Produção de alface-crespa hidropônica sob doses de fertilização foliar fosfatada

Abstract

This work aimed to evaluate the production of hydroponic curly lettuce by applying foliar phosphate fertilizer. The research was carried out in a greenhouse in the rural area of Pato Branco-PR during the year 2021. All production and the nutrient solution occurred in the property standard, carried out in the NFT system, where only foliar fertilization phosphate was added to vegetables. The experiment was conducted in a randomized block design with four replications, with five different treatments, applying doses of 0, 1, 2, 3, and 4 g/L of phosphate foliar fertilizer, with an interval of seven days for each application. At the end of the crop cycle, root length (CR), stem diameter (DC), fresh matter mass (MMF), and plant dry matter mass (MMS) were evaluated. An increase in the MMS of the plants was observed according to the more significant addition of phosphate fertilizer through the leaves. No effective results were found for the other growth and yield variables.
