Abstract

Roses are the main exploitation in ?oriculture in Brazil. The lack of information on the quantity of water applied along the phenological development stages of the plants, as well as defcient or excessive nutrient application to the plants may provide unfavorable conditions for rosebush development. This study aimed to make a technical and economical evaluation for rose production in terms of irrigation and nitrogen. The experiment was conducted in a greenhouse and consisted of a randomized block design with split plots. These plots were defned by four irrigation depths (40, 70, 100 and 130%) and the subplots by four recommended nitrogen levels rate for rosebushes (40, 70, 100 and 130%), with four replications. The irrigation management was performed with tensiometers installed at the experimental treatments of 100% irrigation depths. Rose productivity decreased due to water defcit or excess; nitrogen rates did not affect the qualitative parameters of the buds; the irrigation depth that provided the maximum economic and technical effciencies were nearly identical.
