The lentil (Lens culinaris Medik) crop is of great interest throughout the world, mainly in developing countries, since it has a high content of proteins, carbohydrates and essential minerals to meet the needs of the human diet. However, it contains antinutrients that bind to proteins and minerals resulting in decreased absorption and bioavailability, likewise its concentration in the plant increases when stressful environmental conditions occur. The objective of this work was to determine the nutritional yield potential of lentil varieties in 3 contrasting environments. As experimental material, 12 varieties of lentil (8 macrosperma and 4 microsperma) with good agronomic characteristics from the Grain Plant Breeding Program of the Faculty of Agricultural Sciences, UNR, including the commercial tester Silvina were used and were sown in the following environments: growth chamber (GC), field in 2020, and field in 2021. The experimental design for the 3 environments was a randomized complete block design (DBCA) with two replicates. The GC consisted of a hydroponic system with a photoperiod of 20 hours of light provided by LED tubes, a temperature of 23± 2°C, constant supply of nutrients and perlite as a substrate, each repetition consisted of a multipot with 30 plants per genotype. In the field, each repetition consisted of 2m plots with 50 plants planted per genotype at the beginning of July. The year 2020 presented temperatures above 30 °C and daily rainfall greater than 40 mm of water during the critical period of cultivation and grain filling. The following traits were evaluated: % protein (P), % phytic acid (AP), % phenols (PH) and % tannins (T). An ANOVA was carried out using the infostat program, which showed a significant genotype-environment interaction (p
