Abstract

  In the Brazil, the cultivation of pomegranate aroused interest in several producers of fruit, especially in the northeast. The objective of this study was to test the efficiency of the best dose of the extract of seaweed in the development of pomegranate trees seedlings. The experiment was conducted in a greenhouse at the Federal Rural University of Semi-Arid (UFERSA), Mossoro, RN. In the experiment, was used a randomized complete block design (RBD) with five doses (0, 2, 4, 6 and 8 ml L-1) of the seaweed extract and six replications; each experimental unit was composed of five plants. The application of bio-stimulant doses were started at 7 days after transplanting, and the extract applied in seven-day intervals with a syringe, pouring 15 ml of solution near the base of each plant until the end of the experiment. At 120 days after sowing the characteristics were evaluated: shoot length, root and total (cm); number of sheets (unit/plant), lap diameter (mm), dry mass of the stalk, the leaf, the shoot, root system and total (g). For further growth, dry biomass yield and better quality of pomegranate trees seedlings in nurseries, it was observed that the dose of 4.0 mL of biostimulants, promoted greater seedling growth.
