GROWTH AND YIELD OF CONILON COFFEE IRRIGATED BY SUBSURFACE
DRIP IRRIGATION WITH BRACHIARIA IN BETWEEN THE ROWS; Advisor: Robson
Bonomo, Co-advisor: Waylson Zancanella Quartezani.
Coffee is an important Brazilian agricultural commodity, with the varieties Coffea
arabica (Arabica Coffee) and Coffea canephora (Conilon Coffee and robust), the most
consumed coffees in the world. Given the importance of culture, technologies such as
the use of subsurface dripping associated with the use of cover plants between the
lines of the coffee tree have gained ground in the field, with the premise of achieving
greater efficiency in the use of water and reducing damage caused by cultural
treatments, increasing system life and reducing costs. Thus, the objective was to
evaluate the production and vegetative growth of Conilon coffee genotype 153,
managed with and without brachiaria between the lines, and with the use of a dripper
at different depths in relation to the soil surface, in the northern region of Espírito Santo.
The experimental design used was in randomized blocks (DBC), with four replications
and five plants per plot, in a split plot arrangement, with the plot being the types of
management between the lines of the coffee tree (with brachiaria and traditional), and
the subplots depths dripper tube in relation to the soil surface (superficial, 0.08 m and
0.16 m). Growth evaluations were carried out on plants 11 months after transplanting,
in three useful plants per plot every 60 days, totaling five evaluations. The measured
response variables were: morphological, total growth, daily rates of growth of the
orthotropic and plagiotropic branch and productivity and yield of processed coffee
beans. The cultivation of brachiaria between the lines and the use of the subsurface
dripper did not limit the growth rate of the coffee tree, both in the winter and in the
summer. The use of subsurface drip provided greater vegetative growth of conilon
coffee. The intercropping with the brachiaria associated with subsurface drip provided
greater vegetative growth of the branches, but resulted in less productivity. Higher
coffee bean yield was obtained when surface drip was used.
Key words: Coffea Canephora, ground cover, subsurface irrigation.
