Abstract

The purpose of the work was to evaluate the effect of a hydroretentive polymer on coffee plants cultivated in pots in a greenhouse. The experiment was conducted in a 4 x 4 factorial design, with 4 rates of the polymer and 4 irrigation intervals. The depth of irrigation water, defined by evapotranspiration, was calculated with use of the class A pan evaporimeter. Plant response to treatments was determined by measuring plant height, stem diameter, number of internodes, leaf area, and root and shoot dry matter. The results indicated plant response was inversely proportional to irrigation intervals and directly proportional the quantity of the polymer.
