Abstract
In the highland regions of the state of Santa Catarina, where Curitibanos is located, there is a period of time during the year when farmers usually don t grow any crops in their lands. This period goes from February when they harvest their soybean or common bean fields to July, when farmers start to sow wheat fields. Based in the knowledge that canola can adapt to high temperatures there is a possibility for growing this crop during this time window. Therefore this project had the objective of studying canola adaptation in safrinha conditions in the highland regions of Santa Catarina. The study was conducted in the experimental area of the Federal University of Santa Catarina Curitibanos between September of 2015 and July of 2016. The experiment was conducted with a split-plot design with main plots arranged in a randomized block design, with four replications. The entries in the main plots were formed by the sowing dates of canola after harvesting the summer crops (soybeans and common beans) sowed in October 10th and November 10th of 2015. The entries in the subplots were formed by three canola hybrids in succession to the summer crop. In the summer crops, number of days from emergence to flowering and from flowering to physiological maturation, production components and yield were evaluated. For safrinha grown canola the evaluations were: duration of development phases, biometric characteristics, components of production and yield. The data was submitted to analysis of variance by the F test (p < 0.05) and when significant differences were present, the average values were compared by t test (p <0.05). In conclusion, this study showed that canola hybrid Hyola 411 sown on February 2nd, 2016 has presented good potential for cultivation due to its early cycle. Additionally, more studies are necessary to fully analyse the adaptation of canola in safrinha conditions.
