Variability in response of Chickpea (Cicer arietinum) to salt stress on enzymatic activity
Soil salinity adversely affects majority of biochemical processes in plants. In the present study, the enzymatic activity at different levels of electrical conductivity in soil was studied in Chickpea (Cicer arietinum), in order to understand the mechanism of salt tolerance and evaluate the effects on the yield. Salinity was found to inhibit the activity of both Nitrate reductase as well as total nitrogen. Whereas nitrite reductase and nitrogenase were observed to be incensed in their activity. The study with sodium chloride salinity was chosen as the North belt of Uttar Pradesh (India) was found saline. Saline ground water and soils are dominated by either chloride or sulphate salts. The chemical analysis of soil and plant samples collected from a range of sites at Rohilkhand, India indicated that the enzyme activity in Chickpea was more sensitive to chloride-dominated saline water irrigation as compared with sulphate-dominated.
