The evaluated treatments were: Biostimulant + chemical fertilization (T1), Chemical fertilization (T2) and Control (T3). A completely randomized design with three treatments and seven repetitions was used. Rhizomes weighing 200 g were used, which were sown in polyethylene containers, where they were allowed to emerge and grow until reaching 20 cm in height. Then the treatments were applied and the initial dry mass of the seedlings was recorded in order to measure the increase in growth due to the effect of the treatments. At 60 days after the first application of treatments, the foliar area, dry mass and Dickson's quality index were recorded. The data were subjected to analysis of variance and separation of means with Tukey's test (α <0.05). In addition, correlation analysis was performed between the growth and quality variables of the seedlings. The biostimulant + chemical fertilization increased the leaf area, dry mass and Dickson's quality index of the seedlings by 14.80, 11.22 and 7.56%, respectively, in relation to the chemical fertilization treatment. Dickson's quality index positively correlated with seedling growth. The use of biostimulant from seaweed extract was effective to improve the growth and quality of plantain seedlings in the nursery, and enhanced the effect of edaphic fertilization. |
