Abstract

The management of stem depth in planting of sugar cane advances the quick establishment of crop in the field. The objective of this work was to known the effects of the depth planting and regions of stem in morphological characteristics that affect the initial development of different phenological cycles by genotypes of sugar cane. The experimental design was the randomized blocks, with three replications in a factorial design 3x3x2, to depth planting (15, 30 and 45 cm), region of stem used in planting (basal, middle and apical) and genotypes (RB855156 and RB72454). The depth planting determined the speed of growth with emergency by shoot genotypes of the sugar cane and tillering of plant in initial development. Furthermore, in this work was found that the apical region of the stem by early genotype RB855156 was better tillering, more sprouting, an plant height in relation to late genotype RB72454.
