CAPONE, Aristoteles et al. Effect of sowing time on off-season sunflower crop, in succession to soybean in Cerrado soil of Tocantins, Brazil. Rev. Ceres [online]. 2012, vol.59, n.1, pp.102-109. ISSN 0034-737X.

Sunflower (Helianthus annuus L.)is highly tolerant to drought, cold and heat, thus, it becomes favorable to off-season crop. The objective of this study was to evaluate the performance of sunflower cultivars in four no-till planting times into soybean straw during the off-season 2009, in Southern Tocantins State, Brazil. The experiment was arranged in a randomized block design, with 20 treatments and three repetitions.Treatments were arranged in a 4 x 5 factorial, with four sowing times: ST1 (03/15/2009), ST 2 (28/3/2009), ST 3 (04/09/2009) and ST 4 (01/05/2009); with five cultivars: H250, H251, H358, H360 and H884, into soybean straw. There was significant interaction between times and cultivars for all the characteristics evaluated. Sowing delay reduced the means of all characteristics evaluated, except for hectolitre weight. The highest yield was obtained with the treatment ST 1. Cultivar H884 had the best performance for most of the variables analyzed.
