Abstract:An experiment was conducted at general commission for scientific agricultural research, Petima research center, during the 2022-2023, to study the effect of four irrigation tretments (I0: rain fed agriculture, I1: two flag, I2: three flag,I3: complete irrigation) on some morphological traits and productivity of three varieties of Quinoa (V1: Q26; V2: Gieza ; V3: Zer. 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. the complete irrigation treatment (I3) excelled in the following traits the plant length(99.56cm), weight of the thousand seeds(2.63gr), the seed weight per plant(29.33gr ( and the seed yield (3519kg.ha-1), while the supplementary irrigation treatment (I1) excelled in the number of othkul per plant(16.22) othkul.plant-1, number of plants per area (12 plant.m-2), the varieties Q26 (V1) excelled in productivety traits and achieved the highest average in weight of a thousand seeds trait (2.60gr), the seed weight per plant trait(28.16.gr) and the seed yield trait(3328kg.ha-1),. the interaction between the variety Q26 and irrigation treatment (I3)with complete irrigation gave the highest average for the following traits: plant length (108.67cm),number of plants per area(12plant.m-2), seed weight per plant(33.78gr), and the seed yield(4053kg .ha-1).
Keywords: Quinoa, irrigation, varieties, productivity.
