- Abstract
The management of irrigation in flower cultivation is relevant especially in a protected environment, where production depends exclusively on irrigation water. The objective of this work was to determine technically and economically the effect of irrigation on the production of cut gerbera in a protected environment. The experimental design was completely randomized, with five treatments, being 120%, 100%; 80%; 60% and 40% of vessel retention capacity, and ten replicates. The components of production of the cutting gerbera were evaluated, as well as the maximum technical efficiency (MET), from the results of rod production and the maximum economic efficiency (MEE), from the equation that corresponds to the optimum blade that maximized the revenue, considering the factors of water price and product price (stems). The results showed that water availability of 80% and 100% is required to produce long and firm stems, which directly reflects the quality of the final product. The MET for the production of gerbera was observed for the blade of 79.3% of vessel retention capacity and the blade of MEE of 70.6 mm.
