CONSUMO HÍDRICO DE CRAVINA SUBMETIDA A DIFERENTES ESTRATÉGIAS DE IRRIGAÇÃO E TAMANHOS DE VASO

Abstract

The aim of this research was to evaluate Dianthus Melody (Dianthus hybrida 'Melody') water consumption and stalk growth when submitted to different irrigation strategies and pot sizes for one crop cycle. Conducted in a greenhouse at the department of phytotechny, Universidade Federal de Santa Maria, Santa Maria, Rio Grande do Sul, Brazil, the experiment was designed as a 2x4 factorial arrangement with two pot sizes and four irrigation strategies per treatment with five replications each. At the end of the growth cycle stem height, number of buds, number of nodes per stem, number of branches per stem, stem diameter as well as the fresh and the aboveground dry stem phytomasses were evaluated and also was determined the water consumption over the cycle. The results showed an increase in water consumption during the growth stage however treatments had no effect on the evaluated productivity parameters.
