Summary: The objective of this work was to evaluate the vegetative development of the coffee
tree Conilon, irrigated by drip irrigation in coastal board soil, submitted to different
irrigation slides at different positions in relation to the soil surface. The work was
carried out at the experimental farm of the University Center North of Espírito Santo
of the Federal University of Espírito Santo in the municipality of São Mateus-ES. The
experimental design was a randomized complete block design in a plot plot
subdivided in time. The treatments were distributed in relation to the hose position
(0.2m of the surface planting line, 0.2m of the planting line and 0.1m of depth, and
0.2m of the planting line and 0.2m of depth ) and water slides consisting of 100, 73
and 45% of the slide applied in conventional treatment. The vegetative growth
characteristics as well as the growth rates between the measurements were
evaluated and submitted to analysis of variance and, because of the significance for
the variables, the mean test was applied. The reduction of 27% of the water layer
applied through a subsurface irrigation system at 0.2m from the planting line and at
0.1m depth did not limit the vegetative development of the "143" genotype at 13
months of age. The 0.2m depth of the drip tube applying 73% of the leaf consumed
limited only the mean number of orthotropic knots in the initial formation of the
Conilon coffee plant. The reduction of 55% of the applied irrigation depth, regardless
of the depth, was detrimental to the vegetative development of Conilon coffee at 13
months of age. The growth rate of plant height is increasing until the flowering of the
coffee plant Conilon, in contrast the growth rate of the plagiotropic branch is
presented in a descriptive way.
