RESUMO:

Safflower is an oilseed with energy potential, tolerant to adverse climatic conditions such as high temperature and water restrictions, which has the potential to be cultivated during the second harvest period in the Central-West region of Brazil, where we have cultivation restrictions due to the reduction rain and rising temperatures. Safflower cultivation is recent in the State of Mato Grosso, requiring more studies regarding the cultivation system and in this sense, this study intended to evaluate nine safflower genotypes in different spacing between planting rows. The experiment was conducted in the experimental area of the Genetic Resources & Biotechnology Laboratory (LRG&B) at UNEMAT, in Cáceres-MT, evaluating nine safflower genotypes in four row spacings (0.30 m; 0.45 m; 0.60 and 0.75 m), in a 9x4 factorial scheme, in a randomized block design, with three replications. Nine variables were evaluated, namely: Flowering; Number of branches per plant; Number of chapters per plant; Plant height; Diameter of chapters; Number of seeds per chapter; Weight of 1000 seeds; Crop cycle and productivity per plant. The data obtained were subjected to analysis of variance, with subsequent use of the Skott and Knott mean grouping tests and regression. The results showed significant differences at 1 and 5% probability between the genotypes and for the spacings evaluated, where no significant interaction between the factors was found. The factors were evaluated individually and for the genotypes, PI 568870 and PI 613361 showed a shorter cultivation period, while for the production components (NCP, NRP, DCAP, NSC, P1000, and PROD) PI 405970 and IPR 221 expressed performance superior agronomic. For the spacings evaluated, the genotypes showed better performance in DCAP, P1000 and PROD at a spacing of 0.60 m, while at a spacing of 0.30 m the agronomic performance was not adequate for the genotypes PI 405970, PI 393500 and IPR 221.
