The results showed that the height number of tillers at various intervals oil content fresh and dry weight of herb yield chlorophyll content N;P;K; Ca and Fe declined at higher concentration of RSC i.e. 15meL-1 levels except Na which tremendously reduced.the treatment R3 G0 having 15 meL-1 sodic water without chemical amendment resulted marked reduction in oil production,chlophyll content and N,P,K, Ca and Fe uptake in comparison to other levels of RSC wather in association with concentration. Presence of higher amount of CO3-- and HCO3- ions in irrigation or soil solution increased the sodium adsorption on soil and thereby precipitates Ca++ and Mg++ as their carbonates.therefore solution- having bicarbonates in excess of Ca++ and Mg++ ion will have residue of NaHCO3 upon evaporation and thereby increased the ESP and pH of the soil.
