  1. International Quinoa Conference 2016: Quinoa for Future Food and Nutrition Security in Marginal Environments Dubai, 6-8 December 2016 www.quinoaconference.com The Study of Quinoa Salinity Tolerance in the Field Conditions By: Mohammad Shahid and N.K. Rao International Center for Biosaline Agriculture, Dubai, UAE email: m.shahid@biosaline.org.ae

  2. UAE geography  situated in south eastern corner of the Arabian Peninsula  a relatively small country with an area of 83, 600 square km  most of the country is desert which is part of a vast sea of sand called Rub’ al Khali or Empty Quarter

  3. Agricultural problems in the UAE  Limited cultivated land  Most of the country is comprised of desert  Small area for agriculture farming is available. Fewer water resources  Annual rain is less than 120mm (4.7 inch) in most of the areas  Most of the ground water is brackish, which is not suitable for majority of crops

  4. Challenges  To find crops which can be grown in such harsh environments with limited amount of fresh water  Apart from other crops, QUINOA was tried in the United Arab Emirates to see its potential as food and feed  Evaluation of the performance of selected genotypes of quinoa for their productivity on different qualities of irrigation water.

  5. Exper perimental Si Site Experimental site • The experiment was conducted at the International Center for Biosaline Agriculture (ICBA), Dubai, United Arab Emirates • 25°05.794 N • 055°23.386 E

  6. Soi Soil T Type Soil type • The soils at ICBA experimental fields are sandy in texture, that is, fine sand (sand 98%, silt 1%, and clay 1%) • Calcareous (50–60% CaCO3 equivalents) • Moderately alkaline (pH 8.22). • Saturation percentage of the soil is 26 and has very high drainage capacity • Electrical conductivity of its saturated extract (ECe) is 1.2 dS m − 1 .

  8. Planting Planting  Each set of accessions was sown in randomized complete block design (RCBD) in three replications  Two water treatments (0 dS/m and 15 dS/m)  Plot size was 2.5 x 2 m  The seeds were sown manually by dibbling 3-4 seeds into the soil to a depth of 1-2 cm close to the dripper  After sowing, field was covered with Acryl sheet

  9. Irrigation Irrigation • A drip irrigation system was used • with a spacing of 50 cm between the laterals • 25 cm between the emitters has been installed in all of the experimental farms. • water was applied for 15 min @ 4 L/h

  10. Fertilizers Fertilizers • Organic manure was applied before planting @ 40 tons/ha • Urea (46%) @ 30 kg/ha • NPK @ 30 kg/ha

  11. Study Study The growth performance and yield potential of the 20 quinoa accessions was evaluated based on the study of different characteristics including

  27. Conclusions • Five of the quinoa lines (ICBA-Q1…Q5) developed at ICBA performed better than the other accessions. • Their performance was superior both at low and high salinity • These lines have the potential to be grown in the similar type of regions with saline water of up 15 dS/m • Salinity treatment increases the Na concentration in the quinoa seeds up to 400%
