Populations (Ecotypes) of Cyperus Alopecuroides Rottb. were collected from seven different sites of Punjab, Pakistan and evaluated for nutrients uptake under salt stress. For this purpose salt treatments (0mM, 100mM, 200mM, and 300mM) of NaCl were maintained under water logged conditions with four replicates. N% age increased in all populations with increase in salt level from 100mM to 300mM in growth medium. P value increased at medium level upto 200mM salinity but high level 300mM salinity decreased it. K value decrease with increase in salt level in growth medium in all populations. All populations responded differently at varying levels of salinity in uptaking of these nutrients. Maximum uptake of nutrients up to 200mM salinity showed their better adaptation under harsh saline environment.
