Evaluating Growth and Yield Parameters of Five Quinoa (Chenopodium quinoa W.‎) Genotypes Under Different Salt Stress Conditions

Soil salinization is a global problem which restricts the choice of crop for cultivation.‎ Management and reclamation of salinity using costly techniques may not be affordable by subsistence farmers.‎ Therefore, it is important to look for new alternate crops like “quinoa” which are more salt-tolerant.‎ As crops vary in their tolerance to salinity, they need to be evaluated for different salinity conditions.‎ This study was conducted to evaluate five quinoa (Chenopodium quinoa W.‎) genotypes (ICBA-Q1, ICBA-Q2), ICBA-Q3, ICBA-Q4 and ICBA-Q5) for salinity tolerance under four artificially induced salinity (5, 10, 15, 20 dS m-1) levels.‎ The pot trials were conducted in a greenhouse, using 6 kg of Fluvisol soil in each pot.‎ For comparison, trials were also conducted under field conditions.‎ The parameters studied were rate of seed germination, plant height, fresh and dry biomass, chlorophyll content and grain yield.‎ As expected, salinity had generally an inhibitory effect on all parameters.‎ Out of the five quinoa varieties (ICBA-Q1 to ICBA-Q5), ICBA-Q3 and ICBA-Q4 proved to be more salt-tolerant.‎ Therefore these two genotypes are recommended to farmers for large-scale adaptation.‎
