A Study on Effects of Salinity on Growth and Yield of Tomato Genotype (Solanum lycopersicum)

Saline water occupies 71% of the Earth area. It is thought that even a quarter of the whole pedosphere is affected by salts amounting to 950 x 106 ha while 23 % of the 1.5 x 109 ha cultivated land is considered as saline. This study was carried out to investigate the influence of salinity on the on growth and yield of tomato genotypes. The seedlings 20 genotype were divided into three groups, Sodium chloride (NaCl) dissolved in irrigation water to make variant concentration of 30, 60 mg/L of salt concentration using E. C meter which were used to water the plants. Vegetative and reproductive characterization was evaluated. Data obtained were subjected to one way analysis of variance using SPSS (20) Statistical Software. All the genotypes exhibited a decline significantly in vegetative and reproductive parameters measured, with increasing salt concentration. In conclusion, the result of this research suggest that salinity decline both vegetative and reproductive parameters in tomato.
