Avaliação do efeito de polimero hidroretentor na produtividade do rabanete

Abstract

The cultivation of vegetables is characterized as a highly intensive activity in the use of the soil, water, inputs and labor. These plants usually present short cycle, becoming an activity with fast economic return. With the need to increase food production, cooperatives and producers have been encouraged to seek alternative techniques to improve productivity and reduce costs. In this way, the hydroelectric polymers began to be investigated as a way of minimizing the problems associated with the low productivity, usually caused by the irregular or deficient availability of water and bad structuring of the soil. The objective of this work was to evaluate radish productivity, submitted to different doses of water-retaining polymer, and to different water slides. The design was in a 3X2 factorial scheme, with three irrigation slides (50%, 75% and 100% Eto) and two hydrogel doses (40 and 60 g / m2) with four replications. The parameters of leaf number (leaves plant-1), horizontal and vertical root diameter (mm), total and shoot length (cm), fresh root and shoot mass (g) and dry mass of Root and aerial part (g). All variables were submitted to analysis of variance by Tukey test at 5% probability. As a result it was obtained that radish root production was influenced by the applied water slides being significant all the variables and some variables influenced by the doses of hydroelectric polymer as total length (CT) and aerial part (CPA) and dry mass Of the root (MSR).
