“…This is due to the effects of high osmotic potential and specific ion toxicity (accumulation of Na + and Clions) (Khan & Weber, 2008). The present findings are in line with previous reports on the mean germination rate (Cunhua et al, 2012;Sardoei & Mohammadi, 2014), speed of germination (Nasrin & Mannan 2019), germination energy (Nasrin & Mannan, 2019) and mean germination time (Chakma & Hossain, 2019) of the tomato seeds. Salinity notably affects germination in many species but also increases the time required to complete germination (Nawaz et al, 2011).…”

“…This indicates that the Sirinka variety is more sensitive to salinity than the other varieties. The combined effect of variety and salinity had a significant effect on the mean germination rate (Cunhua et al, 2012;Sardoei and Mohammadi, 2014;Moles et al, 2019), mean germination time (Sholi 2012;Chakma & Hossain, 2019), speed of germination (Nasrin & Mannan, 2019;Moles et al, 2019) and germination energy (Nasrin & Mannan, 2019), which supports the findings of this study.…”

“…Roma VF had the lowest first day of germination and the highest germination index. According to different authors, tomato varieties respond differently to total germination percentage (Sardoei & Mohammadi, 2014;Chakma & Hossain, 2019;Moles et al, 2019;Nasrin & Mannan, 2019) and germination index (Chakma & Hossain, 2019) which supports these findings. These observed variations in seed germination responses over different salinity levels indicate the different behaviors of individual tomato varieties.…”

“…Salinity in agricultural soils refers to the presence of a high concentration of soluble salts in the soil moisture of the root zone (El-Zanaty et al, 2006). Currently, it is one of the most severe abiotic factors in many agronomic and horticultural crops (Nasrin & Mannan, 2019). This resulted in a reduction in cultivated land size, crop productivity, quality and biomass, especially in arid and semi-arid irrigated areas (Shahbaz & Ashraf, 2013).…”

“…The management of saline conditions in the fields and greenhouses would be expensive and temporary, while the selection for salt tolerance is a wise solution to minimize salinity effects and improve production efficiency (Nasrin & Mannan, 2019). Screening of varieties during seed germination is commonly used because the process is rapid and is easily…”

Salinity adversely affects 20-30% of the irrigated area in the world. Tomato is sensitive to salinity. It is one of the most severe abiotic factors of many agricultural crops and it becoming the main problem in Ethiopia. This study was conducted to evaluate the effects of different salinity levels on the seed germination parameters of tomato varieties. It was laid out in a completely randomized design with three replicates. The treatment included four tomato varieties (Sirinka, Weyno, ARP D2, and Roma VF) and five salinity levels (1 dS m-1, 2 dS m-1, 3 dS m-1, 4 dS m-1, and control). Fifty seeds were placed in a Petri dish over a moistened germination paper for germination and seedlings and allowed to grow for 14 days. The germination rate, speed and energy of tomato seeds were significantly (p < 0.001) affected by the combined effect of variety and salinity. The shortest mean germination time, the highest mean germination rate, and the highest speed of germination were recorded in the ARP D2 variety in the control treatment. The lowest first and last days of germination, and the uncertainty of germination were recorded from ARP D2. However, an increase in the days of germination and in the uncertainty of germination, and a decrease in the germination index and total germination percentage trends were observed with increasing salinity levels. The highest level of salinity (4 dS m-1) affected the germination of tomato varieties. Among the four tested tomato varieties, ARP D2 and Roma VF were tolerant to salinity.
