Resumen:
This study was carried out to evaluate the influence of waterabsorbent on Coffea
arabica plants, variety “catuaí 44”, assayed with two levels of water stress. The experiment was
conducted in a fatorial design 2 x 2, with two levels of water stress: DH0 (without water stress)
and DH1 (water stress from 60 to 90 days after plant transplant) and two levels of waterabsorbent:
SSH (soil without waterabsorbent) and SCH (soil with 5 g of waterabsorbent per recipient,
according to field recommendations), in a completely randomized design, with 3 replications.
Sixty days after transplant, water stress was initiated and after 30 days, the follow parameters
were evaluated: canopy diameter, foliar area, canopy dry matter and root system dry matter. It
was observed to canopy diameter, foliar area, canopy dry matter to SSH levels a reduction from DH1 to DH0: 32.38%, 79.47% and 51.12%, respectivelly. However, to SCH levels, the reduction was:
21.14%, 78.76% and 48.95%, respectivelly. To root system dry matter there was significantly differences
at the evaluated levels.
