An experiment was conducted at the agricultural scientific research center in Petima, Damascus Countryside Governorate, during the 2022-2023 planting season, to study the effect of four irrigation trials (I0: rain fed agriculture, I1: two flag, I2: three flag,I3: complete irrigation) according to five fertilizer trials (F1: Recommended mineral fertilizer; F2: half the fertilizer recommended dose+ spray algae 1extracts1.5kg .ha-1 + spray humic acid 2k.ha-1,F3: half the fertilizer recommendation+ spray humic acid 2 kg .ha-1,F4: half the fertilizer recommendation+ spray algae fertilizer 1.5kg .ha-1,F5:spray algae fertilizer1.5kg .ha-1 and humic acid1.5kg .ha-1) in some growth and productivity traits for Quinoa Zer model. The experiment was designed according to a randomized complete block design (RCBD) in the order of the split blocks, with 3 replications. The results showed significant differences between the studied treatments and their interactions. Where complete irrigation (I3) excelled in developmental traits and achieved the least of main width panicle (6.00cm), weight of seeds per plant(31.56gr.plant-1), seed yield (5246kg.ha-1)and the bio-yield (8987kg.ha-1), supplement irrigation,(I1)excelled in developmental traits and achieved the plant length(87.26cm), main length panicle (20.39cm) , thousand seeds(2.60gr), while fertilization treatment (F2)excelled in all productive traits and achieved the highest plant length(92.25cm), main length panicle (21.24cm), main width panicle (5.62cm),weight of seeds per plant(35.24gr. plant-1) and the weight of a thousand seeds(2.72gr).the seed yield(4145kg.ha-1), and bio-yield(8900kg.ha-1).While for the interaction of the studied treatments, cultivation by complete irrigation (I3)with the application of fertilization treatment(F2)gave the highest average main width panicle(7.00cm), weight of seeds per plant(52.4gr.plant-1), seed yield (5947kg .ha-1), and the bio-yield (1200kg.ha-1).
