Abstract:
Background and Objective: Upland cotton is one the main crops of economic importance in Brazil. In the face of such morphological traits, there is the need to search for cotton cultivars that are adapted to the smaller row spacing, as these can be grown in succession to soybean without the need to exchange of the seeder. However, few results encourage this practice by farmers. The aim of this study was to evaluate the agronomic performance of 16 upland cotton cultivars grown in two row spacing in the Brazilian Cerrado region. Methodology: The trial was conducted at Fundação Chapadão, in the municipality of Chapadão do Sul, State of Mato Grosso do Sul, Brazil. Experimental design was sub-divided plots with ten lines each, with four replications. The following agronomic traits were evaluated: Plant height, first reproductive branch height, number of bolls per plant, weight of bolls per plant and cotton yield in seed. Results: There were significant differences (p = 0.05) between cultivars for all evaluated traits. Except for the WB, the others traits were influenced by spacing. There was no interaction between factors for any evaluated traits. Conclusion: Spacing of 0.90 m provides better agronomic performance of cotton cultivars. The cultivars FM975, TMG41 and TMG81 stood out among the others for obtaining the highest cotton yield in seed, alternatives to the growing for farmers from Brazilian Cerrado region.
