The Altiplano of Bolivia faces droughts and frequent frosts due to climate change, which affect yields and productivity of vegetables. Pro Rural, together with the Technical University of Oruro, has developed and implemented Biointensive Agroecological Family Units (UFABs) as an alternative to family agricultural production in the Altiplano, characterized by the efficient use of water, improving soil properties through localized fertilization and the substitution of agrochemicals for agro ecological inputs. The objective of this research was to determine two agricultural production systems on agronomic parameters of six vegetables. An experimental area was established in a factorial arrangement arranged in a randomized complete block design with six treatments (vegetable species) and two production systems (biointensive and traditional system), drip irrigation in the biointensive system and flooding in the traditional system. According to the results obtained on agronomic parameters, there is a statistical difference in yield and agronomic variables (plant weight, root length, and plant height) showing a superiority in the biointensive system, similar results are seen in leafy vegetables, the volume of water consumed shows that there is greater efficiency in the use of drip irrigation system with 90%, the amount of soil microorganisms is more than 50% in the biointensive system, similar results are seen in the chemical analysis of the soil.
