“…For example, at the S4 salinity level decreased water application (S4W4) resulted in a nonsignificant loss of 5% yield, relative to control water content (S4W1), in contrast to a 36% reduction in yield with decreased water application under low salinity ((S1W4) relative to control water content (S1W1)). In line with this result, if there is water stress, one may wrongly conclude that the quinoa plant has tremendous salinity tolerance since there is no yield reduction under increasing salinity, but this is not correct e.g., Aly et al (2018).…”

We studied the responses of quinoa (Chenopodium quinoa Willd.) to single and combined effects of four different irrigation water salinity (electrical conductivity) levels (S1: 0.25, S2: 5, S3:10 and S4: 20 dS m− 1), and four water application rates (W1:120%, W2:100%, W3:70% and W4:50% of depleted water from field capacity), in a fully randomized factorial design with total of 48 weighted lysimeters. Seed yield was 30% higher when water requirement was fully met (W1 and W2) as compared to treatments where water requirement was partially met (W3 and W4). Crop water response coefficients were found sensitive (Ky= 1.55) to drought induced water stress but tolerant to salinity induced water stress (Ky=0.47). We found that quinoa had a salinity threshold value of ~ 4 dS m− 1 (in soil extract) with a slope of 3.4%, (yield loss per dS m− 1 increase in salinity) which is classified as moderately salt tolerant crop. We evaluated the combined effects of salinity and water levels on seed yield, concluding that if there is more than one stress factor, the crop will respond to the stress factor having the highest impact (either salinity or water stress). Seed yield under combined salt and water stress for all treatments was well predicted from the separate responses to water and salt stress using the dominant stress response model. Our results indicate that over the range of conditions studied, quinoa water productivity was more dependent on applied water rate than on salinity.

“…Quinoa is also known for its ability to grow in marginal environments and tolerate a range of adverse growth conditions, such as high salinity [ 14 , 15 , 16 , 17 ], heat [ 18 ] and drought [ 15 , 19 , 20 ]. Detailed studies of quinoa subjected to drought stress have been conducted, both in the field and in greenhouse experiments, providing insight into the key physiological adaptations of quinoa.…”

Quinoa (Chenopodium quinoa Willd.) is a genetically diverse crop that has gained popularity in recent years due to its high nutritional content and ability to tolerate abiotic stresses such as salinity and drought. Varieties from the coastal lowland ecotype are of particular interest due to their insensitivity to photoperiod and their potential to be cultivated in higher latitudes. We performed a field experiment in the southern Atacama Desert in Chile to investigate the responses to reduced irrigation of nine previously selected coastal lowland self-pollinated (CLS) lines and the commercial cultivar Regalona. We found that several lines exhibited a yield and seed size superior to Regalona, also under reduced irrigation. Plant productivity data were analyzed together with morphological and physiological traits measured at the visible inflorescence stage to estimate the contribution of these traits to differences between the CLS lines and Regalona under full and reduced irrigation. We applied proximal sensing methods and found that thermal imaging provided a promising means to estimate variation in plant water use relating to yield, whereas hyperspectral imaging separated lines in a different way, potentially related to photosynthesis as well as water use.

“…Additionally, DI may increase the quality of yield and grain size (Dorji et al 2005;Nakawuka et al 2017), reduce fungal diseases risks (Guilpart et al 2017), reduce nutrient leaching through root zone, improve groundwater quality and decrease the need for additional fertilizer applications (Brar et al 2018;Carlton et al 2016;Jonubi et al 2018). In these ways, deficit irrigation with saline water could present a solution for decreasing environments risks by reducing drainage water, while also promoting food and freshwater security (Aly et al 2018;de Melo et al 2018;Muschal 2006). However, a reduction in the volume of water used for deficit irrigation also limits the amount of leaching that can occur, thus potentially promoting salt accumulation in the soil (Glenn et al 2009).…”
