Influência do déficit hídrico sobre plantas de café submetidas a dois níveis de hidroabsorvente.

Abstract

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.
