What is it about?
The tolerance of plants to salinity stress varies during different growth stages. Knowing the tolerance of each plant during its growth helps to a better irrigation management by saline water so that the least yield reduction occurs. When salinity of water is up to 8dSm-1 quinoa can establish without significant reduction. Although after establishment and until flowering irrigation can be performed by 20dSm-1 saline water without significant reduction in number of flowers and for obtaining the best yield of seed weight, it's better to irrigate quinoa with water salinity up to 15dSm-1 in the period between flowering and seed filling.

Why is it important?
Salinity of soil and water resources is an increasing problem all over the world. In this situation using saline resources for agriculture production is an unavoidable issue. The economic exploitation from saline resources is possible if they are used by a proper management. The best management is possible by a distinctive knowledge about the plant cultivated in such a situation and the most important issue about the plant is its tolerance to salinity. The salinity tolerance not only is different among different plants and species, but also varies during growth of a particular plant. So, for the best management of irrigation by saline water it is of a particular importance to know the salinity tolerance of plants during their various stages of growth.
Perspectives
Working on quinoa as a high nutritional value halophyte, which can bring food security using saline resources was a great experience. Current article maybe a good guide for those who want to cultivate quinoa using saline resources to have the most economic yield and to produce a valuable food from the saline soil and water resources which many other plants cant be cultivated.
