Densidades de plantas, amontoas e tipos e tamanho de propagulos na produtividade e rentabilidade da araruta ‘comum’

Abstract

Among the cultural practices for the cultivation of vegetables stands out the population of plants and the heap, which have a marked effect on the production. In addition, for species propagated by seedlings, it is important to know the type and the way it should be planted, in order to establish the appropriate final population as soon as possible. This is because in any economic activity is essential the study of profitability that can be decisive for the success of the producer. The objective of this study was to evaluate the density of plants and the number of clumps influencing the productivity and profitability of 'Comum' arrowroot, when propagated with different types and sizes of propagules. Two experiments with araruta plants were implemented between October 2014 and August 2015. For the first study, arrowroot plants with different spacings between plants (20, 25, 30 and 35 cm) and numbers of plants (0, 1 and 2). The factors under study were arranged as a 4 x 3 factorial, in a randomized complete block design, with twelve treatments and six replications. In the second experiment propagated araruta plants with different types (apex and base) and propagule sizes (T1, T2, and T3) were grown. The factors under study were arranged as a 2 x 3 factorial, in a randomized complete block design, with 6 treatments and four replications. It was concluded that the spacing of 20 cm is the most adequate for yield and gross income, and seedlings from the apex and size T 1 should be used for planting.
