Introduction: Amaranthus sp. can be used as a cereal for grains, or as a vegetable for leaves, and it has great potential as fodder plant. It has high content of protein, carbohydrates and fats. Aims: The experience aims to test the productivity of some varieties of Amaranthus sp., in order to integrate successfully in agricultural technologies, varieties like Amont Golden Giant, Hopi Red Dye and Plenitude, in the climatic conditions of Teius, Alba district. Materials and Methods: The results obtained describe experimental culture founded near the town of Teiuş area, positioned in the central eastern Alba district. The average annual temperature is 9,7o C with maximum values recorded in July. In the experiment four species of Amaranthus were used: Amont (Amaranthus cruenthus), Golden Giant (Amaranthus hypochondriacus), Hopi Red Dye (Amaranthus hypochondriacus), Plenitude (Amaranthus hypochondriacus). The experimental design is of trifactorial type (2x3x4), placed in three repetitions. Results: The analysis of productions had in view the interpretation of the values determined and obtained depending on the individual influence of tehnological factors considered, as well as on the influences caused by the interaction of factors. The Plenitude sort records the greatest production increases, 1344,99 kg/ha, in irrigation conditions, whereas the Golden Giant sort, in irrigation conditions, records a decrease in production of 360,73kg/ha. Conclusion: Variety Plenitude recorded the highest increases (60.2%) under irrigation, and the Golden Giant sorts, under irrigation conditions, recorded a decrease of 15.2% of production. The fertilizer complex brings no significant increase of production at the Hopi Red Dye sort, and in the case of the sort Plenitude the fertilizer intake decreases production with 54.41 kg / ha if fertilized with the complex (NPK), and 972.56 kg / ha when fertilized with organic stable manure.
