Water stress along the radish crop cycle may interfere with its development, causing changes in morphology, interfering with the biochemical reactions of the plant. The objective of this work was to evaluate the productive yield of radish (Raphanus sativus L.) cultivated under different irrigation depths and fertilization qualities, from September to December 2019, in the Serra Talhada Academic Unit - UFRPE/UAST. The design adopted was in a factorial scheme (5 x 3) x 4 consisting of five irrigation depths (50, 75, 100, 125 and 150% of The ETc), three sources of fertilization (two organic sources and one mineral source as control treatment) and four replications, in randomized blocks with arrangement of subdivided plots. Campaigns were carried out to obtain biometric and biomass data. Of the biometric parameters, the following parameters were analyzed: shoot height, number of leaves, plant weight, commercial diameter, root system length and root weight. Biomass was performed to determine the efficiency of water use. The irrigation depth of 113.2% of the ETc provided higher production of the commercial part of the radish. It was found that the efficiency of water use is maximized with the use of smaller irrigation depths. It is feasible to partially or fully replace mineral fertilization with organic fertilization for the production of radish.
