摘要

The cultivation of sunflower (Helianthus annuus L.) can be conducted in various times and locations during the crop year. I n state of Tocantins the culture can be explored in crop in cerrado region and in intercrop in sub-irrigated lowland. The objective of this study was to evaluate the effect of swing times in Gurupi-TO and Formoso of Araguaia-TO, with five cultivars sunflower. It was installed four times in Gurupi-TO and one in Formoso-TO. The experimental design was randomized blocks, with 25 treatments and three replications. The was five times: EP1(24/11/2008), EP2(01/12/2008), EP3(18 / 12/2008) and EP4(12/30/2008) in Gurupi-TO and Formoso (07/04/2009) in Formoso do Araguaia-TO, with five cultivars: H250, H251, H358, H360 and H884. There was significant interaction between times and cultivars for the traits: flowering, plant height, normal achene, weight of thousand achene, hectolitre weight and productivity of achenes. In Gurupi-TO, there was a negative influence for all the avaluated traits as the sowings were delayed, It accurred because of the incidence of Alternaria helianthi. Productivity close to 3000 kg ha -1 was obtained in Gurupi (EP1) and the intercrop in Formoso do Araguaia. The most productive cultivars were the H251 and H358, when cultivated in EP1 and EP5. Key-words: Cerrado, Helianthus annuus L, lowland
