The main problem of the agricultural production in arid and semiarid regions is mainly the scarcity of irrigation water and the low quality of the soils. Hence, it is important to find alternatives and efficient water resources management practices in these regions within a frame of absolute rationality and sustainability. The objective of this work was to assess the water retention capacity of acrilamyde copolymer and potassium acrylate and how these could improve a lettuce crop (Lactuca sativa L.) implantation and growth under controlled conditions. Two treatments with 25 and 50 kg. ha-1 doses versus a control sample were compared in order to determine if the use of said amendment could improve crop production. The emergence, survival, fresh and dry weight of the aerial part of the crop and the soil humidity levels were evaluated. The answers were positive for the application of the amendment in the lower dose since the emergence of seedlings, its survival, its growth and its consequent yield raised, as well as the moisture content of the soil. In conclusion, the application of 25 kg ha-1 of the copolymer in the of the lettuce crop site, improved the growth and increased its yield.
