ABSTRACT The production of hydroponic forage or cultivation without land would ensure a constant source of food very homogeneous in volume of biomass and nutritional quality, improving the health condition, vitality and fertility of livestock. The objective of the research work was to evaluate the effect of aerobic liquid organic fertilizer on the production of bio-hydroponic green forage in two varieties of oats (Avena sativa L.). The research was carried out in the Cota Cota experimental center, belonging to the Faculty of Agronomy - UMSA. The completely randomized design (DCA) was used with a bifactorial arrangement. Evaluating two varieties of oats; Seagull and Creole, with four doses 0% (only water), 10%, 20% and 30% of AOLA. In the yield of green matter, the gull variety had the highest value with 2.65kg / 0.25m2 and the Creole variety with 2.10 kg / 0.25m2. For the dry matter content, the maximum value was 21%, corresponding to the treatments V1D0 (gull variety-only water), V1D1 (gull variety 10% AOLA) and V2D2 (Creole variety 20% AOLA). Regarding the effect of AOLA on the nutritional content of FVBH-A. the highest value of crude protein was 13% correspond to V1D2 (gull variety - 20% AOLA), V1D3 (gull variety - 30% AOLA), V2D1 (variety criolla-10% AOLA) and V2D3 (variety Creole-30% AOLA); the highest content of organic matter was 96% corresponding to the treatments V2D0 (Creole variety - only water), V2D1 (Creole variety -10% AOLA) and V2D2 (Creóle variety - 20% of AOLA); in the amount of ash the highest result was 5%, which corresponds to the treatments V1 DO (variety gull-only water), V1D1 (variety gull-10% AOLA). In the economic analysis, it is established that the treatment V1D1 (variety seagull-20% AOLA) with a B / C of 1.13 is more profitable.
