Produção de manjericão na primavera verão em sistemas de cultivo e adubações

Abstract

The cultivation of basil is intended for marketing the plant as a condiment and in the production of essential oil Factors such as growing season, fertilization and cultivation system influence the yield of the plant. The study aimed to produce basil (Ocimum basilicum L.) to grow Cinnamon simultaneously in the field and in a protected place/greenhouse, in the spring - summer season using mineral, organomineral and organic fertilization in order to evaluate these isolated factors or the interaction between them in the production, content and composition of essential oil. The experiment was carried out in the city of Uberlândia on the experimental farm called Glória between April 2017 and July 2017. The experimental design used was the randomized block (DBC), in a factory scheme (2 x 4), in two environments (greenhouse and field) e four types of fertilization, with a total of 8 treatments, in 4 repetitions. The cultivation used was Cinnamon, and the experiments were conducted and installed simultaneously in the field and greenhouse. The harvest took place when the plants were in full bloom. The variables analyzed were plant height, dry and fresh mass of leaves and flowers, content and composition of essential oil. For the averages of SPAD index, plant height, leaf length and width, there was no interaction for the evaluated factors. Plants fertilized with organic sources and grown in a greenhouse showed superior yield in relation to field cultivation for the variables fresh mass of leaves and flowers, dry mass of leaves and flowers and essential oil yield. The main compounds found in the essential oil wew linalool and (E) –cinnamate, grown in the field and greenhouse.
