The effect of deficit irrigation and fertilizer on quantitative and qualitative yield of quinoa (Chenopodium quinoa)

In order to investigate the effect of deficit irrigation and chemical fertilizers on yield some physiological traits quinoa an experiment was conducted in 2019 as split plot based a randomized complete block design two locations (Mashhad Neishabour). Irrigation included, I0: full irrigation, I1: no at emergence stage, I2: stem elongation I3: flowering I4: seed setting stage. Fertilizer treatments included control (no fertilizer application); application according local practices; manure 10 tons; 20 tons per hectare. general, yield, percentage protein oil Mashhad higher than Neishabour. I2 treatment had least negative relative leaf water content. Application fertilizers, animal increased percent by 1.43, 1.66 2.37 compared control, respectively. The highest (5.91%) obtained for lowest (4.18%) I4 due I1 observed Neishabour related I0 with Mashhad. results showed that stress tolerance potential can be modified source location.
