Effect of Na2SO4 Salinity on Brinjal (Solanum melongena)

Abstract

Soluble salts are present in all soils and irrigation water, which are essential and required for normal plant development and growth. The design used for the experiment is CRD with three replicates with three different treatments of Na2SO4, was conducted to check the effect of salinity on plant growth. After 14 days interval it was observed that different replicates showed different morphological growth parameters due to application of Na2SO4. Results showed that replicates with maximum salt concentration i.e. that is 60 ppm Na2SO4 gave best growth which showed that maximum salt stress for Brinjal was good enough for growth and stress showed positive response on the plants with 60 ppm Na2SO4.normally salinity stress in excess is harmful for plant growth but our experimental observations showed that our Brinjal specie was salt tolerant. Plants bore the salt stress upto 60 ppm Na2SO4. It was examined that this tolerance limit was not harmful and not acted as stress on Brinjal spp. Infact it favored the plant growth. Discrepancies and inconsistencies can also exist there in some of information due to difference in environments, cultivars and experimental conditions.
