Résumé:
This study was carried out to evaluate the influence of water stress on Coffea
arabica plants, variety “catuaí 44”, assayed with two levels of waterabsorbent. 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 30 to 60 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. Thirty days after transplant, water stress was initiated and after 60 days, the follow
parameters were evaluated: foliar area, canopy dry matter and root system dry matter. It was
observed to canopy dry matter a reduction in SSH levels from DH1 to DH0 of 40.29%. This was
not observed to SCH levels, with DH1 and DH0 without statistic difference. To foliar area and
root system dry matter there was no significantly difference.
