Abstract

As a crop of excellent importance, cassava (Manihot esculenta Crantz) is one of the main crops present in Brazilian family farming, and one of the factors that contribute to this picture is the great diversity of products that the cassava plant can offer. The cultivation of cassava is carried out from manioc. However, there is a big difficulty to find maniocs with quality guarantee and in satisfactory quantities in the planting moment. It also presents a high cost of transportation due to the large quantity of material demanded for the planting. For that matter, the costs for the planting could be reduced if the maniocs were smaller, using less volume of propagation material, which is an example of what happens with the sugarcane crop that tends to develop encapsulation technologies for the plant material. Therefore, the objective of this work was to evaluate different sizes of cassava propagation material, along with the possible encapsulation with wax. The experimental design used was a randomized block design (RBD). With 10 treatments and 4 blocks, totaling 40 experimental units. Hypothesis and regression tests were performed to compare the treatments. The treatments were arranged in a 2 x 5 factorial schedule. The first factor, allocated to the plots, was composed of encapsulation and non-encapsulation with wax. The second factor, allocated in the subplots, was made up of different sizes of billets, with 2, 4, 6, 8 and 10 buds. The second factor, allocated in the subplots, was made up of different sizes of billets, with 2, 4, 6, 8 and 10 buds. With this study, we can say that, in general, the sizes of manioc bigger seeds showed a better development, that is, it is not indicated to use material for the propagation with two buds. The encapsulation did not interfere negatively in the variables, but also did not present the satisfactory results in the way it was evaluated.
