Abstract
The purpose of this work is to analyze lettuce cultivars different responses to environmental adaptability and rock dust concentrations in agroclimatic conditions in the south-west region of Goiás state. The work was conducted in the county of Mineiros, Goiás. The experimental area soil’s was classified as quartzarenic NEOSOL. In experiment number 1, was used experimental design in random blocks in factorial 5 × 2, corresponding to five rock dust concentrations (0, 100, 200, 300 and 400 kg ha-1), in two lettuce cultivars of Crespa and Americana lettuce. In experiment number 2 was applied experimental design in randomized blocks, which were constituted by 7 lettuce cultivars (Hanson, Simpson S. Preta, Baba de Verão, Maravilha de Inverno, Grandes Lagos, Crespa Palmas, and 4 Estação). The data results were analyzed 45 days after seeds transplant. The results were submitted to variance analysis and Turkey’s regression and test at a 5% probability. The 400 kg ha-1 rock dust dose didn’t have any effects in lettuce cultivars Crespa and Americana, once that, rock dust nutrients mineralization occurs very slowly, not interfering in the lettuce first cycle. 4 Estação cultivar presented good environmental adaptability to Goiás south-west agroclimatic conditions, more specifically in Mineiros, where it is recommended lettuce cultivation in summer-fall.
