Salinity affects plant growth by causing physiological and morphological changes, which reduces its vegetative system. This appears through decreases in stem length, number of leaves, as well as lateral branches and diameter of plant organs.There are two types of salinity: soil salinity and water salinity. Soil salinity means soil characterized by a high percentage of dissolved salts, mostly of which are chlorides, sulfates and carbonates, to a degree harmful to plant growth. If the soil contains dissolved salts in high quantities, water potential can be reduced to negative level. A distinction between salt stress and ionic stress must be noticed. The first term is used when salt concentration is so high that water potential of growing substrate drops to a significant level (05.0 - 1.0 MPa). If the decrease in water potential was slight and undetectable, the effect here is in the form of ionic stress. A simplified definition of salt stress can be given as an increase in the concentration of salt in plant cells to the degree that affects the physiological properties. This is due to a decrease in the water potential of growing substrate which negatively affects the morphological characteristics of plant. Water potential determines the water movement from the soil to the root or from one cell to another.

“…Germination, emergence, and early seedling growth are salinity sensitive stages of crop development (Jamil et al, 2005). Salinity disrupts crop establishment by decreasing the germination percentage and delaying seedling emergence (Siddiky et al, 2014) and decreases the yield at a later stage (Rahman et al, 2018). Excessive uptake of ions causes toxicity, and reduced water availability between the seeds and the outer environment thereby inhibiting primary root emergence (Delachiave & dc-Pinho, 2003).…”

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.

“…As a result, salt stress affects the growth and development of plants, thus reducing their yield (Arzani and Ashraf, 2016) [2] . Salinity disturbs crop establishment by decreasing the germination percentage and delaying seedling emergence (Begum et al, 1996, Siddiky et al, 2014 [3,4] . Salinity affects plant growth by disturbing water balance, creating an imbalance in plant nutrition and affecting plant physiological and biochemical process (Yeo et al, 1985, Karim et al, 1993) [5,6] .…”

Salinity is one of the most important abiotic stresses limiting yield potential. Salinity is even more harmful to seed germination and seedling development. The present study aimed to evaluate the effect of the salinity on germination and seedling growth in four different vegetable crops viz., tomato, chilli, cucumber and bhendi. In this study, germination percentage (%), shoot length (cm), root length (cm), root to shoot ratio, fresh and dry weight (g) were recorded at four different salinity levels (50 mM, 100 mM, 150 mM and 200 mM NaCl) and one control (0 mM NaCl). Significant differences were observed in all the traits in all crops in this study. Based on the germination percentage, by comparing the four crops, cucumber had the highest tolerance to the salinity which was followed by bhendi. The crops of tomato and chilli were more sensitive to salinity.
