintaining management efforts year round as the species can germinate under a wide range of conditions.

Abstract. This review article aims to summarize global studies relating to the distribution, biological characteristics, productivity and cultivation technology for grain and green mass from teff (Eragrostis tef). Teff has the shortest vegetation period among cereals, good adaptability to varied environmental conditions and high drought resistance. In the world, it is gaining popularity as a healthy grain food, especially suitable for people suffering from celiac disease, due to the lack of gluten in the grain and a good source of omega fatty acids, vitamins and minerals. Teff is the crop with the shortest vegetation among the cereals – it ripens for 50 to 90 days. It can successfully be sown as a second crop following early cereals. As fodder, it has good nutritional value compared to some basic fodder crops. It is used as food for ruminants and horses, compared to the quality of well-maintained natural grasslands. Straw is preferred more than that of the basic annual cereal crops in ratios as coarse fodder. Its application in industry is also feasible. Resistance against diseases and enemies, as well as the ability to choke weeds, makes it an economically efficient and ecological crop. While studies on teff in Bulgaria are limited, they indicate successful cultivation in the arid conditions of Southern Dobrudzha. This crop, unknown to our producers, could be included in the structure of field crops and take up areas that are not suitable for the traditionally grown cereal plants – wheat, barley, maize. For this purpose, it is necessary to study the impact of the climate at a local level on the development and productivity of teff. It is necessary to pay serious attention when choosing the production technology, in order to use the potential for the production of green mass and grain, and a possible choice for impact is the optimization of the seeding rate and fertilization.
