Growth rate, leaf area index, and productivity of jambu grown in a hydroponic system

Abstract

Jambu (Spilanthes oleracea L.) is a leafy vegetable with medicinal properties used in food, cosmetics, and medicine. This work aims to analyze the growth of jambu plants grown in a hydroponic system. The experiments were conducted at a company site (B&A Hidroponia), using a nutrient film technique hydroponic cultivation system, in a protected environment. The experimental design was randomized with six treatments and three replications. The morphophysiological indices, culture growth rate, relative growth rate, net assimilation rate, and productivity were analyzed. Crecism analysis showed that the jambu plant has higher morphophysiological indices after the 39-day cycle in a hydroponic system and was directly influenced by the liquid assimilation rate, which in turn is influenced by the duration of the leaf area. The producer must pay attention to the handling of the nutrient solution. A productivity of 11.39 Kg / m2 at 54 DAS of jambu cultivation was achieved using hydroponics.
