The objective of the study was to characterize the nutritional quality of the quinoa silage (Chenopodium quinoa willd) yellow variety of marangani with the addition of efcient microorganisms in rela- tion to the age of quinoa and the diferent periods of silage fermentation. The quinoa plant material (leaves and stems) was collected, three cutting ages were evaluated: 60, 90 and 120 days and four periods of silage fer- mentation: seven, fourteen, twenty one and thirty days. Four treatments were performed: treatment 1 (T1) refers to the control without applying any type of MS, treatments T2, T3 and T4 were applied MS at the dose in- dicated on the label as silage additive, each treatment was performed in triplicate . The plant material was dehydrated for a period of 5 hours and subsequently the quinoa foliage microsyls were made. The nutritional value (dry matter, neutral detergent fber, acid detergent fber, ash and crude protein) was determined to the foliage and quinoa microsilos. A completely randomized design (DCA) with an arrangement of time-divided plots was used, an analysis of variance was made using the Mixed Linear Model and a separation of means by the Duncan method and a correlation of Pearson variables. For the humidity variable, a range of 81,3 – 87,7% was found for T1 and a range of values of 57,3 – 90,3% for the other treatments. The ashes were maintained in values similar to the quinoa foliage in relation to the diferent ages of regrowth, the highest percentage of ashes was obtai- ned at 21 days of silage fermentation with a value of 20,3% for T3 with the silage of Quinoa foliage 90 days of regrowth; while the crude protein content decreased slightly in relation to T1 in the 120-day regrowth age, presen- ting signifcant variations between treatments with values of 11,3-17,3%. A directly positive proportion directly proportional (P≤0,01) was presented
